    <p>Tiopronin is a key drug used to treat cystinuria. A 41-year-old Japanese woman with cystinuria presented with eyelid edema and weight gain after the administration of tiopronin. Her serum albumin was 1.8 g/dL and her urinary protein level was 5.5 g/gCre. After cessation of tiopronin, she achieved remission of nephrotic syndrome (NS). Secondary NS due to tiopronin was evident based on the clinical course and laboratory values. A kidney biopsy showed membranous nephropathy (MN), and an immunofluorescence analysis revealed strong deposition of immunoglobulin G4 (IgG4). However, a previous case report of tiopronin-induced MN showed staining for IgG1 and IgG3. This case report suggests a novel etiology for tiopronin-induced MN. </p>

    <p>A 34-year-old Japanese man presented with blurred vision, headache, nausea, anemia, thrombocytopenia, and severe renal dysfunction. Thrombotic microangiopathy was initially suspected to have been caused by malignant hypertension. Antihypertensive medications did not improve his thrombocytopenia or renal dysfunction, and other diseases causing thrombotic microangiopathy were ruled out. Therefore, the patient was diagnosed with atypical hemolytic uremic syndrome. A renal biopsy revealed an overlap of thrombotic microangiopathy and C3 glomerulopathy. Genetic testing revealed c.848A>G (p.Asp283Gly), a missense heterozygous variant in the gene encoding complement factor I. Overlapping atypical hemolytic uremic syndrome and C3 glomerulopathy with complement factor I mutation is very rare, especially in Japan. </p>

    <p>Myoglobin is a well-known cause of acute kidney injury (AKI) due to rhabdomyolysis. However, whether or not removing serum myoglobin by on-line hemodiafiltration (OHDF) improves the kidney function remains unclear. We herein report a patient with a history of methamphetamine abuse who developed AKI due to rhabdomyolysis. A urinalysis and blood collection results obtained before and after OHDF demonstrated that OHDF improved the kidney function by removing a large amount of serum myoglobin rather than via urinary excretion. In conclusion, OHDF may prevent AKI progression effectively when the urine volume is insufficient. </p>

    <p>Fabry disease is an X-linked lysosomal storage disorder due to mutations in the alpha-galactosidase A gene, which leads to the accumulation of globotriaosylceramide in various organs. In Fabry disease with end-stage renal disease (ESRD), cerebrovascular events are lethal, even with enzyme replacement therapy (ERT). However, the utility of biomarkers to evaluate the ERT response is unclear. We herein report a case of recurrent cerebrovascular complications under ERT in a Fabry disease patient, progressing to ESRD on peritoneal dialysis. Further studies are warranted, but Fabry disease patients with ESRD receiving ERT might need careful long-term follow-up in cases with cerebrovascular manifestations. </p>

    <p><b>Objective </b>Although the coronavirus disease 2019 (COVID-19) Omicron variant causes less severe symptoms than previous variants, early indicators for respiratory failure are needed in hemodialysis patients, who have a higher mortality rate than the general population. Liver chemistries are known to reflect the severity of COVID-19 in the general population. This study explored the early indicators for worsened respiratory failure based on patient characteristics, including liver chemistries. </p><p><b>Methods </b>This retrospective study included 117 patients admitted for COVID-19 during the Omicron wave. Respiratory failure was defined as oxygen requirement during treatment. Information on the symptoms and clinical characteristics, including liver chemistries [aspartate aminotransferase (AST) and alanine aminotransferase (ALT)], at admission was collected. </p><p><b>Results </b>Thirty-five patients (29.9%) required oxygen supply during treatment. In the multivariate logistic regression analyses, AST [odds ratio (OR) 1.06, 95% confidence interval (CI) 1.00-1.13, p=0.029], ALT (OR 1.09, 95% CI 1.02-1.18, p=0.009), and moderate COVID-19 illness (Model including AST, OR 6.95, 95% CI 2.23-23.17, p<0.001; Model including ALT, OR 7.19, 95% CI 2.21-25.22, p=0.001) were independent predictors for respiratory failure. Based on the cutoff values determined by the receiver operating characteristic curve, higher AST (≥23 IU/L) and ALT levels (≥14 IU/L) were also independently associated with respiratory failure (higher AST: 64.3% vs. 18.8%, OR 3.44, 95% CI 1.08-11.10, p=0.035; higher ALT: 48.8% vs. 19.7%, OR 4.23, 95% CI 1.34-14.52, p=0.013, respectively). </p><p><b>Conclusion </b>The measurement of AST and ALT levels at baseline may help predict oxygen requirement in hemodialysis patients with COVID-19. </p>

    <p>Fabry disease is a rare X-linked lysosomal storage disorder caused by mutations in the alpha-galactosidase A (GLA) gene that results in deficiency of the enzyme GLA and leads to the accumulation of globotriaosylceramide (GL-3) in cells. The accumulation of GL-3 may lead to life-threatening complications. Significant advances in genetic sequencing technology have led to a better understanding of genotype-phenotype interactions in Fabry disease. Fabry disease with an R112H mutation is known as the non-classic type. However, the long-term clinical course of the disease remains unknown. We herein report a patient with a 30-year natural history of non-classic Fabry disease with an R112H mutation. </p>

    <p><b>Objective </b>The National Kidney Foundation (NKF) Kidney Disease Outcome Quality Initiative (KDOQI) guidelines have recommended the use of arteriovenous fistula (AVF) at the initiation of dialysis. However, there are significant differences in the dialysis environments of Japan and the United States, and there are few people who receive hemodialysis via a central venous catheter (CVC) in Japan. The aim of the present study was to examine the association between the type of vascular access at the initiation of dialysis and the incidence of mortality in Japan. </p><p><b>Methods </b>This study was a prospective, multicenter, cohort study. The data was collected by the Aichi Cohort study of Prognosis in Patients newly initiated into dialysis (AICOPP) in which 18 Japanese tertiary care centers participated. The present study enrolled 1,524 patients who were newly introduced to dialysis (the patients started maintenance dialysis between October 2011 and September 2013). After excluding 183 patients with missing data, 1,341 patients were enrolled. The Cox proportional hazards model was used to evaluate mortality based on the type of vascular access. The types of vascular access were divided into four categories: AVF, arteriovenous graft (AVG), CVC changed to AVF during the course (CAVF), CVC changed to AVG during the course (CAVG). </p><p><b>Results </b>A multivariate analysis revealed that AVG, CAVF and CAVG were associated with a higher risk of mortality in comparison to AVF [hazard ratio (HR), 1.60; p=0.048; HR, 2.26; p=0.003; and HR, 2.45; p=0.001, respectively]. </p><p><b>Conclusion </b>The research proved that the survival rate among patients in whom hemodialysis was initiated with AVF was significantly higher than that in patients in whom hemodialysis was initiated with AVG or CVC. </p>

    <p>To date, a recognized treatment for refractory membranous nephropathy (MN) has not been established. Recently, several reports have indicated the efficacy of rituximab as a novel treatment option. However, only a few published accounts exist of rituximab therapy for idiopathic MN (IMN) in the Asian population. We present the cases of three IMN patients who were treated with single-dose rituximab after they showed no response to conventional therapies, including corticosteroids, cyclosporine, cyclophosphamide, mizoribine, and mycophenolate mofetil. Although one case showed no response, a complete or incomplete remission was achieved in the other two cases. Rituximab may therefore be a beneficial treatment option for IMN. </p>

    <p>Selenium is essential for human health; its deficiency leads to cardiac dysfunction. We herein report a 79-year-old man on peritoneal dialysis who presented with refractory hypotension caused by selenium deficiency. He was admitted to our hospital with bacterial pneumonia and hypotension and abnormal electrocardiogram (ECG) findings. Despite improvement of pneumonia, his hypotension continued, and intravenous noradrenalin could not be discontinued. His serum selenium level was extremely low, and he was started on intravenous selenium. His hypotension and ECG findings gradually improved, and noradrenalin was discontinued. Physicians should consider selenium deficiency when patients on PD show refractory hypotension. </p>

    <p><b>Objective </b>In patients on peritoneal dialysis (PD), it was reported that colonoscopy, but not upper gastrointestinal endoscopy, could cause peritonitis as a complication. A guideline of the International Society for Peritoneal Dialysis recommends preemptive intravenous antibiotics administration of ampicillin and aminoglycoside with or without metronidazole, to prevent colonoscopy-associated peritonitis. In this study, we retrospectively evaluated the effects of preemptive antibiotics therapy by oral administration instead of intravenous administration. </p><p><b>Methods </b>We investigated the incidence of colonoscopy-associated peritonitis in a single center. In 170 patients undergoing PD between January 2010 and December 2019, 50 colonoscopies were performed, including 49 with oral administration of amoxicillin and ciprofloxacin and/or metronidazole as preemptive therapy 1 hour before the colonoscopy procedure, and 1 without. </p><p><b>Results </b>We observed no incidence of colonoscopy-associated peritonitis. </p><p><b>Conclusion </b>Generally, oral administration of preemptive antibiotics is less painful and more convenient than intravenous administration, especially in outpatient procedures, such as a colonoscopy. Our results suggest that oral antibiotic administration might be effective for preventing colonoscopy-associated peritonitis in PD patients. </p>

    <p>Nontyphoidal <i>Salmonella</i> is a common cause of bacterial gastroenteritis, occasionally causing bacteremia. We herein report the case of an 80-year-old man who presented with bacteremia and pre-renal acute kidney injury (AKI) secondary to diarrhea caused by nontyphoidal <i>Salmonella</i>. Despite AKI improvement on fluid administration, some serological abnormalities, such as hypokalemia, hypophosphatemia, and hypouricemia, and abnormal urinary findings emerged, including renal glycosuria and aminoaciduria. Fractional excretion of phosphate and uric acid was increased, suggesting that the serological and urinary abnormalities may have arisen from Fanconi syndrome. Physicians should consider acquired Fanconi syndrome when patients with nontyphoidal <i>Salmonella</i> bacteremia present with electrolyte disorders. </p>

    <p><b>Objective </b>Metabolic syndrome represents a unified condition of atherosclerotic diseases caused by abdominal obesity. The aims of this study were to examine the applicability of the prevalent fixed cut-off values of the abdominal circumference (AC) and body mass index (BMI) to age and gender groups and to identify suitable lifestyle modification factors. </p><p><b>Methods </b>We defined an outcome as having ≥ 2 risk components that are necessary to diagnose metabolic syndrome and examined the cross-sectional association of the AC and BMI with the outcome. We also assessed the effects of time-updated lifestyle information on metabolic traits using longitudinal data. </p><p><b>Patients or Materials </b> We enrolled 2,2953 beneficiaries of a corporate health insurance scheme who underwent annual health examinations between January 2004 and December 2014. </p><p><b>Results </b>The AC (per 5-cm increase, odds ratio [OR] 1.17, 95% confidence interval [CI] 1.12-1.24) and BMI (OR 1.10, 95% CI 1.07-1.14) were significantly associated with the outcome, adjusted for age, gender, current smoking status, drinking habits, and other lifestyle information. The association between the outcome and AC was modified by gender (P for interaction = 0.033), and the association between the outcome and BMI was modified by age group (P for interaction = 0.049). In the longitudinal analysis, current smoking, drinking habits, and unhealthy eating habits were associated with an increased AC and BMI, whereas regular physical activity was associated with a decreased AC and BMI. </p><p><b>Conclusion </b>We showed that the association between the AC or BMI and metabolic syndrome was modified by gender or age group. Further studies will be needed to customize the national health screening and education programs. </p>

We built the experimental setup of elemental model, which could simulate the steeper surge from SiC device inverter and construct the stator insulation system inside the motor core to control the insulation sheets configuration. By revealing the quantitative conditions of the carbonization generation, we verified that the voltage to suppress the carbonization generation depended on the location of the mold release layer. Therefore, we developed the guideline of insulation design to prevent the carbonization for the steeper inverter surge.</p>

    OBJECTIVE: Renal ischemic reperfusion injury (IRI) is unavoidable and is still one of the major problems in renal transplantation. The aim of this study was to investigate the effects of olprinone, a phosphodiesterase III inhibitor, on renal IRI. METHODS: After a right nephrectomy, renal IRI was induced in rats. Olprinone was given in two different ways: sustained systemic administration and transient local administration to the kidney. Control rats were treated with saline. Using a magnifying endoscope, the renal blood flow speed was measured at 23 h after reperfusion. Then, blood samples were collected, and kidney specimens were taken for histological study. In order to study the mechanism, we performed in vitro experiments, using human proximal renal tubular cells (HK-2) incubated with tumor necrosis factor (TNF)-alpha along with olprinone or saline, and interleukin (IL)-8 was measured in the culture supernatant. RESULTS: In the saline group, the blood flow speed (BFS) was greatly reduced compared to that in normal kidneys. In both olprinone-treated groups, BFS of the renal microcirculation significantly increased, tubular damage and macrophage infiltration attenuated, and renal function greatly improved. Olprinone inhibited the increase in the IL-8 levels resulting from the incubation of HK-2 with TNF-alpha. CONCLUSIONS: Our study successfully demonstrates that olprinone has renoprotective properties when applied locally as well as systemically. The results suggest that olprinone might be clinically useful in renal transplantation for the donor kidney, the recipient, and even in treating acute renal failure.

    BACKGROUND: Patients receiving hemodialysis for end-stage renal disease (ESRD) are at high risk for death from ischemic heart disease (IHD). Nicorandil, a hybrid compound of adenosine triphosphate-sensitive potassium channel opener and nitric oxide donor, has been reported to improve the clinical prognosis of patients with IHD. OBJECTIVE: This study sought to investigate the efficacy of oral nicorandil in reducing the risks for cardiovascular events (CVEs) and CVE-related death in patients receiving hemodialysis for ESRD after undergoing percutaneous coronary intervention (PCI) for angina pectoris. METHODS: For this retrospective chart review, we used data from telephone interviews and medical charts from 3 hospitals in Japan. Data from patients aged <80 years who were receiving hemodialysis for ESRD and who had undergone successful PCI for angina between January 1999 and December 2004 were included in the analysis. Patients were stratified based on status of nicorandil treatment before PCI, as follows: patients receiving nicorandil 5 mg PO TID (the recommended dosage in Japan) for >1 month before PCI (nicorandil group) or those who did not receive nicorandil (control group). We investigated 6-year follow-up data on the primary end point, defined as CVEs (ie, unplanned hospital admission for worsening anginal status, or CVE-related death). The secondary end point was CVE-related death. After the data were initially analyzed, we performed a propensity-matched analysis to minimize selection bias. RESULTS: Data from 356 patients were included in the study (235 men, 121 women; mean [SD] age, 69 [9] years; mean [SD] weight, 52.3 [9.1] kg; nicorandil group, 198 patients; control group, 158 patients). According to the estimated propensity scores, 107 patients from each group were matched. There were no differences between the 2 groups in the baseline characteristics. On propensity-matched patient analysis, the estimated rates of patients who were CVE-free at 6 years were 3

    BACKGROUND: Although the successful production of alpha1,3-galactosyltransferase-knockout (GT-KO) pigs has increased expectations of clinical xenotransplantation, additional modifications of genetically engineered pigs are still being explored, because even GT-KO pigs are incapable of inhibiting the host's immunological response completely. One of the potential candidates is a complement-regulatory protein, such as human decay-accelerating factor (hDAF). However, there are few reports on how high the expression level of hDAF in pig cells would be required for suppression of complement activation. The purpose of this study was to examine the relationship between the level of hDAF expression and its inhibitory effect on human serum cytotoxicity. METHODS: An expression (pCAGGS) vector containing the hDAF gene was transfected into pig fibroblasts using an electroporation system (Gene Pulser II). Forty-eight to fifty-two hours after transfection, the cells were stained with FITC-labeled anti-hDAF antibody and then applied to the cell sorter. hDAF-transfected cells with various expression levels were collected by gating on fluorescence intensity. The level of hDAF expression was determined relative to that in human control endothelial cells. Collected cells expressing x1, x5, x10, x15 and x30 hDAF were incubated into 96-well plates for 16 h, and the cells were subjected to 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl tetrazolium bromide (MTT) assay. RESULTS: hDAF expression levels in transfected cells at the time of MTT assay (16 h after sorting) were comparable to those immediately after sorting. hDAF expression in pig cells five times higher than in human endothelial cells was effective in inhibiting complement-dependent cytotoxicity of most human sera.

    It has been reported that percutaneous coronary intervention (PCI) is beneficial for coronary artery disease (CAD) among the general population. However, its effects in patients who are on hemodialysis (HD) remain unclear. A prospective cohort study was performed to clarify whether PCI has a therapeutic advantage over medical therapy among HD patients with CAD. A follow-up study to 5 yr was conducted among 259 HD patients with ischemic heart disease. Mean follow-up was 39 mo. Patients were divided into three groups: 122 patients without significant stenosis, 88 patients who had significant stenosis and were treated with PCI, and 49 patients who had significant stenosis and were treated with medication only. The primary end point was cardiac death, and the secondary end point was all-cause death. The results showed that the 5-yr cardiac survival rate was 41.6% in the medication group, 77.1% in the PCI group (P = 0.0006), and 84.5% in the nonstenosis group (P < 0.0001). The 5-yr all-cause survival rate was 19.3% in the medication group, 48.4% in the PCI group (P = 0.004), and 64.3% in the nonstenosis group (P < 0.0001). Even after adjustment for other risk factors, effects of PCI on the risk for cardiac and all-cause death remained significant and independent (odds ratio 0.14; 95% confidence interval 0.08 to 0.25, P = 0.0006; and odds ratio 0.37; 95% confidence interval 0.26 to 0.54, P = 0.0062, respectively). Results were consistent when the therapeutic effect of PCI or medication was analyzed using propensity-matched patients. These data suggested that PCI could improve the prognosis of HD patients with CAD. PCI would be recommended for HD patients with CAD.

    BACKGROUND: Heat shock proteins (HSPs) are well known as cytoprotective proteins. Geranylgeranylacetone (GGA), an antiulcer agent, has recently been shown to induce Hsp70. This study was performed to investigate the renoprotective properties of GGA. METHODS: The effect of GGA on the induction of the major HSPs (Hsp90, Hsp70, Hsc70, Hsp60, and Hsp32) was studied in the rat kidney or rat primary cultures of tubular epithelial cells (R-TECs) by Western blot. Localization of Hsp70 was determined by immunohistochemistry. The renoprotective effects of GGA were studied using a rat model of ischemia/reperfusion (I/R) injury. GGA (400 mg/kg), GGA with quercetin pretreatment (100 mg/kg), or a vehicle was given to rats 24 hours and again 1 hour prior to the induction of I/R injury. Rats were sacrificed at 24 hours after reperfusion. Histologic analyses and terminal deoxynucleotidyl transferase (TdT)-mediated deoxyuridine triphosphate (dUTP) nick-end labeling (TUNEL) assay were performed. Blood urea nitrogen (BUN) and serum creatinine was also measured. The cytoprotective properties of GGA were also studied in vitro by treating R-TECs with GGA (10 mumol/L) or a vehicle, followed by incubation in culture medium with oxidative stress condition (0.5 mmol/L hydrogen peroxide) or ischemic condition (2 nmol/L NaCN and 20 mmol/L 2-deoxyglucose in the absence of medium glucose). RESULTS: Oral administration of GGA induced Hsp70 expression in the kidney (which peaked at 24 hours) but did not induce Hsp90, Hsc70, Hsp60, or Hsp32. The induction of Hsp70 was blocked by quercetin. Immunohistochemistry showed that Hsp70 was localized mainly in the tubular epithelial cells. Preconditioning rats with GGA significantly decreased BUN and serum creatinine levels after I/R injury. Histologic examination revealed that GGA significantly attenuated tubular damage and macrophage infiltration. The number of TUNEL-positive cells also decreased significantly in the GGA group.

    BACKGROUND: Caveolin is a principal component of caveolae and regulates signaling in caveolae. Mesangial cells contain many caveolae, and thus manipulation of caveolin-1 expression level might be useful to control mesangial cell proliferation, which is an important aggravating factor in many renal diseases. METHODS: In the present study, we transfected caveolin-1 cDNA to rat primary mesangial cells and MES13 cells, and examined the effects on Raf-extracellular signal-regulated protein kinase (ERK) kinase (MEK)-mitogen-activated protein (MAP) kinase pathway and cell proliferation stimulated by basic fibroblast growth factor (bFGF) and platelet-derived growth factor (PDGF). Activity of the kinases was analyzed by immunofluorescence labeling and Western blot analysis. RESULTS: The overexpression of caveolin-1 inhibited the activation of Raf-1, MEK-1/2, and MAP kinase induced by either bFGF or PDGF. Furthermore, it suppressed the cell proliferation caused by the cytokines. The effect was specific to the Raf-MEK-MAP kinase pathway, because it did not influence activation of Smad2 induced by transforming growth factor-beta (TGF-beta). On the contrary, expression of a dominant-negative caveolin mutant, DGV-caveolin, augmented activation of MAP kinase. CONCLUSION: The result showed that overexpression of caveolin-1 in mesangial cells suppresses MAP kinase activation and cell proliferation induced by bFGF and PDGF. Because bFGF and PDGF are two major cytokines involved in the mesangioproliferative nephritis, the result implies that introduction of caveolin-1 expression vector is a potential therapeutic tool for the disease.

    BACKGROUND: The presence of Galalpha1-3Galbeta1-4GlcNAc (alphaGal) in pigs is a formidable barrier for pig-to-primate xenotransplantation. We have reported that administration of recombinant endo-beta-galactosidase C (EndoGalC) removes alphaGal on porcine erythrocytes and kidneys. The present study examined the effects of EndoGalC gene therapy on alphaGal suppression. METHODS: Naked plasmid DNA encoding Igkappa-EndoGalC was given to rats by rapid tail vein injection. The expression of alphaGal in the heart and kidney were studied by lectin staining followed by computer-assisted quantitative analyses. alphaGal expression on erythrocytes was determined by flow cytometric analyses. Enzymatic activity of EndoGalC in the serum was also determined by evaluating the capacity of EndoGalC in removing alphaGal epitopes. Elimination of alphaGal was further studied by injecting antibodies against alphaGal to rats 2 days after the gene transfer. RESULTS: Administration of 1 mg of Igkappa-EndoGalC/pCAGGS plasmid eliminated alphaGal from the vascular endothelium of the heart and kidney on day 1 and day 2. Between days 4 and 7, alphaGal started to reappear, but remained suppressed. No serious adverse effect was observed in rats treated with EndoGalC. Flow cytometric analyses showed that EndoGalC digested 97% of alphaGal on erythrocytes when measured 4 days after the gene transfer. Enzymatic activity of EndoGalC in the serum peaked on day 1, and significant levels were still observed on day 7. When antibodies against alphaGal were given, rats treated with EndoGalC showed no change, while all control rats died within 40 min. CONCLUSIONS: The present study demonstrates the potential of an EndoGalC gene transfer, using a hydrodynamics-based delivery system, in eliminating alphaGal from endothelial cells in vivo. The results also ensured that EndoGalC is not harmful suggesting that the production of pigs overexpressing EndoGalC would be a reasonable alternative to pigs deficient in alph

    Acute peritonitis, in which peritoneal mesothelial cells are directly exposed to bacterial components, is a major cause of peritoneal dysfunction in continuous ambulatory peritoneal dialysis patients. We have previously shown that Toll-like receptors (TLR) are expressed in kidney cells, and LPS induces TLR4-dependent chemokine production in tubular epithelial cells. The present work was designed to investigate the involvement of TLR, especially TLR4, in the lipid A-mediated chemokine production by murine peritoneal mesothelial cells (MPMC). A primary cell culture of MPMC from C3H/HeN mice (wild-type mice; LPS sensitive) and from C3H/HeJ mice (containing a point mutation of TLR4; LPS hyposensitive) was established. The expression profile of the TLR family and their accessory molecules, CD14 and MD-2, which are requisite for the LPS signaling pathway, was examined by RT-PCR, Northern blot test, and immunohistochemical staining. Synthetic lipid A-mediated chemokine production by MPMC was studied. The involvement of MAP kinase family (ERK, JNK, and p38 mitogen-activated protein kinase) and nuclear factor (NF)-kappaB in these processes was also studied. MPMC constitutively express TLR4, CD14, and MD-2. A prominent induction of monocyte chemotactic protein-1 (MCP-1) and macrophage inflammatory protein (MIP)-2 by MPMC was detected after lipid A stimulation and was strictly dependent on TLR4. Furthermore, TLR4-dependent chemokine production followed by leukocyte influx into the peritoneal cavity was also confirmed in vivo after stimulation with LPS. mRNA expression of MCP-1 was abolished by NF-kappaB inhibition, but were not affected by the inhibition of ERK, JNK, or p38. As compared with MCP-1, MIP-2 mRNA expression was inhibited by a high dose of curcumin but not by NF-kappaB decoy oligodeoxynucleotide and individual inhibitions of MAP kinase, suggesting that the additional signaling pathway with NF-kappaB might be involved in mRNA expression of MIP-2. These show that TLR

    BACKGROUND: Although Aristolochia manshuriensis (AM), which was incriminated in the Japanese variety of Chinese herbs nephropathy, has been recently shown to be nephrotoxic in rats, less is known about whether this toxicity is attributable to its aristolochic acids (AA). We compared the renal effect of AM with that of Akebia quinata (AQ), which has similar components to AM but is free of AA; we also compared this effect of AM with that of pure AA, and studied its possible mechanism. METHODS: In study 1, rats were divided into four groups. Each group was orally given either 0.4 g of AM, 4 g of AM, or 4 g of AQ per day, or vehicle, for 5 days. In study 2, rats were given 4 g of AM (which contained 4 mg of AA), or 4 mg of pure AA per day, or vehicle, for 5 days. Renal function, and renal histology were evaluated on day 5 in study 1 and on days 1, 3, 5, and 14 in study 2. In study 2, terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end-labeling (TUNEL) and proliferating cell nuclear antigen (PCNA) staining were also performed. In study 3, rats were treated in the same way as in study 2, but were all killed on day 5. Concentrations of AA (I + II) were measured in serum and urine in study 2, and in the kidney, lung, heart, liver, and spleen in study 3. RESULTS: In study 1, only the rats that received 4 g/day of AM developed tubular necrosis, azotemia, proteinuria, and glucosuria. In study 2, both AM- and AA-treated rats showed progressive tubular damage, decreased renal function, and increased urinary protein excretion. The degree of these alterations was comparable in the AM and AA groups. Moreover, the concentrations of AA (I + II), in serum, urine, and kidney were also comparable in the AM- and AA-treated rats. High levels of AA were detected in the lung and kidney. Apoptotic tubular cells increased on day 5 and had decreased by day 14 after the withdrawal of AM or AA. Meanwhile, proliferating tubular cells progressively increased from day 3 to day 14. C

    It has been postulated that protein filtered through glomeruli activates tubular epithelial cells, which secrete vasoactive and inflammatory substances including chemokines, leading to tubulointerstitial renal injury. The present study was designed to investigate the role of monocyte chemoattractant protein-1 (MCP-1) in this process and to evaluate the effectiveness of a kidney-targeted gene transfer technique using hydrodynamic pressure. Naked plasmid encoding 7ND (an MCP-1 antagonist) or a control plasmid was introduced into the left kidney of rats. Three days after gene transfer (day 0), intraperitoneal administration of bovine serum albumin (10 mg/g body wt per day) was started and continued for 14 or 21 d. RT-PCR showed that 7ND mRNA was expressed only in the gene-transfected kidney. Immunostaining showed that 7ND protein was localized in the interstitial cells. Macrophage infiltration was significantly reduced in the left kidney of rats treated with 7ND on days 14 and 21. In the right kidney, such effects were not observed. 7ND also attenuated tubular damage and decreased the number of apoptotic cells. Computer-assisted analysis revealed that the areas positively stained for alpha-smooth muscle actin (alpha SMA), fibronectin-EDA, type I collagen, and collagen fibrils were significantly reduced in the 7ND-treated kidney on day 21. Furthermore, 7ND gene therapy significantly reduced MCP-1 and TGF-beta 1 mRNA expression. These results demonstrate that MCP-1 plays an important role in the development of tubulointerstitial inflammation, tubular damage, and fibrosis induced by proteinuria. The fact that 7ND gene therapy had little effect on the contralateral kidney indicates that 7ND acted locally. This strategy may have a potential usefulness as a gene therapy against tubulointerstitial renal injury.

    BACKGROUND: Lack of nocturnal blood pressure (BP) fall (non-dipping) is common among haemodialysis (HD) patients, but much less is known regarding its association with cardiovascular (CV) disease morbidity and mortality. METHODS: Eighty HD patients initially underwent 24 h ambulatory BP monitoring (ABPM), and then they were defined as either 'dippers' (n=24, nocturnal BP fall > or = 10%) or 'non-dippers' (n=56, fall <10%). Coronary angiography was performed in the patients who had signs and/or symptoms of coronary artery disease (CAD). Twenty-four hour ambulatory ECG was recorded in 20 dippers and 20 non-dipper HD patients, and in 20 normal subjects. All patients were followed for up to 5.8 years (33.0+/-19.1 months). The outcome events studied were the hospitalisations due to CV diseases and CV death. RESULTS: Compared with dippers, non-dippers initially had a higher incidence of coronary artery stenosis (P<0.05) along with left ventricular asynergy (both Ps<0.01). The circadian rhythm of autonomic function was impaired in non-dippers. The incidences of CV events and CV deaths were 3.5 and 9 times higher in non-dippers than in dippers. The cumulative CV event-free survival and CV survival rates were lower in non-dippers than in dippers (P=0.02 and P=0.005, respectively). Based on Cox analysis, non-dipping was associated positively with CV events and CV mortality [hazard ratio (HR) 2.46, 95% CI 1.02-5.92, P=0.038 and HR 9.62, 95% CI 1.23-75.42, P=0.031, respectively]. Meanwhile, nocturnal systolic BP fall, diurnal systolic BP and diurnal pulse pressure were negatively associated with CV event/death. The clinic BP was not associated with CV event/death. CONCLUSIONS: The non-dipping phenomenon is closely related to a high incidence of CV diseases, a poor long-term survival and profound autonomic dysfunction. ABPM is useful in predicting long-term CV prognosis in HD patients.

    BACKGROUND: Interstitial infiltration of macrophages (M&oslash;) is one of the main causal factors for the tubulointerstitial injury. However, precise mechanisms of M&oslash; infiltration into tubulointerstitium have not been fully explored. The purposes of this study were to assess the role of selectins in the acute infiltration of M&oslash; in rats with unilateral ureteral obstruction (UUO) and to evaluate the role of vasa recta, that is, whether they facilitate massive influx of M&oslash; into the interstitium by functioning as specialized vessels. METHODS: To evaluate the role of selectins in M&oslash; infiltration into tubulointerstitium, the expression of selectins and L-selectin ligands was examined by immunohistochemistry and immunoelectron microscopy. The functional role of P-selectin in vasa recta was studied by Stamper-Woodruff assay, in vivo p-M&oslash; migration assay and in vivo blocking experiments with the monoclonal antibody (mAb) ARP2-4. RESULTS: Selective expression of P-selectin was detected in vasa recta as early as one hour after UUO, and the expression increased thereafter for 96 hours. In contrast, endothelial expression of L-selectin ligands and E-selectin were not detectable. In the Stamper-Woodruff assay on kidney sections of rats with UUO, the adhesion of isolated rat peritoneal M&oslash; (p-M&oslash;) to vasa recta was significantly inhibited by the mAb ARP2-4 (P-selectin blocker; P < 0.01), but not by mAb ARE-5 (E-selectin blocker) or rLECIg (rat L-selectin chimeric protein). In the in vivo transfer experiments with fluorescein-labeled p-M&oslash; into rats 48 hours after UUO, labeled p-M&oslash; had accumulated around vasa recta at three minutes and had infiltrated predominantly into the outer medulla at 180 minutes. The number of labeled p-M&oslash; was reduced when the rats were pretreated with ARP2-4 (P < 0.01). Finally, ARP2-4 (10 mg/kg), injected 15 minutes before UUO, reduced the number of infiltrated M&oslash; (P < 0.01). CONCLU

    BACKGROUND: Coagulation and inflammation are both important processes that contribute to glomerular injury. The present study was performed to evaluate the effects of recombinant human soluble thrombomodulin (RHS-TM) in a lethal model of thrombotic glomerulonephritis and to investigate the possible mechanisms. METHODS: Thrombotic glomerulonephritis was induced in rats by administration of lipopolysaccharide and rabbit anti-rat glomerular basement membrane antibody. One hour later, RHS-TM or heparin was administered, and the histological findings, renal functions, and coagulation parameters were evaluated. To evaluate the contribution of carboxypeptidase R (CPR) to the results obtained in rats treated with RHS-TM, plasma CPR levels were measured. Then, carboxypeptidase inhibitor (CPI), which prevents the function of CPR, was administered. RESULTS: Massive glomerular thrombosis and lung hemorrhage developed within five hours of disease induction, and all rats died within 24 hours. RHS-TM (3 mg/kg) prevented the progression of the disease and all rats survived. Heparin (250 U/kg/h) showed similar anti-thrombotic effect, but induced massive hemorrhage in the lungs or stomach. RHS-TM attenuated leukocyte/neutrophil infiltration in the glomerulus but heparin did not, suggesting that RHS-TM has anti-inflammatory properties. CPR levels in plasma were about threefold higher in rats treated with RHS-TM compared to those in rats treated with heparin. Furthermore, the inhibitory effect of RHS-TM on leukocyte/neutrophil infiltration was significantly diminished by injection of CPI. CONCLUSION: RHS-TM effectively attenuates the injuries of thrombotic glomerulonephritis in rats. The results indicate that RHS-TM, in addition to its anti-thrombotic action, may exert its anti-inflammatory properties by converting proCPR to CPR, which then inactivates anaphylatoxins. RHS-TM is a potential novel therapeutic tool for thrombotic glomerular injury and related disorders.

    Bowman's capsular and tubular basement membrane (TBM) deposits are an extremely unusual finding in non-lupus membranous glomerulopathy (MGN). We report three atypical cases of MGN with abundant Bowman's capsular and TBM deposits. In two cases, MGN was idiopathic; in the third case, MGN occurred in the renal allograft in the setting of HCV seropositivity. In addition to the usual glomerular capillary wall deposits, immunofluorescence and electron microscopy revealed extensive immune deposits within Bowman's capsule and TBMs, predominantly at the base of parietal and tubular epithelial cells. These cases suggest a potential pathomechanism of autoantibody to secreted epithelial antigens shared by visceral, parietal, and tubular epithelial cells. In all three cases, indirect immunofluorescence was unable to detect autoantibody to normal renal epithelial or matrix constituents. Furthermore, ELISA was unable to demonstrate circulating antibody to major extracellular matrix components. The implications of these findings for the pathogenesis of MGN are explored.

    BACKGROUND: Platelet-activating factor (PAF) is a phospholipid mediator of inflammation which has been implicated in rejection. The interaction of anti-alpha-galactosyl natural antibodies (anti-alpha gal Abs) with endothelial cells is the initial step for the development of xenograft rejection. In our study, we stimulated porcine aortic endothelial cells (PAEC) with anti-alpha gal IgG to investigate the synthesis of PAF from PAEC and its biological consequences. METHODS AND RESULTS: PAF was extracted and chromatographically purified from cultured PAEC stimulated with baboon anti-alpha gal Abs. The Abs induced a dose-dependent synthesis of PAF peaking after 30 min of incubation, and decreasing thereafter. Concomitant cell shape change, motility, and cytoskeleton redistribution were observed. These events were prevented by addition of a panel of PAF-receptor antagonists. An SV40 T-large antigen-immortalized PAEC line was engineered to express PAF acetyl-hydrolase (PAF-AH) cDNA, the major PAF-inactivating enzyme. These transfected cells exposed to anti-alpha gal Abs showed reduced cell contraction and motility compared with empty vector-transfected cells. Moreover, in PAEC stimulated with anti-alpha gal Abs, the synthesis of PAF promoted the adhesion of a monocytic cell line as shown by the inhibitory effect of PAF-receptor antagonists and of PAF-AH expression. Finally, studies on cell monolayer demonstrated an enhanced permeability 48 hr after exposure to anti-alpha gal Abs, and this increase was prevented by PAF-inactivation and by PAF-receptor blockade. CONCLUSIONS: These results demonstrate that on stimulation with anti-alpha gal Abs, PAEC synthetize PAF which can contribute to several vascular events involved in xenograft rejection.

    BACKGROUND: The pig is the donor animal of choice for human xenotransplantation. In the most relevant pig-to-baboon model, pig organs transplanted into baboons are hyperacutely rejected by natural xenoantibodies, which mainly bind to alpha-galactosyl (alphaGal) epitopes expressed at the surface of endothelial cells. Recent advances in controlling hyperacute rejection have led to improved survival of these xenografts, and it is now important to identify alphaGal binding sites in other cells and tissues that may be subject to immunologic attack. To this end, we have studied whether alphaGal antibodies bind to glycated proteins of the extracellular matrix in the kidney and other organs most likely to be used for human xenotransplantation. METHODS: High-titer anti-alphaGal antibodies, similar to human natural xenoantibodies, were prepared in baboons, and their reactivity with components of pig extracellular matrix was tested by serology and immunohistology. RESULTS: The antibodies recognized epitopes of immobilized murine, bovine or porcine thyroglobulin, laminin, heparan sulfate proteoglycans, and fibronectin. In sections of pig tissue, the antibodies bound to endothelial and certain epithelial cells, as shown in previous studies, and also to mesenchymal cells, basement membranes, and extracellular matrices, in which they colocalized with matrix glycoproteins, especially laminin and heparan sulfate proteoglycans. CONCLUSIONS: These results suggest that when pig xenografts can be made to survive for prolonged periods, the reactivity of alphaGal antibody with matrix molecules can induce basement membrane and matrix lesions similar to those induced in laboratory animals by antilaminin and antiheparan sulfate proteoglycans antibodies.

    BACKGROUND: Expression of the alpha-gal epitope in mice can be completely eliminated by disruption of the alpha1,3 galactosyltransferase gene. As an initial step for assessing the feasibility of this approach in the pig, it was of interest to compare the expression of alpha-gal epitopes in pig and mouse organs. METHODS: Membranes from pig and mouse organ homogenates were analyzed for alpha-gal epitope expression by Western blots, enzyme-linked immunosorbent assay (ELISA), immunostaining of tissues, and ELISA inhibition assay. RESULTS: Immunostaining of Western blots with human anti-Gal detected alpha-gal epitopes on glycoproteins from pig organs but not on glycoproteins from the corresponding mouse organs. ELISA with membrane homogenates and immunostaining of tissue sections demonstrated a much higher binding of human anti-Gal to alpha-gal epitopes on pig membranes than on mouse membranes. ELISA inhibition assay with monoclonal anti-Gal indicated that alpha-gal epitope expression in pig organs is up to 500-fold higher than in mouse organs. CONCLUSION: Expression of alpha-gal epitopes in pig organs is many fold higher than in mouse organs. The abundance of these epitopes in pigs raises the question of whether pigs can properly develop without expression of alpha-gal epitopes.

    As barriers to xenotransplantation are surmounted, such as suppression of hyperacute rejection allowing improved graft survival, it becomes important to define longer-term host-xenograft interactions. To this end we have prepared in baboons high titer anti-alpha-Galactosyl (alphaGal) and anti-porcine aortic endothelial cell antibodies, similar to human natural xenoantibodies and reactive with epitopes of thyroglobulin, laminin, and heparan sulfate proteoglycans. When injected into pigs with a protocol similar to that used in the rat to show the nephritogenic potential of heterologous anti-laminin and anti-heparan sulfate proteoglycan antibodies, baboon immunoglobulins bound first to renal vascular endothelium, and later to interstitial cells, especially fibroblasts and macrophages, and to antigens in basement membranes and extracellular matrix, where they colocalized with laminin- and heparan sulfate proteoglycan-antibodies, and with bound Griffonia simplicifolia B4. A similar binding was observed in other organs. The pigs did not develop an acute complement-dependent inflammation, but rather chronic lesions of the basement membranes and the extracellular matrix. Incubation of renal fibroblasts with baboon anti-alpha-Galactosyl antibodies resulted in increased synthesis of transforming growth factor-beta and collagen, suggesting a possible basis for the fibrotic response. The results demonstrate that in this experimental model a consequence of alphaGal antibody interaction with porcine tissues, is immunoreactivity with alphaGal on matrix molecules and interstitial cells, priming mechanisms leading to fibrosis resembling that in chronic allograft rejection. The possibility that similar lesions may develop in long-surviving pig xenografts is discussed.

    The interaction of antibodies with cell surface antigens may induce redistribution of immune complexes, followed by antigen depletion, with increased resistance to injurious effect of antibody and complement (antigenic modulation). Human natural antibodies to Gal alpha 1,3Gal beta 1,4GlcNAc-R (alpha Gal) epitopes expressed at the surface of pig cells are a major obstacle to xenotransplantation. Recent studies have shown that these antibodies do not modulate alpha Gal, but the morphological consequences of the antigen-antibody interaction are unknown. Pig blood and endothelial cells, were exposed to baboon alpha-Gal antibodies, and studied by immunofluorescence and phase contrast microscopy, flow cytometry, and inhibition enzyme-linked immunosorbent assay. In cells studied at 4 degrees C or fixed, alpha Gal was diffusely expressed at the surface. After cross-linking at 37 degrees C, antigenic modulation did not occur, but granular redistribution of alpha Gal immune complexes was seen in all cell types. In other systems a similar redistribution is known to induce perturbation of the plasma membrane/cytoskeletal structure with changes in adhesive properties, gene regulation, and T cell activation, which could be important if pig xenografts will be made to survive for prolonged periods.

    The present work was designed to elucidate the in vivo role of complement in the proteinuria-associated tubulointerstitial injury. Rats were intravenously injected with puromycin aminonucleoside, and massive proteinuria was observed within 5 days. Prominent tubulointerstitial injury characterized by proximal tubular degeneration, tubular dilatation, and leukocyte infiltration were observed 7 days after injection. C3 and C5b-9 were observed in the luminal side of proximal tubular cells. Renal function, assessed by inulin and para-aminohippurate clearance, was significantly decreased. To-assess the role of complement in this model, rats were injected with either cobra venom factor or soluble recombinant human complement receptor type 1 starting at day 3. These manipulations significantly improved tubulointerstitial pathology and para-aminohippurate clearance without affecting the degree of proteinuria. Deposition of C3 and C5b-9 was not detected in the kidney of rats depleted of complement by cobra venom factor. In rats treated with soluble complement receptor, C3 was still detected in the tubules, but deposition of C5b-9 was not observed. Soluble complement receptor was detected at the site of C3 deposition and in the urine. These data strongly suggest that complement plays a pivotal role in proteinuria-associated tubulointerstitial injury and that systemic complement depletion or inhibition of complement in the tubular lumen may diminish the tubulointerstitial damage.

    Using transfection of NIH 3T3 cells, we have recently demonstrated that multiple endocrine neoplasia (MEN) 2A mutations activate the c-Ret protein by inducing its disulfide-linked homodimerization on the cell surface. To investigate whether the homodimers are present in original tumors, the expression of the c-Ret protein was analyzed in eight sporadic and two MEN 2A-associated pheochromocytomas, the latter two of which contained mutations in cysteine 618 or 634 of Ret. The c-Ret protein was expressed at variable levels in all pheochromocytomas examined. By labeling the c-Ret protein immunoprecipitated from tumor tissues with [gamma-32P]ATP in vitro, its homodimers were detected in pheochromocytomas from MEN 2A patients but not in a sporadic tumor. This result represents the first demonstration of Ret homodimers in original tumors.

    We investigated mutations of the ret proto-oncogene in Japanese patients with multiple endocrine neoplasia (MEN) type 2A and type 2B. DNAs from pheochromocytomas and/or medullary thyroid carcinomas (MTCs) of five MEN 2A and three MEN 2B patients were amplified by a polymerase chain reaction (PCR) and analyzed. Tumors of four MEN 2A patients had missense mutations in Cys 634 in the extracellular domain of the ret proto-oncogene. The same mutations were detected in normal tissues of the patients, indicating that the mutations had arisen in the germ line. Using a reverse transcriptase(RT)-PCR, both normal and mutant transcripts of the ret proto-oncogene were detected in a tumor of one patient with MEN 2A mutation. In addition, three MEN 2B patients examined had the same point mutation (ATG-->ACG) at codon 918 in the tyrosine kinase domain of the ret proto-oncogene. Since all mutations identified in this study generated new restriction enzyme sites or eliminated a restriction site, the mutant alleles of affected family members could be readily detected without sequencing.

    aHUSは血液中ではなく、血管内皮細胞膜上での無秩序な補体活性化が問題であり、単純な採血で評価できないところに検査開発の難しさがある。我々は、2020年より開始したaHUS全国調査研究で登録のあった症例の血漿から、細胞外小胞(Exosomes)を精製し、Exosomes上の補体関連タンパクを測定し、細胞膜上の補体活性を評価する。またex vivoでaHUS患者の血漿と血管内皮細胞株との反応系にエクリズマブを添加することにより、実際に薬剤を投与する前に、治療反応性を見極める。
    我々は、非典型溶血性尿毒症症候群(aHUS)の疾患事務局を、2020年より東京大学から引き継ぎ、医療施設からの症例相談を受けるとともに、奈良県立医科大学にて開発されたヒツジ赤血球溶血試験(補体機能検査)を行ったり、抗H因子抗体(抗CFH抗体)価を測定するなどして研究、臨床の両面から知見を蓄積してきた。2020年度は62症例の臨床相談を受け、91検体の解析を行った。2021年度は65症例の臨床相談を受け、81検体の解析を行った。そして本研究を開始した2022年度は1月までに66症例の相談、77検体の解析を行った。
    当方で33例のaHUSの診断に至り、内補体関連遺伝子の病的バリアント保有例は19症例、バリアント未検出は10症例、未検査4症例であった。病的バリアント保有割合は65%(19/29)という数字は、過去の報告と同等~やや高めの値で、概ね妥当な数値と考えられる。
    19症例のバリアントの内訳は、CFH:7例、C3:9例、CD46:3例、CFI:1例(1例のC3, CD46重複例を含む)であった。世界的にはCFHの病的バリアント保有例の割合が高いが、本邦ではC3、特にC3 I1157Tバリアントの割合が高いことは、既に報告(Clin Exp Nephrol . 2018 Oct;22(5):1088-1099.)があり、同じ傾向であった。
    上記の様に、疾患の概要、特に本邦における特徴が明らかになっている。課題の1つであるヒツジ赤血球溶血試験に関しては、CFH病的バリアント保有例の7例の内、6例で測定が行われ5例で陽性と診断され、遺伝学的検査の前にaHUSへの診断につなげることが出来た。一方で他の遺伝子バリアントでは、C3 I1157Tバリアントの1例で陽性になったのみで、他のバリアントでは陰性となり、aHUSの早期診断には繋がらず、課題の残る結果であった。
    aHUSは希少疾患であり、本研究(非典型溶血性尿毒症症候群(aHUS)全国調査研究)は、現在日本で行われているaHUSの最大のコホート研究であると言える。上述のように33症例の診断に寄与してきた実績があり、本年度の症例数も例年と同じ水準~やや多めの数を記録している。aHUSのみならず他のTMA(STEC-HUS, TTP, 二次性TMA)の症例も含まれていることが、本コホート研究の強みである。つまり、aHUSの診断に寄与する検査方法を、他のTMAを引き起こす疾患と比較することができる。
    現状では血漿中のC5b-9は、エクリズマブ治療を行うと完全に抑制されるが、血漿交換を数回行った状況では、そこまで抑えられていないことがわかっている。また興味深いことに未発症者の検体でもC5b-9は基準値を上回っており、あきらかなTMAによる臓器症状がない状況においても異常値を取っていることの意義は、今後検証をしていく必要があるものと思われる。また、aHUS以外のTMAであるTTPにおいても血漿C5b-9が異常高値であったことは、C5b-9の診断的価値の検討に置いて大切な結果である。つまり補体が一義的に関与するaHUSのみならず、別要因で血管内皮細胞障害を引き起こす疾患でも、二次的に補体の活性化が起きている可能性は示唆される。これら問題点に置いて、更に症例数を重ねて検証を続けていく。
    基本的には現在のaHUS疾患事務局を通した症例の解析を続けていく。名古屋大学医学部腎臓内科学のホームページにおいて事務局の案内をするとともに、動画などの説明資材を用いて疾患の啓蒙を続ける。
    目的の検査に関しては、ある程度の数のaHUS症例、及び、STEC-HUS, TTP,
    二次性TMAの症例が蓄積した時点で、更にエクソソームの抽出を行う。またin vitroにおけるエクリズマブ抑制試験は、ヒツジ赤血球溶血試験においては既に数多く行っている。フローサイトメトリーによる解析を通して、生体内における補体活性化の量的解析、つまり定量性をもたせることによって、実臨床に置いて発症、再発診断、治療効果判定、のみならず抗C5抗体薬(エクリズマブ、ラブリズマブ)投与前に治療効果予測を行えるようになることは、医療資源の適切な利用に関わる問題として非常に重要な知見となると考える。

    慢性腎臓病(CKD)患者の表現系は老化に見られる諸変化に酷似している。通常の維持血液透析患者(従来透析)と長時間透析患者、保存期腎不全患者は、尿毒症にさらされている強度や条件が異なる。尿毒症存在下において、どのような外的・内的環境負荷(Allostatic load)が免疫学的変調と慢性炎症をきたし、Microbiomeの変調をきたすのか、老化の指標となる遺伝子保護の不調(テロメア消耗)に関与しているか解析し、実際の心疾患、感染症、死亡率と比較することにより、腸内細菌叢の改善をターゲットとしたCKD患者の新規治療戦略の構築を目指すものである。
    最も深刻な尿毒症下にある従来透析療法施行中(NICE-GENEコホート研究)の患者、長時間透析により尿毒症を可及的に管理している患者(RRTRコホート研究)、保存期腎不全患者(N-KDRG)のサンプルの取集を予定通り遂行している。登録状況は順調である。NICE-GENEコホート研究では現在までに約300名の登録、RRTRコホート研究では約200名の登録(全体で約300名登録のうち長時間透析200名)、N-KDRGでは約100名の登録が達成されている。環境因子(allostatic load)の情報収集については、患者背景・臨床情報(腎機能、炎症、栄養状態、心不全、および動脈硬化指標等)に加えて、老化の表現系であるフレイルの評価項目に基づき、体組成分析・身体機能・身体活動量・精神状態に関するデータ収集を開始した。今後、社会因子としての経済指標や医療リテラシーに関する指標、介護度なども収集可能か検討している。
    循環白血球に取り込まれた細菌由来のDNA断片の解析については、NICE-GENEコホート研究における腸内細菌叢の変調の予備解析から、尿毒症などから惹起される酸性環境により炎症性の負担が増加することが一因で起こる腸内細菌叢の変調ではないかと推察した。 さらに、過去の報告と比較検討しこの腸内細菌叢の変調に推測される状況について、我々のコホートでの事例と合致するか検討を進める方針である。
    また、コントロールの検体収集として、おそらく約100名程度のサンプルが収集できる見込みである。
    国際共同研究施設であるカロリンスカ研究所、グラスゴー大学とは、COVID19パンデミック下、著しく交流が疎になっていたが、今後、国際学会などの機会を通じて情報交換を行い、循環白血球内のMicrobiomeの変調についてさらなる詳細な解析を行えるよう検討を継続していく。
    すでに開始してるコホート研究の患者登録については順調であるものの、循環白血球に取り込まれた細菌由来のDNA断片の解析については、すでに我々が予備解析に使用した健常人サンプルが、腎臓病患者サンプルと年齢構成があまりに異なり、検体数も少数であったため、比較検討がむずかしいことがわかった。そのため、新たに同年代の日本健常人の対照者によるサンプルの収集を開始している。
    腸内細菌叢の変調と細胞老年マーカーについて、テロメア長との検討を予定していた。しかしながら、共同研究者グラスゴー大学のProf. Paul Shielsより、我々が今まで行ってきたテロメア測定法によるテロメア長の解析よりCDKN2Aの評価のほうが、細胞老化を検討するにはSensitiveではないかとの指摘をいただき、予算やサンプルのクオリティも含めて実施可能か検討している。
    NICE-GENEコホート研究、RRTRコホート研究、N-KDRG研究いずれも、患者登録、サンプル収集、臨床情報収集を継続する。慢性腎臓病の初期の患者、さらに慢性腎臓病をきたしうる危険因子を持つ患者についても検討できると、慢性腎臓病の発症、進展、末期腎不全となってからの合併症にいたるまで、患者生涯をカバーするserialな経過を追うことができる。これが可能であれば、慢性腎臓病患者の老化を解明する当研究において研究目的を解明するために有用であると考えられる。
    また、循環白血球に取り込まれた細菌由来のDNA断片の解析については、細菌叢の変調は予想より多彩であった。細菌叢の変調の解釈についてすでに確立されたものが少なく、患者の表現系にどのように影響しているかについて報告するのに注意が必要であり、過去報告や共同研究機関でのデータとも比較し検討を続けていく。
    海外の研究者の興味は、日本人の慢性腎臓病患者の生存を含めた治療成績が欧米に比し良好であることが、日本食に起因しているのではないかというClinical Questionに基づいており、可能であれば食事に関する(とくに日本独特の発酵食品や魚介類の摂取)について追加情報を取得できないか検討していく方針である。

    間葉系幹細胞(MSC)は様々な疾患に対する治療効果が示されている。しかし、MSCは品質のばらつきがあるため、治療効果の担保が大きな問題となっている。本課題では、iPS細胞からMSCを分化誘導し、腎炎に対する治療効果が安定して高いことを確認し、MSCの欠点を克服する。さらに治療効果を高める操作を加え、これまでのMSCよりも、腎炎に対して各段に高い治療効果を得る。最終的には、既存の治療法を凌駕する、難治性腎疾患に対する全く新しい細胞治療を確立する。

    既存の免疫抑制薬は過剰免疫抑制による感染症などの副作用が問題となっている。間葉系幹細胞(MSC)は、障害部位の炎症強度に応じた自律的かつ局所での炎症制御が可能なことから、次世代の免疫制御療法として期待されている。しかし、その作用機序は十分解明されておらず、その実用化に際しては課題が多い。新概念として『障害部位に到達したMSC由来細胞外小胞が炎症細胞から放出される炎症性物質と微小空間で会合した時にのみ免疫抑制物質が生成されて局所での抗炎症作用が出現する』という着想に至った。本研究では、この新概念を検証して、効果的で安全な次世代型免疫・炎症制御療法の開発に取り組む。

    成人の一次性ネフローゼ症候群の主要な原疾患である一次性膜性腎症の診療では、近年、責任抗原に対する自己抗体を指標にした新しい診療技術が開発され、血液検査で鑑別診断および免疫的病勢評価が可能になりました。しかし、日本人の一次性膜性腎症患者の45%は責任抗原が未だ不明なため、自己抗体を指標にした新しい医療技術を受けられずにいます。
    そこで、本研究では、日本人一次性膜性腎症患者の未知の責任抗原を一つでも多く解明して、最終的には、日本人の一次性膜性腎症患者の大半で自己抗体を指標にした新しい診療技術が実現することを目差します。

    ポドサイトの機能不全は慢性腎臓病の進展に中心的な役割を担う。我々は、カルシウム/カルモジュリン依存性キナーゼIV(CaMK4)の活性化が、①ループス腎炎におけるポドサイト障害の原因の一つであること、②細胞骨格の制御を介したポドサイト障害と免疫複合体沈着・半月体形成に関与する知見を得た。
    また、本研究では難治性腎疾患(進行性半月体形成性腎炎、治療抵抗性ネフローゼ症候群)への治療応用を見据え、①ポドサイト内のCaMK4シグナルを介した半月体形成・糸球体硬化の分子機構の解明、②CaMK4をターゲットとした半月体形成性腎炎・難治性ネフローゼ症候群のポドサイト特異的新規治療法の開発をめざす。
    カルシウム/カルモヂュリン依存性キナーゼ(CaMK)シグナルに対するポドサイト特異的治療の確立のため、難治性腎疾患の一つである、難治性ネフローゼ症候群におけるCaMKシグナルの解析を行った。難治性ネフローゼ症候群の一つである巣状分節性糸球体硬化症(FSGS)においては、一部でCaMK4がポドサイト上に発現上昇が認められたが、CaMK2に関しては糸球体内での発現が見られなかった。同じカルシウム/カルモジュリン誘導性のキナーゼであるのにも関わらず、両者に違いが見られたことから、上流のCaMKキナーゼ(CaMKK)に着目した。なぜなら、CaMKKは、CaMKの中でCaMK1と4の活性化に必須のキナーゼで、CaMK2の活性化には関与しないためである。CaMKKは2種類のアイソフォームを持つが、両者を阻害する低分子化合物を使用して、その役割を検討した。FSGSモデルマウスに阻害薬を投与し、尿蛋白の推移を検討した。CaMK4阻害を行った場合と同様の結果が予想されたが、CaMKKの阻害により、蛋白尿の誘導に関しては有意な差は認められなかった。長期の経過では、野生型はある時点でピークを迎え尿蛋白は改善傾向に転じるが、阻害薬投与群においては改善の遅延がみられ、有意に障害が遷延する結果となった。CaMKKはポドサイト障害の可逆性に関与している可能性があり、今後CaMKKの2種類のアイソフォームの役割の違いも含めて、各々の遺伝子欠損マウスを使用し検証していく予定である。
    CaMKファミリーの発現の違いにより上流のCaMKKの調節機構の解析を要した。当初CaMK4を活性化する役割をもつCaMKKは、同様にポドサイト障害を軽減すると想定されたが、予想に反し悪化傾向を呈した。予定していたCaMK4の機能解析のみならず、上流のCaMKKの解析も行う必要があるため、やや遅れる結果となっている。
    今後は、CaMKK-CaMK4経路の解析のため、CaMKKのアイソフォーム毎の機能解析を行う。そのための各欠損マウスは取得済みである。

    間葉系幹細胞(MSC)を用いた臨床試験はこの数年で著しく増加している。しかし、MSCを静脈内投与された患者が肺塞栓のため死亡した事例が報告されており、さらなる安全な幹細胞療法の開発が急務である。本研究では、MSCがもつ優れた成長因子・免疫制御因子の産生能力に着目し、細胞を直接体内に投与せず、これらの液性因子を体内に投与できる治療法としてMSC治療用中空糸膜カラムを開発する。これにより細胞による肺塞栓をゼロにできる。その際に、MSCの静脈内投与と遜色ない治療効果をカラムによって得るためには、MSCの活性化が必要であり、MSCを活性化する全く新しい細胞カラムを開発する。

    活性化好中球が放出するヒストンにより惹起される線溶系有意の致死性血栓症は,凝固系有意の敗血症由来のものとは異なる。この致死性血栓症の発症メカニズムの解明研究は,凝固系有意の致死性血栓症治療薬とは作用機序の異なる新規治療薬開発の重要な基盤研究となる。本研究では,これまでの研究成果を踏まえ,新たに血小板凝集および組織への接着,白血球-血小板複合体に関与する補体3型受容体との関わりの重要性に着目し,Mac-1欠損およびPILRα欠損マウスへヒストンを投与して致死性血栓症モデル動物を作製し,Mac-1がヒストン誘発性致死性血栓症に関与するかどうか,を解明する。
    補体3型受容体(Mac-1:CD11b/CD18)は、血小板凝集および組織への接着や白血球-血小板複合体の生成促進に関与することが知られている。我々は、ヒストン誘導性致死性血栓症モデルマウスにおいて、白血球におけるMac-1発現が亢進することを確認しているが、出血と血栓形成の双方が関与する同疾患にて、Mac-1がどのように発症へ関与するのか、詳細は不明であった。致死性血栓症におけるMac-1の関与を明らかにするため、C57BL6/J(野生型)マウスおよび同系統のMac-1欠損マウスへ細胞外ヒストンを投与し、致死性血栓症モデル動物の作製を行った。ヒストン投与後の生存期間、肺、肝・腎障害の程度,プロトロンビン時間(PT)、活性化部分トロンボプラスチン時間(APTT)を評価および測定した。Mac-1欠損マウスでは、野生型マウスに比して、ヒストン投与後の生存期間が延長し、組織障害についても、軽度であった。PT、APTTについてはMac-1欠損および野生型マウス間で差が認められなかった。上記結果を踏まえ、Leukoladherin-1(LA-1)を用い、Mac-1を一時的に活性化させることで、上記遺伝子改変マウスと比較して、ヒストンによる反応性が異なるかどうかを検討した。野生型マウスにLA-1(LA-1群)およびコントロールとしてDMSO(コントロール群)を前投与し、その後ヒストンを投与することで致死性血栓症を惹起させたところ、LA-1群およびコントロール群間でヒストン投与後の生存期間、臓器障害に差は認められなかった。
    2019年度の研究実施計画は、C57BL6/J(野生型)マウスおよび同系統のMac-1欠損マウスへ細胞外ヒストンを投与し、ヒストン投与後の生存期間、肺、肝・腎障害の程度、プロトロンビン時間(PT)、活性化部分トロンボプラスチン時間(APTT)を評価および測定することであった。上記研究を完了し、次年度前半に予定していたLeukoladherin-1(LA-1)投与実験も完了することができた。以上の結果を踏まえ、当初の計画以上に進展していると考える。
    Leukoladherin-1(LA-1)前投与による致死性血栓症への影響が認められなかった要因として、ヒストン自身のMac-1活性化作用が考えられる。そのため、LA-1とは異なる方法を用い、好中球の関与を検討する必要がある。次年度は抗Ly-6G抗体を用い、好中球をdepleteさせることにより、ヒストンによる致死性血栓症に与える影響を検討する。さらに、野生型およびMac-1欠損マウスの両個体から好中球を単離し、ヒストンがNETosisへ与える影響についても、検討する。

    血栓性微小血管症(TMA)は腎予後、生命予後ともに不良な難治性病態であるが、早期診断法や治療法は確立されていない。申請者らは腎障害モデルにおいて、補体活性化が腎障害を増悪させることを見出してきた。近年、Glycocalyxによる血管内皮の恒常性維持作用が注目されている。本研究では、「二次性TMAでは糸球体内皮細胞上のGlycocalyxの発現が低下し、それにより補体活性化が惹起され腎障害が増悪する」という仮説を検証する。本研究を通して、TMAの早期診断や治療標的の同定につながる新たな知見を見出すことを最終目標とする。
    近年、血栓性微小血管症(thrombotic microangiopathy : TMA)と診断される症例は増加傾向にありその原因も多様である。
    わが国のTMAの実態を調査するため、日本腎臓学会による腎生検レジストリー(J-RBR)のデータを活用した横断研究を実施した。2007年から2017年の10年間で38,495例の腎生検症例が登録されており、そのなかでTMAと診断された症例は152症例(0.39%)であった。TMAの基礎疾患としては、溶血性尿毒症症候群(HUS)/血栓性血小板減少性紫斑病(TTP) 16.4%, 膠原病 17.1% 薬剤性16.4 %が多い結果であった。このほかにも臓器移植関連、高血圧、妊娠、悪性腫瘍などTMAの原因は多彩であった。疫学的には小児から高齢者まで幅広くTMAを発症していた。小児はHUS/TTPが有意に多いが、成人期以降では二次性TMAの頻度が増加する傾向が認められた。小児・成人・高齢者の比較では、高齢者で有意に腎機能が低下しており、糖尿病や高血圧などによる潜在的な内皮障害がTMA病態を促進させて可能性が示唆された。この結果はClin Exp Nephrol. 2020 May 15. doi: 10.1007/s10157-020-01896-7にて報告した。二次性TMAのなかでも頻度の高い膠原病関連TMAに関しては、抗リン脂質抗体症候群(antiphospholipid syndrome : APS)に着目し、APSにおける腎障害を報告した (J Clin Rheumatol. 2019 Nov 8. doi: 10.1097/RHU.0000000000001173)。
    現在は強皮症に関連したTMA病態である強皮症腎クリーゼの予後と治療効果に関する臨床研究を実施している。二次性TMAにおける補体活性系および制御系の関与については検体収集中であり、集まり次第C5b-9などの因子を測定していく予定である。二次性TMAの動物モデルの作成は確立しておらず進歩状況としてはやや遅れている。抗悪性腫瘍薬関連TMAに関してはレジストリーに該当する症例が予想を下回っており遅れが生じている。
    全身性強皮症を中心とした膠原病に関連したTMA病態の予後改善のため、臨床予後調査と治療効果に関する臨床研究を進める。薬剤性TMAに関しては、抗悪性腫瘍薬関連TMA発症の実態調査のため症例のレジストリーを進めていく。二次性TMAの動物モデルの作成についてはさらなる検討が必要である。

    敗血症は、全世界的にみても死亡率が高い重篤な疾患である。また新たな治療法の開発は遅れ、生存率の改善は停滞している。我々はToll like receptorシグナルをmiRNAによって制御するといった、新しいアプローチによる治療を報告してきた。一方で幹細胞由来のエクソソームには、炎症性疾患における治療効果が報告されており、今回は低血清培地型脂肪由来幹細胞のエクソソームを用いて、我々が見つけ出したmiRNAを敗血症モデルマウスに投与して、治療効果の上乗せが可能かどうか、検証を行う。
    核酸医薬は、昨今開発が進む抗体医薬や細胞医薬に比して安価に安定的に生合成され、一度定めたプラットフォームを用いることによって、様々な疾患に応用可能な治療薬として注目を集めている。我々は、生体内に存在する自然のRNAi機構であるmicroRNA(miRNA)の治療的応用を目指し、過去においてPolyethylenimine (PEI)をドラッグデリバリーシステムとして用い、NF-κBを負に制御するmiR-146aを投与することで、敗血症モデルマウスの高サイトカイン血症を抑制し、生存率を高める事に成功してきた。
    一方細胞治療は、一部すでに実用化も進んでおり、様々な臨床的効果が期待されているが、核を含む細胞を体内に投与する事で、拒絶や癌化といったリスクが危惧されている。そこで細胞自身を投与するのではなく、細胞の放出する細胞外小胞、とくにエクソソームに着目し、エクソソームを投与することで細胞投与と同等の効果を認めたとする報告が多く見られるようになってきている。
    本研究は、当科で細胞治療研究として取り組んできた脂肪由来幹細胞(ASC)由来エクソソームを、それだけで投与するのではなく、治療効果をすでに確認しているmiRNAと組み合わせることで、治療の相乗効果を狙った新しい治療プラットホームの開発を目的としている。
    動物実験の解析により、投与したmiR-146a 発現プラスミドの作用点は脾臓であることが判明している。本年度においては、先行研究で用いたmiR-146a発現プラスミドは生体応用し難いため、成熟miRNAおよび人工核酸においても同等に脾臓がターゲットとして治療効果を得られるかを中心に検証すべく研究を行った。
    脾臓は二次リンパ節としては最大で、敗血症の発症において抗原提示、免疫の増幅、全身性へのサイトカイン産生の主たる臓器として役割を持っている。先行研究においてはmiR-146a発現プラスミドを用いており、発現に時間がかかるとともに生体の核内に遺伝子が導入されてしまうことになるため、一過性発現かつ即効性のある成熟miRNAを用いて、脾臓での取り込みを確認した。
    まず成熟miRNAを、PEIをドラッグデリバリーシステムとして脾臓への直接注射を行い、脾臓に投与後24時間をピークに48時間まで検出可能であることを確認した。脾臓に直接投与した場合、ごく一部合流した門脈を介して肝臓においても検出されたが、腎臓、肺には影響を及ぼさなかったため、他臓器への影響は限局的であることが示唆された。また同様に先行研究で明らかになったmiR-146aの脾臓マクロファージへの取り込みに関しても、F4/80による脾臓細胞のセレクションにより証明した。
    次に盲腸結紮穿孔モデルによりマウスに敗血症を起こし、同様にmiR-146aを投与した所、対照群(スクランブル配列)と比較して、Cr, BUN, AST, ALT, LDHを低下させることが可能であった。ただし、死亡率はmiR-146a投与群でむしろ悪化しており、治療により死亡を増やすが、生存した群においては治療効果を示すという結果となった。
    さらによりエクソソームに近いと考えられる、リポソームをドラッグデリバリーシステムとして用いた治療実験において、現時点で治療効果は確認できていない。
    マウス盲腸結紮穿孔モデルに置いて、miR-146a脾臓注射が治療効果を示す一方で死亡率を高めた理由の考察として、miR-146aが脾臓のマクロファージに取り込まれるところは確認されており、そのNF-κB抑制作用によりサイトカイン産生を抑制することから、(1)腹腔内の感染、菌血症に対する炎症の初期反応が抑制されてしまった可能性、(2)より晩期の免疫抑制によりsecondary infectionを引き起こした可能性の両面が考えられる。
    そもそも先行研究において効果が見られた原因としては、敗血症晩期の過剰な免疫反応としてのサイトカインストームを抑制するところにあり、感染成立初期の特に自然免疫の反応を抑制してしまった場合は最近の増殖を抑えきれず、そのまま死に至ると考えられるし、晩期の免疫力が正常に戻った後過剰な免疫抑制を起こした際は、二次感染で死亡する。つまり投与するタイミングが非常に重要であり、我々の先行研究においては、敗血症を起こす前に事前投与していたが、miR-146a発現プラスミドであったことから、効果の発現に時間がかかり、時期としてちょうど首尾よくサイトカインストームを抑制した可能性がある。
    臨床応用に関しては、事前投与は困難であることから、今後は(1)の可能性を考慮して、敗血症モデル作成直後に投与すするのではなく、数時間空けて投与することで反応を確認していく予定である。
    また、投与方法として脾臓直接注射は多臓器への影響が少なくより選択的に治療対象とする脾臓マクロファージに取り込まれるが、生体に与える侵襲も高い。よって今後は静注、腹腔内投与と言った別経路による治療を検討し、条件を確定していく予定である。

    また、バイオマーカー候補については異なる時期に採取されたバリデーション用検体を用いて、マーカーとしての感度・特異性の検討を実施した。7つの異なるネフローゼ疾患患者尿120検体を用いてバリデーション試験を実施した結果、独立した検体群においてもループス腎炎を他の6種のネフローゼから高精度に判別できることが証明された。
    また、検体の臨床情報との相関についても検討を実施した。検体のベースラインデータとの相関を検討した所、BMIと体重には弱い相関がみられたが、その他は相関が見られなかった。さらに、ループス腎炎に関しては病理型との関連も検討したが、顕著な関連は見られなかった。本マーカーは、濃度が低い方が完全寛解が遅く、腎機能悪化も多い傾向が見られ、濃度の高い方が予後が良い傾向が認められた。
    さらに、ループス腎炎患者血漿中のマーカー濃度についても検討を行った。10名のループス腎炎患者の血漿中のマーカー濃度を健常者と比較した所、尿同様に患者血症中でも高い傾向が認められた。
    マーカー代謝物の化学合成に少し時間を要しているが、おおむね計画通り進んでいる。
    共同研究先への結果のフィードバックを速やかに行い、必要に応じて追加検体を受け取れる体制を整えていく。

    本研究では、膜性腎症の中でも責任抗原が不明な特発性膜性腎症について未知の責任抗原の解明を目指すと共に、Phospholipase A2 receptor(PLA2R)やThrombospondin 7A(THSD7A)を含む各責任抗原に対する自己抗体を指標にした病態理解および新規診断法の開発に取り組んでいる。
    研究2年目の進捗は以下の通りである。未知の責任抗原の同定では、研究1年目に開発した患者血清を用いた免疫沈降法を用いて抗原検索を継続した。また、昨年度の実験で得られた新規抗原候補となるタンパク質の同定作業にも取り組んだ。質量分析により得られた新規抗原候補群からポドサイトに発現する膜タンパク質を抽出して、各候補抗原のcDNA断片を組み込んだ発現ベクターを作成し、各種組換えタンパク質を取得した。得られた抗原タンパク質を用いて患者血清に対する結合試験を開始した。一方、既知責任抗原であるPLA2Rのエピトープ解析では、海外の先行論文にて一次性膜性腎症患者がもつ自己抗体のエピトープとして報告されているシステインリッチドメイン(CysR)、Cタイプレクチンドメイン1番(CTLD1)、Cタイプレクチンドメイン5番(CTLD5)、Cタイプレクチンドメイン7番(CTLD7)、Cタイプレクチンドメイン8番(CTLD8)に対するエピトープ分布解析に取り組んだ。各ドメインの組換えタンパク質を調製して、抗PLA2R陽性一次性膜性腎症患者の診断時血清を用いて解析を実施した。その結果、日本人患者ではエピトープ分布と病勢・予後との間に海外症例で報告されたような明瞭な相関は認められず、日本人患者では診断時の抗PLA2R抗体濃度の方がより予後との相関が強いことが示された。
    未知抗原の同定では候補抗原の発現と患者自己抗体に対する結合性確認を繰り返す作業に移行できている。自己抗体濃度やエピトープ分布による病勢・予後解析では計画通りに推進できてデータの蓄積が進んでいる。
    順調に進展しているため今後も当初の研究計画に沿って進める。具体的には、未知抗原同定とPLA2R関連膜性腎症患者およびTHSD7A関連膜性腎症患者の血清を用いた自己抗体濃度およびエピトープ分布による病勢・予後診断法の検討を進める。

    Fibrosis is a key regulator of organ damage.myofibroblast is essential for rise of fibrosis, and it is said that MSC is one of the origin. We previously report that a cell surface and secreted protein, Meflin, is expressed in cultured MSCs, fibroblasts and pericytes, but not other types of cells including epithelial, endothelial and smooth muscle cells. We also found Meflin is a potential marker for cultured MSCs and focused on the mechanism of fibrosis by investigating Meflin.
    We discovered that Meflin expresses in intersititum and around the vascular pole of glomerulus. And its’ expression increases when glomerular inflammation and fibrosis progresses.We also investigated the manner of Meflin positive cells with Meflin reporter mice generated in our lab.
    In vitro study also suggested that Meflin is positively regulating kidney fibrosis.

    Because kidney biopsy essential for diagnosis is associated with risk of bleeding and requires hospitalization of patients, repeated examinations for the evaluation of therapeutic efficacy and disease recurrence are not encouraged.
    We hypothesized that surface molecules on inflammatory glomerular leukocytes leak into urine. Accordingly, we analyzed bio-samples from domestic and international patients with kidney diseases. The study revealed significant elevation of urinary CD11b with increased numbers of glomerular leukocytes expressing CD11b in patients with lupus nephritis, a major kidney complication of systemic lupus erhythematosus, and in patients with vasculitis. Further analysis of the diagnostic performance for predicting active lupus nephritis demonstrated marked superiority of urinary CD11b compared with two other leukocyte-derived molecules (CD163 and CD16b).

    In the present study, we aimed to elucidate the underlying mechanisms of chronic kidney disease (CKD) and hepatic steatosis caused by nutritional overburden more in details. Therefore, we investigated the role of CD147/Basigin (BSG) to maintain intracellular energy homeostasis, using high fat diet (HFD)-induced wild-type and BSG gene-deficient (BSGKO) mice. In the kidneys of BSGKO mice, vacuolar degeneration of tubular epithelial cells and accumulation of lipofuscin-like substances were remarkably suppressed. These findings might be due to the phenomena that transport of the substrates such as pyruvate and lactate in the cells was suppressed by BSG deficits subsequently leading to the the reduction of TCA cycle intermediates and enhanced ketogenesis through activation of free fatty acid beta oxidation. In the setting, augmented BSG protein might be due to the promotion of autophagy, but not translocation to nuclei.

    細胞外スルファターゼSulf2は、分子量約130kDaの分泌型酵素で細胞外での膜タンパクに付着している糖鎖の脱硫酸化を担いWnt, BMP, GDNF, FGFというヘパリン結合性因子のシグナル伝達を制御する物質である。
    腎臓領域ではSulf1およびSulf2が細胞外基質蓄積を制御し糖尿病性腎症悪化に寄与するとの既報がある。また、ヘパラン硫酸-S-ドメインの蓄積は原線維形成を促進し、腎臓での細胞毒性を促進するという知見が加わった。上記よりSulf2Tgは腎保護に寄与すると仮説を立て私はヒトSulf2全身強制発現マウス(HSulf2Tg)と血管内皮細胞特異的Sulf2強発現 (Tie2-Cre/Sulf2)を用いて、腎機能にどのように関与するか機序解明を目指した。
    初年度の計画としてはHSulf2Tgの腎障害惹起時に表現型の確認。腎障害を惹起していない野生型とHSulf2Tgを比較し双方ともに腎機能が正常であった。また、腎障害モデルとして交付申請書に記載した抗基底膜抗体により直接的に糸球体内皮細胞を障害する加速型馬杉腎炎モデルに加えて、アドリアマイシン腎症モデル、糖尿病モデルを作成。いずれのモデルにおいても、HSulf2Tgの方が 尿素窒素・クレアチニン・尿タンパクが低値であった。しかし、Tie2-Cre/Sulf2は野生型と比して尿素窒素・クレアチニン・尿タンパクのいずれも差異は認めなかった。

    Chronic antibody-mediated rejection is one of major obstacles to long-term graft outcome after kidney transplantation. We focused on preventive or preemptive medicine for de novo DSA production, because anti-rejection treatment has proved ineffective after manifestation of renal dysfunction. CD8+ T cell and B cell-targeting drug sensitivity test could be established. The expression level of CD40L on T cell would be a promising biomarker for antibody production. Potential value of miRNA (142-3p, 1913, 374-5p), mRNA (CIITA, CTLA-4) and donor-derived cell free DNA for preemptive treatment was elucidated. Graft accommodation induced by ABO incompatibility was elicited by up-regulation of CD55/59 and down-regulation of HLA class II through ERK inactivation and mTOR inactivation, respectively. Establishment of T cell indirect recognition assay, analysis of T cell receptor (TCR), and the feasibility of drug-induced graft accommodation should be next challenging subjects.

    【Background】PILRα expressed on leukocytes has regulatory functions in leukocyte β2 integrin activation during acute inflammation. Here, we investigated its roles in antibody-mediated glomerular inflammation.【Results】PILRα-/- mice with NTS-GN demonstrated severe glomerular injury. Enhanced glomerular neutrophil accumulation was observed in NTS-GN PILRα-/- only under pre-immunized conditions. PILRα-/- neutrophils exhibited enhanced spreading and adhesion to ICs compared to those in WT cells.【Conclusion】PILRα negatively regulates antibody-mediated neutrophil recruitment, leading to renal injury, by inhibiting Mac-1 integrin activation.

    We investigated the pathophysiological role of exogenously applied microRNA (miRNA) in sepsis-induced multiple organ injury. In vitro, we tested possible miRNAs which suppressed the production of pro-inflammatory cytokines. Of these, miR-146a displayed the highest suppressive effect. Sepsis was induced in mice via cecal ligation and puncture (CLP) and an intravenous injection of a complex of miR-146a-expressing plasmid and polyethyleneimine. Treatment with this complex significantly decreased the level of serum inflammatory cytokines, attenuated organ injury, and led to increased survival from sepsis. miR-146a-expressing plasmid was abundantly distributed in splenic macrophages. CLP mice treated with miR-146a displayed significantly decreased NF-κB activation in the spleen. The collective results support the conclusion that the induction of miR-146a expression in splenic macrophages prevents excessive inflammation and sepsis-induced multiple organ injury.

    In a system aiming at deep observation of the living body using multiphoton confocal laser microscope A1R MP (Nikon), administration of epoxy eicosatrienoic acids (EETs) inhibitor and adenosine inhibitor, induced the vasoconstrictive action in Midkine (MK) deficient mice. The blood vessels were contracted and blood flow was decreased, as blood pressure increased. The blood flow rate was rising. On the other hand, when a nicotinic acetylcholine receptor inhibitor was administered to evaluate the sympathetic nervous system, blood pressure dropped in MK deficient mice, indicating an increase in blood flow. MK has been shown to regulate renal and blood pressure via a vasodilator.

    In order to standardize treatment for membranous nephropathy (MN), we investigated the current status of diagnosis, treatment, and epidemiology of the MN in countries of Asia and the Pacific region including Japan. The medical treatment and patient registration system of MN were very different depending on the country. The prevalence of anti-PLA2R antibody in primary MN patients was reconfirmed in Japan as low as about 50%. On the other hand, the prevalence of PLA2R antibodies in patients in China, Taiwan and Korea were all 80%, equivalent to patients in Western countries. On the contrary, the prevalence of THSD7A antibody was slightly higher in Japan than in other countries. In countries where measurement of autoantibodies cannot be performed, it was concluded that pathological staining of antigens would be the first choice. This study was able to collect a lot of information for the standardization and diffusion of future MN medical care.

    We aimed to develop a novel drug discovery platform for medicine for congenital renal disease which was based on in vivo phenotype screening using kidney-visualized-transparent-zebrafish.
    As a result, we bred a new line of transparent zebrafish that is more growth efficiency and more transparency than conventional lines. Although, the gene editing-based congenital nephrotic syndrome model lines could not be generated during study period, the congenital whole-body calcification model transparent kidney visualized line was generated using a phosphorus transporter mutant line. As a result of a compound administration experiment using frying fish, it was possible to observe dose-dependent occurrence of edema, kidney malformation, disappearance of nephron, etc. according to the nephrotoxicity of the compound. These data demonstrated the feasibility of in vivo screening system using kidney visualized transparent zebrafish.

    Applicants' previous studies have identified mesenchymal stem cells (MSC) differentiation under conditions where the serum concentration of the culture solution of fetal membrane-derived MSC (FM-MSC) was changed to 2%. However, in the low serum culture method with a serum concentration of 2%, the proliferation ability of the FN-MSCs was attenuated, and the proliferation rate was decreased in passage3. When hFGF (human fibroblast growth factor) was added for the purpose of promoting the growth of MSCs and the culture medium was introduced, an improvement in the growth rate was obtained but the problem that the undifferentiated state was not maintained became clear. The FM- MSC could not give the same result as that of adipose tissue-derived MSC. This study suggested that low serum culture may be dependent on cell source.

    We studied on the clinical reality and pathophysiology of PLA2R-associated membranous nephropathy, a new concept of primary membranous nephropathy, in Japanese patients. We optimized the method of measuring PLA2R antibody according to the clinical situation of Japanese patients. The PLA2R antibody measurement at the time of renal biopsy was shown not only useful for differentiation of PLA2R-related membranous nephropathy but also useful for predicting prognosis. PLA2R antibody-positive patients who have a history of smoking have been shown to delay complete remission. Patients with a PLA2R antibody concentration of 50 RU/ml or more at the time of renal biopsy were shown to have a significantly worse renal prognosis.

    In Asian collaborative study, we analyzed suitable surrogate renal outcomes for clinical research. First, we established accurate renal function evaluation methods for Korean, Taiwan ,Thai and Indian CKD patients. Second, we analyzed utility of various renal outcomes in Asia. In health-check subject and CKD cohort studies, 30% decrease in eGFR could be surrogate renal outcome instead of hard end point including end stage kidney disease. Among IgA nephropathy patients, 50% increase in serum creatinine was good renal outcome to assess treatment effect and prognosis in renal biopsy. By surveillance of Asian renal outcome studies, GFR decline rate was sensitive and reliable renal outcome.

    The aim of this study is to elucidate the role of fructose metabolism by the primary enzyme of fructose, ketohexokinase (KHK) in hypertension. In this study, by using KHK knockout mice (KHK-KO), we found that the combination of fructose and high salt induced the elevation of blood pressure with decrease of sodium excretion and increase of mRNA expression of NHE3 in kidney in wild type mice (WT), but not in KHK-KO mice, and that fructose stimulation increased NHE activity accompanied by a decrease in intracellular cAMP that is dependent on KHK. These results suggest that fructose metabolism by KHK is involved in the development of salt-sensitive hypertension through increases of renal sodium reabsorption by NHE3.
