    Intracellular singlet oxygen (1O2) generation and detection help optimize the outcome of photodynamic therapy (PDT). Theranostics programmed for on-demand phototriggered 1O2 release and bioimaging have great potential to transform PDT. We demonstrate an ultrasensitive fluorescence turn-on sensor-sensitizer-RGD peptide-silica nanoarchitecture and its 1O2 generation-releasing-storing-sensing properties at the single-particle level or in living cells. The sensor and sensitizer in the nanoarchitecture are an aminomethyl anthracene (AMA)-coumarin dyad and a porphyrin or CdSe/ZnS quantum dots (QDs), respectively. The AMA in the dyad quantitatively quenches the fluorescence of coumarin by intramolecular electron transfer, the porphyrin or QD moiety generates 1O2, and the RGD peptide facilitates intracellular delivery. The small size, below 200 nm, as verified by scanning electron microscopy and differential light scattering measurements, of the architecture within the 1O2 diffusion length enables fast and efficient intracellular fluorescence switching by the tandem ultraviolet (UV)-visible or visible-near-infrared (NIR) photo-triggering. While the red emission and 1O2 generation by the porphyrin are continually turned on, the blue emission of coumarin is uncaged into 230-fold intensity enhancement by on-demand photo-triggering. The 1O2 production and release by the nanoarchitecture enable spectro-temporally controlled cell imaging and apoptotic cell death; the latter is verified from cytotoxic data under dark and phototriggering conditions. Furthermore, the bioimaging potential of the TCPP-based nanoarchitecture is examined in vivo in B6 mice.

    Signal peptides (SPs) and their fragments play important roles as biomarkers and substances with physiological functions in extracellular fluid. We previously reported that SP fragments were released into extracellular fluid via exosomes and bound to calmodulin (CaM), an exosomal component, in a cell-free system. However, it currently remains unclear whether CaM intracellularly interacts with SP fragments or is involved in the trafficking of these fragments to exosomes. Therefore, the present study examined the binding of CaM to SP fragments in T-REx AspALP cells, transformed HEK293 cells expressing amyloid precursor protein (APP) SP flanking a reporter protein, and their exosomes. APP SP fragments were detected in exosomes from T-REx AspALP cells in the absence of W13, a CaM inhibitor, but were present in lower amounts in exosomes from W13-treated cells. Cargo proteins, such as Alix, CD63, and CD81, were increased in W13-treated T-REx AspALP cells but were decreased in their exosomes. Furthermore, CaM interacted with heat shock protein 70 and CD81 in T-REx AspALP cells and this increased in the presence of W13. APP SP fragments were detected in intracellular CaM complexes in the absence of W13, but not in its presence. These results indicate that CaM functions as a key regulator of the transport of SP fragments into exosomes and plays novel roles in the sorting of contents during exosomal biogenesis.

    Background: Diabetes and obesity contribute to the pathogenesis of nonalcoholic steatohepatitis (NASH) and hepatocellular carcinoma (HCC). However, how diabetes and obesity accelerate liver tumorigenesis remains to be fully understood. Moreover, to verify the therapeutic potential of anti-diabetic drugs, there exists a strong need for appropriate animal models that recapitulate human pathophysiology of NASH and HCC. Methods: We established a novel murine model of NASH-associated liver tumors using genetically obese melanocortin 4 receptor-deficient mice fed on Western diet in combination with a chemical procarcinogen, and verified the validity of our model in evaluating drug efficacy. Findings: Our model developed multiple liver tumors together with obesity, diabetes, and NASH within a relatively short period (approximately 3 months). In this model, sodium glucose cotransporter 2 inhibitor Tofogliflozin prevented the development of NASH-like liver phenotypes and the progression of liver tumors. Tofogliflozin attenuated p21 expression of hepatocytes in non-tumorous lesions in the liver. Interpretation: Tofogliflozin treatment attenuates cellular senescence of hepatocytes under obese and diabetic conditions. This study provides a unique animal model of NASH-associated liver tumors, which is applicable for assessing drug efficacy to prevent or treat NASH-associated HCC.

    Hypothermia is a significant sign of sepsis, which is associated with poor prognosis, but few mechanisms underlying the regulation of hypothermia are known. Inducible nitric oxide synthase (iNOS) is a key inflammatory mediator of sepsis. However, the therapeutic benefit of iNOS inhibition in sepsis is still controversial, and requires elucidation in an accurate model system. In this study, wild-type (WT) mice showed temperature drops in a biphasic manner at the early and late phase of sepsis, and all mice died within 48 h of sepsis. In contrast, iNOS-knockout (KO) mice never showed the second temperature drop and exhibited improved mortality. Plasma nitric oxide (NO) levels of WT mice increased in the late phase of sepsis and correlated to hypothermia. The results indicate that iNOS-derived NO during the late phase of sepsis caused vasodilation-induced hypothermia and a lethal hypodynamic state. The expression of the iNOS mRNA was high in the lung of WT mice with sepsis, which reflects the pathology of acute respiratory distress syndrome (ARDS). We obtained the results in a modified keyhole-type cecal ligation and puncture model of septic shock induced by minimally invasive surgery. In this accurate and reproducible model system, we transplanted the bone marrow cells of GFP transgenic mice into WT and iNOS-KO mice, and evaluated the role of increased pulmonary iNOS expression in cell migration during the late phase of sepsis. We also investigated the quantity and type of bone marrow-derived cells (BMDCs) in the lung. The number of BMDCs in the lung of iNOS-KO mice was less than that in the lung of WT mice. The major BMDCs populations were CD11b-positive, iNOS-negative cells in WT mice, and Gr-1-positive cells in iNOS-KO mice that expressed iNOS. These results suggest that sustained hypothermia may be a beneficial guide for future iNOS-targeted therapy of sepsis, and that iNOS modulated the migratory efficiency and cell type of BMDCs in septic ARDS.

    Visualization of direct neuronal activity to understand brain function is one of the most important challenges in neuroscience. We have previously demonstrated that in vivo and in vitro gene expression of the ferritin reporter system could be detected by magnetic resonance imaging (MRI). In addition, increased neuronal activity induces Arc, an immediate early gene, and insertion of a destabilized fluorescent reporter dVenus under Arc promoter control has been used for monitoring neuronal activities in the brain by optical imaging. In this study, to visualize Arc promoter-driven neuronal activities directly, we generated transgenic mice and cell lines that express a destabilized fusion reporter ferritin-mKate2 under Arc promoter control. When transgenic mice and cell lines were treated with pilocarpine, a non-selective muscarinic agonist, an increase in T2-weighted image signal was successfully found in neuronal cells. There was a difference in peak time between MRI and fluorescence imaging, which might result from the binding process of iron with ferritin. Visualization of Arc promoter-driven neuronal activity is essential to understand neural mechanisms underlying cognitive processes and complex behaviors, and could be a useful tool for therapeutic approaches in the brain by MRI.

    Alterations in the intracellular ion environment have been identified as one of the signals playing a critical role in the control of cellular proliferation and differentiation; however, the mechanisms responsible for signal transduction remain unclear. Recent studies have reported that channelrhodopsin-2 (ChR2) is a rapidly gated blue light (BL)-sensitive cation channel suitable for the non-invasive control of ion influx. We herein examined the expression of differentiation-associated markers by photo-activation and its signal transduction in ChR2-expressing OS3 (OS3ChR2) cells, which are clonal bipotential glial progenitor cells. Increases were observed in intracellular Na+ and Ca2+ concentrations in OS3ChR2 cells with BL exposure. Alterations in the intracellular ion environment, particularly in Ca2+, led to increases in the expression of oligodendrocyte markers including galactocerebrosides (GalC) and decreases in that of astrocyte markers such as glial fibrillary acidic protein (GFAP). These alterations also triggered activation of the ERK1/2 signaling pathway, which is involved in cell survival, and PI3K/Akt/mTOR signaling pathway, which is involved in oligodendrocyte differentiation, characterized by GalC expression. Moreover, when photo-activated OS3ChR2 cells were injected into mice with lysophosphatidyl choline (LPC)-induced demyelination, deficits in motor function were reduced. Our results demonstrated that signal transduction by ChR2-expressing glial progenitor cells may be controlled through alterations induced in the intracellular ion environment by photo-activation and results in oligodendrOcyte differentiation from glial progenitor cells. Our results also suggest that ChR2-expressing glial progenitor cells have potential as a useful tool for therapeutic approaches to brain and spinal cord disorders associated with oligodendrocyte dysfunctions.

    Magnetic nanoparticles (MNPs) generate heat when a high-frequency magnetic field (HFMF) is applied to them. Induction heat is useful not only for hyperthermia treatment but also as a driving force for drug-release. beta-Cyclodextrin (CD) can act as drug container because of its inclusion properties. Drugs incorporated in the CD can thus be released through the use of induction heating, or hyperthermic effects, by applying a HFMF. In this study, we have synthesized folic acid (FA) and CD-functionalized superparamagnetic iron oxide nanoparticles, FA-CD-SPIONs, by chemically modifying SPIONs derived from iron(III) allylacetylacetonate. FA is well-known as a targeting ligand for breast cancer tumor and endows the SPIONs with cancer-targeting capability. Immobilization of FA and CD on spinel iron oxide nanoparticles was confirmed by Fourier transform IR (FTIR) and X-ray photoelectron spectroscopy (XPS). The FA-CD-SPIONs have a hydrodynamic diameter of 12.4 nm and prolonged stability in water. They are superparamagnetic with a magnetization of 51 emu g(-1) at 16 kOe. They generate heat when an alternating current (AC) magnetic field is applied to them and have a specific absorption rate (SAR) of 132 W g(-1) at 230 kHz and 100 Oe. Induction heating triggers drug release from the CD cavity on the particle - a behavior that is controlled by switching the HFMF on and off. The FA-CD-SPIONs are noncytotoxic for cells. Thus, FA-CD-SPIONs can serve as a novel device for performing drug delivery and hyperthermia simultaneously.

    Quantum dots (QDs) have been used to study the effects of fluorescent probes for biomolecules and cell imaging. Adipose tissue-derived stem cells, which carry a relatively lower donor site morbidity, while yielding a large number of stem cells at harvest, were transduced with QDs using the octa-arginine peptide (R8) cell-penetrating peptide (CPP). The concentration ratio of QDs:R8 of 1 x 10(4) was optimal for delivery into ASCs. No cytotoxicity was observed in ASCs transduced with less than 16 nM of QDs655. In addition, >80% of the cells could be labeled within 1 h and the fluorescent intensity was maintained at least for 2 weeks. The ASCs transduced with QDs using R8 could be differentiated into both adipogenic and osteogenic cells, thus suggesting that the cells maintained their stem cell potency. The ASCs labeled with QDs using R8 were further transplanted subcutaneously into the backs of mice or into mice through the tail vein. The labeled ASCs could be imaged with good contrast using the Maestro in vivo imaging system. These data suggested that QD labeling using R8 could be utilized for the imaging of ASCs.

    Most CNS diseases begin with inflammation with subsequent neural damage eventually occurring; however, the process leading from the onset of inflammation to neural damage remains obscure. We used an artificial brain injury mouse model and examined how neural damage occurred in the brain parenchyma. The damaged area in each mouse was clearly observed by magnetic resonance imaging (MRI), and the progression of damage was observed to occur in a biphasic manner (acute damage, within 1 week; delayed damage, after 2 weeks). We found that the delayed neural damage was absent in iNOS-deficient mice (iNOS-KO mice). Then, we analyzed brain tissues and determined that delayed neural damage was accompanied by an increase in the levels of NO end products and iNOS expression, with accumulation of iNOS-expressing microglia around the injured area. In addition, the expression of IL-1β mRNA was increased in areas affected by acute damage, but not in those affected by delayed damage. These findings suggest that delayed neural damage might arise from NO production by iNOS-expressing activated microglia and that such activated microglia might become a therapeutic target for many CNS diseases.

    Magnetic resonance imaging (MRI) is a minimally invasive way to provide high spatial resolution tomograms. However, MRI has been considered to be useless for gene expression imaging compared to optical imaging. In this study, we used a ferritin reporter, binding with biogenic iron, to make it a powerful tool for gene expression imaging in MRI studies. GL261 mouse glioma cells were over-expressed with dual-reporter ferritin-DsRed under beta-actin promoter, then gene expression was observed by optical imaging and MRI in a brain tumor model. GL261 cells expressing ferritin-DsRed fusion protein showed enhanced visualizing effect by reducing T2-weighted signal intensity for in vitro and in vivo MRI studies, as well as DsRed fluorescence for optical imaging. Furthermore, a higher contrast was achieved on T2-weighted images when permeating the plasma membrane of ferritin-DsRed-expressing GL261. Thus, a ferritin expression vector can be used as an MRI reporter to monitor in vivo gene expression.

    Dementia is a frequent complication of Parkinson's disease (PD) and usually occurs late in the protracted course of the illness. We have already reported numerous MHC class II-positive microglia in the hippocampus in PD patients, and that this phenomenon may be responsible for functional changes in the neurons and the cognitive decline in PD patients. In this study, we have investigated the distribution of activated microglia and the immunohistochemical and the mRNA expression of several cytokines and neurotrophic factors of the hippocampus in PD and dementia with Lewy bodies (DLB). The brains from five cases of PD and five cases of DLB that were clinically and neuropathologically diagnosed, and those from four normal controls (NC) were evaluated by immunohistochemistry using anti-HLA-DP, -DQ, -DR (CR3/43), anti-alpha-synuclein, anti-brain-derived neurotrophic factor (BDNF), and anti-glial fibrillary acidic protein antibodies. In addition, the mRNA expressions of cytokines (IL-1alpha, IL-1beta, TNF-alpha, IL-6, TGF-beta) and neurotrophic factors (BDNF, GDNF, NGF, NT-3) of these brains were evaluated by the reverse transcription-PCR method. MHC class II-positive microglia were distributed diffusely in the hippocampus of PD and DLB brains. Although the cytoplasm of pyramidal and granular cells of the hippocampus in NC brains was strongly stained by anti-BDNF antibodies, it was only weakly stained in PD and DLB brains. The mRNA expression of IL-6 was significantly increased in the hippocampus of PD and DLB brains, and that of BDNF was significantly decreased in the hippocampus of DLB brains. The increased number of activated microglia and the production of neurotrophic cytokines such as IL-6, together with the decreased expression of the neurotrophic factors of neurons in the hippocampus of PD and DLB brains, may be related to functional cellular changes associated with dementia.

    Recent studies have described the possible transdifferentiation of bone marrow cells (BMC) into neurons and glia when they migrate to the brain. However, we have reported that some immature BMC migrating into the brain parenchyma after bone marrow transplantation express early hematopoietic markers but not neural or glial markers. The present study further characterizes transplanted BMC that migrate to the brain. Double immunolabeling confirmed that BMC migrating to the brain expressed hematopoietic but not neural markers, such as nestin, microtubule-associated protein-2 and glial fibrillary acidic protein, even 4 and 18 weeks after bone marrow transplantation. BMC that expressed green fluorescent protein also expressed hematopoietic but not neural markers when cultured with mixed brain cells according to double immunolabeling and single-cell dissection using a laser. Analysis of the DNA content indicated that most of the migrated BMC were arrested at the G0/G1 phase, and aneuploidy or tetraploidy was undetectable. Thus, BMC that migrate to the brain probably have preserved hematopoietic properties under physiological conditions.

    We examined the expression and function of beta-adrenergic receptor (beta-AR) subtypes in both isolated primary rat microglia and a rat microglial cell line. RT-PCR analyses revealed that microglia expressed beta(1)- and beta(2)-ARs but not beta(3)-ARs, whereas rat primary peritoneal macrophages expressed only beta(2)-ARs. Stimulation of beta-ARs on microglia by norepinephrine (NE) resulted in an increase in the level of intracellular cAMP and the subsequent expression of interleukin-1beta mRNA. These effects were prevented by propranolol. Similar results were obtained with other selective beta(1)-AR agonists and antagonists. beta(2)-ARs on microglia were also functional. It is possible that noradrenergic innervations participate in the control of microglial functions via beta(1)-ARs on microglia in the brain, because NE has high affinity for beta(1)- and beta(3)-ARs but little or no affinity for beta(2)-ARs. It seems physiologically significant that microglia can be controlled by NE, which predominates over epinephrine in the brain, whereas macrophages in peripheral tissues can be controlled by epinephrine, which is at higher levels in peripheral tissues.

    Bone marrow transplantation with GFP-expressing cells from GFP-transgenic mice resulted in migration of GFP-positive cells into peripheral tissues and brain parenchyma. Most of these cells were observed as colony-like clusters. GFP-positive clusters in the brain were stained by antibody for ER-MP12, but those in the peripheral tissues were not. Since ER-MP12 antigen has been reported as a marker for murine early-stage myeloid precursor, this might suggest that some parts of phagocytic cells in the brain parenchyma such as microglia are derived from undifferentiated pluripotent hematopoietic cells.

    Hypothermia is a significant sign of sepsis, which is associated with poor prognosis, but few mechanisms underlying the regulation of hypothermia are known. Inducible nitric oxide synthase (iNOS) is a key inflammatory mediator of sepsis. However, the therapeutic benefit of iNOS inhibition in sepsis is still controversial, and requires elucidation in an accurate model system. In this study, wild-type (WT) mice showed temperature drops in a biphasic manner at the early and late phase of sepsis, and all mice died within 48 h of sepsis. In contrast, iNOS-knockout (KO) mice never showed the second temperature drop and exhibited improved mortality. Plasma nitric oxide (NO) levels of WT mice increased in the late phase of sepsis and correlated to hypothermia. The results indicate that iNOS-derived NO during the late phase of sepsis caused vasodilation-induced hypothermia and a lethal hypodynamic state. The expression of the iNOS mRNA was high in the lung of WT mice with sepsis, which reflects the pathology of acute respiratory distress syndrome (ARDS). We obtained the results in a modified keyhole-type cecal ligation and puncture model of septic shock induced by minimally invasive surgery. In this accurate and reproducible model system, we transplanted the bone marrow cells of GFP transgenic mice into WT and iNOS-KO mice, and evaluated the role of increased pulmonary iNOS expression in cell migration during the late phase of sepsis. We also investigated the quantity and type of bone marrow-derived cells (BMDCs) in the lung. The number of BMDCs in the lung of iNOS-KO mice was less than that in the lung of WT mice. The major BMDCs populations were CD11b-positive, iNOS-negative cells in WT mice, and Gr-1-positive cells in iNOS-KO mice that expressed iNOS. These results suggest that sustained hypothermia may be a beneficial guide for future iNOS-targeted therapy of sepsis, and that iNOS modulated the migratory efficiency and cell type of BMDCs in septic ARDS.

    Visualization of direct neuronal activity to understand brain function is one of the most important challenges in neuroscience. We have previously demonstrated that in vivo and in vitro gene expression of the ferritin reporter system could be detected by magnetic resonance imaging (MRI). In addition, increased neuronal activity induces Arc, an immediate early gene, and insertion of a destabilized fluorescent reporter dVenus under Arc promoter control has been used for monitoring neuronal activities in the brain by optical imaging. In this study, to visualize Arc promoter-driven neuronal activities directly, we generated transgenic mice and cell lines that express a destabilized fusion reporter ferritin-mKate2 under Arc promoter control. When transgenic mice and cell lines were treated with pilocarpine, a non-selective muscarinic agonist, an increase in T2-weighted image signal was successfully found in neuronal cells. There was a difference in peak time between MRI and fluorescence imaging, which might result from the binding process of iron with ferritin. Visualization of Arc promoter-driven neuronal activity is essential to understand neural mechanisms underlying cognitive processes and complex behaviors, and could be a useful tool for therapeutic approaches in the brain by MRI.

    Alterations in the intracellular ion environment have been identified as one of the signals playing a critical role in the control of cellular proliferation and differentiation; however, the mechanisms responsible for signal transduction remain unclear. Recent studies have reported that channelrhodopsin-2 (ChR2) is a rapidly gated blue light (BL)-sensitive cation channel suitable for the non-invasive control of ion influx. We herein examined the expression of differentiation-associated markers by photo-activation and its signal transduction in ChR2-expressing OS3 (OS3ChR2) cells, which are clonal bipotential glial progenitor cells. Increases were observed in intracellular Na+ and Ca2+ concentrations in OS3ChR2 cells with BL exposure. Alterations in the intracellular ion environment, particularly in Ca2+, led to increases in the expression of oligodendrocyte markers including galactocerebrosides (GalC) and decreases in that of astrocyte markers such as glial fibrillary acidic protein (GFAP). These alterations also triggered activation of the ERK1/2 signaling pathway, which is involved in cell survival, and PI3K/Akt/mTOR signaling pathway, which is involved in oligodendrocyte differentiation, characterized by GalC expression. Moreover, when photo-activated OS3ChR2 cells were injected into mice with lysophosphatidyl choline (LPC)-induced demyelination, deficits in motor function were reduced. Our results demonstrated that signal transduction by ChR2-expressing glial progenitor cells may be controlled through alterations induced in the intracellular ion environment by photo-activation and results in oligodendrOcyte differentiation from glial progenitor cells. Our results also suggest that ChR2-expressing glial progenitor cells have potential as a useful tool for therapeutic approaches to brain and spinal cord disorders associated with oligodendrocyte dysfunctions.

    Signal peptides (SPs) and their fragments play important roles as biomarkers and substances with physiological functions in extracellular fluid. We previously reported that SP fragments were released into extracellular fluid via exosomes and bound to calmodulin (CaM), an exosomal component, in a cell-free system. However, it currently remains unclear whether CaM intracellularly interacts with SP fragments or is involved in the trafficking of these fragments to exosomes. Therefore, the present study examined the binding of CaM to SP fragments in T-REx AspALP cells, transformed HEK293 cells expressing amyloid precursor protein (APP) SP flanking a reporter protein, and their exosomes. APP SP fragments were detected in exosomes from T-REx AspALP cells in the absence of W13, a CaM inhibitor, but were reduced by W13 treatment. Cargo proteins, such as Alix, CD63, and CD81, were increased in W13-treated T-REx AspALP cells but were decreased in their exosomes. Furthermore, CaM interacted with heat shock protein 70 and CD81 in T-REx AspALP cells and this increased in the presence of W13. APP SP fragments were detected in intracellular CaM complexes in the absence of W13, but not in its presence. These results indicate that CaM functions as a key regulator of the transport of SP fragments into exosomes and plays novel roles in the sorting of contents during exosomal biogenesis.

    When demyelinated NG2-ChR2 mice, which express channelrhodopsin-2 (ChR2) in NG2-positive glial progenitor cells, are exposed to blue light, not only some NG2-positive glial progenitor cells are differentiated into oligodendrocytes, but also accumulation of CD206 (an M2 marker)-positive microglia are found around the demyelinated area. Although these contribute to recovery of demyelinating symptoms, it remains unclear how the microglial M1 to M2 polarity switch occurs. In this study, we examined the effect of exosomal miRNAs from glial progenitor cells in microglial polarization at the demyelinated area since exosomes play important roles in intercellular communications via miRNAs. In miRNA analysis of exosomes derived from OS3ChR2, a ChR2-expressing NG2 glial progenitor cell line, in the presence (BL) or absence (N) of blue light exposure, inflammatory and M1 polarization-related miRNAs such as miR-155-5p, miR-743b-3p, and miR-291a-3p were decreased in exosomes from OS3ChR2 BL. In microglia treated with exosomes from OS3ChR2 BL, inflammatory-related mRNA expressions such as IL-1, TNF, and iNOS (an M1 marker) and CD206 mRNA expression were not altered as compared to microglia without exosome treatment. On the other hand, in microglia treated with exosomes from OS3ChR2 N, inflammatory-related mRNA expressions were increased and CD206 mRNA expression was decreased. Many iNOS-positive microglia and few CD206-positive microglia were found at corpus callosum of demyelinated mice. When exosomes from OS3ChR2 N were injected into the corpus callosum, iNOS-positive microglia were increased. When exosomes from OS3ChR2 BL were injected, iNOS-positive microglia were decreased and CD206-positive microglia were increased around the demyelinated area. Further, when miR-155-5p inhibitor was injected into the corpus callosum of demyelinated mice, iNOS-positive microglia were decreased and CD206-positive microglia were increased. These indicate that differentiated glial progenitor cells have a potential to control microglial polarity via exosomes. In addition, these suggested that glial progenitor cells would communicate to microglia with exosomal miRNA such as miR-155-5p in the demyelinated mice.

    Channel rhodopsin-2 (ChR2), derived from Chlamydomonas reinhardtii, is an ion channel activated by blue light. As ChR2-expressing neurons are induced action potentials by blue light exposure, ChR2 is expected to be useful for analysis of neural circuit and functions. Functions of glial cells are also regulated via ion fluxes, some of which are involved in communication between glial cells and neurons and are essential for brain functions. In this study, ChR2-EYFP gene was transferred in GL261 ce

    腫瘍は我が国の死因の第一であり、その診断・治療法の開発は最重要課題である。手術技術の向上や分子標的化薬物の開発によりさまざまな腫瘍を除去することができるようになってきたが、それでもなお腫瘍が高い死因となっているのは腫瘍の転移を抑制する治療薬がほとんど存在しないことが要因の1つとしてあげられる。最近我々は腫瘍が転移生着する際に必要な「腫瘍ニッシェ」を形成する細胞群を見いだし、それらを濃縮分離できる可能性を示した。そこで本開発ではこれらの細胞特性に基づいた腫瘍転移の制御による新しい腫瘍治療法の開発をめざす。この手法を応用して腫瘍転移前の部位を検出し腫瘍転移の早期発見が可能な新しい診断法が開発できる。さらに、腫瘍切除後の腫瘍転移を抑制し、腫瘍が定着しにくい環境へ変化させる予後の良好な治療も可能になると考えられる。

    脱髄部位においてグリア前駆細胞を刺激しオリゴデンドロサイトへの分化や再ミエリン化を誘導する際に、グリア前駆細胞がその周囲のミクログリアとどのように相互作用するのかはよくわかっていない。分化誘導によってグリア前駆細胞の放出する細胞外小胞(EV)の性質が変化することや、そのEVをミクログリアが取り込むことから、EVを介した細胞間相互作用が再ミエリン化に重要である可能性がある。本研究では、グリア前駆細胞が放出するEVをミクログリアに作用させた際に、再ミエリン化にどのように関わるかを分子レベルで明らかにし、将来的な再生医療応用や治療薬開発へと展開するための基盤を確立する。
    光感受性陽イオンチャネルchannelrhodopsin-2(ChR2)を発現させたグリア前駆細胞を光刺激することで、脱髄部位においてオリゴデンドロサイトへの分化と再ミエリン化が生じるが、光刺激したグリア前駆細胞がその周囲の細胞とどのように相互作用するのかはよくわかっていない。本研究課題は、光刺激により分化誘導されたグリア前駆細胞が放出する細胞外小胞(EV)とミクログリアの相互作用に着目し、EV応答により生じたミクログリアの機能変化が再ミエリン化にどのように関わるのかを明らかにし、将来的な再生医療応用や新規治療薬開発へと展開するための基盤を確立することを目的としている。今年度は、分化誘導によってグリア前駆細胞から放出されるEVの性質がどのように変化するか、またその機序について検討した。ChR2を遺伝子導入したグリア前駆細胞株OS3ChR2細胞に光刺激を行うと、放出されるマイクロベシクル(LEV)やエクソソーム(SEV)の平均粒子径に変化はなかったが、細胞当たりのLEVおよびSEVの放出量が増大した。また、光刺激の有無によって放出されたSEVを同じタンパク量で比較すると、Alixやテトラスパニンの含有量が光刺激群で低下していた。さらに、光刺激の有無によって放出されたEVに含有されるmiRNAについてアレイ分析を行うと、EV中に含有されるmiRNAのうち増減するmiRNAが複数存在していた。SEVの放出にはendosomal sorting complexes required for transport (ESCRT)依存的経路と非依存的経路が存在するので、光刺激による細胞当たりのSEV放出増大がどの経路を介するかを調べたところ、ESCRT依存的/非依存的経路の両方の経路を介していた。また、その際にはERK1/2とAkt両方のシグナル経路の活性化が寄与することがわかった。
    令和2年度の当初予定は、ChR2発現グリア前駆細胞から放出されるEVの分析としてEV構成物質に関する分析とEV放出に関わる分子機序の分析を行うことであった。これらの項目において予定通り実施し、成果を得ることができた。
    令和3年度以降は、グリア前駆細胞から放出されるEVがミクログリアの機能にどのように変化を及ぼすかについて検討する。また、脱髄モデルマウスにおいてEVに応答したミクログリアが再ミエリン化にどのような影響を及ぼすかについて解析する。

    We examined optogenetic control of oligodendrocyte differentiation from channelrhodopsin-2(ChR2)-expressing glial progenitors by photo-activation. When ChR2-expressing glial progenitors were exposed to blue light, the increases in intracellular Na+ and Ca2+ concentrations occurred. It triggered activation of PI3K/Akt/mTOR signaling and resulted in oligodendrocyte differentiation from glial progenitors. Moreover, when NG2-ChR2 mice, which NG2 glial progenitors expressed ChR2-EYFP, were induced demyelination using lysophosphatidylcholine treatment, photo-activated glial progenitors around demyelinated regions differentiated into oligodendrocytes, and deficits in motor function were reduced. These results suggest that ChR2-expressing glial progenitors have potential as a useful tool for therapeutic approaches to brain and spinal cord disorders associated with oligodendrocyte dysfunctions.
