    Alzheimer’s disease (AD) is an age-related and progressive neurodegenerative disorder. It is widely accepted that AD is mainly caused by the accumulation of extracellular amyloid β (Aβ) and intracellular neurofibrillary tau tangles. Aβ begins to accumulate years before the onset of cognitive impairment, suggesting that the benefit of currently available interventions would be greater if they were initiated in the early phases of AD. To understand the mechanisms of AD pathogenesis, various transgenic mouse models with an accelerated accumulation of Aβ and tau tangles have been developed. However, none of these models exhibit all pathologies present in human AD. To overcome these undesirable phenotypes, APP knock-in mice, which were presented with touchscreen-based tasks, were developed to better evaluate the efficacy of candidate therapeutics in mouse models of early-stage AD. This review assesses several AD mouse models from the aspect of biomarkers and cognitive impairment and discusses their potential as tools to provide novel AD therapeutic approaches.

    Psychological stresses such as social loss and separation during childhood induce hardship, referred to as emotional pain. These experiences are well-documented risk factors for the development of physical pain in adulthood. However, the underlying neuronal mechanisms of this exacerbation of pain are largely unknown, and consequently there is no effective pharmacotherapy. In this study, we sought to determine whether infant maternal separation (MS) contributes to aggravation of neuropathic pain in adult mice. MS increased anxiety- and depression-like behavioral responses to adult stress. In MS animals, chronic constriction injury (CCI) heightened the sensory dimension of chronic pain relative to that of control mice. However, MS mice treated with fluoxetine for 4 weeks after MS did not exhibit augmentation of allodynia, and their emotional response was attenuated. Microglia were more abundant in the spinal cord in MS/CCI mice than in control/CCI mice. These results suggest that emotional impairment is related to augmentation of neuropathic pain, and that dysfunction of microglial activation contributes to heightened pain sensitivity.

    Patients suffering from neuropsychiatric disorders such as substance use and addiction disorders show impaired decision-making, which may be associated with their psychiatric disorders. Previously, using a gambling test for rodents, we demonstrated that methamphetamine-dependent rats showed alterations in their decision-making strategy. In this study, we investigated the effect of nicotine on impaired decision-making strategy in rats which have been treated repeatedly with methamphetamine. Nicotine has previously been shown to have therapeutic effects on attentional and cognitive abnormalities in psychosis. Rats were administered methamphetamine subcutaneously (sc) at 4 mg/kg once a day, for 30 days, and their decision-making was then assessed with a rodent gambling task. We found that methamphetamine-treated rats preferred the high-risk/high-return actions, which is consistent with our previous findings. Methamphetamine-induced impairment of decision-making was reversed by daily nicotine treatment (0.3 mg/kg, sc). This effect was associated with the reduction of lose-shift behavior after negative reward prediction error. Repeated treatment with nicotine had no effects on arm-choice behavior in naïve rats. Varenicline, an α4β2-nicotinic acetylcholine receptor partial agonist, also ameliorated the altered decision-making in methamphetamine-treated rats. Our findings suggest that nicotine treatment is useful for ameliorating the altered decision-making caused by methamphetamine treatment, and that the α4β2-nicotinic acetylcholine receptor is a therapeutic target for poor decision-making.

    <p>Decision making in complex and uncertain situations is a fundamental adaptive process resulting from the integration of several executive functions. Impaired decision-making is a symptomatic feature of a number of psychiatric disorders. In general, patients with psychiatric disorders show a propensity to prefer actions associated with large short-term gains but long-term losses preferentially to those associated with small but long-term gains. They are more likely to select risky options and show an altered temporal horizon of risks and benefits. Moreover, clinical studies report that dopamine therapy induce impaired decision-making in patients with dopaminergic dysfunction such as Parkinson's disease and Redox-less syndrome. Thus, to establish and optimize the animal model of impaired decision-making is important for development of new therapeutic strategy in these disorders.</p><p>To clarify the underlying neurobiology of decision-making, we conducted a study in healthy mice by using a mouse gambling operant test based on uncertainty and conflicting choices. Mice chose the low-risk / low-reward option on the reward amount- and provability-dependent manner. Our findings suggest that healthy mice prefer risk-aversive choice in this operant test as dose man in Iowa gambling test.</p>

    <p>Alzheimer's disease (AD) is a progressive disease characterized by loss of memory and other important mental functions. Accumulation of amyloid beta (Aβ) and fibrillary tangles are the main pathological hallmarks of this disease. Emerging data suggest that the disease process begins years before clinical diagnostic confirmation; thus, methods to improve early detection would provide opportunities for early intervention to delay progressive cognitive decline and disease onset. In our research we assessed the cognitive abilities of <i>APP</i><sup><i>NL-G-F/NL-G-F</i></sup> knock-in (<i>APP-</i>KI) mice with a touch screen-based automated test battery and water maze test. These tests are mainly dependent on the brain regions that are prone to Aβ accumulation at the earliest stages of the disease. We subjected male 6- and 11-months old <i>APP-</i>KI mice in water maze test where only older mice showed significantly worsened behavior than wild-type mice. However, using touchscreen based behavioral test it was possible to detect cognitive impairment in <i>APP-</i>KI mice at an early (4 months) stage while classical behavioral tests shows comparable results between wild-type and disease model mice. </p>

    <p>Decision-making is a key activity process that influences many aspects of daily living and both mental and physical health. In general, healthy participants reveal rational choice, but patients with neuropsychiatric disorders reveal irrational and risky choice in decision-making. Addiction is one of typical diseases revealed risky decision-making, addicts select risky action and options that confer short-term rewards at the cost of long-term disadvantages. Thus, irrational and risky decision-making is recognized as a core problem in patients with neuropsychiatric disorders, and a better understanding of the mechanisms underlying altered decision-making would provide insights into potential therapeutic approaches for these diseases. However, the neural pathway and substrates underlying these deficits are particularly unknown. Recently, we found that insular cortex is one of key regions for risky decision-making in an animal model of methamphetamine addiction, by using the designer receptor exclusively activated by designer drug (DREADD) technology, and that GABAergic dysfunction in insular cortex is involved in evaluating the subjective value of reward and reward prediction error. These brain dysfunctions would be related to risk taking behavior in addiction. In this review, we introduced the possible neural pathway related to risky decision-making and behavioral changes in choice strategy using adeno associated virus (AAV).</p>

    Patients suffering from neuropsychiatric disorders such as substance-related and addictive disorders exhibit altered decision-making patterns, which may be associated with their behavioral abnormalities. However, the neuronal mechanisms underlying such impairments are largely unknown. Using a gambling test, we demonstrated that methamphetamine (METH)-treated rats chose a high-risk/high-reward option more frequently and assigned higher value to high returns than control rats, suggestive of changes in decision-making choice strategy. Immunohistochemical analysis following the gambling test revealed aberrant activation of the insular cortex (INS) and nucleus accumbens in METH-treated animals. Pharmacological studies, together with in vivo microdialysis, showed that the insular neural system played a crucial role in decision-making. Moreover, manipulation of INS activation using designer receptor exclusively activated by designer drug technology resulted in alterations to decision-making. Our findings suggest that the INS is a critical region involved in decision-making and that insular neural dysfunction results in risk-taking behaviors associated with altered decision-making.

    Attention deficit/hyperactivity disorder (ADHD) has been reported in association with resistance to thyroid hormone, a disease caused by a mutation in the thyroid hormone receptor β (TRβ) gene. TRβ is a key protein mediating down-regulation of thyrotropin (TSH) expression by 3,3',5-tri-iodothyronine (T3), an active form of thyroid hormone. Dysregulation of TSH and its receptor (TSHR) is implicated in the pathophysiology of ADHD but the role of TSHR remains elusive. Here, we clarified a novel role for TSHR in emotional and cognitive functions related to monoaminergic nervous systems. TSHR knockout mice showed phenotypes of ADHD such as hyperactivity, impulsiveness, a decrease in sociality and increase in aggression, and an impairment of short-term memory and object recognition memory. Administration of methylphenidate (1, 5 and 10mg/kg) reversed impulsiveness, aggression and object recognition memory impairment. In the knockout mice, monoaminergic changes including decrease in the ratio of 3-methoxy-4-hydroxyphenylglycol/noradrenaline and increase in the ratio of homovanillic acid/dopamine were observed in some brain regions, accompanied by increase in the expression of noradrenaline transporter in the frontal cortex. When TSH was completely suppressed by the supraphysiological administration of T3 to the adult mice, some behavioral and neurological changes in TSHR KO mice were also observed, suggesting that these changes were not due to developmental hypothyroidism induced by the inactivation of TSHR but to the loss of the TSH-TSHR pathway itself. Taken together, the present findings suggest a novel role for TSHR in behavioral and neurological phenotypes of ADHD.

    Soluble oligomeric amyloid β (oAβ) causes synaptic dysfunction and neuronal cell death, which are involved in the pathogenesis of Alzheimer's disease (AD). The hematopoietic growth factor granulocyte-colony stimulating factor (G-CSF) is expressed in the central nervous system (CNS) and drives neurogenesis. Here we show that G-CSF attenuated oAβ neurotoxicity through the enhancement of the enzymatic activity of Aβ-degrading enzyme neprilysin (NEP) in neurons, while the NEP inhibitor thiorphan abolished the neuroprotection. Inhibition of MEK5/ERK5, a major downstream effector of G-CSF signaling, also ablated neuroprotective effect of G-CSF. Furthermore, intracerebroventricular administration of G-CSF enhanced NEP enzymatic activity and clearance of Aβ in APP/PS1 transgenic mice. Thus, we propose that G-CSF may be a possible therapeutic strategy against AD.

    Alzheimer's disease is a progressive neurodegenerative disorder. Amyloid β, a neurotoxic protein, causes disruption of hippocampal synaptic plasticity, and induces cognitive impairment in Alzheimer's disease. We previously revealed that fingolimod, a new oral immunosuppressant used to treat multiple sclerosis, ameliorates oligomeric amyloid β-induced neuronal damage via up-regulation of neuronal brain-derived neurotrophic factor (BDNF). Here, we showed that oral administration of fingolimod ameliorated the impairment in object recognition memory and associative learning in mice injected with amyloid β. This effect was associated with restoration of normal BDNF expression levels in the cerebral cortices and hippocampi, suggesting that neuroprotection was mediated by up-regulation of neuronal BDNF levels. Therefore, fingolimod may provide therapeutic effects in patients with Alzheimer's disease.

    Interferon-induced transmembrane protein 3 (IFITM3) ıplays a crucial role in the antiviral responses of Type I interferons (IFNs). The role of IFITM3 in the central nervous system (CNS) is, however, largely unknown, despite the fact that its expression is increased in the brains of patients with neurologic and neuropsychiatric diseases. Here, we show the role of IFITM3 in long-lasting neuronal impairments in mice following polyriboinosinic-polyribocytidylic acid (polyI:C, a synthetic double-stranded RNA)-induced immune challenge during the early stages of development. We found that the induction of IFITM3 expression in the brain of mice treated with polyI:C was observed only in astrocytes. Cultured astrocytes were activated by polyI:C treatment, leading to an increase in the mRNA levels of inflammatory cytokines as well as Ifitm3. When cultured neurons were treated with the conditioned medium of polyI:C-treated astrocytes (polyI:C-ACM), neurite development was impaired. These polyI:C-ACM-induced neurodevelopmental abnormalities were alleviated by ifitm3(-/-) astrocyte-conditioned medium. Furthermore, decreases of MAP2 expression, spine density, and dendrite complexity in the frontal cortex as well as memory impairment were evident in polyI:C-treated wild-type mice, but such neuronal impairments were not observed in ifitm3(-) (/) (-) mice. We also found that IFITM3 proteins were localized to the early endosomes of astrocytes following polyI:C treatment and reduced endocytic activity. These findings suggest that the induction of IFITM3 expression in astrocytes by the activation of the innate immune system during the early stages of development has non-cell autonomous effects that affect subsequent neurodevelopment, leading to neuropathological impairments and brain dysfunction, by impairing endocytosis in astrocytes.

    Matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs) remodel the pericellular environment by regulating the cleavage of extracellular matrix proteins, cell surface components, neurotransmitter receptors, and growth factors, which together regulate cell adhesion, synaptogenesis, synaptic plasticity, and long-term potentiation. Increased MMP activity and dysregulation of the balance between MMPs and TIMPs have also been implicated in various pathological conditions. Recent studies have suggested that prolonged seizures are associated with high MMP levels in serum and neural tissues, and certain extracellular macromolecule targets may influence the pathogenesis of epilepsy and seizure. In this review, we discuss the roles of MMP activation in animal models of epilepsy.

    The cholinesterase inhibitor, rivastigmine, ameliorates cognitive dysfunction and is approved for the treatment of Alzheimer's disease (AD). Rivastigmine is a dual inhibitor of acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE); however, the impact of BuChE inhibition on cognitive dysfunction remains to be determined. We compared the effects of a selective BuChE inhibitor, N1-phenethyl-norcymserine (PEC), rivastigmine and donepezil (an AChE-selective inhibitor) on cognitive dysfunction induced by amyloid-β peptide (Aβ(1-40)) in mice. Five-week-old imprinting control region (ICR) mice were injected intracerebroventricularly (i.c.v.) with either Aβ(1-40) or the control peptide Aβ(40-1) on Day 0, and their recognition memory was analyzed by a novel object recognition test. Treatment with donepezil (1.0mg/kg), rivastigmine (0.03, 0.1, 0.3mg/kg) or PEC (1.0, 3.0mg/kg) 20min prior to, or immediately after the acquisition session (Day 4) ameliorated the Aβ(1-40) induced memory impairment, indicating a beneficial effect on memory acquisition and consolidation. In contrast, none of the investigated drugs proved effective when administrated before the retention session (Day 5). Repeated daily administration of donepezil, rivastigmine or PEC, on Days 0-3 inclusively, ameliorated the cognitive dysfunction in Aβ(1-40) challenged mice. Consistent with the reversal of memory impairments, donepezil, rivastigmine or PEC treatment significantly reduced Aβ(1-40) induced tyrosine nitration of hippocampal proteins, a marker of oxidative damage. These results indicate that BuChE inhibition, as well as AChE inhibition, is a viable therapeutic strategy for cognitive dysfunction in AD.

    Several clinical studies have demonstrated a consistent relationship between changes in meteorological factors, particularly barometric pressure, and pain intensity in subjects with chronic pain. We have previously demonstrated that exposure to artificially low barometric pressure (LP) intensifies pain-related behaviors in rats with neuropathic pain. In the present study, guinea pigs with unilateral L5 spinal nerve ligation (SNL) were placed in a pressure-controlled chamber and subjected to LP of 10 or 27hPa below the ambient pressure. The SNL surgery led to increased hindpaw withdrawal frequencies to 34-, 59-, and 239-mN von Frey filaments (VFFs). When the SNL animals were subjected to both LP exposures consecutively, the hindpaw withdrawal frequencies further increased; the effect was most significant when the animals were exposed to LP 27hPa below ambient pressure. In contrast, no change was seen in a group of sham-operated control animals. These results indicate that fluctuations in LP within the range of natural weather patterns can potentiate neuropathic pain in guinea pigs.

    AIM:To examine the effect of irsogladine, a novel antiulcer drug, on the mucosal ulcerogenic response to monochloramine (NH(2)Cl) in rat stomach, in comparison with rebamipide, another antiulcer drug with cytoprotective a ctivity.METHODS AND RESULTS:Oral administration of NH(2)Cl-(120mM) produced severe hemorrhagic lesions in unanesthetized rat stomachs.Both irsogladine (1mg/kg-10mg/ kg,po) and rebamipide (30mg/kg-100mg/kg, po) dose dependently prevented the development of these lesions in response to NH(2)Cl, the effect of irsogladine was significant at 3mg/kg or greater, and that of rebamipide only at 100mg/kg. The protective effect of irsogladine on NH(2)Cl induced gastric lesions was significantly reduced by N( G) nitro L arginine methyl ester (L-NAME) but not by indomethacin, while that of rebamipide was significantly mitigated by indomethacin but not by L-NAME. Topical application of NH(2)Cl-(20mM)caused a marked reduction of potential difference (PD) in exvivo stomachs. This PD reduction was not affected by mucosal application of irso-gladine, but significantly prevented by rebamipide. The mucosal exposure to NH(4)OH (120mM) also caused a marked PD reduction in the ischemic stomach (bleeding from the carotid artery), resulting in gastric lesions. These ulcerogenic and PD responses caused by NH(4)OH plus ischemia were also significantly mitigated by rebamipide, in an indomethacin sensitive manner, while irsogladine potently prevented such lesions without affecting the PD response, in a L-NAME sensitive manner.CONCLUSION:These results suggest that (1)NH(2)Cl gen-erated either exogenously or endogenously damages the gastric mucosa, (2)both irsogladine and rebamipide protect the stomach against injury caused by NH(2)Cl,and (3)the mechanism underlying the protective action of irsogladine is partly mediated by endogenous nitric oxide, while that of rebamipide is in part mediated by endogenous prostaglandins.

    Psychological stresses such as social loss and separation during childhood induce hardship, referred to as emotional pain. These experiences are well-documented risk factors for the development of physical pain in adulthood. However, the underlying neuronal mechanisms of this exacerbation of pain are largely unknown, and consequently there is no effective pharmacotherapy. In this study, we sought to determine whether infant maternal separation (MS) contributes to aggravation of neuropathic pain in adult mice. MS increased anxiety- and depression-like behavioral responses to adult stress. In MS animals, chronic constriction injury (CCI) heightened the sensory dimension of chronic pain relative to that of control mice. However, MS mice treated with fluoxetine for 4 weeks after MS did not exhibit augmentation of allodynia, and their emotional response was attenuated. Microglia were more abundant in the spinal cord in MS/CCI mice than in control/CCI mice. These results suggest that emotional impairment is related to augmentation of neuropathic pain, and that dysfunction of microglial activation contributes to heightened pain sensitivity.

    Patients suffering from neuropsychiatric disorders such as substance use and addiction disorders show impaired decision-making, which may be associated with their psychiatric disorders. Previously, using a gambling test for rodents, we demonstrated that methamphetamine-dependent rats showed alterations in their decision-making strategy. In this study, we investigated the effect of nicotine on impaired decision-making strategy in rats which have been treated repeatedly with methamphetamine. Nicotine has previously been shown to have therapeutic effects on attentional and cognitive abnormalities in psychosis. Rats were administered methamphetamine subcutaneously (sc) at 4 mg/kg once a day, for 30 days, and their decision-making was then assessed with a rodent gambling task. We found that methamphetamine-treated rats preferred the high-risk/high-return actions, which is consistent with our previous findings. Methamphetamine-induced impairment of decision-making was reversed by daily nicotine treatment (0.3 mg/kg, sc). This effect was associated with the reduction of lose-shift behavior after negative reward prediction error. Repeated treatment with nicotine had no effects on arm-choice behavior in naïve rats. Varenicline, an α4β2-nicotinic acetylcholine receptor partial agonist, also ameliorated the altered decision-making in methamphetamine-treated rats. Our findings suggest that nicotine treatment is useful for ameliorating the altered decision-making caused by methamphetamine treatment, and that the α4β2-nicotinic acetylcholine receptor is a therapeutic target for poor decision-making.

    Patients suffering from neuropsychiatric disorders such as substance-related and addictive disorders exhibit altered decision-making patterns, which may be associated with their behavioral abnormalities. However, the neuronal mechanisms underlying such impairments are largely unknown. Using a gambling test, we demonstrated that methamphetamine (METH)-treated rats chose a high-risk/high-reward option more frequently and assigned higher value to high returns than control rats, suggestive of changes in decision-making choice strategy. Immunohistochemical analysis following the gambling test revealed aberrant activation of the insular cortex (INS) and nucleus accumbens in METH-treated animals. Pharmacological studies, together with in vivo microdialysis, showed that the insular neural system played a crucial role in decision-making. Moreover, manipulation of INS activation using designer receptor exclusively activated by designer drug technology resulted in alterations to decision-making. Our findings suggest that the INS is a critical region involved in decision-making and that insular neural dysfunction results in risk-taking behaviors associated with altered decision-making.

    意思決定に必要な習慣的システムと目的指向的システムは連続的、並列的な関係で、どちらかの能力が劣っているわけでもない。げっ歯類の脳内でのシステム間連係を計算論的に表現できれば、高次脳機能の理解に繋がるものの、基礎研究において、システム間バランスに注目した意思決定研究は少ない。また、システム間バランス異常に関与する責任脳領域は不明であり、それを打破する策として、精神疾患モデル動物を用いることで、明らかになると考える。本研究では、ギャンブル障害モデル動物を用いて、意思決定システム間バランスを評価する行動試験の開発・発展と情報処理システムの解明に挑戦する。
    意思決定を行うには、習慣的システムと目的指向的システムが状況に応じて切り替わりながら、協調的に働くことが必要である。これら情報処理システムの協調的バランスに問題が生じると、自己制御能力の低下や近視眼的意思決定に繋がる。意思決定に異常があると言われている精神疾患に依存症がある。依存症の中で社会的且つ医薬学的対策が急務なのはギャンブル障害であるが、ギャンブル障害において情報処理システム間のバランス破綻に着目した報告は少ない。本研究では、①げっ歯類を対象とした情報処理システムを評価する新規行動試験の開発・発展、②モデルフィットによる情報処理システム間のバランス異常を示すパラメータ推定、③ギャンブル障害関連遺伝子の情報処理システムへの影響から、意思決定システム間バランスを評価する行動試験の開発・発展と情報処理システムの解明に挑戦する。初年度はDRD2-Creラットを用いて、選択的な間接路機能を調節できるか確認した。AAV-FLEX-DTAをDRD2-Creラットの側坐核領域にインジェクションすると、DRD2陽性細胞が減少することを免疫組織学的検討により明らかにした。このことから、間接路特異的な神経脱落を誘導できることが分かった。また、このラットの体重もコントロール群と比較して大きく変動しなかった。さらに、間接路の特異的な遺伝子をノックダウン、特にDRD2をノックダウンさせるため、CRISPR/Cas9システムを導入し、in vitro実験に着手した。
    行動実験に少し遅れがでている。
    今年度は、意思決定システム間バランスを評価する行動試験の開発とギャンブル障害関連遺伝子の機能的役割の解明に挑戦するため、以下の実験を行う。
    実験1:臨床研究を反映させたげっ歯類の情報処理システムを評価する行動試験を開発・発展させる。
    実験2:モデルフィット化による情報処理システム間のバランス異常を示すパラメータを推定する。Weighting parameter(システム間比重)、学習係数(更新度合)、逆温度(選択のランダム性)、perseveration (反復性)などのパラメータを抽出する。

    依存症は健康を脅かす疾患であり、ギャンブル障害、ゲーム障害などが新たに精神疾患として認定されるなど、今まで以上に身近な社会問題として懸念されている。この事から新たな依存症の包括的理解に向けた機序解明が必要である。本研究では、多種多様な遺伝子発現制御法と遺伝子改変ラットを用いて、島皮質を基軸とした意思決定・行動選択の変容に関わる領域間ネットワーク、神経-神経ネットワークを解明し、依存症の新たな治療戦略の発信を目指す。
    依存症は世界銀行・WHOが報告するDALY(障害調整生命年)によると、世界トップ10に入る健康を脅かす疾患であり、ギャンブル障害、ゲーム障害などが新たに精神疾患として認定されるなど、今まで以上に身近な社会問題として懸念されている。申請者は、依存症の完治困難な原因に意思決定異常があることから、依存症抑止に向けたリスク志向な意思決定の解明を志し、島皮質がリスク志向な意思決定のハブ領域である可能性を見つけた。
    本研究では、多種多様な遺伝子発現制御法と遺伝子改変ラットを用いて、島皮質を基軸とした意思決定・行動選択の変容に関わる領域間ネットワーク、神経-神経ネットワークを解明する。ラットの意思決定の解析は、ラット用ギャンブル試験を使用する(PNAS, 2015; Behav Brain Res, 2019)。この解析手法を用いると正常動物は、リスク回避行動を示すことが分かっている。初年度は、DRD2-Creラットを用いて間接路の神経脱落がリスク回避行動を促す可能性について例数を追加し、結論を得た。さらに、新規逆行性rAAV-Flp(FLP/FRTシステム)を用いると経路特異的に遺伝子を発現させることができることを免疫組織学的検討により確認した。また、DRD2-CreラットとRosa-tdTomatoラットとを交配させ、間接路特異的にtdTomatoが発現するラットを作製した。このラットを用いて、島皮質から入力する信号が間接路にどのような影響を及ぼすか、電気生理学的セットアップを行った。また、間接路特異的な遺伝子発現をコントロールするため、新たにCRISPR/Cas9システムの導入に向けたプロジェクトを発足させ、in vitroレベルでの構築を始めた。
    細胞活動の操作手技の確認、準備は終えているが、行動実験に着手できていない。
    今年度は昨年度より続けてきた電気生理学的手法を用いて、島皮質-線条体神経の活動のみを光遺伝学的手法により操作したときの、間接路、直接路への影響を検討する。さらに、逆行性rAAV-Flpを用いて、島皮質-線条体経路特異的にDREADDを発現させ、このラットを用いてギャンブル試験を行う。また、CRISPR/Cas9システムを構築し、間接路上の受容体を特異的にノックダウンさせることに挑戦する。

    「意志力」は自己をコントロールし、難局を打開するのに必要な力である。意志力を強化することは、ストレス社会を生き抜く術である。我々は以前に、オレキシン神経の活性化は諦めない行動(意志力)に関わることを見つけ、自己コントロールにおけるオレキシン神経系の機能的役割を行動学的に明らかにした。しかし、①意志力検証実験中オレキシン神経は活性化しているのか、②課題遂行中のどのタイミングのオレキシン神経活動が、課題成功率にかかわるのかは不明である。そこで本研究では光遺伝学的手法を導入し、オレキシン神経活動の測定と、操作した時の報酬動機づけ行動への影響を検討する。
    「意志力」は自己をコントロールし、難局を打開するのに必要な力である。我々は、オレキシン神経の活性化は報酬獲得に対するモチベーションの増加(諦めない行動)や確率逆転学習の成功率の低下に関わることを見つけ、自己コントロールにおけるオレキシン神経系の機能的役割を行動学的に実証した。しかし、①意志力検証実験中オレキシン神経は活性化しているのか、②課題遂行中のどのタイミングのオレキシン神経活動が、課題成功率にかかわるのかは不明である。本研究では、光遺伝学的手法を導入し、オレキシン神経活動の測定と、操作した時の意志力行動への影響を検討する。タッチスクリーン式弁別試験を用いて、意志力による自己コントロールにおけるオレキシン神経の機能的役割について検討する。初年度は、progressive ratio試験においてオレキシン神経を脱落させると、有意なやる気行動の低下が認められたが、メチルフェニデートを投与すると、緩解する傾向があることが分かった。また、orexin-CreラットにAAV-FLEX-ChR2をインジェクションし、ChR2を強制発現させたところ、ChR2の細胞特異的な発現局在が確認でき、視床下部を光刺激すると覚醒することを確認した。このことから、光刺激によってオレキシン神経を操作できることが分かった。新たに神経活動をin vivoで測定する装置(ワイヤレスファイバーフォトメトリー)を導入した。予備検討段階であるが、エアパフ刺激によるオレキシン神経活動をとらえることができた。
    多少の実験の失敗はあるが、代替案により進んでいる。
    タッチスクリーン式弁別試験を用いて、意志力による自己コントロールにおけるオレキシン神経の機能的役割について検討する。今回はprogressive ratio試験と確率逆転学習課題を行わせる。今年度特に、orexin-CreラットにAAV-FLEX-ChR2をインジェクションし、ChR2を強制発現させたラットを用いて、オレキシン神経活動を操作し、動機づけ行動がどのように変化するか検討する。また、強化学習モデルに当てはめ、動機づけ行動の意味付けを行う。さらに、新たに神経活動をin vivoで測定する装置(ワイヤレスファイバーフォトメトリー)を導入したので、その機器を用いて動機づけ行動時におけるオレキシン神経活動を測定する。予備検討段階であるが、エアパフ刺激によるオレキシン神経活動をとらえている。

    報酬に対する動機づけとしてギャンブル試験を、課題に対する動機づけとしてタッチスクリーン式弁別試験を用いることで、意志力を検証できるシステムを構築した。また、orexin BAC-Creラットを用いて、オレキシン神経特異的にDesigner Receptors Exclusively Activated by Designer Drugs (DREADD)を発現させ、動機づけ行動におけるオレキシン神経の役割を明らかにしてきた。
    特に平成30年度は、オレキシン神経の活性化は諦めない行動や確率逆転学習にも影響することを見つけ、課題に対する動機づけ行動に影響を及ぼすことが分かった。また、ギャンブル試験の行動データを計算論モデリングしたところ、オレキシン神経を活性化させるとハイリターンに対する期待値が高くなることが分かった。これらの事から、オレキシン神経はやる気・意志力に関わる神経回路の一旦を担う可能性が示され、特に、オレキシン神経は不確実な状況下における報酬に対する期待値に影響を及ぼす可能性があることが分かった。また、オレキシン神経の活性化は摂食量、摂水量を増加させることが分かった。しかし、行動量については影響なかった。これらの結果から、オレキシン神経の活性化は既報と同じように本能行動に影響することが示された。また、現在検討中であるが、蛍光イメージングシステム(ファイバーフォトメトリー)を用いて、動機づけにおけるオレキシン神経活動を測定し、オレキシン神経を光操作したときの動機づけ行動について検討している。このイメージング実験についてはシステムの工夫が必要であると考えている。

    Decision-making is a key activity process that influences many aspects of daily living and both mental and physical health. In general, healthy participants reveal rational choice, but patients with neuropsychiatric disorders reveal irrational and risky choice in decision-making. A better understanding of the mechanisms underlying altered decision-making would provide insights into potential therapeutic approaches for these diseases. However, the neural pathway and substrates underlying these deficits are particularly unknown. In this research, we demonstrated that insular cortex, nucleus accumbens, and striatum are key regions for risky decision-making. Our findings suggest that disinhibition of glutamatergic neurons as well as dysfunction of GABAergic interneurons in the insular cortex, plays a role in altered decision-making. Further research on the insular-striatal pathway would be necessary to understand the mechanisms underlying impaired decision-making.

    Decision-making and reinforcement learning arise from the involvement of two distinct processes that control choice, known as model-based and model-free strategies. Model-based choices are prospective, whereas model-free choices are retrospective. In general, normal performance depends on the flexible integration of model-based and model-free control. In this research, we employed a two-step sequential visual discrimination learning of complex stimuli in touch-screen task to establish a novel behavioral system for investigating a mixture of model-free and model-based reinforcement learning in rodent. Rats chose option on the reward amount- and provability-dependent manner. However, we failed to find best fitting behavioral modeling and parameters. We need to continue our experiments in future studies.

    Patients suffering from neuropsychiatric disorders such as substance-related and addictive disorders have impairments in decision-making, which may be associated with their behavioral abnormalities. However, the neuronal mechanisms underlying such impairments are largely unknown. Using a gambling test, we demonstrated that methamphetamine (METH)-dependent rats choose a high-risk/high-reward option more frequently, and assign higher subjective value to high returns, than control rats, suggesting that decision-making is impaired in the drug-dependent animals. Immunohistochemical analysis following the gambling test revealed aberrant activation of the insular cortex (INS) and nucleus accumbens in METH-dependent animals. Pharmacological studies together with in vivo microdialysis showed that GABAergic neurotransmission in INS played a crucial role in decision-making. Moreover, manipulation of INS activation using DREADD technology resulted in alterations to decision-making.

    精神病患者にみられる意思決定(実行機能など)の障害は生体ホメオスタシスの制御機構の変化 (Science, 2007)、近い将来の快感に関連する扁桃体を含む衝動的神経回路と遠い将来に関係する思慮的な前頭葉皮質回路のアンバランス (Nat Neurosci, 2005) に基づくと提唱されているが、意思決定障害の研究は他の精神異常と比べて明らかに遅れている。それゆえ、この分野の小動物を用いた研究の発展は、意思決定異常時における脳内プロセスの解明に大きな研究成果を残し、さらには、精神疾患患者を対象とした臨床応用研究・治療などの方向性を明確に定めると期待できる。昨年度は、島皮質をDREADDテクノロジーで操作することで、意思決定・行動選択を操作出来ることを確認し、さらには、覚せい剤誘発意思決定障害について、計算論的手法を用いて、モデル化することができた。今年度は、意思決定における大脳基底核の直接路、間接路の役割について検討した。その結果、直接路をDREADDテクノロジーで活性化させると、リスク志向な意思決定を示すことが分かった。また、計算論的手法を用いて、その行動選択をモデル化したところ、その行動は探索的である可能性が示されたが、この点については詳細な検討が必要である。一方、間接路を活性化させても行動選択に影響はなかった。この点についても遺伝子の発現量やウイルスベクターの選択性による影響が大きいことから、詳細な検討が必要と考えている。

    In this study, we examined the effects of nicotine on reward-based decision-making in healthy and methamphetamine (METH)-treated rat. We analyzed the performance of rats in a gambling test for rodents. Nicotine treatment (0.3 mg/kg) ameliorated the abnormal arm-choice behavior of METH-treated rats in the gambling test. However, chronic nicotine treatment (0.3 or 0.6 mg/kg) did not show changes in arm-choice behavior in healthy rats. Our findings suggest that nicotine may have some therapeutic effects against impairment of decision-making in METH addicts.
