    English, Scientific journal, Idiopathic hypersomnia (IH) is a sleep disorder characterised by excessive daytime sleepiness despite adequate night-time sleep. Although current treatments, including low-sodium oxybate and modafinil, are readily available for IH, they are associated with side effects such as drug dependence and abuse. Histamine, a key neurotransmitter, plays a critical role in promoting wakefulness and reducing the risk of drug dependence. Clinical studies have found reduced histamine levels in the cerebrospinal fluid of patients with hypersomnia, suggesting that enhanced histaminergic neurotransmission could alleviate IH symptoms. In our recent study, we demonstrated that the pharmacological inhibition of histamine N-methyltransferase (HNMT), the enzyme responsible for histamine degradation, significantly increased brain histamine levels and improved hypersomnolence and sleep attacks in a mouse model of narcolepsy. Based on these findings, we hypothesised that HNMT inhibitors could serve as novel therapeutic agents for IH treatment. In this study, we examined the effects of metoprine, a potent HNMT inhibitor, on sleep-wake behaviour in Sik3Sleepy mutant mice, a mouse model of IH. Our results show that metoprine significantly increased brain histamine levels without altering dopamine, norepinephrine, or serotonin levels. Sleep analysis revealed that metoprine markedly promoted wakefulness and prolonged sleep latency, likely through the activation of the histamine receptor H1. Furthermore, the wake-up promoting effect of metoprine was more pronounced than that of other agents, including a histamine receptor H3 inverse agonist and an orexin receptor agonist. These findings suggest that the pharmacological inhibition of HNMT represents a promising therapeutic strategy for IH.

    Scientific journal, Abstract

    Histamine, a neurotransmitter, plays a predominant role in maintaining wakefulness. Further, our previous studies showed that histamine N-methyltransferase (HNMT), a histamine-metabolising enzyme, is important for regulating brain histamine concentration. However, the effects of pharmacological HNMT inhibition on mouse behaviour, including the sleep-wake cycle and cataplexy, in a mouse model of narcolepsy have not yet been investigated. In the present study, we investigated the effects of metoprine, an HNMT inhibitor with high blood-brain barrier permeability, in wild-type (WT) and orexin-deficient (OxKO) narcoleptic mice. Metoprine increased brain histamine concentration in a time- and dose-dependent manner without affecting peripheral histamine concentrations. Behavioural tests showed that metoprine increased locomotor activity in both novel and familiar environments, but did not alter anxiety-like behaviour. Sleep analysis showed that metoprine increased wakefulness and decreased non-rapid eye movement (NREM) sleep through the activation of the histamine H1 receptor (H1R) in WT mice. In contrast, the reduction of rapid eye movement (REM) sleep by metoprine occurred independent of H1R. In OxKO mice, metoprine was found to prolong wakefulness and robustly suppress cataplexy. In addition, metoprine has a greater therapeutic effect on cataplexy than pitolisant, which induces histamine release in the brain, and has been approved for patients with narcolepsy. These data demonstrate that HNMT inhibition has a strong effect on wakefulness, demonstrating therapeutic potential against cataplexy in narcolepsy.

    English, Scientific journal, PURPOSE: Noninvasive imaging of protein aggregates in the brain is critical for the early diagnosis, disease monitoring, and evaluation of the effectiveness of novel therapies for Alzheimer's disease (AD). Near-infrared fluorescence (NIRF) imaging with specific probes is a promising technique for the in vivo detection of protein deposits without radiation exposure. Comprehensive screening of fluorescent compounds identified a novel compound, THK-565, for the in vivo imaging of amyloid-β (Aβ) deposits in the mouse brain. This study assessed whether THK-565 could detect amyloid-β deposits in vivo in the AD mouse model. PROCEDURES: The fluorescent properties of THK-565 were evaluated in the presence and absence of Aβ fibrils. APP knock-in (APP-KI) mice were used as an animal model of AD. In vivo NIRF images were acquired after the intravenous administration of THK-565 and THK-265 in mice. The binding selectivity of THK-565 to Aβ was evaluated using brain slices obtained from these mouse models. RESULTS: The fluorescence intensity of the THK-565 solution substantially increased by mixing with Aβ fibrils. The maximum emission wavelength of the complex of THK-565 and Aβ fibrils was 704 nm, which was within the optical window range. THK-565 selectively bound to amyloid deposits in brain sections of APP-KI mice After the intravenous administration of THK-565, the fluorescence signal in the head of APP-KI mice was significantly higher than that of wild-type mice and higher than that after administration of THK-265. Ex vivo analysis confirmed that the THK-565 signal corresponded to Aβ immunostaining in the brain sections of these mice. CONCLUSIONS: A novel NIRF probe, THK-565, enabled the in vivo detection of Aβ deposits in the brains of the AD mouse model, suggesting that NIRF imaging with THK-565 could non-invasively assess disease-specific pathology in AD.

    English, Scientific journal, Quantification of in vivo reactive astrogliosis, which represents neural inflammation and remodeling in the brain, is an emerging methodology for the evaluation of patients with neurodegenerative diseases. [18F]THK-5351 is a positron emission tomography (PET) tracer for monoamine oxidase B (MAO-B), a molecular marker of reactive astrogliosis. We performed in vivo [18F]THK-5351 PET in a patient who at autopsy was found to have argyrophilic grain disease (AGD) with comorbid pathology to visualize reactive astrogliosis for the first time. We aimed to validate an imaging-pathology correlation using [18F]THK-5351 PET and the autopsy brain. The patient, a 78-year-old man, was pathologically diagnosed with AGD combined with limbic-predominant age-related transactive response DNA-binding protein of 43 kDa encephalopathy and Lewy body disease without Alzheimer disease-related neuropathological changes. Reactive astrogliosis in the postmortem brain was abundant in the inferior temporal gyrus, insular gyrus, entorhinal cortex, and ambient gyrus where premortem [18F]THK-5351 signals were high. We found a proportional correlation between the amount of reactive astrogliosis in the postmortem brain and the in vivo [18F]THK-5351 standardized uptake value ratio (r = 0.8535, p = 0.0004). These results indicated that reactive astrogliosis in AGD with comorbid pathology could be identified and quantified by in vivo MAO-B imaging.

    English, Scientific journal, Histamine is synthesised from l-histidine through the catalysis of histidine decarboxylase (HDC). In the central nervous system (CNS), histamine is exclusively produced in histaminergic neurons located in the posterior hypothalamus and controls various CNS functions. Although histidine was known as a precursor of histamine, the impact of oral histidine intake on brain histamine concentration and brain function has not been fully elucidated. In the present study, we aimed to elucidate the importance of oral histidine supplementation in the histaminergic nervous system and working memory in stressful conditions. First, we confirmed that sleep deprivation by water-floor stress in male mice increased histamine consumption and resulted in histamine reduction and impaired working memory in the Y-maze test. This memory impairment was rescued by intracerebroventricular injection of histamine and histidine, indicating that oral histidine intake could also improve memory function. Next, we examined the impact of histidine intake on brain histamine concentration and neuronal activity. Histidine intake increased extracellular histamine concentration around the prefrontal cortex (PFC) and the basal forebrain (BF), leading to a robust increase in the number of c-fos-positive cells around these areas. Finally, we investigated the beneficial effects of histidine intake on working memory. Histidine supplementation alleviated impaired memory function induced by sleep deprivation. This beneficial effect of histidine on memory was cancelled by intracerebroventricular injection of the HDC inhibitor α-fluoromethylhistidine. These results demonstrate that oral histidine intake replenishes brain histamine and leads to the recovery of impaired working memory induced by sleep deprivation through histaminergic activation.

    English, Scientific journal, Brain histamine acts as a neurotransmitter in the regulation of various brain activities. Previous studies have shown that histamine N-methyltransferase (HNMT), a histamine-metabolizing enzyme, controls brain histamine concentration and brain function. However, the relative contribution of astrocytic or neuronal HNMT to the regulation of the histaminergic system is still inconclusive. Here, we phenotyped astrocytes-specific HNMT knockout (cKO) mice to clarify the involvement of astrocytic HNMT in histamine clearance and brain function. First, we performed histological examinations using HNMT reporter mice and showed a wide distribution of HNMT in the brain and astrocytic HNMT expression. Then, we created cKO mice by Cre-loxP system and confirmed that HNMT expression in cKO primary astrocytes was robustly decreased. Although total HNMT level in the cortex was not substantially different between control and cKO brains, histamine concentration after histamine release was elevated in cKO cortex. In behavioral tests, impaired motor coordination and lower locomotor activity were observed in the cKO mice. However, anxiety-like behaviors, depression-like behaviors, and memory functions were not altered by astrocytic HNMT disruption. Although sleep analysis demonstrated that the quantity of wakefulness and sleep did not change, the increased power density of delta frequency during wakefulness indicated lower cortical activation in cKO mice. These results demonstrate that astrocytic HNMT contributes to histamine clearance after histamine release in the cortex and plays a role in the regulation of motor coordination, locomotor activity, and vigilance state.

    English, Scientific journal, Histamine acts as a neurotransmitter in the central nervous system and is involved in numerous physiological functions. Recent studies have identified the causative role of decreased histaminergic systems in various neurological disorders. Thus, the brain histamine system has attracted attention as a therapeutic target to improve brain function. Neurotransmitter clearance is one of the most important processes for the regulation of neuronal activity and is an essential target for diverse drugs. Our previous study has shown the importance of histamine N-methyltransferase for the inactivation of brain histamine and the intracellular localization of this enzyme; the study indicated that the transport system for the movement of positively charged histamine from the extracellular to intracellular space is a prerequisite for histamine inactivation. Several studies on in vitro astrocytic histamine transport have indicated the contribution of organic cation transporter 3 (OCT3) and plasma membrane monoamine transporter (PMAT) in histamine uptake, although the importance of these transporters in in vivo histamine clearance remains unknown. Immunohistochemical analyses have revealed the expression of OCT3 and PMAT on neurons, emphasizing the importance of investigating neuronal histamine uptake. Further studies using knockout mice or fast-scan cyclic voltammetry will accelerate the research on histamine transporters. In this review article, we summarize histamine transport assays and describe the candidate transporters responsible for histamine transport in the brain.

    English, Scientific journal, The lateral hypothalamus contains neurons producing orexins that promote wakefulness and suppress REM sleep as well as neurons producing melanin-concentrating hormone (MCH) that likely promote REM sleep. Narcolepsy with cataplexy is caused by selective loss of the orexin neurons, and the MCH neurons appear unaffected. As the orexin and MCH systems exert opposing effects on REM sleep, we hypothesized that imbalance in this REM sleep-regulating system due to activity in the MCH neurons may contribute to the striking REM sleep dysfunction characteristic of narcolepsy. To test this hypothesis, we chemogenetically activated the MCH neurons and pharmacologically blocked MCH signaling in a murine model of narcolepsy and studied the effects on sleep-wake behavior and cataplexy. To chemoactivate MCH neurons, we injected an adeno-associated viral vector containing the hM3Dq stimulatory DREADD into the lateral hypothalamus of orexin null mice that also express Cre recombinase in the MCH neurons (MCH-Cre::OX-KO mice) and into control MCH-Cre mice with normal orexin expression. In both lines of mice, activation of MCH neurons by clozapine-N-oxide (CNO) increased rapid eye movement (REM) sleep without altering other states. In mice lacking orexins, activation of the MCH neurons also increased abnormal intrusions of REM sleep manifest as cataplexy and short latency transitions into REM sleep (SLREM). Conversely, a MCH receptor 1 antagonist, SNAP 94847, almost completely eliminated SLREM and cataplexy in OX-KO mice. These findings affirm that MCH neurons promote REM sleep under normal circumstances, and their activity in mice lacking orexins likely triggers abnormal intrusions of REM sleep into non-REM sleep and wake, resulting in the SLREM and cataplexy characteristic of narcolepsy.

    Neurotensin works as a neuropeptide in the brain. We have reported that experimental stimulation of neurotensinergic neurons in the lateral hypothalamus (Nts-LH) caused hyperarousal in mice. However, it remains unclear whether Nts-LH is involved in the physiological sleep-wake cycle. Thus, in the present study, we investigated the effect of Nts-LH selective lesion on physiological sleep-wake cycle. We also measured neuronal activities of Nts-LH during sleep and wakefulness. First, we performed Nts-LH lesion induced by diphtheria toxin-A. The Nts-LH lesion caused a fragmentation of wakefulness and decreased total amount of wakefulness, implying that Nts-LH was critical in the transition and maintenance of wakefulness. Next, we measured the neuronal activities of Nts-LH during sleep and wakefulness by using fiber photometory with a Ca2+ sensor, GCaMP7f. The calcium imaging clearly showed that Nts-LH was simultaneously activated at the transition from sleep to wakefulness, followed by continuous excitation during wakefulness. These data emphasize that Nts-LH mediate sleep-to-wake transition then their activation promote the following wakefulness. Taken together, the neuronal activity of Nts-LH maintains wakefulness, which is important for physiological sleep-wake cycles, Japanese Pharmacological Society, Japanese
  • Assessment of learning achievement using self-assessment rubric in the role-play for pharmacological education.
    Nakamura Tadaho, Kimura Takeshi, Naganuma Fumito, Yoshikawa Takeo, Okamura Nobuyuki, Yanagita Toshihiko, Proceedings for Annual Meeting of The Japanese Pharmacological Society, 96, 4-B-O13-6, 2022
    Background. The role-play for pharmacological education (RPPE) provides a practical training focused on the basis of drug therapy. Learning achievement in RPPE, however, has not been researched precisely. In this study, we assessed the learning achievement in RPPE by using a self-assessment rubric.

    Methods. Participants: Fourth grade medical students at Tohoku Medical and Pharmaceutical University who took the online RPPE (oRPPE) in 2022. Measurements: Self-assessment rubric was presented to participants on the first day of the course. Four following categories were scored on a five-point scale: I) Understanding: a. health problems of the case in charge; b. drug therapy of the case in charge; c. role-play performed by the others, II) Preparation, III) Performance and IV) Discussion and dialogue. Students were directed to assess themselves during preparation and performance of oRPPE. Data collection and analysis: Scores were collected after course completion. All data are presented as the mean ± standard error of the mean (S.E.M.).

    Results. The self-assessment showed high scores in the following 3 categories: I) Understanding (a. 4.10 ± 0.06; b. 4.10 ± 0.06; c. 3.94 ± 0.07), II) Preparation (4.32 ± 0.06) and III) Performance (4.21 ± 0.07). These results indicate that RPPE could provide basic practice for drug therapy. It also implies that specification of expected outcomes through rubric beforehand might be useful to guide self- and peer-learning during preparation and performance. On the other hand, the score in IV) Discussion and dialogue (3.75 ± 0.09) might reflect difficulties to discuss the whole process of clinical practice in each case, which requires advanced professional competencies.

    Conclusion. The self-assessment rubric is a useful tool for assessing achievement of learning in RPPE., Japanese Pharmacological Society, Japanese

  • Learning outcomes of the online role-play for pharmacological education: comparison between players and audiences
    Nakamura Tadaho, Naganumra Fumito, Okamura Nobuyuki, Yanagita Toshihiko, Proceedings for Annual Meeting of The Japanese Pharmacological Society, 95, 2-O-060, 2022
    Background: The goal of the role-play for pharmacological education (RPPE) is to acquire fundamental competences for drug therapy. These competences are based on presentation and communication skills as well as understanding of pharmacology and pathophysiology. The conventional face-to-face RPPE exhibited much higher learning effects in players than audiences, although audiences also established efficient learning through observation and discussion. However, the learning outcomes of the online RPPE (oRPPE) has not been determined. In this study, we evaluated oRPPE learning effects.

    Methods: Participants: 4th grade medical student at Tohoku Medical and Pharmaceutical University who took oRPPE in 2020 and 2021. Measurements: The questionnaire was used to evaluate learning effects. Four following items were asked on a five-point scale after the course completion. 1) Knowledge. Was oRPPE effective in understanding drug therapy? 2) Patients. Was oRPPE effective in understanding the patient's feelings? 3) Motivation. Has your motivation as a medical student improved through oRPPE? 4) Behavioral changes. Will oRPPE bring you a change in learning attitude? Analysis: Each item was compared between players and audiences. Differences were considered significant at P < 0.01.

    Results: Total participants were 194 students (Players: 110, Audiences: 84) who completed the course. We collected questionnaire from players (n=106) and audiences (n=72). Knowledge, Motivation and Behavioral changes were significantly higher in players [Mean score (95% CI). Players vs. Audiences. Knowledge 4.509 (4.317-4.702) vs. 4.139 (3.948-4.329) (p<0.001); Motivation 4.434 (4.244-4.624) vs. 3.972 (3.746-4.199) (p<0.001); Behavioral changes 4.283 (4.107-4.459) vs. 4.042 (3.847-4.237) (p=0.0098)]. On the other hand, Patients was not statistically significant between players and audiences [4.377 (4.178-4.577) vs. 4.208 (4.007-4.409) (p=0.0216)].

    Conclusions: Players showed much higher learning effects in Knowledge, Motivation and Behavioral changes. Learning as an audience, however, also established a better understanding of Patient's feeling., Japanese Pharmacological Society, Japanese
  • In vivo evaluation of novel near-infrared fluorescence probe THK565 for imaging amyloid β and tau protein deposits in Alzheimer‘s mouse models
    Naganuma Fumito, Murata Daiki, Inoue Marie, Harada Ryuichi, Kudo Yukitsuka, Nakamura Tadaho, Okamura Nobuyuki, Proceedings for Annual Meeting of The Japanese Pharmacological Society, 95, 3-O-113, 2022
    Alzheimer's disease (AD) is a progressive neurodegenerative disorder marked by the accumulation of amyloid-β (Aβ) plaques and hyperphosphorylated tau tangles. Thus, noninvasive detection of accumulated Aβ and tau in the brain would be beneficial for an early diagnosis of AD. We developed a novel near-infrared fluorescence (NIRF) probe named THK565 for in vivo imaging of Aβ and tau in the brain. In the present study, we evaluated whether THK565 can noninvasively detect Aβ and tau deposits using 2 lines of AD-model mice. We used APP-KI and rTg4510 mice which show progressive accumulation of Aβ and tau in the brain, respectively. Mice were intravenously injected with 0.3 mg/kg of THK565, and then in vivo fluorescence signals were measured using IVIS imaging system at different time point. After in vivo imaging, we harvested brain and confirmed the existence of Aβ and tau deposits by immunohistochemistry.

    In vivo NIRF imaging demonstrated higher fluorescent intensity in the brains of APP-KI and rTg4510 than in those of age-matched control mice. The histological analysis confirmed that THK565 clearly labeled Aβ and tau plaques in the brain section. These findings imply that THK565 is useful for noninvasive assessment of Aβ and tau pathology in the brain., Japanese Pharmacological Society, Japanese

  • Chemogenetic inhibition of histaminergic neurons significantly decreased wakefulness during the dark periods in mice.
    Kuroyanagi Hiroshi, Tanaka Masato, Naganuma Fumito, Nakamura Tadaho, Okamura Nobuyuki, Proceedings for Annual Meeting of The Japanese Pharmacological Society, 94, 2-Y-G1-1, 2021
    Histaminergic neurons are localized in the tuberomammillary nucleus (TMN) of the posterior hypothalamus. These neurons have been postulated to have wake-promoting and arousal-maintaining functions. Previously, we found that the acute and specific activation of histaminergic neurons in the TMN slightly increased wakefulness in mice during the light periods. However, the precise neural mechanism of histaminergic neurons in the regulation of sleep-wake cycles have remained to be elucidated. In this study, we examined the wake-regulatory mechanism of histaminergic neurons by using chemogenetic inhibition methods. We virally expressed hM4Di specifically in the TMN-histaminergic neurons of histidine decarboxylase (Hdc)-Cre mice. Then clozapine-N-oxide (CNO) or saline (SA) were injected at ZT3 (light period) or ZT12 (dark period). We found that CNO injection at ZT12 significantly decreased wakefulness and increased NREM sleep due to prolonged duration of NREM sleep. We also found that the wake to wake transition was significantly decreased and NREM to NREM sleep transition was increased in the CNO group. On the other hand, CNO injection at ZT3 did not alter sleep-wake status. These results indicated that histaminergic neurons in the TMN are important for maintaining the arousal status in mice during the dark periods., Japanese Pharmacological Society, Japanese
  • Astrocytic histamine N-methyltransferase controls locomotor activity and vigilance state
    Otsuka Rina, Naganuma Fumito, Sato Yuki, Takahashi Yuna, Yanai Kazuhiko, Yoshikawa Takeo, Proceedings for Annual Meeting of The Japanese Pharmacological Society, 94, 1-O-B3-2, 2021
    Brain histamine plays a role as a neurotransmitter in the regulation of various brain activities. Previously, we demonstrated that histamine N-methyltransferase (HNMT), a histamine-metabolizing enzyme, controls brain histamine concentration and brain functions. However, it is still unknown whether neuronal Hnmt or astrocytic Hnmt contributes to the regulation of histaminergic system. Here, we phenotyped astrocytes-specific Hnmt knockout (cKO) mice to elucidate the role of Hnmt in astrocytes. First, we made cKO mice by crossing Hnmt flox mice and Gfap-Cre mice which expressed Cre recombinase in astrocytes. Although Hnmt expression in the cKO cerebellum was decreased, brain histamine concentrations in the cKO brain homogenates was not significantly different from those of control mice. In behavioral tests, locomotor activity of cKO mice in novel environment and in their home cages were decreased during the dark phase. Anxiety- and depression-like behaviors were not changed by Hnmt deletion in astrocytes. Sleep analysis showed that the power density of delta frequency was increased in cKO mice, indicating the lower cortical activation of cKO mice. These results demonstrate that astrocytic Hnmt is important for locomotor activity and vigilance state, although the impact of Hnmt in astrocytes on histamine concentration was limited., Japanese Pharmacological Society, Japanese
  • Histamine activation of periaqueductal grey matter and somatosensory cortex exerts an antinociceptive effect in mechanical allodynia.
    Yu Mei, Yoshikawa Takeo, Naganuma Fumito, Yanai Kazuhiko, Proceedings for Annual Meeting of The Japanese Pharmacological Society, 94, 1-O-B2-1, 2021
    Histamine is a bioactive amine which is involved in diverse physiological functions including allergic reaction and gastric acid secretion. In the central nervous system (CNS), histamine acts as a neurotransmitter to control various brain functions such as sleep-wake cycle. Recent studies have shown the therapeutic action of central histamine on mechanical allodynia. However, the mechanism(s) by which histamine attenuates allodynia remain unknown. First, we investigated responsible histamine receptors for histamine-induced pain relief. Pharmacological assays showed that the activation of postsynaptic histamine H1 and H2 receptors were important for pain relief. Next, we examined which brain regions were important for pain alleviation by histamine. We decreased the function of histamine system in several brain regions by adeno-associated viruses and revealed that periaqueductal gray matter (PAG) and somatosensory cortex (SS) were involved in histamine-induced pain relief. Histaminergic activation by DREADDs (designer receptors exclusively activated by designer drugs) also confirmed the importance of PAG for pain relief by histamine. 

    These data demonstrates that histamine activation in PAG and SS has antinociceptive effects on mechanical allodynia., Japanese Pharmacological Society, Japanese

  • Histamine H1 receptor on neurons and astrocytes plays different roles in mouse behavior
    Yoshikawa Takeo, Karpati Aniko, Naganuma Fumito, Matsuzawa Takuro, Yanai Kazuhiko, Proceedings for Annual Meeting of The Japanese Pharmacological Society, 93, 2-O-033, 2020
    Histamine acts as a neurotransmitter in the brain and controls diverse brain functions. Recently, we elucidated the important roles of histamine H1 receptors (H1R) on intracellular signaling in 1321N1 cells, an astrocytoma-derived cell line. However, it was still unknown the impact of astrocytic H1R on brain functions. In the present study, we deleted mouse H1R gene from astrocytes and neurons and analyzed the phenotype of astrocyte- and neuron-specific conditional knockout mice (cKO). First, we confirmed that cell-specific reduction of H1R gene expression in cKO mice. Behavioral studies revealed that H1R on both astrocytes and neurons played an important role of anxiety-like behavior. Neuronal H1R was also involved in recognition memory. Astrocytic H1R contributed to the regulation of aggressive behavior, circadian rhythms and quality of wakefulness. In conclusion, our study stresses the importance of H1R on neurons and astrocytes in distinct physiological processes., Japanese Pharmacological Society, Japanese
  • Chronic histamine decrease in adult mice induced depression-like behavior and impaired sleep-wake cycle
    Yamada Yo, Yoshikawa Takeo, Naganuma Fumito, Yanai Kazuhiko, Proceedings for Annual Meeting of The Japanese Pharmacological Society, 93, 1-YIA-01, 2020
    Histamine acts as a neurotransmitter in the brain. Histamine is synthesized from histidine by histidine decarboxylase (HDC). In the central nervous system, HDC-positive neurons exist in tuberomammillary nucleus (TMN) of posterior hypothalamus and project their axons to entire brain. Recent studies showed that chronic histamine decrease in adult was observed in several neurological disorders such as narcolepsy and Alzheimer's disease. However, it is still unknown whether this histamine decrease plays a causative role in the disorders or not. In present study, we induced chronic histamine deficiency in adult mice to reveal the direct involvement of impaired histaminergic nervous system in brain dysfunction. We stereotaxically microinjected adeno-associated virus expressing

    Cre-recombinase into TMN of adult HDC flox mice (HDC cKO mice) for long-term brain histamine decrease. Immunohistochemical analysis showed Cre expression in TMN in HDC cKO mice. We confirmed the reduced HDC mRNA expression and the decreased histamine content in HDC cKO brain. In the tail suspension test, immobility time was prolonged in HDC cKO mice. In home-cage locomotor activity test, activity counts during light period were decreased in HDC cKO mice. Additionally, we performed sleep analysis by measuring electroencephalogram and electromyogram. The analysis showed that cKO mice exhibited decreased wakefulness during light period. These results indicated that chronic dysfunction of histamine system caused depression-like behavior and impaired sleep-wake cycle in mice., Japanese Pharmacological Society, Japanese

    Medical undergraduate students who will become medical doctors should have enough knowledge and understandings of medication since they will administer medical drugs to cure or examine the patients in hospital. Our current pharmacological practice is intended for the students to learn pharmacokinetics of drugs by focusing on administration, metabolism and excretion of aspirin. In this practice, the volunteers are recruited from students who take aspirin with or without another agent that changes the urine to acidic or basic pH. They collect the urine during 3.5 hours after taking aspirin and analyze the metabolites of aspirin in the urine. Through this practice, the students understand how aspirin is metabolized and excreted to urine and also how the urine pH affects the excretion of the metabolites in urine. The students, who will need to administer medicine to patients as physicians, are expected to acquire basic aspects of pharmacokinetics and clinical trials through this practice.

  • Role of glutamate release from melanin-concentrating hormone neurons in REM sleep regulation
    Naganuma Fumito, Nakamura Tadaho, Vetrivelan Ramalingam, Okamura Nobuyuki, Proceedings for Annual Meeting of The Japanese Pharmacological Society, 93, 0, 1, O-014, 2020

    Neurons containing melanin-concentrating hormone (MCH) localized in the posterior lateral hypothalamus and have a crucial role in rapid eye movement sleep (REMs) regulation. As MCH neurons also contain a variety of other neurotransmitters such as glutamate. However, the specific neurotransmitter responsible for REMs regulation is not known. We hypothesized that glutamate, the primary fast-acting neurotransmitter in MCH neurons, is necessary for REMs regulation. To test this hypothesis, we generated mice deleted vesicular glutamate transporter (Vglut2; necessary for synaptic release of glutamate) specifically from MCH neurons by crossing MCH-Cre mice (expressing Cre recombinase only in MCH neurons) with Vglut2flox/flox mice (expressing LoxP-modified alleles in Vglut2). We then studied the amounts, architecture and diurnal variation of sleep-wake states in baseline conditions. Next, we activated the MCH neurons lacking glutamate release using chemogenetic methods and tested whether these MCH neurons still promoted REMs. Our results indicate that glutamate in MCH neurons contributes to normal diurnal variability of REMs by regulating the levels of REMs during the dark period, but MCH neurons can promote REMs even in the absence of glutamate.

  • Deletion of brain histidine decarboxylase by adeno-associated virus induced anxiety-like behaviors in adult mice.
    Yamada Yo, Yoshikawa Takeo, Naganuma Fumito, Yanai Kazuhiko, Proceedings for Annual Meeting of The Japanese Pharmacological Society, 92, 1-P-005, 2019
    Histamine acts as a neurotransmitter in the brain. Histamine is synthesized from histidine by catalyzing histidine decarboxylase (HDC). In the central nervous system, HDC-positive neurons are in tuberomammillary nucleus of posterior hypothalamus and project their axons to entire brain. However, the roles of HDC in brain functions are not fully elucidated. In the present study, we generated mice with brain-specific deletion of HDC to investigate the importance of histamine for adult brain.

    We stereotaxically microinjected adeno-associated virus (AAV) expressing

    Cre-recombinase into tuberomammillary nucleus of adult HDC flox mice (HDC cKO mice). Immunohistochemical analysis showed Cre expression in tuberomammillary nucleus in HDC cKO mice. We confirmed the reduced HDC mRNA expression and the decreased histamine content in HDC cKO brain. Light/dark box tests showed that HDC cKO mice spent a shorter amount of time in the light room. In the tail suspension tests, immobility time was prolonged in HDC cKO mice. These results indicated that the inhibition of HDC activity in adult brain reduced histamine content and induced anxiety- and depression-like behaviors in mice., Japanese Pharmacological Society, Japanese

    Orexin and melanin-concentrating hormone (MCH) neurons innervate each other and have opposite effects for rapid eye movement sleep (REMs) regulation. Narcolepsy patients appear abnormal REMs behaviors such as rapid transitions into REMs. The causal role of orexin neurons in narcolepsy is well established, but that of MCH neurons remains unclear. We hypothesized that in the absence of orexins, the effects of MCH on REMs can be unbalanced, potentially contributing to aspects of abnormal REMs observed in narcolepsy. To test this hypothesis, we generated MCH-Cre::OX-KO mice and characterized sleep-wake behaviors and cataplexy with chemogenetic activation and pharmacological inhibition of MCH signaling.

    In mice lacking orexins, activation of the MCH neurons also increased abnormal intrusions of REMs manifest as cataplexy and short latency transitions into REMs (SLREM). Conversely, a MCH receptor 1 antagonist, SNAP 94847, almost completely eliminated SLREM and cataplexy in OX-KO mice. These findings affirm that MCH neurons promote REMs under normal circumstances, and their activity in mice lacking orexins likely triggers abnormal intrusions of REMs into non-REMs and wake, resulting in the SLREM and cataplexy characteristic of narcolepsy.

    科学研究費助成事業 基盤研究(C)
    01 Apr. 2020 - 31 Mar. 2023

    吸入麻酔薬がどのように作用し、意識を消失させるのか不明の点が多く残されている。ニューロテンシン神経系は覚醒に関連する神経核に広く投射しているので、吸入麻酔薬の意識消失作用を発揮する過程において、皮質下覚醒系を司る中心的な神経回路として重要な役割を果たしている可能性が考えられる。そこで本研究では吸入麻酔薬の意識消失作用におけるニューロテンシン神経系の役割を検証する。
    まず視床下部ニューロテンシン神経細胞の分布と投射先を同定するため、ニューロテンシン神経細胞特異的に蛍光色素を発現させ、全脳にわたり薄切し免疫染色を行った。外側視床下部にニューロテンシン神経細胞が局在し、分界条床核 BNST, 腹側外側視索前野VLPO, 前脳基底部無名質SI, 腹外側中脳水道周囲灰白質vlPAG, 腕傍核PB, 青斑核LCなどの睡眠覚醒系に関与する脳領域に、多くの神経線維を投射していることが明らかになった。また吸入麻酔におけてニューロテンシン神経細胞の活性化がどのような影響を及ぼすかを検討するために、化学遺伝学的手法でマウスの視床下部ニューロテンシン神経細胞を特異的に活性化し、吸入全身麻酔から覚醒するまでの時間を測定した。その結果、ニューロテンシン神経細胞を特異的に活性化すると、全身麻酔からの回復が早くなった。一方、麻酔投与開始から体動が消失するまでの時間は差が無かったため、ニューロテンシン神経細胞は全身麻酔の導入には影響せず、回復期の覚醒に関与することが示唆された。次に、多様な神経線維投射のどれが覚醒に関与するか詳細に検討するため、神経投射先特異的な役割を検討した。神経線維投射先特異的な神経活性を制御するために光遺伝学的手法を用いるが、ベクターの極微量注入と光ファイバー埋め込みを実施し、予備的なデータが得られた。

    The optical stimulation of neurotensinergic neurons in lateral hypothalamus (Nts-LH) during NREM sleep strongly promoted arousal in mice. In addition, in vivo calcium imaging elucidated that neuronal activity of Nts-LH was high during wakefulness compared with during sleep. These results indicated that Nts-LH is important for wake maintenance.

    Microinjection of AAV-Cre into brain regions of Hnmt (a histamine-metabolizing enzyme)-flox mice increased histamine concentration in the injected regions. Increased histamine in hypothalamus increased locomotor activity, whereas that in amygdala increased aggression behaviors, respectively. On the other hand, in Hdc (histamine synthetase)-flox mice, microinjection of AAV-Cre into hypothalamus decreased brain histamine and induced the anxiety-like behaviors and suppressed locomotor activity and aggression behaviors. These results showed that histaminergic neurons were important for locomotor activity in hypothalamus and aggression behaviors in amygdala, suggesting that histaminergic neurons have a different role in various brain regions. In addition, this study could develop the new methods to study each functions of brain histamine depend on each brain regions.

    ニューロンに発現するモノアミントランスポーターは、シナプス間隙におけるモノアミン系神経伝達物質の濃度を調節し、神経活動の恒常性を維持する上で非常に重要な役割を持っている。事実、トランスポーターを標的とした薬剤は、精神疾患などの治療に広く用いられている。近年ニューロンだけでなく支持細胞であるアストロサイトがシナプス間隙におけるモノアミン系神経伝達物質の濃度調節に関与していることが分かってきたが、そのメカニズムは未だ不明なままであった。そのため、これらのメカニズムが明らかにすることで、更なる精神疾患の病態の解明や、新規治療標的の開発に繋がると考え、実験に着手した。まず、培養細胞を用いたin vitroの実験により、アストロサイトにおけるモノアミン取り込み能およびそのメカニズムを検討した。その結果、新規モノアミントランスポーターであるplasma membrane monoamine transporter (以下PMAT) が重要な役割を果たしていることが明らかとなった。次に、生体におけるPMATの役割を明らかにするため実験を行った。まず、マウスを用い、脳部位ごとにPMATの発現量を定量PCRにより検討を行った。その結果、ほとんどの脳部位において、セロトニントランスポーターや、ノルエピネフリントランスポーターに比べ、PMATが非常に多く発現していることが明らかとなった。次に、imipramineやdecynium22といった阻害剤を投与し、マイクロダイアリシス法で細胞外モノアミン量を測定したところ、薬物投与群は対照群に加え、優位に細胞外セロトニン、ノルエピネフリン、ヒスタミン量が増加していることが明らかとなった。以上の結果から、PMATは生体においても細胞外モノアミンの除去に重要な役割を果たしていることが示唆された。これに加え、本研究ではPMAT欠損マウスの作製を行った。マウスの作製は完了したが、表現型の解析については今後の課題である。
