  19. Prostaglandin E<sub>2</sub>Induces Long-Lasting Inhibition of Noradrenergic Neurons in the Locus Coeruleus and Moderates the Behavioral Response to Stressors

    Neuronal activity is modulated not only by inputs from other neurons but also by various factors, such as bioactive substances. Noradrenergic (NA) neurons in the locus coeruleus (LC-NA neurons) are involved in diverse physiological functions, including sleep/wakefulness and stress responses. Previous studies have identified various substances and receptors that modulate LC-NA neuronal activity through techniques including electrophysiology, calcium imaging, and single-cell RNA sequencing. However, many substances with unknown physiological significance have been overlooked. Here, we established an efficient screening method for identifying substances that modulate LC-NA neuronal activity through intracellular calcium ([Ca<sup>2+</sup>]<sub>i</sub>) imaging using brain slices. Using both sexes of mice, we screened 53 bioactive substances, and identified five novel substances: gastrin-releasing peptide, neuromedin U, and angiotensin II, which increase [Ca<sup>2+</sup>]<sub>i</sub>, and pancreatic polypeptide and prostaglandin D<sub>2</sub>, which decrease [Ca<sup>2+</sup>]<sub>i</sub>. Among them, neuromedin U induced the greatest response in female mice. In terms of the duration of [Ca<sup>2+</sup>]<sub>i</sub>change, we focused on prostaglandin E<sub>2</sub>(PGE<sub>2</sub>), since it induces a long-lasting decrease in [Ca<sup>2+</sup>]<sub>i</sub>via the EP<sub>3</sub>receptor. Conditional knock-out of the receptor in LC-NA neurons resulted in increased depression-like behavior, prolonged wakefulness in the dark period, and increased [Ca<sup>2+</sup>]<sub>i</sub>after stress exposure. Our results demonstrate the effectiveness of our screening method for identifying substances that modulate a specific neuronal population in an unbiased manner and suggest that stress-induced prostaglandin E<sub>2</sub>can suppress LC-NA neuronal activity to moderate the behavioral response to stressors. Our screening method will contribute to uncovering previously unknown physiological functions of uncharacterized bioactive substances in specific neuronal populations.

    SIGNIFICANCE STATEMENTBioactive substances modulate the activity of specific neuronal populations. However, since only a limited number of substances with predicted effects have been investigated, many substances that may modulate neuronal activity have gone unrecognized. Here, we established an unbiased method for identifying modulatory substances by measuring the intracellular calcium signal, which reflects neuronal activity. We examined noradrenergic (NA) neurons in the locus coeruleus (LC-NA neurons), which are involved in diverse physiological functions. We identified five novel substances that modulate LC-NA neuronal activity. We also found that stress-induced prostaglandin E<sub>2</sub>(PGE<sub>2</sub>) may suppress LC-NA neuronal activity and influence behavioral outcomes. Our screening method will help uncover previously overlooked functions of bioactive substances and provide insight into unrecognized roles of specific neuronal populations.

  20. Deficiency of orexin signaling during sleep is involved in abnormal REM sleep architecture in narcolepsy

    Narcolepsy is a sleep disorder caused by deficiency of orexin signaling. However, the neural mechanisms by which deficient orexin signaling causes the abnormal rapid eye movement (REM) sleep characteristics of narcolepsy, such as cataplexy and frequent transitions to REM states, are not fully understood. Here, we determined the activity dynamics of orexin neurons during sleep that suppress the abnormal REM sleep architecture of narcolepsy. Orexin neurons were highly active during wakefulness, showed intermittent synchronous activity during non-REM (NREM) sleep, were quiescent prior to the transition from NREM to REM sleep, and a small subpopulation of these cells was active during REM sleep. Orexin neurons that lacked orexin peptides were less active during REM sleep and were mostly silent during cataplexy. Optogenetic inhibition of orexin neurons established that the activity dynamics of these cells during NREM sleep regulate NREM–REM sleep transitions. Inhibition of orexin neurons during REM sleep increased subsequent REM sleep in “orexin intact” mice and subsequent cataplexy in mice lacking orexin peptides, indicating that the activity of a subpopulation of orexin neurons during the preceding REM sleep suppresses subsequent REM sleep and cataplexy. Thus, these results identify how deficient orexin signaling during sleep results in the abnormal REM sleep architecture characteristic of narcolepsy.

    睡眠は概日時計による調節が存在する事が古くから示唆されているものの、その神経メカニズムの理解はほとんど進んでこなかった。このような混沌とした状況の中、申請者らは世界で初めて、睡眠・覚醒調節を担う概日時計中枢である視交叉上核からの出力神経回路を明らかにしてきた (Ono et al., 2020 Science Advances)。その後研究はさらに発展し、複数の神経経路が睡眠覚醒に関わる可能性を得ている。本研究提案では、新規発光・蛍光イメージングツールと光操作、神経トレーシング技術、in vivoゲノム編集を組み合わせ、睡眠・覚醒の概日時計制御に関わる新たな神経回路の同定を目指す。

    冬季の厳しい環境を乗り越える動物の生体機能として、冬眠や休眠が知られている。これまで、冬眠や休眠が「概日時計」により調節されている事が、現象として理解されてきたが、その分子・神経メカニズムは手つかずのままであった。しかし我々は、哺乳類の概日時計中枢からの出力経路の探索により、休眠を調節する概日時計中枢からの出力経路の新たな手掛かりを得た。また、概日時計による冬眠調節メカニズム解明に向け、遺伝子改変ハムスターの作成にも成功し、冬眠・休眠調節メカニズムを神経回路レベルで明らかにできる準備が整った。本研究では、時間生物学的視点から、冬眠や休眠を調節する新規分子・神経メカニズムの全貌に迫る。

    ゲノム解析技術の著しい進歩により、突然変異が原因となり次世代に引き継がれる遺伝性疾患が数多く同定され、10,000種以上存在すると推測されている。出生前診断等遺伝子診断の発展により、ダウン症を始めとする様々な難治性遺伝病の診断が胎児又は新生児期に判明する時代になりつつあるが、現状で有効な治療法は少なく、対症療法のみである。本研究課題では、マウス胎児期での脳ゲノム編集機構を明らかにすることで、神経疾患治療における臨界期で高効率な遺伝子修復を行える画期的な遺伝病治療法の確立を目指す。

    哺乳類における概日時計の中枢は、視床下部に位置する「視交叉上核」に存在し、時計遺伝子群の転写・翻訳を介したフィードバックループにより24時間のリズムが生成される。そのリズムは外界の明暗環境に同調し、最終的に睡眠・覚醒や体温リズムなど様々な生理機能の時間的調節を行う。これまで研究から、現象的に概日時計がこれらの生理機能を調節している事が示されてきたが、実際どの神経回路がどの生理機能の時間調節に関与するのかは不明であった。本研究では、光遺伝学、光イメージング、神経トレーシング、ゲノム編集など様々な最新の技術を組み合わせ、概日時計による体温調節メカニズムを神経回路レベルで明らかにする。

    現代の時間生物学の基盤を創ったユルゲン・アショフは、ヒトの体内には自律的に約24時間周期で振動する時計、「概日時計」の存在を発見し、体温と睡眠・覚醒の概日リズムが乖離する事を報告した。彼は、ヒトの時間感覚は体温リズムではなく、睡眠・覚醒のリズムに影響を受ける事を提示した。これらの事は、ヒトの“時間”は体温調節系と睡眠・覚醒調節系の二種類存在する事を示す。しかし、これら二つの時間調節に関わる神経経路はほとんど明らかにされていない。本研究では中枢概日時計を起点とする、睡眠・覚醒リズムと体温リズム調節に関わる神経経路を明らかにし、ヒトが持つ異なる二つの時間の存在意義に迫る。

    生体の時間調節機構に重要な役割を持つのが概日時計である。この概日時計は、睡眠・覚醒といった生体の24時間のリズムを作り出すぺースメーカーとして機能し、その中枢概日時計が、脳内の視床下部に位置する視交叉上核に存在する。この視交叉上核を電気的に破壊すると、24時間の体内のリズムが破綻し、様々な生理機能の時間的秩序が崩壊する事から、生理機能のタイミングに視交叉上核が重要な役割を持つことが示唆されている。本研究では、マウスの生理機能のタイミングを調節する神経メカニズムを明らかにし、概日時計が制御するシンギュラリティ神経回路の同定を目指す。

    When considering the output from the suprachiasmatic nucleus to sleep-wake behavior, it is known that neural activity in the suprachiasmatic nucleus is enhanced during the daytime, even though the time zones of behavior are reversed between day and night in diurnal and nocturnal animals. This study aims to clarify the neural mechanisms responsible for diurnal and nocturnal behavior by combining various imaging techniques. So far, we have verified that it is possible to measure specific neural activities through the development of bioluminescence imaging tools. However, the mechanisms that determine diurnal and nocturnal behavior have not yet been elucidated.

    概日時計中枢である視交叉上核からの出力経路を同定するため、昨年度までは順行性のトレーシング、光遺伝学を用いた細胞操作により、室傍核CRF神経の活性化により覚醒が誘導されることを明らかにした。本年度は、室傍核CRF神経特異的に、蛍光カルシウムプローブである、GCaMP6を発現させ、光ファイバーを挿入し、REM, NREM睡眠、覚醒の各ステージにおけるカルシウム変動を計測した。室傍核CRF神経の活動は、覚醒時に上昇し、REM, NREM睡眠時には低下する事が明らかとなった。さらに、CRF神経の活動は、覚醒の初期に上昇するが、その後の覚醒の間に徐々に活動が低下していった。この結果は、室傍核CRF神経は、覚醒を誘導するが、その維持には必要ではないことが明らかになった。
    次にDREADDを用いて、室傍核CRF神経特異的に神経活動を抑制する試みを行った、CNOをマウスの活動が高くなる暗期直前に投与し、神経活動の抑制を行った。コントロールは生理食塩水の投与とした。その結果、CNOの投与により、暗期の覚醒量が減少し、NREM睡眠が上昇した。さらに、ジフテリアトキシンA断片を用い、室傍核CRF神経特異的な神経脱落を行い、自発行動量の計測を行った。その結果、室傍核CRF神経の選択的な脱落により、マウスの自発行動量の低下が認められた。これらの結果は、室傍核CRF神経が覚醒に関わることをサポートする結果である。
    室傍核CRF神経の活性化、抑制化実験、ファイバーフォトメトリー実験などメインとなる実験データが得られている事、現在論文を投稿中であり、当初の計画以上の進展があるといえる。
    室傍核CRF神経の上流および下流の神経細胞群の同定を進めると同時に、この経路以外で、視交叉上核の概日リズム情報が出力されている領域を同定する。順行性・逆行性のトレーシング、光遺伝学、光計測などの技術を組みあわせ研究を進める。

    We aimed to clarify the self-organizing mechanisms for the hierarchical multi-oscillator structure of the mammalian circadian clock in the suprachiasmatic nucleus (SCN) using knockout mice for clock genes and neuropeptides functions, luciferase reporter mice for continuous monitoring clock gene expression, and fluorescence sensors for monitoring intracellular calcium and membrane potentials. We demonstrated that both VIP and vasopressin act as synchronizers for cellular rhythms. We also found that their roles change depending on postnatal development, in which clock gene Cry is involved. We also found that GABA in the SCN acts not in cellular rhythm generation but in coherent neural rhythm output from the SCN to make the central circadian clock free of bursts. We further found that Per1 rhythms in the discrete areas in the SCN are involved in transferring photoperiodic signals to behavior rhythm output by changing the phase relations.

    In freely moving mice, clock gene expression, continuously recorded by luciferase reporter from the suprachiasmatic nucleus (SCN), exhibits ultradian rhythms in addition to the circadian gene expression rhythm. Since the ultradian periodicities were similar in three clock genes, we hypothesized the common mechanisms generating ultradian rhythms within or near the SCN. In the present study, we aimed to find out the common mechanisms underlying these rhythms.
    We found that the ultradian oscillation originated not in the SCN but in the paraventricular nucleus and subparaventricular zone using the co-culture system and calcium imaging. Glutamate and GABA are involved in generating ultradian rhythms. Using an optical fiber system for measuring bioluminescence continuously, we measured Per1-luc and Bmal1-ELuc expression rhythms and found that two rhythms were transiently uncoupled after phase-delaying light pulse. We further confirmed the two rhythms can be separable in culture system.
