Outline of Research at the Start

咀嚼・嚥下といった口腔顔面のパターン運動は,頭頸部の筋を支配する運動ニューロンの協調活動により制御される.このパターン運動の形成は脳幹網様体で行われるが,網様体の入出力系が複雑であることから,運動パターン形成機構から運動ニューロンにいたるまでのネットワークには不明な点が多い.申請者はこれまでに,網様体コリン作動性介在ニューロンが口腔顔面筋運動ニューロンと連絡し,運動ニューロンの協調活動に関与する可能性を明らかにした.そこで本研究では,網様体コリン作動性介在ニューロンに注目することで,既知の①運動パターン形成機構と運動ニューロンとの神経連絡,②その情報伝達の分子機構について形態学的解明を目指す.

Outline of Final Research Achievements

Orofacial motor neurons receive cholinergic inputs from premotor neurons in the brainstem reticular formation. We injected a retrograde tracer into the caudal medulla reticular formation that contains cholinergic premotor neurons and examined the distribution of tracer-labeled neurons. Retrogradely labeled neurons were distributed in the intermediate and parvicellular reticular formations and the raphe nuclei. This result provides the possibility that cholinergic premotor neurons connect to the pattern generation network in the brainstem, because the reticular formation plays a role in the pattern movement of orofacial muscles. The expression of synaptic markers was also investigated in cholinergic C-terminals on orofacial motor neurons during mouse postnatal development.

Academic Significance and Societal Importance of the Research Achievements

本研究では,脳幹網様体に分布するコリン作動性プレモーターニューロンに注目し,口腔顔面筋の運動ニューロンに出力する神経連絡の解析に取り組んだ.睡眠時無呼吸症候群といった疾患は口腔顔面筋のパターン運動制御の障害に原因の一部があると考えられており,その病態理解にプレモーターニューロンの神経連絡の形態学的情報は有用な知見となる.本研究課題により,網様体のコリン作動性プレモーターニューロンが脳幹網様体,縫線核などから入力を受ける可能性が示され,運動パターン形成にコリン作動性投射も関与することが示唆された.
