Outline of Final Research Achievements

In the present study, we aimed to elucidate the mechanism of respiratory rhythm generation, focusing on the role of astrocytes in respiratory rhythm generation and hypoxic respiratory responsiveness. For this purpose, we used the isolated brainstem spinal cord preparation made of neonatal rats. We analyzed the neuronal and astrocytic activities in the medullary respiratory center by calcium imaging simultaneously recording neural respiratory output. We found that subsets of neurons and astrocytes showed oscillatory activities that were synchronized with inspiratory activities. The identified respiratory-synchronized activities of these astrocytes were not dependent on neuronal activities but spontaneous. Further, we found that TRPA1 channels expressed on the medullary astrocytes sense hypoxia and mediate augmenting hypoxic respiratory responsiveness.

Academic Significance and Societal Importance of the Research Achievements

安静時のみでなく、運動時や睡眠中も、脳での呼吸調節により体内の酸素化状態を常に適正に保つことが重要であるが、脳はどのように呼吸リズムを形成し、酸素レベル低下時に呼吸を増強させるかは、解明されていない。本研究により、延髄呼吸中枢のグリア細胞・アストロサイトは、呼吸リズム形成において重要な役割を果たし、さらに低酸素のみでなく二酸化炭素によって興奮することが確かめられ、低酸素血症および高二酸化炭素血症を呈するCOPD等の呼吸器疾患症例における呼吸調節において重要な役割を果たしている可能性が示唆された。この成果は様々な呼吸調節障害症例の病態理解および新規治療法開発に基礎的知見を提供すると期待される。
