Outline of Final Research Achievements

The ventromedial hypothalamus (VMH) plays an important role in feeding behavior and sympathetic nerve activity. The VMH expresses various receptors of the peptides related to feeding. In the present study, we examined the effects of feeding-related peptides on the burst-generating property of the VMH. Superfusion with insulin, pituitary adenylate cyclase-activating polypeptide, corticotropin-releasing factor and orexin increased the frequency of the VMH oscillation. In contrast, superfusion with leptin, cholecystokinin, cocaine- and amphetamine-regulated transcript, galanin, ghrelin and neuropeptide Y decreased the frequency of the oscillation. Our findings indicated that the frequency changes of VMH oscillation in response to the application of feeding-related peptides showed a tendency similar to changes of sympathetic nerve activity in response to the application of these substances to the brain.

Academic Significance and Societal Importance of the Research Achievements

低血糖から回復遅延や褐色脂肪細胞からの熱産生は、視床下部の腹内側核(VMH)を介した交感神経が調節していると考えられている。私どもが新たに発見したVMHのバーストリズムは、グルコース濃度や摂食ペプチドによってバースト頻度が変化することが確認された。さらにそのバースト頻度は交感神経活動に影響していることが証明された。したがって、このバーストリズムへの人為的な介入が、低血糖や肥満の改善の研究につながると期待できる。
