| 内容記述 | Nesfatin-1, processed from nucleobindin 2, is an anorexigenic peptide expressed in the brain and several peripheral tissues including the stomach and pancreas. Peripheral, as well as intracerebroventricular, administration of nesfatin-1 suppresses feeding behavior, though underlying mechanisms are unknown. In this study, we examined effects of nesfatin-1 on cytosolic Ca2+ concentration ([Ca2+]i) in the neurons isolated from the vagal afferent nodose ganglion of mice. Nesfatin-1 at 10-10-10-8 M increased [Ca2+]i in the isolated neurons in a concentration-dependent manner, and at 10-8 M it increased [Ca2+]i in 33 out of 263 (12.5%) neurons. These responses were inhibited under Ca2+-free conditions and by N-type Ca2+ channel blocker, ω-conotoxin GVIA. All the nesfatin-1-responsive neurons also exhibited [Ca2+]i responses to capsaicin and cholecystokinin-8. These results provide direct evidence that nesfatin-1 activates vagal afferent neurons by stimulating Ca2+ influx through N-type channels, demonstrating the machinery through which peripheral nesfatin-1 can convey signals to the brain. © 2009 Elsevier Inc.
