摘要
Activin A which was first described in 1986 has been shown to maintain hippocampal neuronal survival Activin A increases intracellular free Ca2+ via L type Ca2+ channels Our previous study showed that activin A promotes neurite growth of dorsal root ganglia in embryonic chickens and inhibits nitric oxide secretion The present study demonstrated for the first time that activin A could maintain cerebral cortex neuronal survival in vitro for a long period and that activin A was shown to increase voltage gated Na+ current (I-Na) in Neuro 2a cells which was recorded by patch clamp technique The present study revealed a novel mechanism for activin A as well as the influence of activin A on neurons by regulating expressions of vasoactive intestine peptide and inducible nitric oxide synthase
