摘要

Neurotrophins, secreted in an activity- dependent manner, are thought to be involved in the activity- dependent refinement of synaptic connections. Here we dem- onstrate that in hippocampal neurons and the rat pheochro- mocytoma cell line PC12 application of exogenous neurotrophins induces secretion of neurotrophins, an effect that is mediated by the activation of tyrosine kinase neuro- trophin receptors (Trks). Like activity-dependent secretion of neurotrophins, neurotrophin-induced neurotrophin secretion requires mobilization of calcium from intracellular stores. Because neurotrophins are likely to be released from both dendrites and axons, neurotrophin-induced neurotrophin re- lease represents a potential positive feedback mechanism, contributing to the reinforcement and stabilization of synaptic connections.
