title: Neurotrophins, neurones and peripheral nerve regeneration.
abstract: Successful peripheral nerve regeneration requires optimal conditions both in the macro-environment and micro-environment. Many methods have been used to improve the macro-environment for the regenerating nerve. However, much less is known about the micro-environment, and in particular the complex neurochemical interactions involved. Several neurotrophic factors have been shown to play an essential trophic role in the development, maintenance and regulation of neuronal function. These include nerve growth factor (NGF) and several recently identified members of the NGF family, namely brain-derived neurotrophic factor (BDNF), neurotrophin-3 (NT-3), neurotrophin-4/5 (NT-4/5) and neurotrophin-6 (NT-6). In this review we summarize recent studies of the effects of these neurotrophins on neurones, especially their effects on motor neurones and their axonal outgrowth. We discuss prospects for the future and point out what remains to be understood about the role of neurotrophins to enhance peripheral nerve regeneration.
