摘要:
Glial cell line-derived neurotrophic factor (GDNF) plays a critical role in orchestrating the development and maintenance of different populations of central and peripheral neurons. GDNF was initially discovered by its abil-ity to promote the survival of ventral midbrain dopaminergic neurons [1]. In addition, GDNF promotes the survival and control the differentiation of motor neurons and many peripheral neurons, including sensory and sympathetic neu- rons. Moreover, it is required to induce proliferation, migration and survival of enteric neurons. GDNF promotes these trophic effects through the activation of the receptor tyrosine kinase (RTK) Ret.
