摘要: Fas (also known as CD95), a member of the tumour-necrosis receptor factor family 'death receptors', can induce apoptosis or, conversely, deliver growth stimulatory signals. Here we report that crosslinking on primary sensory neurons induces neurite through sustained activation extracellular-signal regulated kinase (ERK) pathway and consequent upregulation p35, mediator outgrowth. In addition, functional recovery after sciatic nerve injury is delayed in Fas-deficient lpr mice accelerated by local administration antibodies against Fas, which indicates engagement may contribute to regeneration vivo. Our findings define role for an inducer both vitro
