Abstract

Tumor necrosis factor-alpha (TNF-alpha) derived from activated Schwann cells (SCs) plays a critical role as an inflammatory mediator in the peripheral nervous system disease. TNF-alpha could act as an autocrine mediator in SC activation. In this study, we found knockdown Src-suppressed protein kinase C substrate (SSeCKS) expression suppressed TNF-alpha production induced by TNF-alpha, overexpression of SSeCKS could promoted TNF-alpha autocrine in SCs. Such effects might be resulted in SSeCKS promoted p38 and JNK activation in SCs treated by TNF-alpha. Thus present data show that while SCs activation, SSeCKS may plays an important role in the release of inflammatory mediators.
