Abstract

We evaluated the proinflammatory cytokines, TNF-α and IL-1β, mRNA expression in the rat sciatic and tibial nerves following ischemia-reperfusion (IR) injury, using competitive RT-PCR, to explore the role of cytokines in IR injury. The expressions of both TNF-α and IL-1β mRNA were related to severity of ischemia and occurred with reperfusion rather than ischemia alone. TNF-α gene expression peaked at 24 h of reperfusion, while that of IL-1β peaked at 12 h. These data support the notion that the proinflammatory cytokines TNF-α and IL-1β are involved in the inflammatory response of IR injury to the peripheral nervous system and may be involved in the pathophysiology of ischemic fiber degeneration.
