Exercise-Induced Endogenous Neuroprotection In Stroke
There is increasing evidence from us and other investigators that exercise produces endogenous protection in the brain after transient ischemia. Our primary goal is to establish an endogenous neuroprotective concept of exercise preconditioning in stroke by identifying the inflammatory mechanism and the cellular sites during neovascularization. We determine the relationship between exercise-induced angiogenesis and the extent of inflammation in ischemic regions, as well as determine the inflammatory reaction in neovascularization. We address causal roles of the cellular or molecular events with relation to reduction in brain inflammation in reperfusion injury. We elucidate TNF signaling pathways that mediate differential endothelial activation and downstream inflammatory events. The proposed strategy of exercised-induced endogenous neuroprotection can be extended to other therapeutic approaches, such as pharmacology. This strategy will allow the development of combined approaches to inhibit and stimulate appropriate targets simultaneously, thus reaching the highest therapeutic potential. Moreover, it may be possible to develop an innovative procedure in which simple preconditioning exercise, administered after a “wake-up call” such as a transient ischemic attack (TIA) or before surgery, can be used to limit subsequent ischemic injury.
