Advances in research of the neuroprotective mechanisms of cerebral ischemic postconditioning

Abstract

Ischemic postconditioning refers to controlling reperfusion blood flow during reperfusion after ischemia, which can induce an endogenous neuroprotective effect and reduce ischemia-reperfusion injury. Activation of endogenous neuroprotective mechanisms plays a key role in protecting against brain ischemia-reperfusion injury. The mechanisms of cerebral ischemic postconditioning are not completely clear, and the following aspects may be involved: downregulation of oxidative stress, attenuating mitochondrial dysfunction, attenuating endoplasmic reticulum stress, accelerating the elimination of glutamate, increasing rCBF, inhibiting apoptosis, inhibiting autophagy, and regulating signal transduction.
