Lipoic acid (LA) is a naturally occurring compound and dietary supplement with powerful antioxidant properties. Although LA is neuroprotective in models of stroke, little is known about the cellular mechanisms by which it confers protection during the early stages of ischemia. Here, using a rat model of permanent middle cerebral artery occlusion (MCAO), we demonstrated that administration of LA 30min...
Ischemic tolerance describes a phenomenon whereby subcritical stimuli evoke cellular protective mechanisms resulting in increased tolerance to subsequent ischemia. In the present study we propose that the cytoprotective effects attributed to 17β-estradiol and tunicamycin in an in vivo rodent model of ischemia are reflected by changes in neuronal tissue levels of m-calpain, HSP70, GRP94 and GRP78....
