Abstract:

OBJECTIVES: Cerebral ischemia is a neurological condition in which energetics and oxidative stress are dysregulated. Resveratrol is a stilbene with potent pharmacological effects associated with its antioxidant properties. In the brain, resveratrol produces protective responses against ischemia, decreases infarct volume and improves neurological function. Adenosine monophosphate-activated protein kinase (AMPK) is a cellular sensor that acts as a switch to initiate adaptive changes in response to fluctuations in energy metabolism.

RESULTS: In ischemia, AMPK is activated, nevertheless conflicting results about its contribution to protection have become apparent, and this matter continues without resolution. Interestingly, AMPK activation by resveratrol has been implicated in regulating cell survival in different experimental models. Although resveratrol's ability to regulate AMPK directly or after signaling is only beginning to be understood, targeting this enzyme by resveratrol in brain suggest that it could contribute to the amelioration of some pathologic features induced after an energetic deficit.

CONCLUSION: The present review discusses the potential role of resveratrol in regulating AMPK activity on brain before, during, or after ischemia and offer suggestions for feasible future studies.
