Progress of research on short-chain fatty acids, metabolites of gut microbiota, and acute ischemic stroke.

Abstract

Acute ischemic stroke (AIS) significantly impacts the well-being and quality of life of individuals within our population. Short-chain fatty acids (SCFAs), metabolites produced by the intestinal microbiota, are integral to the bidirectional regulatory pathway linking the gut and the brain. SCFAs may significantly influence the risk, prognosis, recurrence, and management of complications associated with AIS. Potential mechanisms underlying these effects include the facilitation of brain-gut barrier repair, the mitigation of oxidative stress, the reduction of neuroinflammatory responses, and the inhibition of autophagy and apoptosis. Consequently, SCFAs hold promise as a prospective target for AIS intervention, with the potential to significantly impact AIS prevention and treatment strategies.
