Abstract
Ischemic stroke (IS) is a severe central nervous system disorder characterized by high incidence, disability, mortality, and recurrence rates, along with numerous complications. The microbiota-gut-brain axis (MGBA) represents a bidirectional communication pathway between the brain and the gut, which can influence the onset and progression of IS through neural, immunoregulatory, and gut metabolite pathways. Recent preclinical and clinical evidence supports the use of fecal microbiota transplantation (FMT), probiotics and prebiotics, dietary interventions, and antibiotics as strategies to suppress neuroinflammation in IS, protect the blood-brain barrier, modulate immune responses, and improve stroke outcomes. In this review, we summarize the manifestations of innate inflammation and adaptive immunity following the onset of IS, highlight the interactions between the MGBA and post-stroke neuroinflammation, and discuss current therapeutic measures, thus providing insights for the development of novel treatment strategies in the future.
