The gut–brain axis: mechanisms linking intestinal dysbiosis with stroke (opens in new tab)

Gut microbiota has emerged as a key regulator of immune, metabolic, and neuroinflammatory processes, exerting significant influence on central nervous system (CNS) function via the gut-brain axis. Growing evidence suggests that gut dysbiosis not only precedes and worsens stroke severity but is also induced by stroke itself, establishing a bidirectional and self-reinforcing pathological loop. Microbiota-derived metabolites, including short-chain fatty acids and tryptophan derivatives, modulate...
