Abstract

Emerging research underscores the pivotal role of the gut-immune-brain axis, a dynamic bidirectional communication system involving intricate interactions between the gut microbiota, immune responses, and the central nervous system. Gut microbes and their metabolites have profound effects on immune and neurological homeostasis, influencing the development and function of multiple physiological systems. Disruption of the composition of the gut microbiota and barrier integrity has been implicated in various neurological and psychiatric disorders, including autism spectrum disorder, Alzheimer's disease, Parkinson's disease, depression, and anxiety. Most insights into these host-microbiota interactions come from…
