This Review discusses the intricate and potentially important connections between the gut microbiota and the brain, involving bidirectional communication along the gut-brain axis. Emerging evidence suggests that disruptions in microbial communities may be implicated in neurological disorders, with animal models providing valuable insights into the pathways linking the gut and the brain which could have tangible impacts on human health.
In this Review, Morais, Schreiber and Mazmanian discuss emerging and exciting evidence of intricate and potentially important connections between the gut microbiota and the brain involving multiple biological systems, and possible contributions by the gut microbiota to complex behaviours. In a striking display of trans-kingdom symbiosis, gut bacteria cooperate with their animal hosts to regulate the development and function of the immune, metabolic and nervous systems through dynamic bidirectional communication along the 'gut-brain axis'. These processes may affect human health, as certain animal behaviours appear to correlate with the composition of gut bacteria, and disruptions in microbial communities have been implicated in several neurological disorders. Most insights about host-microbiota interactions come from animal models, which represent crucial tools for studying the various pathways linking the gut and the brain. However, there are complexities and manifest limitations inherent in translating complex human disease to reductionist animal models. In this Review, we discuss emerging and exciting evidence of intricate and crucial connections between the gut microbiota and the brain involving multiple biological systems, and possible contributions by the gut microbiota to neurological disorders. Continued advances from this frontier of biomedicine may lead to tangible impacts on human health.
