Abstract
Commensal microbes are involved in intestinal homeostasis, and the dysregulation of host-microbe
interactions may lead to the development of local and systemic disorders. Recent evidence
indicated that microbiota dysbiosis plays a key role in the pathogenesis of inflammatory bowel
disease and metabolism-related disorders. The circadian clock system originally identified in the
brain was later found in the gastrointestinal tract. Although the light-controlled central clock in
the brain is responsible for the synchronization of peripheral clocks, the timing of meal consumption
serves as another cue for the rhythmic setting of gastrointestinal digestion, absorption, and epithelial
renewal and barrier functions. Multiple lines of evidence have indicated that in addition to daylight
and food intake, microbiota (as an environmental factor) are involved in the circadian control of
gut homeostasis. Recent studies demonstrated that microbial metabolites and innate signaling
orchestrate the host circadian rhythm, revealing unforeseen molecular mechanisms underlying the
regulatory role of microbiota in intestinal physiology and systemic metabolism. In this review, we
discuss the host-microbe interplay that contributes to the regulation ...
