Gut Microbiome Signaling

Meaning

This describes the complex bidirectional communication network, known as the gut-brain-endocrine axis, between the commensal microorganisms residing in the gastrointestinal tract and the host’s hormonal and nervous systems. The gut microbiome produces numerous bioactive molecules, including short-chain fatty acids and neurotransmitter precursors, that act as signals to influence host physiology. This signaling is essential for regulating metabolism, immune function, and neuroendocrine balance.
