The gastrointestinal microbiome as a biological process encompasses the dynamic interactions, succession, and functional activities of microbial communities residing along the digestive tract and their continuous crosstalk with the host. It involves microbial colonization, competition, and cooperation; fermentation of dietary substrates; synthesis and biotransformation of metabolites such as short-chain fatty acids and bile acid derivatives; modulation of epithelial barrier integrity; and regulation of local and systemic immune responses. This process is characterized by context-dependent compositional shifts (e.g., in response to diet, xenobiotics, and inflammation) that influence host metabolism, signaling pathways, and susceptibility to gastrointestinal and extraintestinal diseases.
A research collaboration has developed a novel fluorescent nanosensor capable of rapidly detecting indole-3-propionic acid (IPA), an emerging biomarker linked to gut health and disease. The breakthrough is described in the ...
