What is the Origin of Gut Microbiome Markers?

This concept emerged from the rapid advancements in metagenomics and the clinical realization of the profound, bidirectional communication between the enteric microbiota and the host's systemic physiology. The term 'markers' is borrowed from clinical diagnostics, signifying measurable parameters used for assessment and risk stratification. The field of 'microbiome endocrinology' is a rapidly expanding area of research.

What is the Mechanism of Gut Microbiome Markers?

These markers operate as intermediaries in the gut-endocrine axis, influencing host metabolism and hormonal signaling. For instance, microbial production of short-chain fatty acids like butyrate acts on host G-protein coupled receptors, affecting energy balance and satiety hormones. Dysbiosis, indicated by shifts in taxonomic markers, can impair the enterohepatic circulation of estrogens, altering circulating hormone levels and contributing to systemic inflammation and metabolic dysfunction.

Gut Microbiome Markers

Meaning

Gut microbiome markers are specific biochemical, genetic, or taxonomic signatures derived from the collective microbial community residing in the gastrointestinal tract that correlate with particular physiological states, disease risk, or therapeutic responsiveness. These markers include ratios of dominant bacterial phyla, short-chain fatty acid concentrations, and specific enzyme activities that reflect microbial function. They provide critical insight into the complex gut-endocrine axis.
