Gastrointestinal microbiota composition modulation (None established; sometimes referred to as "gut microbiota modulation" in the literature[1].)

"Gastrointestinal microbiota composition modulation" refers broadly to any intentional alteration—through diet, supplementation with live microorganisms (“probiotics”), prebiotic compounds that feed beneficial bacteria (“prebiotics”), antibiotics that suppress certain populations, or even fecal transplants—of the complex ecosystem comprising trillions of microorganisms within the human digestive tract. The goal is typically restoration or maintenance of eubiosis—a balanced state associated with health—or correction/prevention/treatment of disease states linked with dysbiosis. This field recognizes that shifts in microbial populations can profoundly affect host physiology including metabolism, immune function, inflammation control and even neurological outcomes via metabolite production and signaling pathways between microbes and host tissues. Because it describes an approach encompassing numerous targets/mechanisms/species/metabolites—and not one discrete druggable entity—it should be classified under “Other” rather than traditional molecular targets like receptors or enzymes.[1][2][3][4]

Not applicable for this entry as it is not one mechanism but encompasses multiple strategies: Introduction/supplementation with beneficial microbes ("probiotic effect"); Promotion of beneficial microbe growth via substrates ("prebiotic effect"); Suppression/elimination of pathogenic/harmful microbes via antibiotics or bacteriophages; Restoration/replacement through fecal transplant. These mechanisms ultimately aim to shift the overall community structure toward health-associated profiles.
