Intestinal microbiota modulation

Intestinal microbiota modulation refers to the deliberate alteration—through dietary changes, supplementation with probiotics/prebiotics, antibiotics, bacteriophage therapy, fecal microbiota transplantation, or other interventions—of the composition and/or activity of the complex microbial communities residing within the gastrointestinal tract. The goal is typically to restore balance (“eubiosis”) when dysbiosis has occurred due to disease states such as infections, inflammatory disorders, metabolic syndrome, neurodegenerative diseases like Alzheimer’s disease, and even psychological stress-related conditions. These interventions can influence a wide range of physiological processes including nutrient metabolism; maintenance and repair of the intestinal barrier; regulation/modulation of local and systemic immune responses; production/absorption/metabolism of key metabolites such as short-chain fatty acids; communication along the gut-brain axis; resistance against pathogen colonization; and overall host health outcomes. While not a single molecular target but rather an ecosystem-level intervention strategy affecting many molecular pathways simultaneously—and thus not considered a canonical therapeutic “target” like a receptor or enzyme—the concept is central to emerging therapies in gastroenterology and beyond.[1][2][3][4] **Note:** "Intestinal microbiota modulation" is not itself a molecule/receptor/therapeutic target but describes an intervention strategy aimed at altering an entire biological system. It does not fit standard definitions for drug targets such as receptors or enzymes.[1][2]
