Gastrointestinal tract microbiota modulation

Gastrointestinal tract microbiota modulation refers to the intentional alteration—through dietary changes, supplementation with specific microorganisms like probiotics/prebiotics, fecal transplants, phage therapy, or other targeted interventions—of the complex community structure and function formed by trillions of microorganisms inhabiting the human digestive tract. This ecosystem includes bacteria, archaea, fungi, and viruses that collectively influence digestion/metabolism; shape local and systemic immunity; maintain intestinal barrier integrity; produce key bioactive compounds such as short-chain fatty acids; modulate inflammation; affect neurological processes via the gut-brain axis; and directly interact with drugs through metabolic transformation. Imbalances in this ecosystem (“dysbiosis”) are linked to a wide range of diseases from gastrointestinal disorders like IBD/IBS/CDI to metabolic syndromes and neurodegeneration. Therapeutic strategies aim either at restoring balance after disruption or at shifting the community toward a configuration associated with health benefits. However—as “modulation” is an intervention strategy rather than a discrete molecular entity—it is not considered a canonical therapeutic target like an enzyme/receptor/transporter but rather describes approaches targeting an entire ecological system within the body.[1][2][3][4][6] **Note:** The entry "Gastrointestinal tract microbiota modulation" does not refer to a single molecule/receptor/protein but instead describes an intervention strategy targeting a complex biological system. Therefore it should be marked as **not a canonical target** (`is_target: false`) and **incorrect** for standard molecular target listings (`is_incorrect: true`).
