Microbiota modulation

Microbiota modulation describes a therapeutic strategy for altering the structure and function of the host’s microbiota—the diverse communities of microorganisms residing in human tissues, especially the gut—to prevent or treat disease. Approaches include dietary interventions, supplementation with probiotics/prebiotics, antibiotic therapy, fecal microbiota transplantation, and more recently microbial consortia and engineered microbes. The aim is to restore microbial balance, enhance beneficial bacterial populations, modulate immune responses, and prevent colonization by pathogens. This modality is being investigated for a wide array of disorders, including gastrointestinal, metabolic, autoimmune, infectious, and neurodegenerative diseases. Notwithstanding its promise, microbiota modulation presents unique safety and regulatory challenges—especially regarding standardization, adverse reaction risk, and personalized response. It is a broad process rather than a molecular target, and as such, it does not fit the conventions of target annotation for databases in pharmacology or drug discovery.
