Microbiome-Driven Therapeutics: From Gut Health to Precision Medicine

The human microbiome, a complex ecosystem of microorganisms residing in and on the body, plays a pivotal role in the regulation of a wide range of physiological processes, including digestion, immune responses, and metabolic functions. In recent years, the rapidly growing field of microbiome-driven therapeutics has garnered significant attention owing to its potential to revolutionize healthcare. This review explores the evolving landscape of microbiome-based therapies, with a particular focus on the gut microbiome and its implications for both gut health and precision medicine. We highlight recent advances in understanding how microbial communities influence disease pathogenesis and treatment outcomes, spanning conditions such as inflammatory bowel disease (IBD), metabolic disorders, neurological diseases, and even cancer. This article also discusses emerging therapeutic strategies, including probiotics, prebiotics, fecal microbiota transplantation (FMT), and microbial-based drugs, as well as the challenges associated with their clinical implementation. Additionally, we examined how the integration of microbiome profiling and metagenomic data is advancing the field of precision medicine, paving the way for personalized and effective treatments. This review serves as a comprehensive resource that synthesizes current knowledge, identifies key gaps in microbiome research, and offers insights into the future direction of microbiome-driven therapeutics, thus providing a valuable framework for clinicians, researchers, and policymakers seeking to harness the potential of microbiomes to advance personalized healthcare solutions.
