Host-Microbe Interactions: Mechanisms, Implications, and Therapeutic Perspectives

Abstract

Host-microbe interactions form the foundation of health and disease, encompassing complex relationships between humans and their commensal, symbiotic, and pathogenic microorganisms. These interactions influence immunity, metabolism, tissue development, and disease susceptibility. Advances in genomics, microbiome research, and systems biology have revealed that microbial communities modulate host physiology through immune signaling, metabolite production, and gene regulation. Dysbiosis, the perturbation of microbial balance, contributes to infections, chronic inflammation, metabolic disorders, and cancer. This mini-review summarizes current understanding of host-microbe interactions, highlighting key mechanisms of microbial colonization, immune modulation, and pathogenic invasion. It also explores the clinical implications of microbial dysbiosis and evaluates emerging therapeutic approaches, including probiotics, prebiotics, and microbiome-targeted interventions. Understanding these interactions offers promising avenues for novel diagnostics, preventive strategies, and personalized therapeutics.
