Core Tip
Core Tip: The gut-lung axis represents a bidirectional communication network that links the gastrointestinal and respiratory systems through microbial, immune, and metabolic pathways. This review synthesized recent advances in understanding how gut dysbiosis, microbial translocation, immune dysregulation, and epigenetic modifications contribute to gastrointestinal-pulmonary comorbidities. We highlighted key clinical phenotypes and explored emerging therapeutic strategies, including microbiota-targeted interventions, metabolite supplementation, and immune modulation. Future efforts should emphasize multi-omics integration, organoid-based models, and artificial intelligence-driven predictive analytics to advance precision medicine anchored in the gut-lung axis.
