The Significant Roles of Gut-lung Microbiota in Shaping and Regulating Immunity / 中山大学学报(医学科学版)

ABSTRACT

The interaction between microbes and the human immune system has long been a focus in biomedical research. Next-generation sequencing has revealed that in addition to gut microbiota， the respiratory tract also harbors microbial communities， forming an interconnected network with the gut microbiota through immune cells and active factors. This review aims to explore how the gut and lung microbiota regulate immune responses， including their roles in local and systemic immune modulation. It also delineates the immunological connections along the gut-lung axis. Further elucidating the influence of microbes on the immune system holds important clinical significance for understanding diseases and exploring novel diagnostic and therapeutic strategies.
