Research progress on the effects of gut microbiome on lung damage induced by particulate matter exposure

Air pollution is one of the top five causes of death in the world and has become a research hotspot. In the past, the health effects of particulate matter (PM), the main component of air pollutants, were mainly focused on the respiratory and cardiovascular systems. However, in recent years, the intestinal damage caused by PM and its relationship with gut microbiome (GM) homeostasis, thereby affecting the composition and function of GM and bringing disease burden to the host lung through different mechanisms, have attracted more and more attention. Therefore, this paper reviews the latest research progress in the effect of PM on GM-induced lung damage and its possible interaction pathways and explores the potential immune inflammatory mechanism with the gut-lung axis as the hub in order to understand the current research situation and existing problems, and to provide new ideas for further research on the relationship between PM pollution, GM, and lung damage.

Air pollution is a leading cause of death worldwide and has attracted significant research attention. While previous studies mainly focused on the respiratory and cardiovascular effects of particulate matter (PM), recent research has revealed the intestinal damage caused by PM and its impact on gut microbiome (GM) homeostasis. This paper reviews the latest progress in understanding the interaction between PM-induced lung damage and GM, exploring the potential immune inflammatory mechanisms through the gut-lung axis, and providing new insights for further research on the relationship between PM pollution, GM, and lung damage.
