The interaction between epithelial cells and macrophages plays a crucial role in the progression of lung diseases,including immune de-fense,inflammation regulation,tissue repair,and regeneration.However,an imbalance in this inter-action can contribute to the development of vari-ous lung diseases.In idiopathic pulmonary fibrosis,chronic obstructive pulmonary disease,and lung cancer,macrophages can promote disease progres-sion by secreting cytokines that act on epithelial cells.Simultaneously,activated epithelial cells re-lease cytokines to recruit and activate more macro-phages in a positive feedback loop.Thus,compre-hensive studies of the interactions between epithe-lial cells and macrophages in various lung diseases have the potential to identify new therapeutic tar-gets and develop innovative strategies for disease management.This review aims to summarize the current knowledge regarding the interaction be-tween epithelial cells and macrophages in idiopath-ic pulmonary fibrosis,chronic obstructive pulmo-nary disease,and lung cancer,with the goal of in-spiring new research directions for the treatment of lung diseases.
