In this review, we summarize recently developed CAR T cell therapeutic strategies for IPF treatment with optimal targeting of FAP-fibroblasts, synthesize the existing preclinical studies and clinical trials evaluating anti-FAP CAR T cells to date, and critically discuss the adverse events associated with CAR T therapy alongside strategies to overcome current limitations of CAR T cell therapy in IPF management. This evidence concerns the gene FAP and idiopathic pulmonary fibrosis.
