With limited treatment options and a poor prognosis, new therapies are urgently needed. This study investigates a novel cell therapy targeting pathological fibroblasts, a key driver of fibrosis.\n\nSingle-cell analyses identify CTHRC1+FAP+ fibroblasts as a collagen-producing subpopulation crucial in IPF progression. Chimeric antigen receptor (CAR) technology enables precise targeting of these cells. While CAR-Treg therapy has shown promise in preclinical models, its clinical translation requires careful safety evaluation regarding infection risk, potential tumor promotion, and immune reconstitution.\n\nThis trial employs an innovative approach using engineered dendritic cells (DCs). CAR technology is applied to generate immunosuppressive CAR-DCs (iCAR-DCs) designed to target FAP, localize to fibrotic lung areas, and attenuate fibrosis without eliciting a detrimental immune response. Preliminary mouse studies demonstrated that iCAR-DC administration following lung injury significantly reduced fibrosis without apparent organ toxicity and improved survival.\n\nThis single-arm trial aims to evaluate the efficacy and safety of this immunosuppressive CAR-DC therapy in patients with end-stage IPF. Key assessments will include changes in lung function, fibrosis extent on imaging, and comprehensive monitoring of potential adverse effects, particularly infections, tumor markers, and immune parameters.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '75 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n1\\.
