TRIM72 and idiopathic pulmonary fibrosis: Considering the close association of alveolar epithelial cell dysfunction with the pathogenesis of IPF [17, 18, 22, 67] and the progenitor role of ATII cells in regenerating the distal alveoli in adult lungs [24], the potential of TRIM72 for protecting against fibrosis in injured lungs is substantial due to the beneficial effect on both ATI and ATII cells.
