Eight lung fibrosis-related genes were identified: BDKRB1, CHRM3, HLA-DRB1, MMP7, PLAU, SETD2, SFTPB, and SFTPC. BDKRB1 encodes the bradykinin B1 receptor, binding to the peptide hormone bradykinin and engaging in various inflammatory response processes [92]. This evidence concerns the gene SFTPB and pulmonary fibrosis.
