TGFB1 and fibrosis: This study evaluated the short-term efficacy of corisin neutralization in advanced transforming growth factor-β1 (TGF-β1)-driven lung fibrosis.<h4>Methods</h4>Male TGF-β1 transgenic mice with established fibrosis were allocated to computed tomography-matched groups and treated intraperitoneally with an anti-corisin monoclonal antibody (clone 21A) or control IgG every two days for one week.
