| Research Abstract |
Pirfenidone is a novel anti-fibrotic agent used in the treatment of idiopathic pulmonary fibrosis. Keloid is a cutaneous fibrotic disease characterized by fibroblast overproliferation and fibrogenesis such as the abnormally high production of alpha smooth muscle actin and collagen in keloid-derived fibroblasts. The effects of pirfenidone on cell proliferation, type I collagen production, and alpha-smooth muscle actin expression in keloid-derived fibroblasts were investigated in this study.
Results showed that pirfenidone significantly inhibited cell proliferation, type I collagen production, and alpha-smooth muscle actin expression in keloid-derived fibroblasts. Our study highlights the potential use of pirfenidone in the treatment of keloids.
