Recently, signalling pathways involved in the pathogenesis of peritoneal fibrosis in PD have been studied, these include TGF‐β1‐induced signalling pathways and Toll‐like receptor ligands‐induced signalling pathways.24, 25, 26, 27 As the main factor controlling fibrosis in all organs, TGF‐β1 has been demonstrated to play a central role in MMT. The gene discussed is TGFB1; the disease is Peritoneal Fibrosis.
