Conditional deletion of the Tgfbr2 gene in WT1+ mesothelial cells, treatment with the TGF-β1-blocking peptide p144 or p17, or use of mutant mice deficient in Smad3 all significantly attenuate the fibrotic response in (both) visceral and parietal mesothelium in several peritoneal fibrosis models153,155,159,160. Here, TGFB1 is linked to Peritoneal Fibrosis.
