Matrix metalloproteinase 10 and the slow demise of the peritoneal membrane

Matrix metalloproteinases (MMPs) cleave matrix components along with multiple other effects. They are integral to virtually all biological processes, including inflammation and wound healing. As such, MMPs have been studied in the context of peritoneal membrane injury. MMP10 is a stromelysin and is involved in the degradation of matrix proteoglycans. Ishimura et al. demonstrate that MMP10 is involved in peritoneal membrane fibrosis. The clinical implications of these observations are presently unknown.
