Skin • tissue fibrosis • scleroderma • cartilage • osteoarthritis • TGF-beta
My research focuses on understanding the role of TGF-beta signaling in wound healing and scarring in the skin, and in the maintenance and repair of cartilage. In the cartilage, our studies center on understanding how the functional interplay between TGF-beta receptors and co-receptors regulates chondrocyte phenotype and function, in healthy and osteoarthritic cartilage. Our research on skin focuses on TGF-beta co-receptors as regulators of TGF-beta signaling in skin cells. We have recently shown that CD109, a novel TGF-beta co-receptor that we have identified in skin cells, inhibits TGF-beta signaling and displays potent anti-fibrotic properties in vitro and in vivo. One of our major objectives is to develop CD109-based peptides as TGF-b antagonists and anti-fibrotic agents for the treatment of pathological conditions such as hypertrophic scarring and scleroderma. Research in my laboratory is funded by the Canadian Institute for Health Research (CIHR), NSERC and United States Department of Defense.
