Dissecting proteolytic pathways in the skin
Proteases play pivotal roles in normal skin homeostasis and its responses to inflammation and injury. Importantly, aberrant protease activity has been identified as a contributor to inflammatory skin diseases and the pathogenesis of chronic wounds. To further unravel the mechanisms of protease action in skin inflammation and repair, we have applied iTRAQ-TAILS, a novel multiplex quantitative proteomics platform for the analysis of N-terminomes, to dissect proteolytic pathways in normal and inflamed mouse skin as well as in a porcine wound healing model. This analysis revealed known proteolytic pathways, such as blood coagulation and complement activation, but also unexpected substrate cleavages and interactions of proteolytic systems.
