Multiplexed analysis of matrix metalloproteinases in leg ulcer tissue of patients with chronic venous insufficiency before and after compression therapy

Elevated matrix metalloproteinases (MMP) levels have been implicated in the pathogenesis of chronic venous insufficiency ulcers. Quantitative measurements of a broad range of MMP proteins in human tissue treated with compression bandaging have not been reported. The goal of this study was to determine the expression of a wide range of proteases in untreated venous leg ulcer tissue and the changes in these levels after 4 weeks of high‐strength...
