Transmembrane Proteases As Disease Markers and Targets for Therapy

Transmembrane proteases (i.e. membrane-associated proteases, ectoproteases) are present in a wide variety of tissues and cell types including endothelial, epithelial and hematopoietic cells. Natural and synthetic inhibitors have been characterized and have revealed that certain ectoenzymes are able to modulate bioactive peptide responses and to influence major biological events such as cell proliferation, survival and invasiveness. Dysregulated expression of some of them in human diseases triggers research on their role in pathophysiology, on their value as disease markers and as putative targets for therapy.
