Proteases target many substrates, triggering changes in distinct biological
processes correlated with cell migration, EMT/EndMT and fibrosis. Extracellular
protease activity, demonstrated by secreted and membrane-bound protease forms,
leads to ECM degradation, activation of other proteases (i.e., proteolysis of
nonactive zymogens), decomposition of cell-cell junctions, release of sequestered
growth factors (TGF-? and VEGF), activation of signal proteins and receptors,
degradation of inflammatory inhibitors or inflammation-related proteins, and
changes in cell mechanosensing and motility. Intracellular proteases, mainly
caspases and cathepsins, modulate lysosome activity and signal transduction
pathways. Herein, we discuss the current knowledge on the multidimensional impact
of proteases on the development of fibrosis.
