Protease wound healing
Webb4 aug. 2024 · Chronic wounds often present with elevated levels of matrix metalloproteinases (MMPs), which carryout proteolysis and inactivate the intrinsic growth factors involved in wound healing [ 10 ]. This may be the reason for which chronic skin wound takes longer time to heal [ 11 ]. WebbAfter the neutrophils migrate into the wound site, they generate oxygen free radicals, which kill phagocytized bacteria, and they release high levels of proteases (neutrophil elastase and neutrophil collagenase) which remove components of the extracellular matrix that were damaged by the injury.

WebbWounds heal in four overlapping phases: haemostasis, inflammation, proliferation and remodelling. [ 1, 2] Phase I: Haemostasis Haemostasis results from the activation of platelets, which initiate the coagulation cascade. Platelets also release substances that initiate and influence wound healing.

Webbprotease activity. This shows that in some non-healing wounds, the excess protease activity was predominantly due to HNE activity, whereas in others, it was mainly due to MMP activity. As such, to deal effectively with excess protease activity in all non-healing wounds it is necessary to be able to reduce both HNE and MMP activity. WebbProteases may persist longer in nonhealing wounds. We sought to investigate whether protease activity, protease inhibitor activity, or their combinations are independent …
