Changed mechanical stress (σ) and oxidative stress may trigger TNF-α, TGF-β, and MMP. TNF-α stimulated the matrix metalloproteinases (MMP) and inhibit the tissue inhibitors of metalloproteinases (TIMP). In a result, MMP degrades collagens, but TIMP and myofibroblast inhibit collagen degradation and promote collagen synthesis, finally determine collagen ECM remodeling.
