Table 1 Expression and Function of Various Matrix Metalloproteinases in Inflammatory Bowel Disease
Figure 1 Schematic view illustrating how a specific matrix metalloproteinase (MMP) (eg, MMP-3 [A]) triggers the conversion of other MMP zymogens (proMMP-7 [B], proMMP-9 [C], or proMMP-13 [D]) to their active forms.

Figure 2 Schematic view of situations in which MMP is either controlled or not by tissue inhibitors of MMPs (TIMPs). (A) In physiological conditions, TIMPs form with MMPs reversible complexes in a 1:1 ratio thereby controlling MMP activity. Within inflammatory microenvironment, the TIMP/MMP ratio can be decreased by overexpression of MMPs without a parallel increase of TIMPs (B), a sudden decrease in the expression of TIMPs (C) or increased MMP concentration that is accompanied by concomitant decrease in TIMP levels (D).
