Multiple studies are beginning to link IL-17 mediated induction of fibroblasts and myofibroblasts and the production of tissue degrading proteases and cytokines [31], [33], [34], [35].
MMP2 or MMP15, or both, are connective tissue degrading enzymes [ 16].
The matrix metalloproteinases (MMPs) are a group of tissue degrading enzymes that may be involved in this ongoing brain destruction.
We performed a study to investigate the role of tissue degrading MMP enzymes in patients who developed paradoxical TB-IRIS.
Moreover, by using cultured cells we could minimise or even avoid using tissue degrading enzymes, which might lead to changes in cell surface molecules.
These cells, usually found in abundance in patchy synovial infiltrates, in patients with very early RA [ 23, 24, 37], secrete tissue degrading proteases.
Certainly, fHAs have the capacity to invoke both an inflammatory response as well as induce synthesis of tissue degrading enzymes when added to chondrocytes in vitro [ 22- 25].
Skin punch biopsies (3 mm) were performed on upper and lower leg skin for measurements of intraepidermal nerve fiber density (IENFD), structural analysis, type 1 procollagen abundance, tissue degrading matrix metalloproteinases (MMPs), and poly(ADP-ribose) (PAR) immunoreactivity.
Bacteria produce numerous extracellular molecules, such as tissue degrading enzymes, iron-scavenging siderophores and sticky polymers to protect surface growing bacteria (biofilms), which are individually costly but benefit the group as a whole (West et al. 2007).
This resulted in a pro-inflammatory feedback loop leading to the induction of pro-inflammatory mediators, such as IL-1β, IL-6 and PGE2 and the tissue degrading enzymes MMP-1 and MMP-3.
