Helicobacter pylori and gastritis: the role of extracellular matrix met al.loproteases, their inhibitors, and the
disintegrins and met al.loproteases--a systematic literature review.
These cells are able to produce and secrete mediator molecules such as cytokines, chemokines, growth-factors, enzymes, and
disintegrins, which activate endothelial cells, proliferation of smooth muscle cells, and lesion progression, and contribute to the weakening of a vulnerable plaque by matrix degradation of its fibrous cap.
In addition, two separate
disintegrins and metalloproteinases with thrombospondin motifs (ADAMTS-1 and ADAMTS-4) are highly expressed in an SIV model [82].
L-Selectins are cleaved from the cell surface by the action of ADAM17 (
disintegrins and metalloproteinase 17) or TACE (TNF-[alpha] converting enzyme), a process known as "shedding," which may dramatically regulate migratory cell behaviour [35].
In particular, common rattlesnake (Crotalus and Sistrurus genera) venom components include metalloproteinases, serine proteases, phospholipases [A.sub.2] (PL[A.sub.2]s), L-amino acid oxidases (LAAOs), Cysteine-Rich Secretory Proteins (CRISPs), C-type lectin-like,
disintegrins and vasoactive peptides [5,6,10].
Epigallocatechin-3-gallate (EGCG), a GA derivative, was found to inhibit degradation of human cartilage proteoglycan and type II collagen, and selectively inhibits ADAMTS-1, ADAMTS-4, and ADAMTS-5 (
disintegrins and metalloproteinases with thrombospondin motifs) (37,38).
Matrix-degrading proteases ADAMTS4 and ADAMTS5 (
disintegrins and metalloproteinases with thrombospondin motifs 4 and 5) are expressed in human glioblastomas.
