title: Inhibition of MMP-dependent chemotaxis and amelioration of experimental autoimmune uveitis with a selective metalloproteinase-2 and -9 inhibitor.
abstract: The chemotaxis of inflammatory cells depends on proteolytic disruption of extracellular matrix components. The metalloproteinases (MMP)-2 and -9 enable T-lymphocytes to pass through basement membranes. Selective inhibition of only MMP-2 and -9 almost completely abolished the ability of lymphocytes to digest collagen. The chemotaxis of lymphocytes was reduced 40%. In our in-vivo model of experimental autoimmune uveitis (EAU), 46% of the animals in the treated group remained disease-free, whereas all animals in the control group developed EAU. The mean activity of the disease was also statistically significantly reduced. The data suggest that selective MMP-2 and -9 inhibition might be a treatment option.
