title: Modulation of monocytes matrix metalloproteinase-2, MT1-MMP and TIMP-2 by interferon-gamma and -beta: implications to multiple sclerosis.
abstract: Recent findings have implicated the activity of matrix metalloproteinases (MMPs) in the pathogenesis of multiple sclerosis (MS), while in vivo interferon (IFN)-beta treatment was demonstrated to suppress MMPs. In the present study, the effects mediated by IFN-gamma and IFN-beta on the mRNA and protein expression of MMP-2, its physiological activator, MT1-MMP and its endogenous inhibitor, TIMP-2, by monocytes were evaluated in vitro. The results point to the significance of IFNs in modulating MMPs/tissue inhibitors of MMPs (TIMPs) expression, and support the possibility that the therapeutic effects of IFN-beta may be, in part, due to induction of a shift from "pro-" to "anti-proteolytic" pattern of MMPs and TIMPs expression.
