Although the expression of matrix metalloproteinase-12 (MMP-12) appears to be increased in most inflammatory diseases, the role of this enzyme in the pathogenesis of toxoplasmosis in pregnant women, if any, is unknown. In a recent study in Taiwan, the serum concentrations of MMP-12 and its substrate elastin were evaluated in pregnant women with Toxoplasma gondii infection. Compared with the healthy pregnant and non-pregnant women used as controls, the pregnant women with toxoplasmosis had significantly higher serum concentrations of MMP-12 and significantly higher levels of elastin synthesis and degradation. Interaction between MMP-12 and elastin in the serum samples was confirmed by co-immunoprecipitation. It seems possible that MMP-12 may contribute to elastin degradation occurring during the pathogenesis of toxoplasmosis in pregnant women.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
