NOD1 and NOD2 regulate proinflammatory and prolabor mediators in human fetal membranes and myometrium via nuclear factor-kappa B

Abstract

Preterm birth remains one of the most important issues facing perinatal medicine today, with chronic inflammation and/or infection being the biggest etiological factor. The nucleotide oligomerization domain (NOD) intracellular molecules recognize a wide range of microbial products as well as other intracellular danger signals, thereby initiating inflammation through activation of nuclear factor KB (NFKB), a central regulator of the terminal processes of human labor and delivery. The aims of this study were to determine the effect of 1) human labor, proinflammatory cytokines, and bacterial endotoxin LPS on NOD1 and NOD2 expression and 2) NOD1 and NOD2 activation on the expression of prolabor ..
