Abstract

Spontaneous preterm birth is the leading cause of neonatal mortality and morbidity globally. Activation of the maternal immune system leads to a downstream cascade of proinflammatory events that culminate in the activation of spontaneous uterine contractions and the rupture of the foetal membranes. Anti-inflammatory agents may be a novel therapeutic approach to prevent inflammation-induced myometrial contractions and premature rupture of foetal membranes. The polyphenol gallic acid has been previously shown to exert potent anti-inflammatory effects. Thus, this study aimed to determine the effect of gallic acid on proinflammatory and pro-labour mediators in cytokine-stimulated gestational tissues in vitro. In primary human cells isolated from myometrium and foetal membranes (decidua, and amnion mesenchymal and epithelial cells), gallic acid treatment suppressed inflammation-induced expression of proinflammatory cytokines and chemokines and extracellular matrix-degrading and matrix-remodelling enzymes. Gallic acid also significantly inhibited inflammation-induced myometrial activation as evidenced by decreased expression of contraction-associated proteins, the uterotonic PGF2α and collagen cell contractility. Using a global prote...Continue Reading
