Interleukin 22 prevents lipopolysaccharide- induced preterm labor in mice†

Essential role for IL-10 in resistance to lipopolysaccharide-induced preterm labor in mice.

IL-10 is highly expressed in the uterus and placenta and is implicated in controlling inflammation-induced pathologies of pregnancy. To investigate the role of IL-10 in regulating preterm labor, the response of IL-10 null mutant mice to low-dose LPS in late gestation was evaluated. When IL-10 null mutant C57BL/6 (IL-10(-/-)) and control (IL-10(+/+)) mice were administered LPS on day 17 of pregn...

Role of Notch signaling during lipopolysaccharide-induced preterm labor.

Notch signaling pathways exert effects throughout pregnancy and are activated in response to TLR ligands. To investigate the role of Notch signaling in preterm labor, Notch receptors (Notch1-4), its ligand Delta-like protein-1, transcriptional repressor hairy and enhancer of split-1, and Notch deregulator Numb were assessed. Preterm labor was initiated on gestation d 14.5 by 1 of 2 methods: 1) ...

Nanocurcumine Ameliorates Lipopolysaccharide-induced Depressive-like Behavior in Mice

Objective(s): Curcumin, a plant alkaloid from Curcuma longa, possess antioxidant and anti-inflammatory properties. Recently, the antidepressant activities of curcumin were reported. Nevertheless, bioavailability of curcumin limits its therapeutic utility. Nanotechnology is a developing field that potentially enhances bioavailability and the plasma concentration of curcumin. This study investiga...

Enhanced expression of transient receptor potential channel 3 in uterine smooth muscle tissues of lipopolysaccharide-induced preterm delivery mice

Objective(s): We aimed to investigate the influence of transient receptor potential channel 3 (TRPC3) on lipopolysaccharide-induced (LPS) preterm delivery mice. Materials and Methods: Mice were randomly assigned to the four groups: an unpregnant group, a mid-pregnancy group (E15), a term delivery group, and an LPS-induced preterm delivery group (intraperitoneal injection LPS at 15 days). Uterin...
