Objectives Clinical endometritis is a common reproductive disorder in mammals that seriously
endangers animal health and causes economic losses worldwide. This study aims to use lipopoly
saccharide and Trueperella pyogenes exotoxin as modelling reagents (LC) to perfuse the mouse
uterus in order to establish a model of clinical endometritis and to investigate the anti-inflamma
tory and antioxidant effects of chlorogenic acid (CGA).
Methods In this study, five LC uterine perfusions were selected to model clinical endomet
ritis. The anti-inflammatory and antioxidant effects of CGA were clarified. Through HE staining,
proinflammatory cytokines, blood testing, NFκB and Keap1/Nrf2 signalling pathways and other
index changes to explore the protection mechanism of CGA.
Key findings After CGA treatment, the appearance, inflammatory damage and blood indicators of
the mouse uterus returned to normal. Simultaneously, CGA could inhibit the activation of NFκB
and reduce the release of inflammatory cytokines; CGA could also activate Keap1/Nrf2, promote
the dissociation of Keap1 and Nrf2 and significantly increase the expression of the downstream
genes HO-1 and NQO1.
CGA (purity >98.0%) was purchased from Desite Bio (Chengdu, China).
