TLR9 and preeclampsia: RT-qPCR confirmed aberrant expression of genes involved in inflammation and stress response (TLR4 and TLR9) and also genes involved in host defense (PRDX5, MIF, CD74, NFE2L1, and CSF3R), suggesting that preeclampsia sera suppress the TLR4/9-dependent excess oxidative stress in adipose tissue.
