KLF6 Downregulation-Mediated Loss of LILRB4 Impairs Decidual Macrophage Tolerance During Toxoplasma gondii Infection
This study reveals that *Toxoplasma gondii* infection impairs maternal-fetal tolerance and causes adverse pregnancy outcomes by suppressing the pSTAT3/KLF6 axis, which downregulates LILRB4 on decidual macrophages and disrupts the IDO/iNOS immunoregulatory balance.
