High expression of CX3CL1/CX3CR1 at the mother-fetus interface of preeclampsia inhibits trophoblast invasion and migration

Preeclampsia is associated with maternal inflammatory overreaction and imbalanced immunity at the mother-fetus interface. The pro-inflammatory chemokine fractalkine (CX3CL1) is recently recognized apart from imbalanced immunity. In this study, CX3CL1- CX3C chemokine receptor 1(CX3CR1) regulation of decidual macrophage function and trophoblast invasion ability in preeclampsia was initially explored.
