title: Association of monocyte chemotactic protein-1 and CC chemokine receptor 2 gene variants with preeclampsia.
abstract: Preeclampsia complicates 10% of pregnancies in developing countries. It is one of the leading causes of maternal and fetal/neonatal mortality and morbidity worldwide. It has been suggested that maladaptation of the maternal immune response during pregnancy might be a causal factor for preeclampsia. According to immune maladaptation hypothesis, preeclampsia is due to an inappropriate regulation of normally Th2-deviated maternal immune responses, leading to a shift toward harmful Th1 immunity. Several studies indicate that monocyte chemotactic protein-1 (MCP-1) and CC chemokine receptor 2 (CCR2) are involved in Th1 and Th2 immunity. In this study, we investigated the association between MCP-1 A-2518G and CCR2-V64I polymorphisms and preeclampsia. One hundred eighty preeclamptic pregnant women and 145 healthy controls were included in the study. We observed that in preeclamptic women, MCP-1 G: CCR2 Val haplotype was significantly higher when compared with other haplotypes. In conclusion, we stated that MCP-1 and CCR2 gene variants might be associated with preeclampsia.
