title: Dendritic cells derived from preeclampsia patients influence Th1/Th17 cell differentiation in vitro.
abstract: Immune regulation plays important but as-yet-unclear roles in the development of preeclampsia. This study explored potential contributions to immune regulation by dendritic cells (DCs) derived from peripheral blood of preeclampsia patients on the differentiation of Th1 and Th17 cells. Pregnant women with preeclampsia (n = 73) and healthy pregnant women (n = 80) were included in the study. Peripheral blood samples were collected from each participant, and DCs were derived from peripheral blood mononuclear cells in vitro. The phenotypes of DCs, identified by CD14, CD80, CD83, and CD86 expression, were detected by flow cytometry, and secretion of interleukin-23 (IL-23) into the culture medium by DCs was measured by ELISA. CD4 + T cells were separated by the magnetic beads and subjected to flow cytometry to determine their ability to differentiate to Th1 or Th17 cells. Compared with DCs derived from healthy pregnant women, DCs derived from preeclampsia patients expressed higher levels of CD83, CD80, and CD86 (P < 0.05). Additionally, secretion of IL-23 was higher in DCs derived from the preeclampsia group than from the control group (P < 0.001). DCs derived from preeclampsia patients also had a stronger ability to promote the differentiation of CD4 + T cells into Th1/Th17 cells when cultured with different cytokines (P < 0.01). Thus, altered phenotypes and functions of DCs may promote the abnormal balance of Th1 and Th17 in the development of preeclampsia.
