Changes in expression levels of immune cells and inflammatory cytokines in pre-eclampsia patients before and after delivery

•By analyze the expression levels of immune cells and cytokines secreted by preeclampsia patients before and after delivery, it is found that PE patients may reduce CD4 + cells and CD8 + cells, and down-regulate the level of cytokines (especially TNF-β) secreted by Th1 cells to reduce the maternal rejection of embryos, thereby reducing the risk of premature delivery, which is a protective adaptive compensation mechanism in favor of embryos.
