A Dynamic Peripheral Immune Landscape During Human Pregnancy

Chinese Academy of Sciences — Mon, 14 Apr 2025 10:50:07 EST

This study uncovers dynamic immune adaptations during pregnancy through single-cell RNA sequencing of peripheral blood mononuclear cells at different pregnancy stages. A gradual reduction in cytotoxicity of T and NK cells, along with decreased MHC-II and CD40 signaling in T and B cells, suggests weakened adaptive immunity. Meanwhile, upregulated pro-inflammatory genes in monocytes may compensate for this reduction. Late pregnancy shows a transition toward immune activation in dendritic and CD4+ T cells. Notably, we highlight a novel pro-aging effect of pregnancy, which may reverse postpartum. These findings enhance our understanding of pregnancy immunity and its impact on disease risk.
