Metabolic reprogramming driven by impaired trophoblasts and decidual XCR1+PMN-MDSCs crosstalk controls adverse outcomes in advanced maternal age
Listed in NCBI GEO
Decidual polymorphonuclear myeloid-derived suppressor cells (PMN-MDSCs) are crucial for maternal–fetal stability and accumulate to support fetal development.
Description
Although advanced maternal age (AMA) increases the risk of adverse outcomes, the regulatory role and mechanism of decidual PMN-MDSCs in these outcomes remain unclear. Herein, the XCL1–XCR1 interaction mediated specific crosstalk between trophoblast cells and decidual PMN-MDSCs in both humans and mice.
Single-cell sequencing identified a decidual PMN-MDSCs subset highly expressing XCR1 markedly reduced in AMA. Impaired XCL1-stimulated decidual XCR1+PMN-MDSCs delayed fetal growth in AMA and Xcr1-/- pregnant mice. Perinatal XCL1 supplementation and oltipraz treatment rescued these functions by activating decidual XCR1+PMN-MDSCs in AMA mice, not Xcr1-/- pregnant mice.

The XCL1–XCR1 axis induced FOXO1 nuclear localization, regulating oxidative phosphorylation-related targets and enabling metabolic processes. Hence, XCL1–XCR1 crosstalk between trophoblast cells and PMN-MDSCs is critical in driving metabolic reprogramming of decidual XCR1+PMN-MDSCs and controlling adverse outcomes caused by AMA.
