Abstract

Natural killer (NK) cells, which have an essential role in immune defense, also contribute to reproductive success. NK cells are abundant at the maternal–fetal interface, where soluble HLA-G is produced by fetal trophoblast cells during early pregnancy. Soluble HLA-G induces a proinflammatory response in primary, resting NK cells on endocytosis into early endosomes where its receptor, CD158d, resides. CD158d initiates signaling through DNA-PKcs, Akt, and NF-κB for a proinflammatory and proangiogenic response. The physiological relevance of this endosomal signaling pathway, and how activation of CD158d through soluble ligands regulates NK cell fate and function is unknown. We show here that CD158d agonists trigger a DNA damage response signaling pathway involving cyclin-dependent kinase inhibitor p21 expression and heterochromatin protein HP1-γ phosphorylation. Sustained activation through CD158d induced morphological changes in NK cell shape and size, and survival in the absence of cell-cycle entry, all hallmarks of senescence, and a transcriptional signature of a senescence-associated secretory phenotype (SASP). SASP is a program that can be induced by oncogenes or DNA damage, and promotes growth arrest and tissue repair. The secretome of CD158d-stimulated senescent NK cells promoted vascular remodeling and angiogenesis as assessed by functional readouts of vascular permeability and endothelial cell tube formation. Retrospective analysis of the decidual NK cell transcriptome revealed a strong senescence signature. We propose that a positive function of senescence in healthy tissue is to favor reproduction through the sustained activation of NK cells to remodel maternal vasculature in early pregnancy.

  • Trophoblast senescence is physiological, progresses with gestation and peaks at term; senescence is also described in maternal decidual cells and fetoplacental membranes, where it promotes parturition and placental detachment at term.

    “In addition to trophoblast senescence, which is a physiological phenomenon that progresses with gestation and peaks at term, senescence is also extensively described in maternal decidual cells and fetoplacental membranes, where it has a pivotal role in the promotion of parturition and detachment of the placenta from the uterus at term257–262.”

    From SenNet recommendations for detecting senescent cells in different tissues (2024) · cites this paper as [262]

    The section on CD158d activation reports a senescence signature in decidual NK cells during weeks 6–12 of pregnancy, and the paper proposes a reproductive role through vascular remodeling in early pregnancy. It does not establish senescence of trophoblasts or fetoplacental membranes, progression or a peak at term, or a role in parturition or placental detachment. (LLM, conf=0.84)

  • Cellular senescence has physiological roles during development, in adult megakaryocytes, syncytiotrophoblasts, wound healing and placental natural killer lymphocytes.

    “Apart from its beneficial role as an anti-tumour response, physiological roles for cellular senescence have also been identified during development [15,16], in adult megakaryocytes, syncytiotrophoblasts, wound healing and placental natural killer lymphocytes [17,18,19].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
