- The study used single-cell and spatial transcriptomics to analyze placental tissues from late-onset preeclampsia (LOPE) and healthy pregnancies.
- It identified a distinct SPP1+ extravillous trophoblast (EVT) subtype linked to necroptosis, an inflammatory cell death pathway, as a key feature in LOPE.
- Spatial analysis showed SPP1+ EVTs are localized near macrophages, with the SPP1-CD44 signaling axis mediating their interaction.
- In a mouse model, Mlkl knockout reduced preeclampsia-like symptoms and SPP1 expression, supporting the role of necroptosis in LOPE.
- The findings suggest necroptosis as a therapeutic target and SPP1 as a potential biomarker for LOPE pathogenesis.
