MLKL and preeclampsia: A mild to moderate negative correlation between placental 25(OH)D and trophoblast RIPK3 (-0.352, p = 0.003), endothelial RIPK3 (r = -0.244, p = 0.03), and trophoblast MLKL (r = -0.296, r - 0.011) were observed.<h4>Conclusion</h4>Lower placental 25(OH)D concentration is associated with an increased placental necroptosis activity in preeclampsia.
