A closer look at decidual tissue with trophoblast and maternal leukocytes in proximity showed that the expression intensity of NLRP3 and IL-1β was significantly increased in preeclampsia without FGR compared to normal pregnancies (NLRP3 P = 0.017 and IL-1β P = 0.031) (Figures 4E,F). Here, NLRP3 is linked to preeclampsia.
