Abstract

INTRODUCTION: Preeclampsia (PE) and fetal growth restriction (FGR) are among the leading causes of perinatal morbidity and mortality. Placental insufficiency is central to these conditions. The mechanisms underlying placental insufficiency are poorly understood. Apoptosis has long been considered the only form of regulated cell death, recent research has identified an alternate process of programmed cell death known as necroptosis [1]. Necroptosis is distinct from apoptosis, relying on the deacetylase sirtuin-2 [2], receptor interacting kinases RIPK1 and 3, and the pseudokinase MLKL [3]. We aimed to determine whether these key necroptosis effector molecules were present in human placenta and..
