Interleukin (IL)11 is a crucial regulator during the initiation of pregnancy in humans and mice. Elevated levels are detected in serum, placenta and decidua of women with pre-eclampsia. Elevated IL11 during placentation recapitulates pre-eclampsia in mice, although withdrawal rescues pre-eclampsia features, suggesting that IL11 could provide a novel therapeutic target. The aim of this study was to determine the safety profile of an IL11 antagonist ligated to polyethylene glycol (PEGIL11A) during pregnancy in mice. Blocking IL11 signalling during mid to late gestation pregnancy in mice did not affect pregnancy viability, or alter placental or fetal weight, or morphology. Importantly, decidual..
