Significance

Preeclampsia is an insidious disease, unique to humans, affecting ∼8% of pregnancies. There are no early detection tests or pharmacological treatments. Impaired placentation is widely accepted to contribute to the pathogenesis. However, the mechanisms remain elusive, given the complications of studying first-trimester placental development in women. A major limitation for the study of new treatments is the lack of available animal models that recapitulate the full spectrum of preeclampsia features. We have developed a mouse model characterized by elevated levels of the cytokine Interleukin-11 (IL11). This study provides evidence of a novel pathway causative of preeclampsia features in vivo . It also provides a novel in vivo mouse model that is useful for preclinical studies to test potential therapeutics.
