Background: Preeclampsia (PE) is a pregnancy-specific, multisystemic disorder that affects 2-8% pregnancies worldwide and is a leading cause of maternal and perinatal mortality. At present, there is no cure for PE apart from delivery the placenta. Therefore, it is important and urgent to possess a suitable animal model to study the pathology and treatment of PE.

Preeclampsia is one of the most severe obstetric complications, yet its pathogenesis remains unclear. Decidual natural killer (dNK) cells, the most abundant immune cells at the maternal-fetal interface, are closely associated with preeclampsia due to abnormalities in their quantity, phenotype, and function. This review summarizes the molecular mechanisms by which dNK cells regulate extravillous trophoblast (EVT) invasion, promote uterine spiral artery remodeling, and maintain immune tolerance.

Chronic hypertension is an increasingly prevalent condition that constitutes a risk factor for superimposed preeclampsia during pregnancy. In this study, we assessed the gut microbiome in a rat model of superimposed preeclampsia to characterize the microbial signature associated with defective placentation processes identified at the preclinical disease stage. The blood pressure profile, renal function parameters and fetal phenotype were evaluated in pregnant Stroke-prone Spontaneously Hypertensive Rats (SHRSP) and their normotensive controls.

Background: Preeclampsia (PE) is a pregnancy complication characterized by hypertension, proteinuria, endothelial dysfunction, and complement dysregulation. Placenta-derived extracellular vesicles (EVs), necessary in maternal-fetal communication, might contribute to PE pathogenesis. Moreover, neutrophil extracellular traps (NETs) play a pathogenic role in other complement-mediated pathologies, and their contribution in PE remains unexplored.

Hydroxychloroquine (HCQ), a synthetic antimalarial, is recognized for its immunomodulatory, anti-inflammatory and vascular-protective effects. In 20-30% of cases of primary obstetrical antiphospholipid syndrome (APS), the combination of antiplatelet aggregation and prophylactic anticoagulation fails to prevent obstetrical complications, a situation referred to as refractory obstetrical APS. This is partly due to the pro-inflammatory effects of antiphospholipid antibodies (aPL) binding to decidual and trophoblastic cells, which compromise embryonic implantation and placentation.
