Summary: Preeclampsia is associated with a significant decrease in estrogen levels, which can be normalized by exogenous estradiol administration. The decrease in estrogen levels may be attributed to changes in enzyme activities in the placental trophoblast cells. Activation of the estrogenic G-protein-coupled receptor 30 (GPR30) has protective effects on the placenta. Estrogens play a role in improving placental perfusion through various mechanisms.

Summary: This study aimed to clarify the changes in nitric oxide (NO) metabolism during the course of preeclampsia (PE). By measuring the concentrations of stable NO metabolites, nitrite and nitrate (NOx), it was found that NOx concentrations were significantly lower in PE patients compared to the control group, suggesting that impairment of NO metabolism may play an important role in the pathogenesis of PE.

Summary: Preeclampsia is a pregnancy-specific condition that causes maternal and fetal morbidity and mortality and is believed to be related to abnormal placental development or dysfunction. Common comorbidities such as chronic hypertension, diabetes, autoimmune conditions, kidney disease, and obesity are associated with an increased risk of preeclampsia, but the exact mechanisms are not well understood. This review examines mouse models of chronic hypertension, pregestational diabetes, and obesity that develop preeclampsia-like symptoms and discusses their relevance to the human condition. The authors propose the development of mouse models that incorporate chronic comorbidities to improve preclinical testing.

Summary: SARS-CoV-2 infection causes severe symptoms in COVID-19 patients, including lung tissue damage and multiple organ failure. The drug naltrexone has been found to suppress the release of inflammatory cytokines and inhibit viral replication and infectivity. It may also interfere with the interaction between the virus spike protein and the host receptor ACE2. Therefore, naltrexone could be a potential treatment for COVID-19.

Summary: The BCR is composed of a membrane-bound Ig and a heterodimer of CD79A and CD79B. CD79 subunits mediate intracellular propagation of BCR signals critical for B cell development, survival, and activation. This study generated knockin mice expressing chimeric CD79 and demonstrated their utility in preclinical analysis of anti-human CD79 therapy. Anti-human CD79 treatment prevented disease development in mouse models of autoimmunity and inhibited antibody secretion by terminally differentiated plasma cells in vitro.

Summary: The study identified alpha 1-microglobulin as a key constituent in CICs from IgAN patients, which was associated with mesangial cell injury and aberrant glycosylated IgA1 binding. Elevated levels of circulating IgA-alpha 1-microglobulin complex were detected in an independent IgAN population and were correlated with hypertension, eGFR levels, and Oxford T-scores in these patients. Detection of circulating IgA-alpha 1-microglobulin complex may serve as a potential noninvasive biomarker for IgAN.

Summary: Hypertension poses a threat to society due to unknown causes, hindering proper management and affecting a growing number of patients. It is a high-risk factor for stroke, cardiac and renal complications, and disability. Soluble factors play an important role in the pathophysiology of hypertension, with potential neural effects that are not well understood in conditions such as preeclampsia. Shedding light on the central effect of these factors may advance our understanding and management of hypertension in preeclampsia.

Summary: With the increasing lifespan and societal changes, women are now able to marry and have children later than in previous centuries. However, pathogenic genetic variants in the population can cause female subfertility or infertility before the average age of menopause, leading to counter-selection of these harmful alleles. It is speculated that as a logical consequence, menopause may occur later and women's reproductive lifespan may be extended. Factors such as medical interventions and lifestyle also play a role in female fertility.

Summary: Through analyzing the expression of non-coding genes in trophoblast fusion and placental diseases, key roles of miR-193b and UCA1 in cell function and gene expression have been identified. Knocking down UCA1 leads to the dysregulation of important trophoblast physiology genes, while in cells overexpressing STOX1B, the effects of UCA1 down-regulation are alleviated.

Summary: In pregnancies complicated by preeclampsia (PE) and fetal growth restriction (FGR), iron homeostasis is altered, with iron levels significantly correlating with the severity of the diseases. The normal increase in plasma volume during pregnancy is less in PE and FGR, which has a different impact on factors like iron concentration compared to normal pregnancies. Excess iron may promote ferroptosis, contributing to trophoblast stress and lipotoxicity.

Summary: This study examined the concentrations of scavenger proteins in the plasma of pregnant women and fetuses with and without corpus luteum in preeclampsia. The results showed that maternal haemopexin levels were higher in IVF pregnancies with corpus luteum and lower in IVF pregnancies without corpus luteum compared to naturally conceived pregnancies. Maternal alpha(1)-microglobulin levels were higher in severe cases of preeclampsia without corpus luteum compared to naturally conceived pregnancies and IVF pregnancies with corpus luteum. In cord blood, haemopexin levels were higher in IVF pregnancies with corpus luteum compared to naturally conceived pregnancies in preeclampsia and alpha(1)-microglobulin levels were higher in IVF pregnancies without corpus luteum compared to IVF pregnancies with corpus luteum in the normotensive population.

Summary: Preeclampsia, a severe pregnancy-related inflammatory disease, lacks effective treatment. The role of dysbiosis in the gut microbiome and fungal flora has been suggested in preeclampsia and other inflammatory diseases. However, dysbiosis in preeclampsia has not been studied in a Scandinavian population, and the potential anti-inflammatory properties of fungal flora have not been explored. A study on preeclamptic and healthy third-trimester women revealed differences in fungal diversity and abundance of certain bacterial taxa, suggesting a potential role in the pathophysiology of preeclampsia.
