Inhibition of the p38 MAPK pathway attenuates renal injury in pregnant rats with acute necrotizing pancreatitis.

Immunol Res 2021 May 14. Epub 2021 May 14.

Department of General Surgery, Renmin Hospital of Wuhan University, Wuhan, 430060, Hubei Province, People's Republic of China.

The p38 mitogen-activated protein kinase (MAPK) pathway is an important intracellular signalling pathway that leads to increased expression of pro-inflammatory mediators. Our previous studies have shown that the p38 MAPK pathway was changed in the acute renal injury (ARI) in acute pancreatitis in late pregnancy (APIP), whereas the role of p38 MAPK in APIP-induced ARI has been poorly understood. The present study was undertaken to investigate the participation of the p38 MAPK signalling pathway and the protective effect of SB203580, an inhibitor of p38 MAPK in ARI in APIP. Read More

Maternal microvascular dysfunction during preeclamptic pregnancy.

Clin Sci (Lond) 2021 May;135(9):1083-1101

Department of Health and Human Physiology, University of Iowa, IA, U.S.A.

Preeclampsia is a hypertensive disorder of pregnancy effecting ∼5-8% of pregnancies in the United States, and ∼8 million pregnancies worldwide. Preeclampsia is clinically diagnosed after the 20th week of gestation and is characterized by new onset hypertension accompanied by proteinuria and/or thrombocytopenia, renal insufficiency, impaired liver function, pulmonary edema, or cerebral or visual symptoms. This broad definition emphasizes the heterogeneity of the clinical presentation of preeclampsia, but also underscores the role of the microvascular beds, specifically the renal, cerebral, and hepatic circulations, in the pathophysiology of the disease.
