Why does a high-fat diet induce preeclampsia-like symptoms in pregnant rats?

摘要

Changes in neurotransmitter levels in the brain play an important role in epilepsy-like attacks after pregnancy-induced preeclampsia-eclampsia. Metabotropic glutamate receptor 1 participates in the onset of lipid metabolism disorder-induced preeclampsia. Pregnant rats were fed with a high-fat diet for 20 days. Thus, these pregnant rats experienced preeclampsia-like syndromes such as hyper-tension and proteinuria. Simultaneously, metabotropic glutamate receptor 1 mRNA and protein ex-pressions were upregulated in the rat hippocampus. These findings indicate that increased expres-sion of metabotropic glutamate receptor 1 promotes the occurrence of high-fat diet-induced pree-clampsia in pregnant rats.
