Additionally, puerarin administration suppresses ER stress by down-regulation of ATF6, ATF4, CHOP, GRP78 expressions in epididymal white adipose tissue (eWAT), along with decreased phosphorylation IRE1α, PERK, and eIF2α.

However, the specific mechanisms through which these lipids impact cognition remain unclear.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods and results</h3>\u0000 \u0000 <p>This study examines the direct physiological impact of polar lipid supplementation, in the form of buttermilk powder, on primary cortical neuron growth and maturation. The changes are measured with postsynaptic current response recordings, immunohistochemical examination of functional synapse localization and numbers, and the biochemical quantification of receptors responsible for neuronal synaptic neurotransmission. Chronic exposure to polar lipids increases primary mouse cortical neuron basal excitatory synapse response strength attributed to enhanced dendritic complexity and an altered expression of the excitatory α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor subunit 2 (GluR2).</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>The present finding suggests that dietary polar lipids improve human cognition through an enhancement of neuronal maturation and/or function.</p>\u0000 </section>\u0000 </div>","PeriodicalId":212,"journal":{"name":"Molecular Nutrition & Food Research","volume":"68 15","pages":""},"PeriodicalIF":4.5,"publicationDate":"2024-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141562218","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
