In this study, we identify emodin-a bioactive anthraquinone derived from <i>Rheum palmatum</i> (radix Rhei) and <i>Polygonum cuspidatum</i> (Polygonaceae)-as a potent and selective inhibitor of NLRP3 inflammasome activation. Notably, emodin disrupts the assembly of the NLRP3 complex without impairing inflammasome priming. Transcriptomic profiling via RNA sequencing reveals that emodin reprograms mitochondrial quality control pathways, markedly enhancing mitophagy flux. Mechanistically, emodin suppresses casein kinase II (CK2)-mediated phosphorylation of FUNDC1, a pivotal mitophagy receptor, thereby promoting mitochondrial clearance and preventing mitochondrial reactive oxygen species-induced NLRP3 inflammasome assembly. Both genetic silencing of FUNDC1 and pharmacological inhibition of mitophagy with 3-methyladenine abrogated abrogate the inhibitory effects of emodin, establishing a direct mechanistic link between FUNDC1-dependent mitophagy and NLRP3 regulation. <i>In vivo</i>, emodin confers significant protection in sepsis models, with these protective effects being lost in NLRP3-deficient mice or upon macrophage-specific deletion of FUNDC1.

Recent studies have increasingly highlighted the pivotal role of astrocytes in the initiation and progression of neurocognitive dysfunction. Alterations in astrocytic morphology and functionality have been strongly associated with the onset of cognitive impairments, positioning astrocytes as key regulators in neurocognitive processes. Astrocytes influence neurocognitive function through their involvement in the uptake and release of gliotransmitters, modulation of inflammatory mediators, and metabolic regulation. These processes have been implicated in various neurodegenerative and neurocognitive disorders, including epilepsy, Alzheimer's disease, postoperative cognitive dysfunction, and sepsis-associated encephalopathy. Given the emerging role of astrocytes in these conditions, understanding the mechanisms by which they modulate neurocognitive function is essential for identifying potential therapeutic targets. This review provides an overview of the current understanding of astrocytic contributions to neurocognitive dysfunction and explores the therapeutic opportunities provided by the targeting of astrocyte-mediated pathways.</p>","PeriodicalId":13762,"journal":{"name":"International Journal of Biological Sciences","volume":"21 7","pages":"3122-3143"},"PeriodicalIF":8.2,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12080396/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144093467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
