Well-served for this role by a large network of afferent and efferent connections, the mouse insula can be simplified into an anterior, medial and posterior portion. Here we focus on the medial subregion, a once over-looked area that has gained recent attention for its involvement in an array of behaviours. Although the connections of medial insular cortex neurons have been previously identified, their precise glutamatergic phenotype remains undefined (typically defined by the presence of the subtype of vesicular glutamate transporters). Hence, we combined Cre knock-in mouse lines and adeno-associated viral tracing to distinguish between the expression of the two major vesicular glutamate transporters, type 1 (vGlut1) and 2 (vGlut2), in the subregion's neuronal inputs and outputs. Our results determined that the medial insula has extensive glutamatergic efferents expressing both vGlut1 and vGlut2 throughout the neuraxis. In contrast, a more conservative number of glutamatergic inputs were observed, with exclusively vGlut2+ projections received from hypothalamic and thalamic regions. Taken together, we demonstrate that vGlut1- and vGlut2-expressing networks of this insular subdivision have distinct connectivity patterns, including a greater abundance of vGlut1+ fibres innervating hypothalamic regions and the extended amygdala. These findings provide insight into the distinct chemo-architecture of this region, which may facilitate further investigation into the role of the medial insula in complex behaviour.</p>","PeriodicalId":8806,"journal":{"name":"Biochemical pharmacology","volume":" ","pages":"116637"},"PeriodicalIF":5.3,"publicationDate":"2024-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142674925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Andrographolide (AP), a multifunctional natural terpenoids derived from <em>Andrographis paniculate</em>, has been suggested to play beneficial roles in metabolic disorders-associated disease. Here, we reported that AP effectively counteracts tubule injury and interstitial fibrosis in mice fed with a long-term high-fat diet (HFD). AP treatment decreased HFD-induced lipid accumulation in kidney parenchyma and attenuated lipotoxicity-mediated oxidative stress and mitochondrial dysfunction, resulting in a marked decrease in tubular cell senescence. Importantly, AP inhibited senescence-associated secretory phenotype (SASP) secretion by senescent tubular cells, and in turn suppressed proliferation and activation of fibroblasts in a paracrine effect. Furthermore, we revealed that AP functions as an AMP-activated protein kinase (AMPK) activator to ameliorate renal lipid accumulation through coordinately modulating AMP-activated protein kinase AMPK target genes. By stimulation of AMPK activity, AP protects injured kidney against tubular cell senescence and fibroblast activation. These results suggest the potential therapeutic application of AP in the prevention and treatment of CKD, highlighting the promising drug strategy of targeting the lipotoxicity-mediated premature senescence in tubular cells.</div></div>","PeriodicalId":8806,"journal":{"name":"Biochemical pharmacology","volume":"230 ","pages":"Article 116615"},"PeriodicalIF":5.3,"publicationDate":"2024-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142613998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
