The pro-inflammatory cytokine family interleukin (IL)-1 is crucial in CKD with the key alarmin IL-1α playing an additional role as an adhesion molecule that facilitates immune cell tissue infiltration and consequently inflammation. Here, we investigate calcium ion and reactive oxygen species (ROS)-dependent regulation of different aspects of IL-1α-mediated inflammation. We show that human CKD monocytes exhibit altered purinergic calcium ion signatures. Monocyte IL-1α release was reduced when inhibiting P2X7, and to a lesser extent P2X4, two ATP-receptors that were found upregulated compared to monocytes from healthy people. In murine CKD models, deleting P2X7 (P2X7^-/-) abolished IL-1α release but increased IL-1α surface presentation by bone marrow derived macrophages and impaired immune cell infiltration of the kidney without protecting kidney function. In contrast, immune cell infiltration into injured wild type and P2X7^-/- hearts was comparable in a myocardial infarction model, independent of previous kidney injury. Both the chimeric mouse line harboring P2X7^-/- immune cells in wild type recipient mice, and the inversely designed chimeric line showed less acute inflammation. However, only the chimera harboring P2X7^-/- immune cells showed a striking resistance against injury-induced cardiac remodeling. Mechanistically, ROS measurements reveal P2X7-induced mitochondrial ROS as an essential factor for IL-1α release by monocytes. Our studies uncover a dual role of P2X7 in regulating IL-1α biogenesis with consequences for inflammation and inflammation-induced deleterious cardiac remodeling that may determine clinical outcomes in CKD therapies.</p>","PeriodicalId":17801,"journal":{"name":"Kidney international","volume":" ","pages":""},"PeriodicalIF":14.8,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142687327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
