As a key mediator involved in infection and immunity, it has been reported that sepsis patients are accompanied by increased heat shock protein 70 (HSP70). Trained immunity is a novel innate immunity approach that can be activated by β-glucan to fight against sepsis. The mechanism of HSP70 activating trained macrophages against sepsis needs further elucidation. Trained immunity and sepsis models were established by β-glucan and LPS individually both in vivo and in vitro. We demonstrated that HSP70 was significantly upregulated in septic mice serum, and HSP70 could protect mice from sepsis by activating β-glucan-trained macrophages as an ideal secondary inducer via TLR2-NF-κB pathway. Additionally, the sepsis resistant effects of HSP70 could be blocked by its antibody. In summary, more than a molecular chaperone to maintain homeostasis, HSP70 could be an important trained immunity inducer to help the body fighting against sepsis, which provided new stimuli for trained immunity and novel therapeutic solutions for sepsis.</div></div>","PeriodicalId":297,"journal":{"name":"Cytokine","volume":"187 ","pages":"Article 156861"},"PeriodicalIF":3.7,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142997493","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The cytokine interleukin-33 (IL-33) plays significant roles in immune responses, and has been associated with inappropriate allergic reactions, autoimmune diseases, and cancer pathology. In the past decade, studies have begun to uncover the pivotal roles of IL-33 in shaping tumour microenvironment (TME), where it may promote or inhibit tumorigenesis and development depending on the specific tumour types. However, the association between IL-33 expression and UCEC remains unclear. Here we investigated the expression profiles of IL-33 in pan-cancer based on TCGA database. Then, differential gene expression analysis and correlation analysis of IL-33 was investigated in UCEC. In addition, functional enrichment analysis and Kaplan–Meier survival analysis were performed to predict the potential function of IL-33 and its role in the prognosis of UCEC patients. Also, a nomogram model was constructed to predict the prognosis of UCEC. The expression of the inflammatory factor NF-κB p65 and the IL-33, along with its receptor ST2, was analyzed in UCEC tumour tissues and normal tissues of clinical specimens through immunohistochemical staining. Meanwhile, we used toluidine blue staining and methanol Congo red staining to observe the infiltration of mast cells and eosinophils in the endometrial tissue. The results of Kaplan–Meier plotter data indicated that patients with lower IL-33 expression had poorer progression-free interval than those with higher expression. Based on the results of multifactor Cox regression, a nomogram was generated to predict UCEC occurrence risk and prognosis. Clinical specimen characteristics also confirmed a negative correlation between IL-33 expression and UCEC staging and grading.
