The severity of SARS-CoV-2 varies widely, and collective serum immune factors, evaluated in emergency care patients, have not been shown to correlate with disease progression. We applied a machine learning approach to reassess and define serum immune profiles that could align with clinical laboratory parameters and predict disease outcomes in patients with respiratory virus infections, including those with SARS-CoV-2, seeking emergency care. Sixty-two plasma immune molecules, in a cohort of 67 symptomatic SARS-CoV-2, were analyzed for correlation with antibodies (Abs) to spike (S) and nucleocapsid (N) proteins, as well as with clinical laboratory parameters, to identify early indicators of disease prognosis at hospital admission. This approach allowed us to analyze and cluster unlabeled datasets, delineating three distinct serum immune signatures. Two showed significant and opposite modulations, correlating with poorer disease outcomes, while most patients with moderate disease displayed modest immune factor dysregulation. This highlights the complexity of immune responses in the severity of diseases caused by highly respiratory pathogenic virus like SARS-CoV-2, emphasizing the importance of evaluating overall immune imbalance rather than focusing on a few dysregulated factors.","PeriodicalId":165,"journal":{"name":"European Journal of Immunology","volume":"55 7","pages":""},"PeriodicalIF":4.5,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eji.70001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144695823","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to investigate local immune responses using precision-cut intestinal slices (PCIS) from IBD patients and evaluate immunomodulatory treatment directly in patient tissue ex vivo. PCIS from ileal resections of IBD and non-IBD patients were stimulated with Concanavalin A (ConA) or lipopolysaccharide (LPS). Histological analysis of IBD-derived PCIS showed villus atrophy, infiltration of lymphocytes and macrophages, and RNA analysis revealed upregulation of IL-17 and interferon signaling pathways.

Pimecrolimus treatment led to a marked reduction in the release of IL-2, IL-17A, and IFN-γ, and inhibited the IBD supernatant-induced reduction in transepithelial electrical resistance.

This phenomenon is similar to T cell exhaustion but less characterized, limiting therapeutic interventions. As shown for T cells, NK cells often display an increased expression of immune checkpoint proteins (ICP) following chronic stimulation, and ICP blockade therapies are currently being explored for several cancer types, with remarkable patient benefits. Nevertheless, the nature of ICP expression in NK cells is still poorly documented. In this study, we aimed to identify the conditions that lead to and the phenotype of immune checkpoint LAG3-expressing NK cells. Using various experimental models, we found that LAG3 is expressed by murine NK cells upon activation in different contexts, including in response to cancer and acute viral infections. LAG3 marks a subset of immature, proliferating, and activated cells, which, despite activation, have a reduced capacity to respond to a broad range of stimuli. Further characterization also revealed that LAG3+ NK cells exhibit a transcriptional signature similar to that of exhausted CD8+ T cells. Taken together, our results support the use of LAG3 as a marker of dysfunctional NK cells across diverse chronic and acute inflammatory conditions.","PeriodicalId":165,"journal":{"name":"European Journal of Immunology","volume":"55 7","pages":""},"PeriodicalIF":4.5,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eji.70009","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144687921","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditionally, B cell selection in the bone marrow (BM) has been viewed through the lens of negative selection, eliminating potentially harmful clones. Emerging evidence challenges this perspective, revealing a subset of B suppressor cells (Bsup) that actively regulate immune homeostasis. Unlike conventional negative selection, C1-specific Bsup cells, which recognize collagen type II (Col2), engage Col2-specific regulatory T cells (Tregs) to suppress inflammation in healthy individuals. This suggests that Bsup play a role in both peripheral and central tolerance, akin to Tregs. However, the molecular mechanisms governing Bsup selection, differentiation, and function remain unknown. Understanding how Bsup distinguish homeostatic from pathogenic autoreactivity could transform autoimmune disease treatment, shifting the focus from eliminating autoreactive B cells to harnessing their regulatory potential for precision immunotherapy.","PeriodicalId":165,"journal":{"name":"European Journal of Immunology","volume":"55 7","pages":""},"PeriodicalIF":4.5,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eji.202451720","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144681316","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These attacks may involve immune and inflammatory mechanisms. We compared serum biomarkers indicating vascular integrity, leakage, angiogenesis, coagulation, and inflammation.

Furthermore, evidence was found for a role of IL-17, eosinophil, and neutrophil chemotactic factors, and the activation of these granulocytes was found. MASP-1/C1-INHc indicated early activation of the lectin pathway in ACEi-AE and HistAE, but not in C1-INH-HAE. C1s/C1-INHc and MASP-1/C1INHc ratio was able to discriminate C1-INH-HAE from controls and the other AE types.

Here, we report the molecular mechanisms imparted by the homeobox transcription factor HOXB4 in modulating Th2 and Th9 cell differentiation. We found that Hoxb4 induction in T helper cells was TGF-β-dependent. In Th9 cells, HOXB4 overexpression significantly increased IL-9 secretion, while in Th2 cells, HOXB4 could alter only IL-10 secretion among other type 2 cytokines. Promoter activity analyses revealed that HOXB4 was able to transactivate the Il9 and Il10 proximal promoters, while the Il4 and Il13 promoters were differentially modulated. We observed that HOXB4 could physically interact with the transcription factor PU.1 but not GATA3, and directly bind PU.1 response element on the DNA in Th9 cells. The recruitment of HOXB4 was found to be significantly increased in regulatory regions including cECR and CNS1 (Il9 promoter). Collectively, our findings suggest that HOXB4 works downstream of the TGF-β signalling pathway, associates with PU.1, binds the regulatory regions, and distinctly regulates both Th2 and Th9 cell differentiation.\u0000 </div>","PeriodicalId":165,"journal":{"name":"European Journal of Immunology","volume":"55 7","pages":""},"PeriodicalIF":4.5,"publicationDate":"2025-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144666455","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}

Immunosuppression within the TME significantly hinders the efficacy of cancer immunotherapies. Stromal-rich TMEs, characterised by an abundance of mesenchymal stromal cells (MSCs) and cancer-associated fibroblasts (CAFs), are particularly immunosuppressive and associated with poor responses to conventional and immune-based therapies. Glycans, carbohydrate structures on cell surfaces, are dynamically regulated during tumourigenesis and mediate crucial cell–cell communications through receptor–ligand interactions. Sialylation, the addition of sialic acids to glycans, forms sialoglycans that can engage inhibitory Siglec receptors expressed on immune cells and promote immunosuppressive signalling. Emerging evidence implicates aberrant sialylation in the TME as a key driver of immunosuppression. More recently, sialylation of stromal cells in the TME has been shown to suppress anti-tumor immunity. This review explores the role of sialylation within stromal-rich, immunosuppressive TMEs, focusing on how specific sialic acid/Siglec interactions dictate innate and adaptive immune responses. We discuss the potential of targeting glycoimmune checkpoints to overcome stromal-mediated resistance and enhance anti-tumour immunity.","PeriodicalId":165,"journal":{"name":"European Journal of Immunology","volume":"55 7","pages":""},"PeriodicalIF":4.5,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eji.70000","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144634978","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
