Microbiota associated with bacterial vaginosis (BV), such as Gardnerella vaginalis, Megasphaera elsdenii, and Prevotella timonensis, replace the health-associated bacterium Lactobacillus crispatus and cause inflammation affecting mucosal integrity and immunity. However, it remains unclear how these BV-associated bacteria modulate immune cells and enhance inflammation. Here, we investigated whether BV-associated bacteria directly affected dendritic cell (DC) function. Notably, P. timonensis but not M. elsdenii induced cell–cell clustering between monocytic cell lines and, importantly, between primary DCs and primary CD4 T cells. Our data indicate that this increased clustering is independent of LFA-1. Moreover, P. timonensis enhanced DC-mediated CD4 T cell proliferation. Altogether, these results suggest that P. timonensis-induced cell–cell clustering contributes to the elevated mucosal inflammation observed during bacterial vaginosis.","PeriodicalId":165,"journal":{"name":"European Journal of Immunology","volume":"55 9","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eji.70051","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144930044","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}

Over the past 15 years, ILCs have emerged as key orchestrators of tissue homeostasis and inflammation. To build upon the early promise of cancer immunotherapies, it is essential to better understand the pathways regulating the composition of, and immunosuppressive mechanisms that dominate many solid cancers and effectively curtail or block T cell responses. Given their residence within most tissues, how these cellular sentinels influence tumour development and progression remains an active area of both discovery and more translationally focused research. By defining precisely how different immunosuppressive pathways form, rationalised immunotherapy combinations can be devised to specifically target these. Current evidence indicates that for each ILC subset, both pro- and anti-tumourigenic roles are possible, likely reflecting local cues within different tissues and contexts. Here, we seek to concisely review some of the prevailing data describing ILC contributions to tumour immunity and highlight some of the challenges that still exist in fully dissecting these mechanisms.","PeriodicalId":165,"journal":{"name":"European Journal of Immunology","volume":"55 9","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eji.70041","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144930045","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}

DCs engulf extracellular DNA released by dying cancer cells, supporting activation of the cGAS-STING pathway and concomitant DC maturation. Extracellular DNA in the tumor microenvironment is primarily derived from cells undergoing uncontrolled necrosis or programmed inflammatory death, such as necroptosis, which can be induced when apoptosis pathways are inhibited. Here, we report that caspase inhibition primes activation of a RIPK1/3, MLKL, and STING signaling axis in DCs, resulting in maturation without the need for any further maturation stimuli such as LPS or TNF-α. Notably, these signaling events do not induce DC death, indicating a nonnecroptotic role of the RIPK1-RIPK3-MLKL pathway and novel crosstalk with the STING pathway. Caspase inhibition in DC/cancer cell co-cultures results in DC maturation, inducing TNF-α secretion, which delivers the co-signal to induce cancer cell necroptosis. In summary, we find a collaborative mechanism of the STING and necroptosis pathway in DC maturation, and that activation of the necroptosis pathway has opposite effects on cancer cells and DCs, proposing a possibility for new targets in cancer immunotherapy.","PeriodicalId":165,"journal":{"name":"European Journal of Immunology","volume":"55 9","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eji.70044","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144930042","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}

Complications arising from viral infections in these age groups can present therapeutic challenges, as most of these individuals have impaired adaptive immunity. Using the T- and B cell-deficient Rag2−/− mice, the mechanisms that mediate protection in immunocompromised hosts during RSV infection can be investigated. RSV-infected Rag2−/− mice showed no symptoms of disease or chronic inflammation in the lungs and airways despite the presence of infectious virus in their lungs several months after infection. Interestingly, Natural Killer (NK) cells, the main innate cells with anti-viral cytotoxic effector functions, were recruited 2 days earlier in the lungs of Rag2−/− mice compared with wildtype mice, resulting in early production of IFN-γ. However, depletion of NK cells did not affect disease severity or viral load. Together, these results suggest that the NK cells are largely dispensable for virus control during primary RSV infection in Rag2−/− mice.","PeriodicalId":165,"journal":{"name":"European Journal of Immunology","volume":"55 9","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eji.70045","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144930097","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}

While these clinical manifestations have been linked to the dysregulation of the adaptive immune response, the underlying immunopathology remains poorly understood due to a lack of suitable animal models. To investigate long-term pulmonary consequences of SARS-CoV-2 infection, we used a genetic cross of 129 mice and C57BL/6 (B6)-K18-hACE2 transgene mice, a model previously shown to survive infection. 129xB6-K18-hACE2 mice or littermate controls were infected with a low dose (5 × 102 PFU) of ancestral SARS-CoV-2. Complete viral clearance and full recovery from weight loss occurred by day 8 post-infection. However, prolonged inflammation in the lung and airways persisted up to day 28 post-infection and was associated with the presence of CD4+ and CD8+ T cells, particularly CD8+ effector T cells. This model may therefore prove valuable for further understanding of drivers of long-term lung inflammation and for testing therapeutic strategies and clinically relevant interventions that can target long-term pulmonary inflammation following SARS-CoV-2 infection.","PeriodicalId":165,"journal":{"name":"European Journal of Immunology","volume":"55 8","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eji.70043","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144894139","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}
