The intestinal microbiome plays a crucial role in health, but its influence on immune adaptation to pregnancy remains unclear. Bacterial extracellular vesicles (BEVs), released by gut bacteria, can cross the intestinal barrier and modulate immune responses. In our study we investigated the effect of fecal EVs (fEVs) from pregnant women on Th cell composition in vitro. fEVs were purified from preserved stool samples, characterized, and their uptake by immune cells was analyzed. Using an in vitro T cell culture model, we examined Th cell phenotypes, intracellular cytokine expression, and proteomic changes after stimulation with fEVs from pregnant and non-pregnant women. We demonstrate that fEVs from preserved stool samples are rapidly taken up by T cells and modulate their phenotype. Stimulation with fEVs from pregnant women shifts Th cells toward a regulatory profile favorable for pregnancy, increasing Th2 cells while reducing Th17 cells compared to fEVs from non-pregnant controls. This study provides the first in vitro evidence that fecal-derived EVs influence immune adaptation to pregnancy and may offer a basis for microbiome-targeted strategies to prevent or treat immunological pregnancy complications.","PeriodicalId":165,"journal":{"name":"European Journal of Immunology","volume":"55 9","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eji.70056","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145084625","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}

To elucidate microenvironment-specific differences in antitumor responses, we established patient-derived ex vivo tumor-lung slices. We analyzed immune activation profiles after treatment with anti-CD3/CD28 and the checkpoint inhibitor Nivolumab. Lung slices from non-tumor, tumor-adjacent, tumor-border, and tumor-central tissue were generated and assessed for viability, cell composition, and immune competence via flow cytometry, soluble factor secretion, and bulk RNA-sequencing. The tumor-border contained the highest number of immune cells (8.3-fold vs. non-tumor), secreted tumor markers (S100 and CA15-3), and exhibited high levels of inflammatory mediators (IFNγ, IL-6, and IL-2). Treatment with anti-CD3/CD28 increased the frequency of CD137+/CD8+ T cells and induced cytokine responses dominated by IFNγ, IL-2, and Granzyme B. While both non-tumor and tumor-border tissue responded to anti-CD3/CD28, the intensities of immune responses were highly varied. Notably, treatment with Nivolumab induced an inflammatory response primarily in the tumor-border evidenced by IFNγ, IL-2, and Perforin secretion alongside increased expression of CD107a on CD8+ T cells, in a donor-dependent manner. Taken together, these data demonstrate how tumor-border tissue slices can be utilized to study T cell responses in the context of the patient-specific tumor microenvironment.","PeriodicalId":165,"journal":{"name":"European Journal of Immunology","volume":"55 9","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eji.70060","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145058005","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}

Recent advances in single-cell multiomics, refined mouse models, and human cohort studies have deepened insights into their TCR–ligand interactions, developmental pathways, and context-dependent functions. This mini-review synthesizes current understanding from structural studies of γδ TCR recognition and developmental regulation—including inborn errors of immunity—to adaptive-like clonal expansions shaped by infection, aging, and environmental cues. It also highlights their dual roles in cancer, where subsets can exert potent cytotoxicity or promote tumor progression, and discusses strategies to optimize their antitumor potential through checkpoint blockade, metabolic modulation, and engineered receptors. Beyond immunity to malignancy, γδ T cells contribute to tissue homeostasis, repair, and regulation of inflammatory processes in diverse organs, influencing outcomes in neuroinflammation, autoimmunity, and fibrotic diseases. Together, these perspectives form the foundation of a special issue in the European Journal of Immunology (https://onlinelibrary.wiley.com/doi/toc/10.1002/(ISSN)1521-4141.T-cells) dedicated to advancing the understanding of γδ T cell biology and clinical potential.","PeriodicalId":165,"journal":{"name":"European Journal of Immunology","volume":"55 9","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eji.70058","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145058004","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}

Recent studies have highlighted nutrients as a key fourth signal in modulating T cell immunity. T cell metabolism is integral to regulating cell proliferation, survival, and differentiation. Dysregulation of nutrient metabolism, including glucose, amino acids, and lipids, has been considered a crucial determinant of T cell activation, differentiation, and function, and may lead to the disease progression of autoimmune disorders, including systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), and multiple sclerosis (MS).

Extracellular vesicles (EVs), including exosomes and microvesicles, have emerged as key players in LTx because of their roles in immune regulation, inflammation, and antigen presentation. EVs carry immunologically active molecules such as MHC class I/II proteins, cytokines, and lung self-antigens (SAgs), suggesting their involvement in infections and both AR and CLAD. Recent studies indicate that EVs have diagnostic and prognostic potential. EVs expressing HLA-G and SAgs correlate with graft outcomes, while circulating EV-associated miRNAs are being evaluated as noninvasive biomarkers of rejection. In addition to their diagnostic potential, mesenchymal stem cell-derived EVs show promise in managing PGD by reducing inflammation, mitigating ischemia‒reperfusion injury, and enhancing lung repair. In conclusion, EVs contribute to pathogenesis, have potential as biomarkers, and hold promise as tools for improving LTx outcomes as therapeutic agents, yet further research is needed to validate their clinical application in the prediction and management of CLAD.","PeriodicalId":165,"journal":{"name":"European Journal of Immunology","volume":"55 9","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eji.70042","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145012363","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}

Deregulated or excessive activation of the IL-1 system is associated with detrimental inflammatory reactions. Beside signaling receptors, IL-1-family receptors comprise decoy or negative regulatory receptors, which regulate cell activation mediated by IL-1 family ligands. IL-1-family negative regulatory receptors, which include IL-1R8 and IL-1R2, have peculiar structural features and functions essential to the self-regulation of the IL-1 system. IL-1R8 and IL-1R2 emerge as regulatory molecules whose function is context-dependent, spanning from negative regulation of inflammation in infections or conditions of sterile inflammation and cell damage, including cancer-related inflammation, to skewing of myeloid and lymphoid cells, modulation of anti-tumor immunity, and immune checkpoint activity.
