Our cover features images related to flow cytometry techniques widely used for analysis of function and phenotypes of major human and murine immune cell subsets, superimposed on a multidimensional immune cell population scatter plot. These images are taken from the third edition of EJI’s Flow Cytometry Guidelines by Cossarizza et al., a comprehensive resource prepared … Read more
Spatial Organisation of Tumour cDC1 States Correlates with Effector and Stem‐Like CD8+ T Cells Location. [[{“value”:”Cécile Piot, Mariana Pereira da Costa, Adi Biram, Carlos M. Minutti, Kok Haw Jonathan Lim, Mary Green, Ania Mikolajczak, Robert P. Jenkins, Lucy Meader, Michael D. Buck, Ana Cardoso, Neil Rogers, Erik Sahai, Caetano Reis e Sousa”}]]
Using scRNAseq and spatial analysis, we analyse cDC1 states and spatial distribution in tumours during immune-mediated rejection. We identify two cDC1 activation states, each occupying different regions and associated with distinct CD8+ T cell populations. This reveals the spatial organisation of cDC1 states that may be key to anti-tumour immunity. ABSTRACT CD8+ T cells are … Read more
Immunological Impact of Oncolytic Adenoviruses On Cancer Therapy: Clinical Insights. [[{“value”:”Reza Nadafi, Wenliang Dong, Victor W. van Beusechem”}]]
Conditionally replicating oncolytic adenoviruses (OAds) mediate cancer cell destruction while triggering robust immune responses. Clinical data reveal their ability to remodel the tumor microenvironment and enhance responsiveness when combined with other therapies. This review highlights immune-modulating effects of OAds in patients, with a focus on therapeutic implications and combination strategies. ABSTRACT Oncolytic immunotherapy, particularly using … Read more
Signal Transducer and Activator of Transcription 3 (STAT3) Variant p.K709N Causes Hyper‐IgE Syndrome Likely by Impaired STAT3‐Dimer Formation. [[{“value”:”Beate Hagl, Benedikt D. Spielberger, Betina Neumann, Simon J. Pelham, Dharmendra Pandey, Andreas Schlundt, Camille Barro, Anica Lechner, Christine Wolf, Elissa K. Deenick, Michael Sattler, Stuart G. Tangye, Simon Rothenfusser, Ellen D. Renner”}]]
In a patient with the classical clinical phenotype of STAT3-hyper-IgE syndrome, we identified the previously unreported STAT3 variant p.K709N to be disease-causing. Molecular analyses revealed that STAT3 p.K709N exerts a dominant-negative effect, leading to impaired STAT3 dimerization and reduced STAT3 target gene expression. Source: Created in BioRender. Hagl B. (2025) https://BioRender.com/80tycxp. ABSTRACT STAT3-hyper-IgE syndrome (STAT3-HIES) … Read more
Aging and Viral Evolution Impair Immunity Against Dominant Pan‐Coronavirus‐Reactive T Cell Epitope. [[{“value”:”Lucie Loyal, Karsten Jürchott, Ulf Reimer, Lil Meyer‐Arndt, Larissa Henze, Norbert Mages, Jak Kostrzanowski, Bernhard Reus, Maike Mangold, Beate Kruse, Manuela Dingeldey, Birgit Sawitzki, Janine Michel, Marica Grossegesse, Karsten Schnatbaum, Holger Wenschuh, Andreas Nitsche, Nils Lachmann, Bernd Timmermann, Claudia Giesecke‐Thiel, Julian Braun, Florian Kern, Andreas Thiel”}]]
The immunodominant pan-coronavirus epitope iCope spans amino acids 816–830 within the fusion domain of the SARS-CoV-2 spike glycoprotein. This region exhibits a comparatively low mutation rate, especially when contrasted with the receptor-binding domain (RBD). Antigen-specific T cell responses against iCope are detectable even in unexposed individuals, are modestly enhanced following SARS-CoV-2 infection, and are robustly … Read more
Immunogenicity‐Guided Design of an Acinetobacter baumanii Vaccine. [[{“value”:”Chenghua Zhu, Shuaiyuan Liang, Ning Yang, Shan Li, Jianpeng Xue, Runlu Zhou, Xiuwen Hong, Sixi Chen, Nan Gao, Qiang Du, Jianling Huang, Ganzhu Feng, Xingran Du”}]]
Schematic diagram of DCpep-NM-PLGA-rOmpW preparation and its immunoprotective effects on acute lethal pneumonia. This study developed a biomimetic nanovaccine (DCpep-NM-PLGA-rOmpW) against A. baumannii. The nanoparticle-delivered multiepitope vaccine induced robust Th1/Th17 and antibody responses, demonstrating significant protection in a lethal pneumonia model. ABSTRACT The development of vaccines represents a promising and safe strategy to combat multidrug-resistant … Read more
Machine Learning Reassessment of Serum Immune Factors Shows No Unique Immune Profiles Linked to Disease Outcomes in SARS‐CoV‐2‐infected Patients at Hospital Admittance. [[{“value”:”Stefania Rossi, Imerio Capone, Enrico Cabri, Anna Giabelli, Ilaria Rossoni, Giulia Romagnoli, Stefano M. Santini, Cinzia Marcantonio, Roberto Giuseppetti, Umbertina Villano, Roberto Bruni, Anna R. Ciccaglione, Federica Frasca, Alessandra d’Auria, Ginevra Bugani, Gabriella d’Ettorre, Guido Antonelli, Carolina Scagnolari, Maddalena Fratelli, Lucia Gabriele”}]]
Machine learning analysis of serum immune factors clustered SARS-CoV-2 patients into moderate (balanced-immune-modulation [BIM]) and severe groups; the latter composed of two distinct and opposite immune patterns (down-immune-modulation [DIM] and up-immune-modulation [UIM]). DIM/UIM and BIM clusters show different clinical, laboratory and immune parameters including T and B lymphocytes. ABSTRACT The complex pathophysiology of severe acute … Read more
Ex Vivo Modeling and Pharmacological Modulation of Tissue Immune Responses in Inflammatory Bowel Disease Using Precision‐Cut Intestinal Slices. [[{“value”:”Klaudia Maria Grieger, Valerie Schröder, Susann Dehmel, Vanessa Neuhaus, Dirk Schaudien, Maximillian Fuchs, Helena Linge, Alexander Wagner, Ulf Kulik, Benjamin Gundert, Heiko Aselmann, Armin Braun, Christina Hesse, Katherina Sewald”}]]
Studying local immune responses in IBD remains challenging. This study demonstrates that precision-cut intestinal slices from IBD patients mimic key immunopathological features ex vivo and respond specifically to immune stimuli. This model allows direct pharmacological modulation of patient tissue ex vivo and offers a powerful platform for translational research. ABSTRACT Inflammatory bowel disease (IBD) affects … Read more
LAG3 Marks Activated but Hyporesponsive NK Cells.

NK cells quickly upregulate LAG3 upon activation. LAG3+ NK cells present hallmarks of immune exhaustion. The role of LAG3 in imposing NK cell dysfunction remains to be elucidated. ABSTRACT NK cells are critical for immunosurveillance, yet become dysfunctional when chronically stimulated by virally infected or cancerous cells. This phenomenon is similar to T cell exhaustion … Read more
