Immune dysregulation, particularly T-cell imbalances and pro-inflammatory cytokines, is implicated in vasospasm development. Soluble immune checkpoint proteins—CTLA-4 (sCTLA-4) and PD-L1 (sPD-L1)—regulate immune homeostasis and may serve as biomarkers or modulators of inflammation in aSAH. This prospective cohort study included 179 aSAH patients, divided into sVP+ (n = 48) and sVP− (n = 131), plus 50 healthy controls. Serum sCTLA-4 and sPD-L1 levels were measured on days 1, 5, and 9 post-ictus using Luminex xMAP. Associations with clinical outcomes were analyzed using non-parametric statistics and hierarchical clustering. Both sCTLA-4 and sPD-L1 were significantly elevated in sVP+ patients versus sVP− and controls, increasing over time. sCTLA-4 was significantly higher in sVP+ on days 5 (p = 0.001) and 9 (p < 0.001), and sPD-L1 on days 5 and 9 (both p < 0.001).

Tight junction proteins, claudin-3 (CLDN3) and claudin-5 (CLDN5), are key regulators of BBB integrity and may serve as biomarkers of hemorrhage severity. Methods: In this prospective cohort study, 200 patients with aSAH were evaluated. Serum CLDN3 and CLDN5 levels were measured on days 1, 5, and 9 post-ictus and compared with healthy and aneurysm-bearing controls. Patients were stratified by modified Fisher Score (mFS), World Federation of Neurosurgical Societies (WFNS) score, and 3-month modified Rankin Scale (mRS). Associations with complications, including delayed cerebral ischemia (DCI) and infection, were also assessed. Results: CLDN3 and CLDN5 levels were significantly elevated in aSAH patients compared to controls ( p <0.01 and p <0.0001, respectively), with CLDN5 levels consistently higher than CLDN3 at all time points ( p <0.0001). CLDN5 levels were consistently higher than CLDN3 at all measured time points, and neither CLDN3 nor CLDN5 showed significant temporal variation between days 1, 5, and 9. Both markers showed significant positive correlation with mFS, with higher levels observed in mFS3 and mFS4 groups ( p <0.05 to p <0.0001). No association was found between CLDN3 and 5 levels and WFNS score, 3-month mRS, age, sex, comorbidities, inflammatory markers, or DCI. Conclusion: Elevated serum CLDN3 and especially CLDN5 levels reflect hemorrhage extent and potential BBB disruption in aSAH. Their strong correlation with mFS suggests utility in grading imageological hemorrhagic severity, though not in predicting long-term functional outcomes. CLDN5 emerges as a promising biomarker for early assessment of BBB integrity in neurovascular injury.}, year = {2025}, eissn = {1437-2320}, orcid-numbers = {Szebeni, Gábor/0000-0002-6998-5632} } @article{MTMT:36391088, title = {The effect of baricitinib on pSTAT3 levels in IL-6- or IL-15-stimulated PBMCs isolated from patients with SLE}, url = {https://m2.mtmt.hu/api/publication/36391088}, author = {Szebeni, Gábor and Gémes, Nikolett and Neuperger, Patricia and Szabó, Enikő and Balog, József Ágoston and Honfi, Dániel György and Balog, Attila and Toldi, Gergely}, doi = {10.3389/fimmu.2025.1675350}, journal-iso = {FRONT IMMUNOL}, journal = {FRONTIERS IN IMMUNOLOGY}, volume = {16}, unique-id = {36391088}, issn = {1664-3224}, year = {2025}, eissn = {1664-3224}, orcid-numbers = {Szebeni, Gábor/0000-0002-6998-5632; Toldi, Gergely/0000-0003-0178-1243} } @article{MTMT:36444224, title = {Potential anticancer effects of Peganum harmala in human papillomavirus-related cervical and head and neck cancer cells}, url = {https://m2.mtmt.hu/api/publication/36444224}, author = {Abdallah, Hiba Faroug Muddather and Nasibova, Tohfa and Szebeni, Gábor and Gémes, Nikolett and Bózsity-Faragó, Noémi and Minorics, Renáta and Garayev, Eldar and Orhan, Ilkay Erdogan and Herbette, Gaëtan and Schelz, Zsuzsanna and Hohmann, Judit and Zupkó, István}, doi = {10.3389/fphar.2025.1668827}, journal-iso = {FRONT PHARMACOL}, journal = {FRONTIERS IN PHARMACOLOGY}, volume = {16}, unique-id = {36444224}, year = {2025}, eissn = {1663-9812}, orcid-numbers = {Abdallah, Hiba Faroug Muddather/0000-0001-8472-330X; Szebeni, Gábor/0000-0002-6998-5632; Minorics, Renáta/0000-0001-9685-813X; Schelz, Zsuzsanna/0000-0002-8519-4830; Hohmann, Judit/0000-0002-2887-6392; Zupkó, István/0000-0003-3243-5300} } @article{MTMT:36444923, title = {C > U mutations generate immunogenic peptides in SARS-CoV-2}, url = {https://m2.mtmt.hu/api/publication/36444923}, author = {Balogh, Gergő Mihály and Koncz, Balázs and Asztalos, Leó and Ari, Eszter and Gémes, Nikolett and Szebeni, Gábor and Papp, Benjamin Tamás and Tóth, Franciska and Papp, Balázs and Pál, Csaba and Manczinger, Máté}, doi = {10.1038/s41467-025-65251-8}, journal-iso = {NAT COMMUN}, journal = {NATURE COMMUNICATIONS}, volume = {16}, unique-id = {36444923}, abstract = {The rapid spread of SARS-CoV-2 worldwide has given rise to numerous variants. While the impact of viral mutations on antibody escape has been extensively studied, an unresolved issue concerns how emerging mutations shape HLA-restricted T-cell immune responses. Here, we analyse SARS-CoV-2 genomic variants, showing that 27% of the mutations are C > U transitions, a phenomenon common in human RNA viruses and primarily attributed to APOBEC3 enzyme-driven mutagenesis. We find that this mutation bias generally enhances viral peptide binding to human leukocyte antigen class I (HLA-I) molecules, producing immunogenic epitopes that trigger cytotoxic adaptive immune responses in most individuals across diverse populations. We also identify several HLA-I variants that are especially well-suited for presenting viral epitopes generated by these mutations. Intriguingly, individuals carrying these specific alleles are predominantly located in South and East Asia. Finally, we show that carrying HLA-I molecules that are less likely to bind C > U-induced viral peptides increases risk for severe COVID-19 disease. Our work suggests a link between C > U hypermutation and HLA-I-based presentation of viral epitopes, which may reflect the evolutionary outcome of ancient RNA virus pandemics. More broadly, our findings imply that SARS-CoV-2 diversification leads to ongoing gains of T-cell epitopes despite natural selection favouring immune escape.}, year = {2025}, eissn = {2041-1723}, orcid-numbers = {Ari, Eszter/0000-0001-7774-1067; Szebeni, Gábor/0000-0002-6998-5632; Tóth, Franciska/0009-0005-7338-8231; Manczinger, Máté/0000-0003-0831-9617} } @article{MTMT:34840255, title = {Identification of immune subsets with distinct lectin binding signatures using multi-parameter flow cytometry: correlations with disease activity in systemic lupus erythematosus}, url = {https://m2.mtmt.hu/api/publication/34840255}, author = {Szabó, Enikő and Faragó, Anna and Bodor, Gergely and Gémes, Nikolett and Puskás, László and Kovács, László and Szebeni, Gábor}, doi = {10.3389/fimmu.2024.1380481}, journal-iso = {FRONT IMMUNOL}, journal = {FRONTIERS IN IMMUNOLOGY}, volume = {15}, unique-id = {34840255}, issn = {1664-3224}, abstract = {Cell surface glycosylation can influence protein-protein interactions with particular relevance to changes in core fucosylation and terminal sialylation. Glycans are ligands for immune regulatory lectin families like galectins (Gals) or sialic acid immunoglobulin-like lectins (Siglecs). This study delves into the glycan alterations within immune subsets of systemic lupus erythematosus (SLE).MethodsEvaluation of binding affinities of Galectin-1, Galectin-3, Siglec-1, Aleuria aurantia lectin (AAL, recognizing core fucosylation), and Sambucus nigra agglutinin (SNA, specific for α-2,6-sialylation) was conducted on various immune subsets in peripheral blood mononuclear cells (PBMCs) from control and SLE subjects. Lectin binding was measured by multi-parameter flow cytometry in 18 manually gated subsets of T-cells, NK-cells, NKT-cells, B-cells, and monocytes in unstimulated resting state and also after 3-day activation. Stimulated pre-gated populations were subsequently clustered by FlowSOM algorithm based on lectin binding and activation markers, CD25 or HLA-DR.ResultsElevated AAL, SNA and CD25+/CD25- SNA binding ratio in certain stimulated SLE T-cell subsets correlated with SLE Disease Activity Index 2000 (SLEDAI-2K) scores. The significantly increased frequencies of activated AALlow Siglec-1low NK metaclusters in SLE also correlated with SLEDAI-2K indices. In SLE, activated double negative NKTs displayed significantly lower core fucosylation and CD25+/CD25- Siglec-1 binding ratio, negatively correlating with disease activity. The significantly enhanced AAL binding in resting SLE plasmablasts positively correlated with SLEDAI-2K scores.ConclusionAlterations in the glycosylation of immune cells in SLE correlate with disease severity, which might represent potential implications in the pathogenesis of SLE.}, year = {2024}, eissn = {1664-3224}, orcid-numbers = {Kovács, László/0000-0003-4457-1430; Szebeni, Gábor/0000-0002-6998-5632} }
