Other cytotoxic molecules, including granzymes A, H, K, and M, were variably expressed across tissues, and memory CD8+ T cells targeting persistent viruses expressed multiple granzymes coordinately. In an in vitro tonsil system, transforming growth factor-\u03b2 induced discordant regulation of cytotoxic molecules and CD103. Combined with interleukin-15, this circuitry modulated proliferation and the acquisition of redirected killing activity via perforin and granzyme B.

MAIT cells represent a large pre-expanded T cell subset in humans and are involved in both protective immunity and inflammatory immunopathology. However, what controls the functional heterogeneity of human MAIT cell responses is still largely unclear. Here, combining functional and transcriptomic analyses, we investigate how MAIT cell response programs are influenced by the cytokine milieu at the time of antigen recognition. Activation by MR1-presented antigen together with IL-12 induces intermediate levels of IFN\u03b3 and TNF, as well as a regulatory profile with substantial IL-10 production and elevated expression of TIM-3, LAG-3, and PD-1. Activation by the combination of antigen and IL-12 induces a c-MAF-dependent program required for IL-10 production. The MAIT cell-derived IL-10 mediates both autocrine and paracrine immune regulation. In contrast, coactivation of MAIT cells with IL-18 induces IL-17, GM-CSF, IFN\u03b3, and TNF, without IL-10. Notably, IL-18 dominantly counteracts IL-10 expression. The activation states biased toward IL-10 or IL-17 production are reversible and do not represent stable subsets. Finally, MR1-restricted TCR-mediated activation without cytokine coactivation drives primarily granzyme B cytolytic arming. Altogether, these findings demonstrate that human MAIT cells adapt their functional effector response during antigen recognition to cytokine cues in the microenvironment, and identify programs biased toward either regulatory c-MAF-dependent IL-10 expression, or an inflammatory IL-17 and GM-CSF profile.", "doi": "10.1073/pnas.2414230122", "pmid": "39903121", "labels": {"National Genomics Infrastructure": "Service", "NGI Stockholm (Genomics Production)": "Service", "NGI Short read": "Service"}, "xrefs": [{"db": "pmc", "key": "PMC11831165"}], "notes": [], "created": "2025-11-21T14:09:08.705Z", "modified": "2025-11-21T14:09:09.031Z"}, {"entity": "publication", "iuid": "de5f9b658ce74f6096b9c352ea946d5b", "links": {"self": {"href": "https://publications.scilifelab.se/publication/de5f9b658ce74f6096b9c352ea946d5b.json"}, "display": {"href": "https://publications.scilifelab.se/publication/de5f9b658ce74f6096b9c352ea946d5b"}}, "title": "SARS-CoV-2 and HSV-1 Induce Amyloid Aggregation in Human CSF Resulting in Drastic Soluble Protein Depletion.", "authors": [{"family": "Christ", "given": "Wanda", "initials": "W", "orcid": "0000-0003-3886-5248", "researcher": {"href": "https://publications.scilifelab.se/researcher/38fe3a44fdb547b885cce5b6f490b2bc.json"}}, {"family": "Kapell", "given": "Sebastian", "initials": "S", "orcid": "0000-0001-9304-558X", "researcher": {"href": "https://publications.scilifelab.se/researcher/cffd944f88e54ed6a910183ba49ef656.json"}}, {"family": "Sobkowiak", "given": "Michal J", "initials": "MJ", "orcid": "0000-0003-2932-1994", "researcher": {"href": "https://publications.scilifelab.se/researcher/14f1eb990edf472cac56f24d7cae330c.json"}}, {"family": "Mermelekas", "given": "Georgios", "initials": "G"}, {"family": "Evertsson", "given": "Bj\u00f6rn", "initials": "B"}, {"family": "Sork", "given": "Helena", "initials": "H", "orcid": "0000-0002-5390-4420", "researcher": {"href": "https://publications.scilifelab.se/researcher/f5d08dad4f2d4ee0a3e3a8f060383da5.json"}}, {"family": "Saher", "given": "Osama", "initials": "O"}, {"family": "Bazaz", "given": "Safa", "initials": "S"}, {"family": "Gustafsson", "given": "Oskar", "initials": "O"}, {"family": "Cardenas", "given": "Eduardo I", "initials": "EI"}, {"family": "Villa", "given": "Viviana", "initials": "V"}, {"family": "Ricciarelli", "given": "Roberta", "initials": "R"}, {"family": "Sandberg", "given": "Johan K", "initials": "JK", "orcid": "0000-0002-6275-0750", "researcher": {"href": "https://publications.scilifelab.se/researcher/7468c415a46645a3a4c3d28badcff954.json"}}, {"family": "Bergquist", "given": "Jonas", "initials": "J", "orcid": "0000-0002-4597-041X", "researcher": {"href": "https://publications.scilifelab.se/researcher/d745034529f3423abbea230b4e586d20.json"}}, {"family": "Sturchio", "given": "Andrea", "initials": "A"}, {"family": "Svenningsson", "given": "Per", "initials": "P", "orcid": "0000-0001-6727-3802", "researcher": {"href": "https://publications.scilifelab.se/researcher/5199496295334771ba3c5621a83a6f43.json"}}, {"family": "Malm", "given": "Tarja", "initials": "T", "orcid": "0000-0002-9530-7472", "researcher": {"href": "https://publications.scilifelab.se/researcher/c1ab3c9695424308b07c375901a089f4.json"}}, {"family": "Espay", "given": "Alberto J", "initials": "AJ"}, {"family": "Pernemalm", "given": "Maria", "initials": "M", "orcid": "0000-0003-4624-031X", "researcher": {"href": "https://publications.scilifelab.se/researcher/f15f303cb2044cfa81719700137e3603.json"}}, {"family": "Lind\u00e9n", "given": "Anders", "initials": "A"}, {"family": "Klingstr\u00f6m", "given": "Jonas", "initials": "J", "orcid": "0000-0001-9076-1441", "researcher": {"href": "https://publications.scilifelab.se/researcher/95c1b345ae434fb383b7fe6a1d053c80.json"}}, {"family": "El Andaloussi", "given": "Samir", "initials": "S", "orcid": "0000-0003-4468-9113", "researcher": {"href": "https://publications.scilifelab.se/researcher/bd1036a42043441da3e444f4eac58010.json"}}, {"family": "Ezzat", "given": "Kariem", "initials": "K", "orcid": "0000-0003-4186-0675", "researcher": {"href": "https://publications.scilifelab.se/researcher/6f2f1d3d8a5d467c8fc3b95388e4c606.json"}}], "type": "journal article", "published": "2024-11-20", "journal": {"title": "ACS Chem Neurosci", "issn": "1948-7193", "volume": "15", "issue": "22", "pages": "4095-4104", "issn-l": "1948-7193"}, "abstract": "The corona virus (SARS-CoV-2) pandemic and the resulting long-term neurological complications in patients, known as long COVID, have renewed interest in the correlation between viral infections and neurodegenerative brain disorders. While many viruses can reach the central nervous system (CNS) causing acute or chronic infections (such as herpes simplex virus 1, HSV-1), the lack of a clear mechanistic link between viruses and protein aggregation into amyloids, a characteristic of several neurodegenerative diseases, has rendered such a connection elusive. Recently, we showed that viruses can induce aggregation of purified amyloidogenic proteins via the direct physicochemical mechanism of heterogeneous nucleation (HEN). In the current study, we show that the incubation of HSV-1 and SARS-CoV-2 with human cerebrospinal fluid (CSF) leads to the amyloid aggregation of several proteins known to be involved in neurodegenerative diseases, such as APLP1 (amyloid \u03b2 precursor like protein 1), ApoE, clusterin, \u03b12-macroglobulin, PGK-1 (phosphoglycerate kinase 1), ceruloplasmin, nucleolin, 14-3-3, transthyretin, and vitronectin. Importantly, UV-inactivation of SARS-CoV-2 does not affect its ability to induce amyloid aggregation, as amyloid formation is dependent on viral surface catalysis via HEN and not its ability to replicate. Additionally, viral amyloid induction led to a dramatic drop in the soluble protein concentration in the CSF. Our results show that viruses can physically induce amyloid aggregation of proteins in human CSF and result in soluble protein depletion, thus providing a potential mechanism that may account for the association between persistent and latent/reactivating brain infections and neurodegenerative diseases.", "doi": "10.1021/acschemneuro.4c00636", "pmid": "39510798", "labels": {"Bioinformatics Support,

Both intestinal CD39high and hepatic CD56+ adaptations accumulated with donor age. CD56+ MAIT cells displayed limited T cell receptor-repertoire breadth, elevated MR1 binding, and a transcriptional profile skewed toward innate activation pathways. Furthermore, CD56 was dynamically up-regulated to a persistent steady-state equilibrium after exposure to antigen or IL-7.

In this study, we longitudinally track human CD8+ T cell clones expanding in response to yellow fever virus (YFV) vaccination at the single-cell level. We observed a drop in clonal diversity in blood from the acute to memory phase, suggesting that clonal selection shapes the circulating memory repertoire. Clones in the memory phase display biased differentiation trajectories along a gradient from stem cell to terminally differentiated effector memory fates. In secondary responses, YFV- and influenza-specific CD8+ T cell clones are poised to recapitulate skewed differentiation trajectories.

inflammation of the lower airways. The balance of protective versus pathological immune responses in COVID-19 is incompletely understood. Mucosa-associated invariant T (MAIT) cells are antimicrobial T cells that recognize bacterial metabolites, and can also function as innate-like sensors and mediators of antiviral responses. Here, we investigated the MAIT cell compartment in COVID-19 patients with moderate and severe disease, as well as in convalescence. We show profound and preferential decline in MAIT cells in the circulation of patients with active disease paired with strong activation. Furthermore, transcriptomic analyses indicated significant MAIT cell enrichment and pro-inflammatory IL-17A bias in the airways. Unsupervised analysis identified MAIT cell CD69high and CXCR3low immunotypes associated with poor clinical outcome. MAIT cell levels normalized in the convalescent phase, consistent with dynamic recruitment to the tissues and later release back into the circulation when disease is resolved.

responses in COVID-19 is important to decipher mechanisms of host responses and interpret disease pathogenesis. Natural killer (NK) cells are innate effector lymphocytes that respond to acute viral infections but might also contribute to immunopathology. Using 28-color flow cytometry, we here reveal strong NK cell activation across distinct subsets in peripheral blood of COVID-19 patients. This pattern was mirrored in scRNA-seq signatures of NK cells in bronchoalveolar lavage from COVID-19 patients. Unsupervised high-dimensional analysis of peripheral blood NK cells furthermore identified distinct NK cell immunotypes that were linked to disease severity. Hallmarks of these immunotypes were high expression of perforin, NKG2C, and Ksp37, reflecting increased presence of adaptive NK cells in circulation of patients with severe disease. Finally, arming of CD56bright NK cells was observed across COVID-19 disease states, driven by a defined protein-protein interaction network of inflammatory soluble factors. This study provides a detailed map of the NK cell activation landscape in COVID-19 disease.", "doi": "10.1126/sciimmunol.abd6832", "pmid": "32826343", "labels": {"Affinity Proteomics Stockholm": "Service", "Bioinformatics Support for Computational Resources": "Service"}, "xrefs": [{"db": "pii", "key": "5/50/eabd6832"}, {"db": "pmc", "key": "PMC7665314"}], "notes": [], "created": "2020-12-10T16:30:00.149Z", "modified": "2024-01-16T13:48:41.915Z"}, {"entity": "publication", "iuid": "aa033e622fbc43ffb6090c29ba97d1a8", "links": {"self": {"href": "https://publications.scilifelab.se/publication/aa033e622fbc43ffb6090c29ba97d1a8.json"}, "display": {"href": "https://publications.scilifelab.se/publication/aa033e622fbc43ffb6090c29ba97d1a8"}}, "title": "The viral protein corona directs viral pathogenesis and amyloid aggregation.", "authors": [{"family": "Ezzat", "given": "Kariem", "initials": "K", "orcid": "0000-0003-4186-0675", "researcher": {"href": "https://publications.scilifelab.se/researcher/6f2f1d3d8a5d467c8fc3b95388e4c606.json"}}, {"family": "Pernemalm", "given": "Maria", "initials": "M", "orcid": "0000-0003-4624-031X", "researcher": {"href": "https://publications.scilifelab.se/researcher/f15f303cb2044cfa81719700137e3603.json"}}, {"family": "P\u00e5lsson", "given": "Sandra", "initials": "S"}, {"family": "Roberts", "given": "Thomas C", "initials": "TC"}, {"family": "J\u00e4rver", "given": "Peter", "initials": "P"}, {"family": "Dondalska", "given": "Aleksandra", "initials": "A"}, {"family": "Bestas", "given": "Burcu", "initials": "B"}, {"family": "Sobkowiak", "given": "Michal J", "initials": "MJ"}, {"family": "Lev\u00e4nen", "given": "Bettina", "initials": "B"}, {"family": "Sk\u00f6ld", "given": "Magnus", "initials": "M"}, {"family": "Thompson", "given": "Elizabeth A", "initials": "EA"}, {"family": "Saher", "given": "Osama", "initials": "O"}, {"family": "Kari", "given": "Otto K", "initials": "OK"}, {"family": "Lajunen", "given": "Tatu", "initials": "T", "orcid": "0000-0001-6234-9193", "researcher": {"href": "https://publications.scilifelab.se/researcher/55d9cb27b0734ca496514762ed1627f0.json"}}, {"family": "Sverremark Ekstr\u00f6m", "given": "Eva", "initials": "E", "orcid": "0000-0001-6271-8681", "researcher": {"href": "https://publications.scilifelab.se/researcher/d7519ea4bf1f43dcab124c3d62b489db.json"}}, {"family": "Nilsson", "given": "Caroline", "initials": "C"}, {"family": "Ishchenko", "given": "Yevheniia", "initials": "Y"}, {"family": "Malm", "given": "Tarja", "initials": "T"}, {"family": "Wood", "given": "Matthew J A", "initials": "MJA"}, {"family": "Power", "given": "Ultan F", "initials": "UF", "orcid": "0000-0003-3246-3774", "researcher": {"href": "https://publications.scilifelab.se/researcher/e0d135555da74520a0d4b7733cd6ddd7.json"}}, {"family": "Masich", "given": "Sergej", "initials": "S"}, {"family": "Lind\u00e9n", "given": "Anders", "initials": "A"}, {"family": "Sandberg", "given": "Johan K", "initials": "JK", "orcid": "0000-0002-6275-0750", "researcher": {"href": "https://publications.scilifelab.se/researcher/7468c415a46645a3a4c3d28badcff954.json"}}, {"family": "Lehti\u00f6", "given": "Janne", "initials": "J", "orcid": "0000-0002-8100-9562", "researcher": {"href": "https://publications.scilifelab.se/researcher/8406a97bac744a59b1bc951978994581.json"}}, {"family": "Spetz", "given": "Anna-Lena", "initials": "AL", "orcid": "0000-0003-3964-9512", "researcher": {"href": "https://publications.scilifelab.se/researcher/70270e32d48d486799cc9dd61e36a4f1.json"}}, {"family": "El Andaloussi", "given": "Samir", "initials": "S"}], "type": "journal article", "published": "2019-05-27", "journal": {"volume": "10", "issn": "2041-1723", "issue": "1", "pages": "2331", "title": "Nat Commun", "issn-l": "2041-1723"}, "abstract": "Artificial nanoparticles accumulate a protein corona layer in biological fluids, which significantly influences their bioactivity. As nanosized obligate intracellular parasites, viruses share many biophysical properties with artificial nanoparticles in extracellular environments and here we show that respiratory syncytial virus (RSV) and herpes simplex virus type 1 (HSV-1) accumulate a rich and distinctive protein corona in different biological fluids. Moreover, we show that corona pre-coating differentially affects viral infectivity and immune cell activation. In addition, we demonstrate that viruses bind amyloidogenic peptides in their corona and catalyze amyloid formation via surface-assisted heterogeneous nucleation. Importantly, we show that HSV-1 catalyzes the aggregation of the amyloid \u03b2-peptide (A\u03b242), a major constituent of amyloid plaques in Alzheimer's disease, in vitro and in animal models. Our results highlight the viral protein corona as an acquired structural layer that is critical for viral-host interactions and illustrate a mechanistic convergence between viral and amyloid pathologies.", "doi": "10.1038/s41467-019-10192-2", "pmid": "31133680", "labels": {"Global Proteomics and Proteogenomics": "Technology development", "Bioinformatics Support for Computational Resources": "Service"}, "xrefs": [{"db": "pii", "key": "10.1038/s41467-019-10192-2"}, {"db": "pmc", "key": "PMC6536551"}], "notes": [], "created": "2020-01-07T12:31:23.818Z", "modified": "2024-01-16T13:48:44.332Z"}]}
