These cells display a remarkable plasticity that can be molded by the different environments that neutrophils confront to protect the host, therefore presenting diverse phenotypes. Actually, pro- and anti-inflammatory neutrophils populations (N1- and N2-like phenotypes) have been described in cancer and inflammatory disorders. However, the identification of N1/N2 neutrophil subtypes in human intracellular bacterial diseases remains unexplored. Here, we characterized neutrophils from tuberculosis (TB) patients presenting distinct immunological status according to their disease severity. TB patients were classified as high or low responders (HR or LR) in accordance with their immunity against Mycobacterium tuberculosis (Mtb). Interestingly, by analyzing the phenotypic and functional characteristics of neutrophils from the two groups of TB patients we demonstrated that HR patient's neutrophils display a pro-inflammatory N1-like phenotype, whereas LR patient's neutrophils show an anti-inflammatory N2-like phenotype. Remarkably, whereas neutrophils from both groups of patients phagocytized MtbH37Rv strain equally, HR TB's neutrophils displayed a significantly increased ability to kill pathogenic Mtb as compared to neutrophils from LR TB patients that presented a diminished capacity of bacterial elimination. Together, our findings suggest the existence of different subtypes of neutrophils in TB patients according to their immune response to Mtb and disease severity, indicating that neutrophils might be promising targets for TB host-directed therapy.","PeriodicalId":16045,"journal":{"name":"Journal of immunology","volume":" ","pages":""},"PeriodicalIF":3.6,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143780282","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A previous study delineated four SLE patient clusters based on autoantibody expression to common antigens. To further assess autoantibody diversity within these clusters, we surveyed serum autoantibody expression using a novel autoantigen discovery technology, the Antigenome Platform. This phage-based system assesses serum antibody interactions with large protein fragments (up to 250 amino acids) spanning approximately 90% of the human genome. Bound autoantibody targets were identified through next-generation sequencing and robust bioinformatics and statistical analysis. Our study revealed 88, 49, 10, and 24 autoantibodies that expand the characterization of four SLE clusters, including 24 autoantibodies that characterize a cluster of patients lacking common autoantibodies by conventional assays. Further, some autoantibodies identified have potential links to patient disease features. Although SLE is characterized by antinuclear antibody expression, a significant proportion of autoantigens (ranging from 28% to 54%) in each cluster localized to the cytoplasm, which suggests extensive autoreactivity beyond targets in the cell nucleus that formed the original basis of clustering. This study identifies new markers to aid in the clustering and understanding of SLE disease subtypes and provides a rationale for elucidating autoantibody expression in SLE beyond antinuclear antibodies.","PeriodicalId":16045,"journal":{"name":"Journal of immunology","volume":" ","pages":""},"PeriodicalIF":3.6,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143780271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is a bimodal disease, starting with an initially virus-driven phase, followed by resolution or ensuing inappropriate immune activation causing severe inflammation that is no longer strictly virus dependent. Humoral immunity is beneficial for preventing or attenuating the early stage, without benefit once the later stage begins. Neutralizing antibodies elicited by natural infection or vaccination are short-lived and highly vulnerable to viral sequence variation. By contrast, cellular immunity, particularly the CD8+ T cell arm, has a role in preventing or attenuating severe disease, is far less susceptible to viral variation, and is longer-lived than antibodies. Finally, an ill-defined phenomenon of prolonged symptoms after acute infection, termed \"long COVID,\" is poorly understood but may involve various immunologic defects that are hyperactivating or immunosuppressive. Remaining issues include needing to better understand the immune dysregulation of severe disease to allow more tailored therapeutic interventions, developing antibody strategies that cope with the viral spike sequence variability, prolonging vaccine efficacy, and unraveling the mechanisms of long COVID to design therapeutic approaches.","PeriodicalId":16045,"journal":{"name":"Journal of immunology","volume":" ","pages":""},"PeriodicalIF":3.6,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143780327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We used a nested case-control study with a 2-yr prospective observation period to examine whether genetic variation is associated with BCG-induced innate immune responses and susceptibility to pediatric TB (N = 134 cases, 516 controls) in BCG-vaccinated infants. Whole blood collected at 10 wk of age from 189 control infants was stimulated with BCG or media and examined with flow cytometry to measure BCG-induced PDL1, CD40, and cytokine expression in myeloid (mDC) and plasmacytoid (pDC) dendritic cells, monocytes, and neutrophils. We used a cellular and clinical GWAS to assess for associations between genetic variants, BCG-induced innate immune responses, and susceptibility to TB. We identified 11 lead genetic variants at genome-wide level significance associated with BCG-induced cytokine and surface expression markers including PDL1 (5 pDCs, 3 mDCs, 1 monocytes), CD40 (1 mDCs), and IL-6 (1 monocytes). An IGLL1 variant (rs2096522) was associated with mDC CD40 expression (P = 1.6e-08) and was also discovered as a significant variant using a gene-based method. In the clinical GWAS, we identified 39 lead variants mapping to 74 genes suggestive of an association with susceptibility to pediatric TB (P < 1e-05), but no variant reached genome-wide significance. One clinical lead variant in the PDE8A region (rs1023844, P = 9.6e-07) was also an eQTL and associated with BCG-induced monocyte PDL1 expression.

Using an intratracheal (i.t.) infection method, we discovered that the respiratory infection route yields differential infection kinetics compared to the widely used intraperitoneal (i.p.) infection method. Remarkably, we find that respiratory infection results in limited dissemination, with the virus being mostly contained in the pulmonary tissue. Importantly, using Rag1, Ly49H, and natural killer (NK) cell-deficient animals, we find that lung conventional NK (cNK) cells play a critical role in preventing MCMV-induced morbidity. Mechanistically, we show that indirect activation of lung NK cells via interleukin (IL)-12 and type 1 interferon (IFN) inflammatory cytokines is dispensable, while direct activation via Ly49H is essential in preventing morbidity from i.t. infection. Additionally, we did not find a significant role for ILC2 or tissue-resident NK (trNK) cells in the prevention of viral dissemination, and we did not observe an increase in the abundance of these cells. These findings uncover an unanticipated role for pulmonary cNK cells in preventing viral dissemination from infected lungs.","PeriodicalId":16045,"journal":{"name":"Journal of immunology","volume":" ","pages":""},"PeriodicalIF":3.6,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143772414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In systemic lupus erythematosus patients, apoptotic debris is found on the surface of FDCs. However, the mechanisms by which FDCs engage the protected autoreactive B cells remain unclear. WD repeat and FYVE domain-containing protein 1 (WDFY1) is an adaptor protein involved in endocytic/vacuolar membrane trafficking. We found that FDCs express a high level of WDFY1, which is required for their IC presentation. C57BL/6 mice deficient in WDFY1 generated significantly lesser titers of anti-dsDNA and anti-chromatin autoantibodies (autoAbs) than WDFY1-sufficient mice receiving an equal amount of CD4+ T cells from bm12 mice in the mouse model of inducible lupus. Decreased autoAb production in WDFY1-deficient mice correlates with less GC formation and fewer T and GC B cells in the follicle. Interestingly, T cells from WDFY1-KO mice remain capable of inducing comparable chronic graft-versus-host disease (cGVHD) in host bm12 mice as the T cells from WT mice. B cells from WDFY1-KO mice also remain capable of being fully activated and differentiated in response to independent Ag challenges. Immunofluorescence staining reveals reduced binding of ICs with FDCs in WDFY1-KO mice compared to WT control mice. Mixed leukocyte reaction results show no intrinsic defect in B cells. B-cell reconstitution in Rag1-KO mice also revealed that WDFY1 is critical for FDCs. Collectively, our studies indicate that WDFY1 knockout impairs the normal functioning of FDCs, resulting in reduced autoAb response to cGVHD.","PeriodicalId":16045,"journal":{"name":"Journal of immunology","volume":" ","pages":""},"PeriodicalIF":3.6,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143764024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
