Interleukin-13 (IL-13)-expressing follicular helper T (TFH13) cells are a newly identified population of TFH cells that have been associated with high-affinity IgE responses. However, the origins, developmental signals, transcriptional programming and precise functions of TFH13 cells are unknown. Here, we examined the developmental signals for TFH13 cells and found a direct and progressive differentiation pathway marked by the production of IL-21. These two pathways differed in kinetics and extrinsic requirements. However, both pathways converged, forming transcriptionally similar TFH13 cells that express the transcription factor JunB as a critical stabilizing factor. Using an intersectional genetics-based TFH13-diphtheria toxin receptor model to perturb these cells, we found that TFH13 cells were essential to drive broad germinal center responses and allergen-specific IgG and IgE. Moreover, we found that IL-21 is a broad positive regulator of allergen germinal center B cells and synergizes with IL-13 produced by TFH13 cells to amplify allergic responses. Thus, TFH13 cells orchestrate multiple features of allergic inflammation. TFH cells that express IL-13 are associated with high-affinity IgE responses, but factors controlling their development, transcriptional programming and exact function have remained unclear. Here, Chandrakar et al. find that the transcription factor JunB is required for TFH13 cell maintenance and that TFH13 cells producing IL-21 drive broad germinal center responses to allergen-specific IgG and IgE.","PeriodicalId":19032,"journal":{"name":"Nature Immunology","volume":"26 3","pages":"473-483"},"PeriodicalIF":27.7,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143071408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We recruited a total of 220 healthy volunteers from the Shanghai Pudong Cohort (NCT05206643), spanning 13 age groups from 0 to over 90 years, and profiled their peripheral immune cells through single-cell RNA-sequencing coupled with single T cell and B cell receptor sequencing, high-throughput mass cytometry, bulk RNA-sequencing and flow cytometry validation experiments. We revealed that T cells were the most strongly affected by age and experienced the most intensive rewiring in cell–cell interactions during specific age. Different T cell subsets displayed different aging patterns in both transcriptomes and immune repertoires; examples included GNLY+CD8+ effector memory T cells, which exhibited the highest clonal expansion among all T cell subsets and displayed distinct functional signatures in children and the elderly; and CD8+ MAIT cells, which reached their peaks of relative abundance, clonal diversity and antibacterial capability in adolescents and then gradually tapered off. Interestingly, we identified and experimentally verified a previously unrecognized ‘cytotoxic’ B cell subset that was enriched in children. Finally, an immune age prediction model was developed based on lifecycle-wide single-cell data that can evaluate the immune status of healthy individuals and identify those with disturbed immune functions. Our work provides both valuable insights and resources for further understanding the aging of the immune system across the whole human lifespan. In this Resource, authors profile peripheral immune cells from a total of 220 healthy volunteers from birth to over 90 years. This revealed that T cells were most affected by aging with divergent aging patterns in different subsets and identified a population of cytotoxic B cells that were enriched in children.","PeriodicalId":19032,"journal":{"name":"Nature Immunology","volume":"26 2","pages":"308-322"},"PeriodicalIF":27.7,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41590-024-02059-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143055072","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Within a very high fraction of differentially expressed genes, we identify a panel of 20 new signature genes in steady-state γδ17 cells versus γδIFN cells, which we further validate in models of experimental autoimmune encephalomyelitis and cerebral malaria, respectively. Among the signature genes, we show that the co-receptor CD6 and the signaling protein Themis promote the activation and proliferation of peripheral γδIFN cells in response to T cell antigen receptor stimulation in vitro and to Plasmodium infection in vivo. This resource can help to understand the distinct activities of effector γδ T cell subsets in pathophysiology.

Here we demonstrate that T cell evasion exists in epitope hotspots spanning BA.2.86/JN.1 mutations. The newly emerging Q229K at this conserved nucleocapsid protein site impairs HLA-A2 epitope hotspot recognition. The association between HLA-A24 convalescents and T cell immune escape points to the spike (S) protein epitope S448–456NYNYLYRLF, with multiple mutations from Delta to JN.1, including L452Q, L452R, F456L, N450D and L452W, and N450D, L452W and L455S. A cliff drop of immune responses was observed for S448–456NYNYRYRLF (Delta/BA.5.2) and S448–456NYDYWYRSF (JN.1), but with immune preservation of S448–456NYDYWYRLF (BA.2.86). Structural analyses showed that hydrophobicity exposure determines the pronounced escape of L452R and L455S mutants, which was further confirmed by T cell receptor binding. This study highlights the characteristics and molecular mechanisms of the T cell immune escape for JN.1 and provides new insights into understanding the dominant circulation of variants, from the viewpoint of cytotoxic T cell evasion.

Here we conducted integrated single-cell profiling of SARS-CoV-2-specific T cells in 122 bronchoalveolar lavage fluid (BALF) and 280 blood samples from 159 patients, including 27 paired BALF and blood samples from 24 patients. SARS-CoV-2-specific T cells were robustly elicited in BALF irrespective of prior vaccination, correlating with diminished viral loads, lessened systemic inflammation and improved respiratory function. SARS-CoV-2-specific T cells in BALF exhibited profound activation, along with proliferative and multi-cytokine-producing capabilities and a glycolysis-driven metabolic signature, which were distinct from those observed in peripheral blood mononuclear cells. After viral clearance, these specific T cells maintained a polyfunctional tissue-resident memory phenotype, highlighting their critical roles in infection control and long-term protection.
