Using mouse models of airborne exposure to house dust mites and Alternaria, we found that allergen sensitization generated lymph node (LN)- and lung-resident MBCs. Upon allergen re-exposure, MBCs follow two differentiation trajectories: a germinal center (GC)-dependent pathway, generating IgG1+ and IgE+ plasma cells (PCs) and occurring predominantly in LNs, and a GC-independent pathway, generating mainly IgG1+ PCs and present in both organs. GC re-entry granted MBCs access to an interleukin (IL)-4-rich microniche formed by T follicular helper (Tfh) cells, which was essential for IgE production. Disrupting GC re-entry, IL-4 signaling, or Tfh cell-derived IL-4 during recall markedly reduced allergen-specific IgE. These findings reveal a spatially and cytokine-restricted mechanism that confines IgE memory to lymphoid organs, positioning GC IL-4 microniches as anatomical safeguards against IgE production at barrier sites frequently exposed to environmental antigens.","PeriodicalId":13269,"journal":{"name":"Immunity","volume":"26 1","pages":""},"PeriodicalIF":32.4,"publicationDate":"2026-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149019708","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}

However, allergens are typically encountered through repeated subthreshold exposures, and how these cumulatively induce sensitization is unknown. We identified a sensory neuron-intrinsic mechanism of neuroimmune memory. Protease allergen exposure induced sustained mechanistic target of rapamycin complex 1 (mTORC1) kinase signaling and transcriptional activator peroxisome proliferator-activated receptor gamma coactivator-1α (PGC-1α)-associated mitochondrial remodeling in sensory neurons, establishing a metabolically primed state with enhanced neuronal responsiveness. Upon allergen re-exposure, this state drove enhanced itch, CD301b+ dendritic cell migration, and Th2 cell differentiation. Disrupting neuronal mTORC1 signaling or mitochondrial stability abrogated this amplification while sparing primary responses. This mechanism generalized across distinct protease allergens, revealing mTORC1-driven metabolic reprogramming in sensory neurons as a form of innate neuroimmune memory underlying allergen cross-sensitization and polysensitization.","PeriodicalId":13269,"journal":{"name":"Immunity","volume":"47 1","pages":""},"PeriodicalIF":32.4,"publicationDate":"2026-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149013592","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}

Here, we examined the immunogenicity and antigenicity of p53 neoantigens emerging from these truncal mutations. Comprehensive immunopeptidomics revealed that hotspot mutations in human tumors preferentially localize to p53 regions resistant to antigen processing, thereby avoiding display altogether. Moreover, for neoantigens presentable by HLA-A∗02:01 or HLA-B∗07:02 and structurally divergent from corresponding wild-type p53 peptide-HLA complexes, clinical tumors commonly lacked the relevant presenting HLA allele. Tumor cells further resisted T cell killing through increased activity of the aminopeptidase ERAP1, preventing display of high-affinity HLA-A∗02:01 complexes containing an immunogenic p53I195F-derived 11-mer, or by expressing low-affinity HLA-A∗02:01 complexes containing a p53R175H-derived 9-mer with poor antigenicity despite high-quality human TCRs.
