Accurate and holistic evaluation of the ILC landscape is critical to understanding the contribution of ILCs to disease pathology. Using high-parameter flow cytometry, we comprehensively interrogated the phenotypic and functional diversity of ILCs in healthy volunteers and patients with severe asthma (SA), assessing the reciprocity between peripheral blood and airway compartments and dissecting the impact of anti–IL-5/5Rα biologics on these responses. We identified substantial heterogeneity and putative plasticity in human ILC responses, highlighting inherent limitations of conventional enumeration strategies.

Here, we show that lower VLC-PUFA abundance in the aged mouse retina is accompanied by a reduction in visual function. Similarly, mice lacking ELOVL2-specific enzymatic activity (<i>Elovl2<sup>C234W</sup></i>) demonstrate reduced contrast sensitivity and slower rod-mediated dark adaptation. Intravitreal supplementation with the direct product of ELOVL2, 24:5n-3, in aged animals improved visual function for up to 4 weeks and reduced accumulation of APOE- and C3d-positive sub-RPE deposits.

Elevated anti-DENV afucosylation, present before or after vaccination, was associated with increased likelihood of infection after vaccination.

Conversely, PDAC with VI demonstrated down-regulation of genes associated with mesenchymal differentiation, basal-like subtype, and disease aggression. Additionally, we uncovered characteristics of VI morphology that correlated with these molecular features.

We contextualized our findings using public RNA-seq data and observed that metastatic PDAC had greater similarity to PDAC in stroma than to PDAC with VI, whereas circulating tumor cells showed no preferential association. We confirmed our findings by spatial proteomic analysis of VI in an independent cohort of 19 treatment-naïve patients with PDAC.

Preemptive intervention in at-risk individuals could prevent or delay future tissue damage; however, the immunobiology of this stage is unclear. Using integrative multiomics, we longitudinally profiled at-risk individuals, where one-third of participants developed clinical RA on study. We found evidence of systemic inflammation and signatures of activation in naïve T and B cells of at-risk individuals. During progression to clinical RA, proinflammatory skewing of atypical B cells and expansion of memory CD4 T cells with signatures of activation and B cell help were present without elevations in circulating ACPA titers. Epigenetic changes in naïve CD4 T cells suggested a predisposition to differentiate into effector cells capable of B cell help. These findings characterize pathogenesis of the ACPA<sup>+</sup> at-risk stage and support the concept that the disease begins much earlier than clinical RA. Additionally, an extensive immune resource of the at-risk stage and progression to clinical RA with interactive tools was developed to enable further investigation.</div>","PeriodicalId":21580,"journal":{"name":"Science Translational Medicine","volume":"17 817","pages":""},"PeriodicalIF":14.6,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.science.org/doi/reader/10.1126/scitranslmed.adt7214","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145129539","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}
