Abstract
Aging is a significant risk factor for autoimmunity, and many autoimmune diseases tend to onset during adulthood. We conducted an extensive analysis of CD4+ T cell subsets from 354 patients with autoimmune disease and healthy controls via flow cytometry and bulk RNA sequencing. As a result, we identified a distinct CXCR3midCD4+ effector memory T cell subset that expands with age, which we designated “age-associated T helper (THA) cells.” THA cells exhibited both a cytotoxic phenotype and B cell helper functions, and these features were regulated by the transcription factor ZEB2. Consistent with the highly skewed T cell receptor usage of THA cells, gene expression in THA cells from patients with systemic lupus erythematosus reflected disease activity and was affected by treatment with a calcineurin inhibitor. Moreover, analysis of single-cell RNA sequencing data revealed that THA cells infiltrate damaged organs in patients with autoimmune diseases. Together, our characterization of THA cells may facilitate improved understanding of the relationship between aging and autoimmune diseases.
期刊介绍:
Science Immunology is a peer-reviewed journal that publishes original research articles in the field of immunology. The journal encourages the submission of research findings from all areas of immunology, including studies on innate and adaptive immunity, immune cell development and differentiation, immunogenomics, systems immunology, structural immunology, antigen presentation, immunometabolism, and mucosal immunology. Additionally, the journal covers research on immune contributions to health and disease, such as host defense, inflammation, cancer immunology, autoimmunity, allergy, transplantation, and immunodeficiency. Science Immunology maintains the same high-quality standard as other journals in the Science family and aims to facilitate understanding of the immune system by showcasing innovative advances in immunology research from all organisms and model systems, including humans.
