Abstract

Type 1 diabetes (T1D) is a chronic autoimmune disease characterized by the loss of insulin-producing cells in the pancreatic islets. Patients with T1D have autoreactive CD4⁺ and CD8⁺ T cells that show specific features, indicating previous exposure to self-antigens. Despite that memory T cells are vital components of the adaptive immune system, providing enduring protection against pathogens; individuals with T1D have a higher proportion of memory T cells compared to healthy individuals with naїve phenotypes. Targeting memory T cells in newly diagnosed T1D patients has shown promising results, providing evidence for the significant role of memory T cells in this disease. There are various types of memory T cells, each with unique characteristics and functions. Recent advancements in understanding the complexity and heterogeneity of T cell subpopulations have shown that T1D cannot be fully understood through simple categorization. This review aims to discuss various types of memory T cells in the immunopathogenesis of T1D, focusing on their phenotypes and frequencies, as well as epigenetic and metabolic alterations. Additionally, it will address novel immunotherapeutic approaches targeting memory T cell subsets in T1D.

期刊介绍： Autoimmunity Reviews is a publication that features up-to-date, structured reviews on various topics in the field of autoimmunity. These reviews are written by renowned experts and include demonstrative illustrations and tables. Each article will have a clear "take-home" message for readers. The selection of articles is primarily done by the Editors-in-Chief, based on recommendations from the international Editorial Board. The topics covered in the articles span all areas of autoimmunology, aiming to bridge the gap between basic and clinical sciences. In terms of content, the contributions in basic sciences delve into the pathophysiology and mechanisms of autoimmune disorders, as well as genomics and proteomics. On the other hand, clinical contributions focus on diseases related to autoimmunity, novel therapies, and clinical associations. Autoimmunity Reviews is internationally recognized, and its articles are indexed and abstracted in prestigious databases such as PubMed/Medline, Science Citation Index Expanded, Biosciences Information Services, and Chemical Abstracts.
