Abstract

In autoimmune diseases, recognition of self-antigens presented by major histocompatibility complex (MHC) molecules elicits unexpected attack of tissue by autoantibodies and/or autoreactive T cells. Post-translational modification (PTM) may alter the MHC-binding motif or TCR contact residues in a peptide antigen, transforming the tolerance to self to autoreactivity. Mass spectrometry-based immunopeptidomics provides a valuable mechanism for identifying MHC ligands that contain PTMs and can thus provide valuable insights into pathogenesis and therapeutics of autoimmune diseases. A plethora of PTMs have been implicated in this process, and this review highlights their formation and identification.

用质谱法鉴定自身免疫性疾病中的新抗原:1型糖尿病的例子

在自身免疫性疾病中，对主要组织相容性复合体（MHC）分子呈递的自身抗原的识别会引发自身抗体和/或自身反应性T细胞对组织的意外攻击。翻译后修饰（PTM）可以改变肽抗原中的MHC结合基序或TCR接触残基，将耐受性转化为自我反应性。基于质谱的免疫肽组学为鉴定含有PTMs的MHC配体提供了一种有价值的机制，因此可以为自身免疫性疾病的发病机制和治疗提供有价值的见解。在这一过程中涉及了大量的PTM，本综述强调了它们的形成和鉴定。

期刊介绍： Seminars in Immunology is a specialized review journal that serves as a valuable resource for scientists in the field of immunology. The journal's approach is thematic, with each issue dedicated to a specific topic of significant interest to immunologists. It covers a wide range of research areas, from the molecular and cellular foundations of the immune response to the potential for its manipulation, highlighting recent advancements in these areas. Each thematic issue is curated by a guest editor, who is recognized as an expert in the field internationally. The content of each issue typically includes six to eight authoritative invited reviews, which delve into various aspects of the chosen topic. The goal of these reviews is to provide a comprehensive, coherent, and engaging overview of the subject matter, ensuring that the information is presented in a timely manner to maintain its relevance. The journal's commitment to quality and timeliness is further supported by its inclusion in the Scopus database, which is a leading abstract and citation database of peer-reviewed literature. Being indexed in Scopus helps to ensure that the journal's content is accessible to a broad audience of researchers and professionals in immunology and related fields.
