Abstract

After two decades of the study of lipid antigens that activate CD1-restricted T cells, new studies show how autoreactive αβ T-cell receptors (TCRs) can directly recognize the outer surface of CD1 proteins in ways that are lipid-agnostic. Most recently, this lipid agnosticism has turned to negativity, with the discovery of natural CD1 ligands that dominantly negatively block autoreactive αβ TCR binding to CD1a and CD1d. This review highlights the basic differences between positive and negative regulation of cellular systems. We outline strategies to discover lipid inhibitors of CD1-reactive T cells, whose roles in vivo are becoming clear, especially in CD1-mediated skin disease.

CD1显示出自己的负调节因子。

经过20年对激活CD1限制性T细胞的脂质抗原的研究，新的研究表明，自身反应性αβT细胞受体（TCRs）如何以脂质不可知的方式直接识别CD1蛋白的外表面。最近，随着天然CD1配体的发现，这种脂质不可知论已转向消极，该配体主要负性阻断自身反应性αβTCR与CD1a和CD1d的结合。这篇综述强调了细胞系统正调控和负调控之间的基本区别。我们概述了发现CD1反应性T细胞脂质抑制剂的策略，其在体内的作用越来越清楚，尤其是在CD1介导的皮肤病中。

期刊介绍： Current Opinion in Immunology aims to stimulate scientifically grounded, interdisciplinary, multi-scale debate and exchange of ideas. It contains polished, concise and timely reviews and opinions, with particular emphasis on those articles published in the past two years. In addition to describing recent trends, the authors are encouraged to give their subjective opinion of the topics discussed. In Current Opinion in Immunology we help the reader by providing in a systematic manner: 1. The views of experts on current advances in their field in a clear and readable form. 2. Evaluations of the most interesting papers, annotated by experts, from the great wealth of original publications. Current Opinion in Immunology will serve as an invaluable source of information for researchers, lecturers, teachers, professionals, policy makers and students. Current Opinion in Immunology builds on Elsevier''s reputation for excellence in scientific publishing and long-standing commitment to communicating reproducible biomedical research targeted at improving human health. It is a companion to the new Gold Open Access journal Current Research in Immunology and is part of the Current Opinion and Research(CO+RE) suite of journals. All CO+RE journals leverage the Current Opinion legacy-of editorial excellence, high-impact, and global reach-to ensure they are a widely read resource that is integral to scientists'' workflow.
