Abstract
Metabolite-based T-cell immunity is emerging as a major player in antimicrobial immunity, autoimmunity, and cancer. Here, small-molecule metabolites were identified to be captured and presented by the major histocompatibility complex class-I-related molecule (MR1) to T cells, namely mucosal-associated invariant T cells (MAIT) and diverse MR1-restricted T cells. Both MR1 and MAIT are evolutionarily conserved in many mammals, suggesting important roles in host immunity. Rational chemical modifications of these naturally occurring metabolites, termed altered metabolite ligands (AMLs), have advanced our understanding of the molecular correlates of MAIT T cell receptor (TCR)-MR1 recognition. This review provides a generalized framework for metabolite recognition and modulation of MAIT cells.
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.
