Abstract
A wide variety of suppressive pathways have been investigated in efforts to understand the basis for immune tolerance. Although the contribution of CD4+ regulatory T cells (Tregs) to self-tolerance has been extensively studied, less attention has been given to CD8+ Tregs. Here we review recent insights into the development, function, and potential clinical applications of this regulatory subset. We focus on CD8+ Tregs that recognize self-peptides associated with MHC-Ib products and that express Ly49/KIR (killer cell immunoglobulin-like receptor) coinhibitory receptors. Recent analyses of their T cell receptor repertoire, thymic differentiation, and mechanism of suppression are summarized. Identification of the human homolog of these cells has suggested new strategies for CD8+ Treg-dependent immunotherapy for autoimmune disease and cancers.
期刊介绍：
The Annual Review of Immunology, in publication since 1983, focuses on basic immune mechanisms and molecular basis of immune diseases in humans. Topics include innate and adaptive immunity; immune cell development and differentiation; immune control of pathogens (viruses, bacteria, parasites) and cancer; and human immunodeficiency and autoimmune diseases. The current volume of this journal has been converted from gated to open access through Annual Reviews' Subscribe to Open program, with all articles published under a CC BY license.
