Abstract

T cell lineages are defined by specialized functions and differential expression of surface antigens, cytokines and transcription factors. Conventional CD4+ and CD8+ T cells are the best studied of the T cell subsets, but 'unconventional' T cells have emerged as being more abundant and influential than has previously been appreciated. Key subsets of unconventional T cells include natural killer T (NKT) cells, mucosal-associated invariant T (MAIT) cells and γδ T cells; collectively, these make up ~10% of circulating T cells, and often they are the majority of T cells in tissues such as the liver and gut mucosa. Defects and deficiencies in unconventional T cells are associated with autoimmunit..
