Regulatory T cells can inhibit harmful immunopathological responses directed against self and foreign antigens and play a major role in controlling autoimmunity. Here we have identified and characterized a subpopulation of CD4 and CD8 T cells in human peripheral blood expressing the immune tolerizing molecule HLA-G. HLA-G-expressing T cells are hypoproliferative, CD25- and FOXP3-negative, and exhibit potent suppressive properties which are partially mediated by HLA-G. HLA-G positive (HLA-Gpos) T cells are found at low percentages among CD4 and CD8 single positive thymocytes, suggesting a thymic origin. The presence of HLA-Gpos T cells at sites of inflammation such as inflamed skeletal muscle in myositis or the cerebrospinal fluid of patients with acute neuroinflammatory disorders suggests an important function in modulating parenchymal inflammatory responses in vivo.
