CD3+CD4-CD8- (double negative) T cells: saviours or villains of …
2011年8月15日 · In this commentary we will focus our attention on a somewhat neglected class of T cells called CD3(+)CD4(-)CD8(-) double negative T cells and on their role in inflammation and autoimmunity. We will summarize the most recent views on their origin at the thymic and peripheral levels as well as their tissue localization in immune and non-lymphoid ...
Phenotypic and functional evaluation of CD3+CD4−CD8− T cells …
Human CD8 immunodeficiency is characterized by undetectable CD8 + lymphocytes and an increased population of CD4 − CD8 − (double negative) T lymphocytes. We hypothesized that the double negative subset corresponds to the cellular population that should express CD8 and is committed to the cytotoxic T lymphocyte lineage.
