Dataset Information

CD28 and CD57 define four populations with distinct phenotypic properties within human CD8+ T cells.


ABSTRACT: After repeated antigen exposure, both memory and terminally differentiated cells can be generated within CD8+ T cells. Although, during their differentiation, activated CD8+ T cells may first lose CD28, and CD28- cells may eventually express CD57 as a subsequent step, a population of CD28+ CD57+ (DP) CD8+ T cells can be identified in the peripheral blood. How this population is distinct from CD28- CD57- (DN) CD8+ T cells, and from the better characterized non-activated/early-activated CD28+ CD57- and senescent-like CD28- CD57+ CD8+ T cell subsets is currently unknown. Here, RNA expression of the four CD8+ T cell subsets isolate
