Immature cd8 single-positive thymocytes
Witryna6 kwi 2024 · The most immature thymocytes lack CD4 and CD8 expression (double-negative, DN). Following the DN stage, cells differentiate into CD4 + CD8 + double-positive (DP) cells, after which they bifurcate to single-positive (SP) CD4 + CD8 − CD3 + or CD8 + CD4 − CD3 + stages that characterize mature T cells. Thymocytes … WitrynaGenes up-regulated in thymocytes: double negative versus double positive. ... Human DN thymocytes mature via an immature single positive (ISP CD4+) and a DP stage into CD4+ or CD8+ SP T cells that express functional T cell receptors (TCR) and that exit the thymus. In this study, gene expression was measured in each of these nine stages.
