WebJan 12, 2024 · CD8 + CD25 high CD127 low/neg were also largely EGFP +, whereas CD8 + CD25 − CD127 + cells were largely EGFP − (Fig. 3A). Using CD45RC, a marker that has been used both for CD4 + and CD8 + Treg in rats and humans [ 13 , 15 , 16 ], EGFP + cells were detected mostly among CD45RC − CD4 + and CD8 + T cells but also in a lesser … WebJan 1, 2005 · To assess the activation status of the proliferated T cells we measured the expression of the IL2 receptor (CD25). The proliferated T cells in the untreated MLC expressed high levels of CD25 but the CD25 expression was reduced on both CD4 + and CD8 + T cells in anti-CD3 mAb treated MLC (Fig. 4).In addition, the viability and the level …
