Witryna19 sie 1997 · Dramatic alterations in the thymocyte subpopulations, including an increase in the CD4 + and CD8 + single positive (SP) thymocytes and CD4 − CD8 − double negative (DN) thymocytes, and a decrease in the percentage of CD4 + CD8 + double positive (DP) thymocytes also were reported to occur in CTLA-4 −/− mice ( 7, 8 ).
WitrynaThe pre-TCR checkpoint marks the end of this phase and entry into the double positive (CD4 + CD8 +) phase. After passing through the TCRαβ checkpoint, the developing thymocytes enter the single positive phase and become mature CD4 + CD8 – or CD4 – CD8 + T cells. [Adapted from Yeung, R.S., Ohashi, P., & Mak, T.W. (2007). T … Witryna9 gru 2010 · We identified the immature single-positive (ISP) CD8 + stage of T-cell development as being this transition point. ISP thymocytes were responsive to …
Witryna1 maj 1988 · However, such murine “single positives” include a subpopulation of immature cells with properties resembling CD4 − CD8 − thymocytes or CD4 + CD8 + cortical blasts. Most of these immature single positives are CD4 − CD8 +, some expressing relatively low levels of CD8. They are large, dividing cortisone-sensitive … Witryna1 kwi 1995 · In contrast to CD4+ single-positive cells, most of the CD8+ single-positive cells in the thymoma as well as in the normal thymus expressed CD69 and a high …
