Immature cd8 single-positive thymocytes

WitrynaCD4 + CD8 − and CD4 − CD8 + (single positive) thymocytes, both of which express high surface density of αβ TCR ( 1 – 4 ), ( Fig. 1 ). Immature double-positive thymocytes are the predominant T lymphocyte subset in the thymus, accounting for approx 85% of T cells within the thymus ( 1, 2 ). 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.

Witryna10 sty 2024 · On-line Summary: Immature CD8 single-positive (ISP) thymocytes are identified as a molecularly-distinct thymocyte subpopulation, dependent on BRD4 for progression to the DP stage. DN and DP are BRD4-independent. These findings provide new insights into BRD4, a therapeutic target in inflammation and cancer.
