WitrynaWe recently characterised the NUP98-HOXD13 (NHD13) mouse as a model of T-cell pre-leukaemia, featuring thymocytes that can engraft in recipient animals and progress to T-cell acute lymphoblastic leukaemia (T-ALL). However, loss of this engraftment ability by deletion of Lyl1 did not result in any loss of leukemogenesis activity. In the present … Witryna23 lis 2024 · To investigate microbiome influences on T cells at an earlier, immature stage, we compared single-cell TCR transcript sequences between CD4+CD8+ (double-positive) thymocytes from gnotobiotic [ E. coli mono-associated (Ec)] and …
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.
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.

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.
