Notch1 regulates maturation of CD4+ and CD8+ thymocytes by modulating TCR signal strength.


Notch signaling regulates cell fate decisions in multiple lineages. We demonstrate in this report that retroviral expression of activated Notch1 in mouse thymocytes abrogates differentiation of immature CD4+CD8+ thymocytes into both CD4 and CD8 mature single-positive T cells. The ability of Notch1 to inhibit T cell development was observed in vitro and in… (More)
