abstractText | The acquisition of cytotoxic effector function by CD8(+) T cells is crucial for the control of intracellular infection and tumor invasion. However, it remains unclear which signaling pathways are required for the differentiation of CD8(+) cytotoxic T lymphocytes. We show here that Notch2-deficient T cells had impaired differentiation into cytotoxic T lymphocytes. In addition, dendritic cells with lower expression of the Notch ligand Delta-like 1 induced the differentiation of cytotoxic T lymphocytes less efficiently. We found that the intracellular domain of Notch2 interacted with a phosphorylated form of the transcription factor CREB1, and together these proteins bound the transcriptional coactivator p300 to form a complex on the promoter of the gene encoding granzyme B. Our results suggest that the highly regulated, dynamic control of T cell cytotoxicity depends on the integration of Notch2 and CREB1 signals. |
