Project description:The NOTCH1 signaling pathway is a critical determinant of cell fate decisions and drives oncogenesis through mechanisms that are incompletely understood. To elucidate tumorigenic pathways that cooperate with activated Notch1 in leukemogenesis,we performed miRNA expression profiling of normal CD4+CD8+ thymocytes, non-malignant ICN1 over-expressing CD4+CD8+ cells and ICN1-induced tumor CD4+CD8+ cells. Three groups of the murine T cells: Control CD4+CD8+ normal thymocytes vs.non-malignant ICN1-expressing CD4+CD8+ cells vs. ICN1-tumor CD4+CD8+ cells .
Project description:(1) Murine CD4 T cells: naïve vs peptide treated and naïve vs peptide+LPS treated. (2) Murine CD8 T cells naïve vs HY-specific cells from tolerant mice and naïve vs cells from rejecting mice
Project description:We analyzed the TCRb repertoires of CD4 and CD8 single-positive thymocytes isolated from a pediatric donor, as well as CD4 and CD8 single-positive thymocytes matured in vitro from the double-positive stage in 3D organoid co-culture with iPSC-derived thymic epithelial cells (iTECs). Our analysis shows that iTECs are capable of positively selecting thymocytes with diverse TCR repertoires in vitro.
