Project description:The goal of this study is to determine if central memory (Tcm) and effector memory (Tem) CD8 T cells can be reprogrammed to change their fate. We demonstrate that genetic ablation of Tle3 can promote generation of Tcm cells at the expense of Tem cells, and this can occur during the effector phase of the immune response.

Project description:To compare the transcriptomes between control and Tle1/3/4-deficient HSCs Tle co-repressors can co-opt a number of transcription factors to repress target gene expression. Due to gene duplication during evolution, there are 4 Tle genes in mammalian genome, and their functional redundancy has a major hurdle to understand their roles in hematopoietic stem cells (HSCs). Here we used Vav-Cre to ablate Tle1, 3, and 4 genes in HSCs, and performed RNA-seq to determine the impact of Tle deficiency on HSCs. To further define the regulatory mechanisms, we performed Tle3 ChIPseq on c-Kit+ hematopoietic progenitor cells. The data obtained collectively indicate a critical, intrinsic requirement for Tle corepressors in HSC self-renewal.
