Krüppel-like factor 4 regulates the cytolytic effector function of exhausted CD8 T-cells [ATAC-Seq]

Project description:Since exhausted CD8 T-cells are known to have a strong epigenetic imprint, which is a major obstacle for reinvigoration, we investigated whether the induced Klf4 expression could change the epigenetic status of the exhausted CD8 T-cells. For this, we performed ATAC-sequencing and compared chromatin landscapes between naïve, in vitro generated effector, exhausted (GFP-induced), and reinvigorated (KLF4-induced) CD8 T-cells.

Transcription profiling of mouse naive, effector, memory and exhausted virus-specific CD8 T cells after chronic viral infection

Project description:CD8 T cells normally differentiate from resting naÃ¯ve T cells into function effector and then memory CD8 T cells following acute infections. During chronic viral infections, however, virus-specific CD8 T cells often become exhausted. We used microarrays to examine the gene expression differences between naive, effector, memory and exhausted virus-specific CD8 T cells following lymphocytic choriomeningitis virus infection. Experiment Overall Design: Three or four independent samples were sorted by flow cytometry for each cell type (naive, effector, memory and exhausted) virus-specific CD8 T cells. RNA was extracted and hybridized to Affymetrix microarrays.

Krüppel-like factor 4 regulates the cytolytic effector function of exhausted CD8 T-cells [RNA-Seq]

Project description:To identify the role of KLF4 on exhausted CD8 T-cells, we retrovirally transduced Klf4 into OT-I CD8 T-cells on day1 of in vitro exhaustion model and repeatedly treated OVA peptide to induce exhaustion. Then we analyzed the gene expression profiles of these transduced cells by RNA-sequencing.

Krüppel-like factor 4 regulates the cytolytic effector function of exhausted CD8 T-cells [SMART-Seq]

Project description:To identify the role of KLF4 on exhausted CD8 T-cells in vivo, we adoptively transferred PmelI CD8 T-cells transduced with MigRI/Klf4 into MC38-gp100 tumor-bearing Rag2 KO mice on day7. We then isolated tumor-infiltrating PmelI CD8 T-cells on day15 and their gene expression profiles were analyzed by SMART-seq. Also, to investigate the effect of KLF4 deficiency, we isolated PD1+ CD8+ TILs from MC38 tumor-bearing control and Klf4 cKO mice on day14, and SMART-seq was performed.

Gene expression profiles of human effector CD8+ T cell subsets

Project description:Effector CD8+ T cells are believed to be terminally differentiated cells having cytotoxic activity and the ability to produce effector cytokines such as INF-M-NM-3 and TNF-M-NM-1. We investigated the difference between CXCR1+ and CXCR1- subsets of human effector CD27-CD28-CD8+ T cells. Both subsets similarly expressed cytolytic molecules and exerted substantial cytolytic activity, whereas only the CXCR1- subset had IL-2 productivity and self-proliferative activity and was more resistant to cell death than the CXCR1+ subset. These differences were explained by the specific up-regulation of CAMK4, SPRY2, and IL-7R in the CXCR1- subset and that of pro-apoptotic DAPK1 in the CXCR1+ subset. The IL-2 producers were more frequently found in the IL-7R+ subset of the CXCR1- effector CD8+ T cells than in the IL-7R- subset. IL-7/IL-7R signaling promoted cell survival only in the CXCR1- subset. The present study has highlighted a novel subset of effector CD8+ T cells producing IL-2 and suggests the importance of this subset in the homeostasis of effector CD8+ T cells. To find the genes that potentially cause the difference in IL-2 productivity and cell survival between the CXCR1+ and CXCR1- human effector CD8+ T cell subsets, we performed microarray gene expression analysis. We highly purified each CD3+CD8+ subset for this analysis (> 95.3%) from 5 healthy individuals, and then compared the gene expression profiles of each subset.
