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.
Project description:Examination of transcriptional changes associated with diet-induced obesity in tumor-infiltrating CD45+ leukocytes from syngeneic MC38 colorectal tumors.
Project description:To characterize the role of Pglyrp1 in tumor immunity, we performed bulk RNA-seq for MC38-OVA tumor infiltrating CD8+ T cells from wild type and Pglyrp1-deficient mice.
Project description:To determine the effect of Egr2 and Egr3 on tumour infiltrating lymphocyte gene expression, GFP-Egr2 knockin (Egr2 Kin) and hCD2-Cre Egr2loxP/loxP Egr3-/- (Egr2/3 DKO) mice were inoculated with MC38 or B16 tumour cells. Fourteen days later, GFP-Egr2high and Egr2-/-Egr3-/- CD8+ tumour infiltrating lymphocytes were isolated from Egr2 Kin and Egr2/3 DKO mice, respectively, and analysed by RNA-seq.
Project description:Evaluation of transcriptional changes associated with advanced age in tumor-infiltrating CD8+ T lymphocytes from within MC38 colorectal tumors.
Project description:To identify unique chromatin regions predicting the anti-tumor efficacy of Nrf2-deleted smart CD8+ T cell therapy, we performed an assay for transposase-accessible chromatin sequencing (ATAC-seq) using tumor-infiltrating CD8+ T cells from tumor-bearing mice transferred Nrf2-deficient CD8+ T cells. From the analysis of ATAC-seq data, we identified quantitatively distinct open regions of chromatin that distinguish Nrf2-deficient CD8+ T cells or WT CD8+ T cells.
Project description:Transcriptional profiling of tumor-infiltrating antigen-presenting myeloid subsets and CD8 T cells in mice bearing MC38-OVA tumors treated with or without radiotherapy, αSIRPα, and/or αPD-1 treatment
Project description:Through forward genetic screening, we found a gene called LDL receptor Related Protein 10 (Lrp10) that plays an important role in the homeostasis and differentiation of peripheral CD8 T cells through its effects on the interleukin 7 receptor (IL7R). Lrp10 knockout mice exhibit enhanced resistance to MC38 tumor growth, and we sought to better define the tumor infiltrating Lrp10+/+ and Lrp10-/- CD8T cells using single cell RNA seq and paired single cell TCR sequencing.
