scRNA-seq of tumor-specific CD8+ T cells
Tumor-specific CD8+ T cells are heterogeneous; Tcf1+ stem-like CD8+ T cells give rise to cytotoxic Tim-3+ terminally differentiated CD8+ T cells. The goal of this study is to determine the capacity of CD69 to regulate differentiation of tumor-specific CD8+ T cells in the tumor microenvironment and tumor-draining lymph nodes. Our single-cell RNA-seq and RNA-seq analyses of tumor-specific CD8+ T cells reveal the important function of CD69 in anti-tumor CD8+ T cell immunity. Thus, CD69 is an attractive target for cancer immunotherapy. Overall design: AH1 tetramer+ CD8+ T cells were sorted and subjected to scRNA-seq.
