摘要:

Using Chromium 10X technology, we performed single-cell RNA sequencing (scRNA-seq) of 6,311 T cells isolated from human BCs. We demonstrate that BCs with a high number of Tumor Inflitrating Lymphocytes (TILs) contained CD8 T cells with features of tissue-resident memory T (TRM) cell differentiation and that these CD8 TRM  cells expressed high levels of immune checkpoint molecules and effector proteins. A CD8 TRM gene signature developed from the scRNA-seq data was significantly associated with improved patient survival in early-stage triple-negative breast cancer (TNBC) and provided better prognostication than CD8 expression alone.
