ENTPD1 and neoplasm: To further evaluate whether CD103+CD39+ T cells represented the immune signature of the high IRScore group, we calculated IRScore of tumor-infiltrating CD4+/CD8+ T cells from a single-cell dataset (GSE108989) and investigated gene expression patterns of CD4+/CD8+ TILs co-expressing CD103 (ITGAE) and CD39 (ENTPD1).
