CD8A and melanoma: Re-analysis of public scRNAseq data (GSE120575) from Sade-Feldman et al (Sade-Feldman et al, 2018), where CD45+ leukocytes were sorted from 48 melanoma tumor samples showed that CD70 gene expression is higher in some immune cell populations, such as plasma cell (cluster G2), exhausted CD8+T cells or lymphocytes (G6, G9, G11) and regulatory T cells (G7) (Fig. 2H).
