Upon harvest, CD8 high , CD8 mid and CD8 low CD3 + T cells were sorted and processed for low-input RNA-seq using the Smart-seq2 protocol . f , Heatmap of scaled normalized expression of low-input RNA-seq using the Smart-seq2 protocol of genes in the DNαβ T cell transcriptome score for in vitro induced CD8 high ( n = 3), CD8 mid ( n = 4) and CD8 low T cells at day7 in the absence ( n = 2) or presence ( n = 4) of CXCL16. g Heatmap of regulon activity (RScenic ) of top DNαβ T cell regulons shown in Fig. for sorted CD8 high , CD8 mid and CD8 low T cells from cultured CD8 + T cells harvested at day 7. h Boxplots showing regulon activity for in vitro induced CD8 low T cells at day 7 in the presence or absence of CXCL16 shown in ( g ) for each hierarchical cluster ( n = 3, n = 3 and n = 5 regulons in each cluster, respectively). A paired t-test was used for statistical analysis; n.s.: not significant.
