BCL-XL levels were also higher, though to a lesser extent, in conventional TI-CD4+ Tconv versus their PB-counterparts (Fig. 1d, f); whereas TI-CD8+ T cells exhibited increased BCL-XL in BrCa (Fig. 1d) but decreased level in ccRCC relative to PB CD8+ T cells (Fig. 1f). This evidence concerns the gene CD4 and nonpapillary renal cell carcinoma.
