The S enantiomer of 2-hydroxyglutarate increases central memory CD8 populations and improves CAR-T therapy outcome

Study aim: Investigate the effect of S-2HG (2-hydroxyglutarate) metabolite on the mRNA levels of human CD8 T cells Methods: Naïve CD8 T cells were isolated from human healthy donors. The CD8 T cells were aCD3/CD28 beads (1:1 bead-to-cell ratio) and IL-2 (30 U/ml) for 4 days. The cells were treated with S-2HG (0.4 mM) or vehicle (H2O) from the day of isolation and for 12 days before collection. Library preparation and paired-end RNA sequencing using Illumina NextSeq 500, as well as downstream data analysis, were performed by Active Motif. Overall design: human CD8 mRNA profiles of 3 independent healthy donors treated with S-2HG (0.4 mM) or vehicle (H2O) for 12 days
