While the rate of glycolysis was found to be reduced in ME/CFS CD4+ and CD8+ T cells [7], we found no difference in glycolytic rate in ME/CFS lymphoblasts [2], nor did Tomas et al. in ME/CFS PBMCs or skeletal muscle cells [8,9]. This evidence concerns the gene CD8A and myalgic encephalomeyelitis/chronic fatigue syndrome.
