In patients with rheumatoid arthritis (RA), CD4(+)T cells hyperproliferate during clonal expansion, differentiating into cytokine-producing effector cells that contribute to disease pathology. However, the metabolic underpinnings of this hyperproliferation remain unclear. In contrast to healthy T cells, naïve RA T cells had a defect in glycolytic flux due to the up-regulation of glucose-6-phosphate dehydrogenase (G6PD). Excess G6PD shunted glucose into the pentose phosphate pathway, resulting in ...[more]
