CD4 and Chronic colitis: To test whether CD4+ and CD8+ T cells are metabolically affected in their ability to consume glucose to perform aerobic glycolysis during acute and chronic colitis, we measured their uptake of 2-(7-Nitro-2, 1, 3-benzoxadiazol-4-yl)-D-glucosamine (2-NBDG), a traceable fluorescent derivative of glucose.
