Figure S1. CD28 is not required for TCR-mediated rapid glycolysis in naïve nor previously activated CD8+ T cells. (Supports Figure 2) A, (Left) ECAR trace of naïve, CD8+ T cells stimulated with streptavidin or streptavidin crosslinked- αCD3 at 3 μg/ml in the presence or absence of 2 μg/ml αCD28, (right) tabulated results from multiple experiments. B, (Right) tabulated ECAR of naïve, CD8+ T cells stimulated with indicated amounts of streptavidin-crosslinked αCD3 in the presence or absence of αCD28, (left, top) trace ECAR of optimal TCR activation, (left, bottom) trace ECAR of suboptimal activation. Results represent the mean of five (A) or three (B) independent experiments. ** p < 0.01 ns, not significant by unpaired t-test. Error bars represent SEM.

Figure S2. TCR signaling does not induce phosphorylation of glycolytic enzymes but rather reroutes glucose processing. (Supports Figure 3) A, (Left) representative immunoblot (IB) of indicated phospho or total proteins in lysates from previously activated, CD8+ T cells stimulated for the indicated periods with streptavidin-crosslinked αCD3 at 3 μg/ml, (right) tabulated densitometry scanning. B, IB of immunoprecipitations of phospho-tyrosine in lysates from PA-R CD8+ T cells stimulated as in A. C IB of immunoprecipitation of phospho-tyrosine in lysates from PA-R CD8+ T cells stimulated as in A. D, (Top) representative IB of indicated phospho or total proteins in lysates from PA-R CD8+ T cells stimulated as in A for the indicated periods in the presence or absence of 20 mM DCA, (bottom) tabulated densitometry scanning. E, Flow chart for 13C-glucose experiment. Freshly isolated CD8+ T cells were rested 30 min in Seahorse media containing glucose, stimulated with 3 ug/mL anti-CD3 for 30 minutes, and then pulsed with an equimolar concentration (10 mM) of 13C-uniformly labeled glucose. Metabolites were extracted 1 h after pulse. F, 13C labeled pyruvate from experiment described in E. G, 13C labeled lactate from experiment described in E. H, 13C labeled malate from experiment described in E. I, 13C labeled citrate from experiment described in E. J, Unlabeled (m+0) malate and citrate levels from E. Results represent three independent experiments. NS, not significant by unpaired t-test.
