Effects of FIV infection on astrocyte glucose uptake. At the indicated time points with either FIV-34TF10 (a) or FIV-PPR (b), the ability of the feline astrocyte cultures to remove [3H]2DG from the culture supernatant was determined, as described in Materials and Methods. Results are expressed as the ratio of [3H]glucose uptake of infected cultures over the value of the control cultures, ± SEM. Results were analyzed by ANOVA. ∗, P < 0.05; ∗∗, P < 0.01; ∗∗∗, P < 0.001.
