Effects of FIV infection on feline astrocyte glutamate uptake. At the indicated time points, after infection with either (a) FIV-34TF10 or (b) FIV-PPR virus, the [3H]glutamate uptake assay was performed, as described in Materials and Methods. Results are expressed as the ratio of [3H]glutamate 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.
