Figure 6. gp120-treated rats exhibit apoptosis and neuronal loss.
Rats were treated as described in Figure 5. The number of caspase-3 positive RGC (A) and FR labeled cells (B) was counted using MetaMorph®. By 3 and 18 days, at least 25 ± 6 and 18 ± 3 cells per field, respectively, were caspase-3 positive. Data expressed as % above control are the mean ± SEM of 4 animals each group. #p<0.05, *<p0.005 vs control.
