The ADHD model (SHR Veh) presented a decrease in VGlut1 immunostaining in the OPL (9.8 × 104 ± 6.43 × 103 vs. 7.7 × 104 ± 5.3 × 103 arbitrary units) and IPL (3.0 × 104 ± 2.3 × 103 vs. 2.5 × 104 ± 2.5 × 104 arbitrary units) as compared to WKY Veh (Figure 4B,C). Here, SLC17A7 is linked to attention deficit-hyperactivity disorder.
