LID assessment of D5 KO mice. Mice were treated with L-DOPA/Benserazide (L-DOPA 3 mg/kg, Benserazide 10 mg/kg, i.p.) daily and AIMs determined starting at 20 min post injection. Total AIMs scores (A,D,G) ALO score (A,E), LOC score (B,F) and were determined and plotted as summarized score or as time course at 20 min intervals for 2 hours after L-DOPA injection (N = 10–12). SKF83959 (0.2 mg/kg, i.p.) was injected instead of L-DOPA and total AIMs, ALO and ROT scores assessed (G–I), (N = 6). Graphs show mean values +/− SEM. Statistical analysis was performed using Student’s t-test (A (p > 0.05), D, G (p < 0.05)) and 2-way ANOVA (Effect of genotype (B): F(1, 120) = 10.6, p = 0.0015; (C): F(1, 120) = 3.45, p > 0.05; (E): F(1, 120) = 41.5, p < 0.0001; (F): F(1, 120) = 15.26, p = 0.0002; (H): F(1, 120) = 23.58, p < 0.0001; (I): F(1, 120) = 13.4, p = 0.0004). Sidak’s multiple comparisons post-test (**P < 0.01;*P < 0.05).
