Chronic CBD treatment reduced CD68 expression in Cln1−/− S1BF (p < 0.0001 for ANOVA; p = 0.0007 for pairwise comparison between treated and untreated Cln1−/− mice) as well as GFAP expression in VPM/VPL of the thalamus (p < 0.0001 for ANOVA, p = 0.0130) (Fig. 1a–h). The gene discussed is GFAP; the disease is red-green color blindness.
