... of proteinsinvolved in retinoid-related metabolism (retinoic acidreceptors, cellular binding proteins and oxidizing enzymes)have been mapped within the adult dopamine system [35]. In the adult ... dataindicate that adult brain tissue, in particularly the striatum,can oxidize retinol to retinal, providing the first step on the way to retinoic acid [31]. The brain must thus rely on the activity ... expression ofADH3 in most of the analyzed areas in the brain, withhighest expression levels in hippocampus, cerebellum andparticularly in human brain, in the red nucleus.
