Abstract

We have examined the regional brain distribution of [18F]GBR 13119 (18F: beta +, T1/2 = 110 min), a dopamine uptake inhibitor, in CD-1 and C57BL/6 mice. High levels of binding are observed in the striatum of both species, with striatum/cerebellum ratios of 3-4 at 60 min after injection of the radiotracer. Striatum radioactivity and striatum/cerebellum ratios are more than 50% reduced in C57BL/6 mice treated chronically with the neurotoxin MPTP. We conclude mice are an appropriate model for the in vivo study of the dopamine uptake system, and that [18F]GBR 13119 may be a suitable in vivo marker for degeneration of striatal dopaminergic neurons.
