We hypothesized that the chronic dietary deficiency of n-3 polyunsaturated fatty acids (n-3 PUFAs) might affect the density and/or function of dopamine transporters (DAT), which have a major role in regulating the synaptic level of dopamine. This hypothesis was tested by investigating DAT in the striatum using three complementary methods in control and deficient rats. The density of DAT was determined by quantitative autoradiography using [(125)I]PE2I, a specific ligand of this transporter. Functional investigations were performed (i) in vitro by measuring [(3)H]dopamine uptake on synaptosomes, and (ii) in vivo using intracerebral microdialysis. The results demonstrated that neither the density nor the function of DAT were influenced by n-3 PUFA deficiency in the striatum. This suggests lower sensitivity to n-3 PUFA deficiency in the striatum than that previously observed in the frontal cortex.
