title: Anatomical mapping of glucose transporter protein and pyruvate dehydrogenase in rat brain: an immunogold study.
abstract: The regional and cellular distributions of glucose transporter protein (GT) and pyruvate dehydrogenase (PDH) have been studied with an enhanced immunogold method. The results showed significant amounts of GT in neuropil within regions known to exhibit high demands for glucose whilst neuronal perikarya showed little immunostaining. In contrast PDH immunostaining was most intense in neuronal perikarya. The distributions of these proteins were compared and discussed in relation to existing data on local cerebral glucose utilization and the distribution of other important metabolic enzymes. The results suggest that glucose is transported and metabolised in neuropil and that metabolic products such as pyruvate are transported into the neuronal cell body to undergo further metabolism.
