Uptake of3H-GABA (γ-aminobutyric acid) and3H-leucine in the pancreatic islets and substantia nigra of the rat

Isolated pancreatic islets and thin slices of substantia nigra (SN) of the rat were incubated in a medium containing3H-GABA or3H-leucine to test the activity of both tissues in the uptake of those substances. Pancreatic islets showed a low uptake of both3H-GABA and3H-leucine, but SN had a high activity in the uptake of3H-GABA, though not for3H-leucine. This suggests that GABA contained at high levels in the pancreatic islets plays some functional role other than in neurotransmission as in the central nervous system (CNS).
