Identification of an Acceptor System for γ‐Aminobutyric Acid on Isolated Rat Hepatocytes
Gerald Y. Minuk, John Vergalla, Peter Ferenci, E. Anthony Jones – 1 March 1984 – γ‐Aminobutyric acid (GABA) is a potent inhibitory neurotransmitter which is synthesized by the enteric bacterial flora and delivered into portal venous blood. To determine whether the liver is likely to play an important role in regulating serum GABA levels, the uptake and metabolism of [3H]GABA by three populations of cells isolated from rat liver were studied. GABA was specifically taken up by hepatocytes but not by endothelial or Kupffer cells.
