Abstract:
Endocrine cells of the pyloric antral mucosa are known to take up gamma-amino-n-butyric acid (GABA), but the functional significance of this is uncertain. We now report that specific uptake of [3H]GABA by rat antral, but not corpus, mucosa is enhanced after fasting for 48 h. Decreased extracellular GABA in fasted rats could account for known changes in antral endocrine cell function.
