We examine the ability of several putative amino acid neurotransmitters to influence immunoreactive somatostatin (IRS) release from cultured rat cerebral cortical cells. The cells were exposed to either single or sequential incubations in various concentrations of glutamate (Glu), aspartate (Asp), GABA, glycine, taurine and arginine. Glu and Asp were stimulatory to IRS release, whereas GABA was inhibitory. Glu-induced IRS release was calcium-dependent. Glycine and taurine were weak stimulants.
