1 Effect of interleukin-6 and tumor necrosis factor-alpha on GABA release from mediobasal hypothalamus and posterior pituitary. gamma-Aminobutyric Acid interleukin 6 Rattus norvegicus
2 We examined the effect of interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha) on release of gamma-aminobutyric acid (GABA) from mediobasal hypothalamic (MBH) explants and posterior pituitaries (PP) of male rats. gamma-Aminobutyric Acid interleukin 6 Rattus norvegicus
3 IL-6 (10 ng/ml) did not modify basal GABA release from MBH and PP, but significantly increased GABA release under depolarizing conditions (40 mM K(+)). gamma-Aminobutyric Acid interleukin 6 Rattus norvegicus
4 This effect was abolished by incubation of the tissue with indomethacin, an inhibitor of cyclooxygenase activity, indicating that prostaglandins could mediate the stimulation of GABA release induced by IL-6. gamma-Aminobutyric Acid interleukin 6 Rattus norvegicus
5 The current results indicate that IL-6 stimulates GABA release from both hypothalamus and posterior pituitary by a mechanism mediated by prostaglandins. gamma-Aminobutyric Acid interleukin 6 Rattus norvegicus
