High impact information on Gabbr1

  • Moreover, the GABAB receptor agonist baclofen, and the antagonist 2-hydroxysaclofen had no effect [9].
  • We propose to designate the classical site as the GABA A and the novel site as the GABA B receptor [10].
  • Direct stimulation of astrocytes, or application of the GABAB-receptor agonist baclofen, potentiated miniature inhibitory postsynaptic currents (mIPSCs) in pyramidal neurons [11].
  • The close correlation of the time courses indicates that fast, G protein-mediated depression of voltage-gated calcium channels and thus direct reduction of the presynaptic calcium influx may contribute to the GABAB receptor-induced inhibition of excitatory synaptic transmission in hippocampal neurons in vitro [12].
  • We examined the effects of the GABAB receptor agonist baclofen and the mu opioid receptor agonist DAGO on postsynaptic currents evoked by minimal stimulation of inhibitory fibers (meIPSCs) in area CA3 [13].

Associations of Gabbr1 with chemical compounds

  • Baclofen, a selective GABAB receptor agonist, reversibly decreased both evoked and spontaneous, miniature, GABAergic inhibitory postsynaptic currents (eIPSCs and mIPSCs, respectively) [22].
  • Inhibition of the cAMP/PKA cascade also affected basal GABA release and, in a subset of neurons, occluded the effects of baclofen, suggesting that the GABAB receptor-mediated inhibitory action on GABA release was mediated via decreases in PKA activity [22].
  • In contrast, the inducible NO synthase inhibitor L-N(6)-(1-iminoethyl)lysine (20 microg), the GABAB receptor agonist baclofen (0.2 microg), the mixed dopamine receptor antagonist cis-flupenthixol (10 microg), and the oxytocin receptor antagonist d(CH2)5Tyr(Me)-Orn8 -vasotocin (1 microg), were ineffective [26].
  • The CB1 antagonists did not affect muscarinic acetylcholine or GABAB receptor signaling [27].
  • LTDi was mediated by activation of a presynaptic GABAB receptor, because it was blocked by saclofen and CGP55845 [(2S)-3-{[(15)-1-(3, 4-dichlorophenyl)ethyl]amino-2-hydroxypropyl)(phenylmethyl)phosphinic acid] [28].
