WebMar 21, 2012 · To determine whether the release of GABA and glutamate from POMC terminals can be readily modulated, opioid and GABA B receptor agonists were applied. Agonists for μ- and κ-, but not δ-opioid receptors inhibited transmitter release from POMC neurons, as did the GABA B receptor agonist baclofen. This regulation indicates that … WebThese results support the hypothesis that GABA (A) and opioid receptors within the CeA can selectively regulate EtOH-maintained responding. The CeA may represent a novel target site in the development of prototypical GABA (A) and opioidergic receptor ligands, which selectively reduce alcohol abuse in humans.

WebOpioids and endogenous opioids activate presyn-aptic receptors on GABA neurons, which inhibit the release of GABA in the ventral tegmental area (Fig. 5). The inhibition of GABA allows dopaminergic neu-rons to fire more vigorously, and the extra dopamine in the nucleus accumbens is intensely pleasurable.
