General description

Galanin (2-11) is a galanin receptor type 2 agonist.

Biochem/physiol Actions

Studies in mice show that injection of galanin (2-11) has anticonvulsant activity in seizure affected animals with an intact DR (dorsal root)–hippocampal serotonergic profile, and has no effect in animals with absent 5-HT (hydroxytryptamine) profile.

Andrey M Mazarati et al.
Journal of neurochemistry, 95(5), 1495-1503 (2005-10-13)
The neuropeptide galanin suppresses seizure activity in the hippocampus by inhibiting glutamatergic neurotransmission. Galanin may also modulate limbic seizures through interaction with other neurotransmitters in neuronal populations that project to the hippocampus. We examined the role of galanin receptors types
Xiaoying Lu et al.
Neuropeptides, 39(3), 165-167 (2005-06-10)
The neuropeptide galanin regulates a variety of physiological and pathophysiological processes through three G protein coupled receptors, GalR1, GalR2, and GalR3. The studies on galanin receptor subtype specific effects have been hampered by the lack of high affinity subtype selective
