Deltorphin, a heptapeptide that selectively binds to delta receptors, was intracerebroventricularly administered to mice belonging to the strains C57BL/6 and DBA/2 immediately after training in a one-trial inhibitory avoidance task. The retention performance of both strains was improved by the peptide administration, with DBA mice being more sensitive to this effect. The results show different effects of delta and mu receptor agonists on memory consolidation and of strain differences in number and/or distribution of delta opioid receptors in the brain.
Deltorphin, a naturally occurring peptide with high selectivity for delta opioid receptors, improves memory consolidation in two inbred strains of mice.

Abstract
Deltorphin, a heptapeptide that selectively binds to delta receptors, was intracerebroventricularly administered to mice belonging to the strains C57BL/6 and DBA/2 immediately after training in a one-trial inhibitory avoidance task. The retention performance of both strains was improved by the peptide administration, with DBA mice being more sensitive to this effect. The results show different effects of delta and mu receptor agonists on memory consolidation and of strain differences in number and/or distribution of delta opioid receptors in the brain.File in questo prodotto:
