ABSTRACT
Radioreceptor analysis showed that human beta-casomorphin-7 displaced 3H-spiperone from 5-HT2-serotonin receptors of the rat cerebral frontal cortex: EC50 8 +/- 1 microM. Human and bovine beta-casomorphin-7 dose-dependently blocked serotonin-induced human platelet aggregation: IC50 5 +/- 1 and 20 +/- 4 microM, respectively. It was proved that beta-casomorphins-7 act as 5-HT2-serotonin receptor antagonists; one of the mechanisms of their biological effects is presumably associated with modulation of the serotoninergic system.
