SPECIFICITY OF OXYTOCIN AND VASOPRESSIN IMMUNOFLUORESCENCE

Vasopressin, oxytocin and social behaviour.

Understanding the neurobiology of social behaviour in mammals has been considerably advanced by the findings from two species of vole, one of which is monogamous and pair bonds whereas the other species is promiscuous and fails to form any long-lasting social relationships. The combination of neurobehavioural studies and molecular genetics has determined behavioural differences between the two ...

Neuromodulation by Oxytocin and Vasopressin

Oxytocin (OT) and vasopressin (VP) are two closely related neuropeptides, widely known for their peripheral hormonal effects. Specific receptors have also been found in the brain, where their neuromodulatory actions have meanwhile been described in a large number of regions. Recently, it has become possible to study their endogenous neuropeptide release with the help of OT/VP promoter-driven ex...

Types of Peptide Hormones: Oxytocin and Vasopressin

Physiology of invertebrate oxytocin and vasopressin neuropeptides

Neuropeptides and regulatory peptide hormones control many developmental, physiological and behavioural processes in animals, including humans. The nonapeptides oxytocin and arginine vasopressin are produced and released by the pituitary gland and have actions on many organs and tissues. Receptive cells possess particular receptors to which the peptides bind as ligands, leading to activation of...

Electrophoretic studies of oxytocin and vasopressin.

Recently a highly potent preparation of vasopressin has been obtained from beef posterior pituitary glands and the amino acid composition of this material has been established (2). Reef vasopressin resembles oxytocin in that six of the eight constituent amino acids are identical; however, vasopressin differs from oxytocin in that it contains arginine and phenylalanine in place of the leucine an...
