Abstract
Teleostean neuropeptides such as arginine vasotocin (AVT) and isotocin (IT) and their homologues arginine vasopressin (AVP) and oxytocin (OT) are implicated in the regulation of reproduction and social behaviour in vertebrates
Highlights
Teleostean neuropeptides such as arginine vasotocin (AVT) and isotocin (IT) and their homologues arginine vasopressin (AVP) and oxytocin (OT) are implicated in the regulation of reproduction and social behaviour in vertebrates[1,2,3]
AVP/OT systems affect social behaviour by acting within a complex neuronal network defined as a ‘social behavioural neuronal network’ (SBNN)[12,13]
Journal of Neurology & Neuromedicine of the reproductive cycle or social interactions can affect AVP and OT levels by their ERs, which in turn could alter the social behaviour of the individual . 19,13 Most of the research that has focused on the effect of oestradiol on the synthesis and secretion of nonapeptides has been performed in rodents
Summary
Teleostean neuropeptides such as arginine vasotocin (AVT) and isotocin (IT) and their homologues arginine vasopressin (AVP) and oxytocin (OT) are implicated in the regulation of reproduction and social behaviour in vertebrates[1,2,3]. Oestrogens, synthesized in ovaries or locally in the brain, play well-recognized roles in the neuroendocrine control of reproductive physiology, secondary sex characteristics, and sexual behaviour across vertebrate females[16,17]. In higher vertebrates and fish, there are indications of possible interactions between oestrogens and AVP/AVT- and OT/IT-ergic systems.
