Arginine-vasopressin (AVP) is a nonapeptide of hypothalamic origin that has been shown to exert many important cognitive and physiological functions in neurons and terminals of both the central and peripheral nervous system. Here we report for the first time that AVP induced an increase in intracellular Ca2+ concentration in non-neuronal cells isolated from the rat dorsal root ganglion (DRG) and cultured in vitro. Our results suggest that AVP modulates the activity of DRG glial cells via activation of V1a receptor.
