The c-fos protein is rapidly induced in hypothalamic magnocellular nuclei following hemorrhage. We used specific antibodies directed against c-fos and either vasopressin (AVP) or oxytocin (OT) neurophysin to investigate c-fos activation in individual AVP and OT neurons. AVP and OT neurons expressed c-fos in response to hypovolemic stimuli. Following a… (More)
