Outline of Final Research Achievements

We examined the effects of early-life social stress (deprivation of social play) upon food intake and body weight in adulthood of rats. Social play induced the activation of oxytocin neurons in the paraventricular hypothalamic nucleus. Oxytocin neurons in the paraventricular hypothalamic nucleus were also activated in the observer rats (which observed playing cagemates). Contrary to our expectations, food intake and body weight of chronic social stressed rats were not significantly different from control rats.
We generated two transgenic rat strains that express human diphtheria toxin receptor under the control of the oxytocin promoter and express human interleukin-2 receptor alpha-subunit under the control of the prolactin-releasing peptide (PrRP) promoter. We succeeded in site-specific destruction of oxytocin neurons or PrRP neurons by local injection of diphtheria toxin or immunotoxin in transgenic rats.
