Introduction: Maternal deprivation (MD) during neonatal life has diverse long-term effects, including modification of metabolism. Some of these effects are sexually dimorphic. We have previously reported that MD in rats blocks the physiological neonatal leptin surge, which could underlie the long-term metabolic changes.Hypothesis: We hypothesized that replacement of leptin during MD would normalize long-term endocrine changes.Metho...
