The central administration of neurotensin, an endogenous hypothalamic tridecapeptide, produces a marked dose-related decrease in body temperature of mice and rats at an ambient temperature of 25 °C. This effect is even more pronounced when mice are placed at 4°C to increase the rate of decline of body temperature. Other sequelae observed after central administration of neurotensin are decreases in locomotor activity in rats and a marked dose-related enhancement in pentobarbital-induced mortality, sedation and hypothermia. This latter effect was shown to be due to a significant reduction in the metabolic degradation of the barbiturate. None of the above-mentioned effects are observed after peripheral neurotensin administration, suggesting that this peptide does not readily cross the blood-brain barrier. Neurotensin appears to be one of a growing list of neuropeptides that can affect CNS function.
