title: Dose-related effects of cysteamine treatment on hypothalamic and striatal dopamine, noradrenaline and serotonin neurotransmission.
abstract: The dose-related effects of cysteamine treatment on hypothalamic and striatal neurotransmission were investigated. Cysteamine pretreatment with a dose of 150 mg/kg slightly increased the dopamine, and markedly decreased the noradrenaline, content of the hypothalamus in a dose-related manner. The serotonin levels of the hypothalamus and striatum were not affected. Cysteamine pretreatment with a higher dose (300 mg/kg sc) slightly increased the uptake of noradrenaline into hypothalamic slices. The drug did not influence dopamine and serotonin uptake into hypothalamus and striatal slices. These results suggest that cysteamine decreases rather selectively the noradrenaline content of the hypothalamus.
