title: The effect of "facteur thymique serique" (FTS) on catecholamine and serotonin neurotransmission in discrete brain regions of mice.
abstract: The dose-related effect of Facteur Thymique Serique (FTS) on hypothalamic, mesencephalic and striatal neurotransmission were investigated after intracerebroventricular (icv) administration. FTS pretreatment with dose of 1 microgram (icv) increased the mesencephalic serotonin content, while failed to influence the hypothalamic and striatal serotonin levels. The nonapeptide in a dose of 0.1 microgram (icv) decreased the hypothalamic, while in a dose of 1 microgram the hypothalamic and also the mesencephalic dopamine content, but did not influence the striatal dopamine level. FTS in a dose of 1 microgram (icv) significantly decreased the hypothalamic noradrenaline level, but did not influence the noradrenaline content of the mesencephalon and striatum. These results suggest that FTS is able to modify central neurotransmission.
