[Effects of the interaction of serotonin with cells].

On the process of rosette-formation in CBA mice, biological effect of serotonin interaction with enriched T-lymphocytes by cells (ETLC), got from blood leukocytes and with peritoneal adhering cells (AC) has been studied. Participation of n. vagus in realization of serotonin-induced helper effect of ETLC and participation of hypothalamo-hypophysial-adrenal complex in realization of serotonin-induced suppressor effect of AC have been shown.
