Abstract

Stress caused by 48 h food and water deprivation provoked significant changes in T3 and serotonin content of lymphocytes. The concentration of these hormones decreased in the last hour of stress. However, 48 h later there was no difference between the hormone content of immune cells of stressed and control animals. Since in earlier experiments three weeks after exposed to stress a significant difference between the control and stressed animals was found, this means that an imprinting-like phenomenon happened with consequences manifested later. The most sensitive cells to acute stress are lymphocytes, however the imprinting influences all types of of the immune cells.
