Abstract

The first encounter between the developing receptor and its target hormone establishes the hormonal imprinting which is needed for the normal function of the cell. In the presence of foreign-however able to bind-molecules, faulty imprinting develops with lifelong consequences. Hormonal imprinting influences not only the receptors, but also the later hormone production of cells. The critical time of hormonal imprinting is the perinatal period, however it can be executed sometimes (in continuously differentiating cells) also at puberty. As in earlier experiments single neonatal serotonin treatment caused a life-long alteration of white blood serotonin content in female rats, the early (10-19 day) and late (8 weeks) effect of single pubertal serotonin treatment was studied presently, by using flow cytometry. In contrast to the earlier (neonatal) results, pubertal treatment caused a radical reduction of serotonin content in male's lymphocytes, monocytes, granulocytes and mast cells, independent on the time of study. The effect in females was rather increasing, however uncertain. The experiments call attention to the possible different effects of neonatal and pubertal hormonal imprinting and to the imprintability of blood cells in adolescence.
