Monoaminergic regulation of the pool of erythropoietic stem cells in active and passive mouse in experimental neuroses.

We studied monoaminergic mechanisms of regulation of the pool of erythropoietic precursors in active and passive mice under conditions of conflict situation and during paradoxical sleep deprivation. It was found that in animals with different behavior subjected to experimental neuroses the regulatory effects of CNS monoamines on proliferation and differentiation are mediated via adrenergic and erythropoietin-sensitive structures on erythroid stem cells. The revealed intergroup differences in precursor proliferation and differentiation rates (and erythrokaryocyte content in the bone marrow) are related to peculiarities in the activity of monoaminergic system and their interaction with peripheral structures on erythropoietic precursors.
