    Abstract:
    The role of signaling molecules in synthesis of humoral regulators of granulocytopoiesis by the hematopoietic microenvironmental cells during stress was analyzed using specific inhibitors. The major role in stimulation of the synthesis of granulocytic CSF during stressful stimulation is played by PI3K/Akt signaling cascade. Nuclear transcription factor NF-κB plays an auxiliary role in the regulation of functional activity of the bone marrow mononuclears. However, this factor affects the synthesis of granulocytic CSF by CD4+ cells of the bone marrow in response to stressful stimulation. Different degree and specific character of involvement of the signaling proteins in the regulation of the production of humoral factors determining colony-stimulating activity are explained by changes in functional state of monocyte-derived macrophages in different periods of stress response.
