Abstract :

Ionizing radiation influence is accompanied by changes in immune system at cellular and subcellular level, causingdevelopment dysfunction and secondary immunodeficiency. The decrease of immune control, including anti-tumor defense, testifies to the need of medical-immunological examination of exposed individuals. It will enable the development of approaches for immunocorrection and prophylaxis of immune disorders at pre-clinical stage of oncopathology and other somatic pathology. We consider it prospective to detect early informative radiation-induced markers of immune disorders and to form risk groups for personified follow-up. Immune homeostasis factors were studied in over 600 individuals (workers exposed to external γ- and internal α-radiation exposure in different doses or residents who never worked at nuclear enterprise). Using ELISA we defined the level of 30 regulatory proteins of different mechanisms in blood serum. Changes in protein content depending on type, dose and duration of exposure (growth factors TGFβ1, EGF, Ang-1, HER-2 etc., multifunctional interleukins and their receptors) were found. We used the specimens of blood serum stored at low temperatures in SUBI Radiobiological Human Tissue Repository. Content of effector and regulatory lymphocytes (17 indices) was studied as well. Medical data about the studied individuals were collected; it will enable to assess the connection of serum and membrane proteins content deviation with somatic pathology.
