    Journal: Radiats Biol Radioecol; 2006; 46(3):348-73. PubMed ID: 16869167.
    Abstract:
    In the report there are present the results of monitoring of the state of immune status in the remote period after the accident at the Chernobyl Nuclear Power Plant among three groups of liquidators, which were from Moscow and the Moscow district, the Northwestern region of Leningrad district and from Krasnoyarsk territory. During the monitoring of the liquidators from different regions there was found phenotype of immune status with regional characteristics. In the Moscow district the clinical displays of immune insufficiency prevail and in the North western region the modifications of immune status prevail among liquidators. In all the groups we could see quantitative and immunoregulatory disbalance with the increase of parameters of cellular activity such as CD95+, HLA-DR+, T-activated lymphocytes, fluctuation cytotoxic cells (CD8+, CD16+), persevering disimmunoglobulinemia with differently directed modification serum of immunoglobulins at decrease B-lymphocytes. By the end of the twenty-year period after the accident we can see a similar phenotype of immune status in all the groups with increasing of the marker of late activation (HLA-DR+) and apoptotic activity (CD95+) and it is potentially dangerous regarding cancerogenesis. According to the basis of long-term monitoring there has been discovered the immune characteristic of proliferative syndrome for the first time. The monitoring of 2004 has revealed a huge similarity immune status at non-malignant growth at significant decrease CD25+ in the Northwestern region and some differences in common IgE.
