Features of the cytokine profile and relationships of polymorphisms of the immune system with levels of serum cytokines in individuals exposed to chronic radiation exposure

The article presents the results of the cytokine profi le study in Techa riverside residents exposed to chronic irradiation in diff erent periods of ontogenesis, as well as the relationship of the carrier polymorphic variants of genes IL1b, IL2, IL4, IL6, IL8 and TNFα with the content of the corresponding cytokines in the blood serum of irradiated persons. The decrease in the levels of pro-infl ammatory (IL-1β, IL-2, IL-6) and anti-infl ammatory (IL-4, IL-10) cytokines was noted in Techa riverside residents, whose period of intrauterine and childhood development fell out on the time of maximum radioactive discharges relative to groups of persons irradiated only in the postnatal period. Also, the connection of polymorphic rs1800872 gene IL10 with IL-10 content in blood serum was revealed.
