We studied the immunological status and polymorphic variants of candidate genes in men with disturbances of autonomic nervous regulation under conditions of aerogenic exposure to benzene. The group of men with pathology of the autonomic nervous system (autonomic dysfunction syndrome) living under conditions of aerogenic exposure to benzene is characterized by increased blood contamination with benzene, which 1.5-fold surpassed this parameter in the group of conventionally healthy men (p<0.05). The immune profile of the surveyed men is characterized by increased specific sensitization (IgG to benzene) and activation of apoptosis (TNFR, p53) and phagocytosis. The production of serum IgA was also increased (p<0.05) in men of this group. The content of CD127— lymphocytes significantly (p<0.05) exceeded the reference level against the background of a significantly reduced (p<0.05) level of CD3+CD95+ lymphocytes irrespective of the presence or absence of autonomic nervous system pathology in men with excessive haptenic load with benzene. The revealed features of the immune status of men with autonomic regulation disorders were significantly associated (OR>1; p<0.05) with the variant allele of the FOXP3 immune regulation gene (rs3761547) and with wild-type allele of the SOD2 superoxide dismutase gene (rs2758330) and the corresponding homozygous genotypes. The established features of immune regulation (hyperproduction of IgG to benzene, imbalance of apoptosis markers (CD127—, CD3+CD95+, p53, and TNFR) against the background of altered polymorphism of candidate genes (FOXP3, SOD2) form a complex of genetic and immunological markers of autonomic regulation disorders in men living under conditions of aerogenic exposure to benzene.
