Abstract

The effect of phenolic antioxidant 3-(3'-tert-butyl-4'-hydroxyphenyl) propylthiosulphonate sodium (TS-13), which is an activator of redox-sensitive system Keap1/Nrf2/ARE, is investigated in the model of BCG vaccine intravenous injection. Granulomas of presumably macrophagic type were formed in liver of BALB/c mice at day 30 after infection, activity of free-radical oxidation processes in liver enhanced too and directly correlated with the granuloma numerical density and diameter. Activity of free-radical oxidation processes as well as granuloma formation significantly decreased in animals which received TS-13 (100 mg/kg body weight) in drinking water, whereas generation of reactive oxygen species by peritoneal exudate phagocyte increased. The data indicate the involvement of Keap1/Nrf2/ARE system in granulomogenesis and the dichotomy of the body reaction to it.

Key words
