Redox-sensitive system of the antioxidant-responsive element as a new target for tuberculosis treatment

The emergence of drug-resistant TB caused by resistance to antibiotic strains of bacteria, prompted to search for new "organism-oriented" ("host-targeted") adjuvant treatment strategies. Free radical oxidation plays an important role in the development and exacerbation of the pat...
