Аннотация: Cytokines and growth factors exhibit neurotropic, anti-inflammatory and immunomodulatory properties, and therefore can affect the functioning of the nervous system at demyelinating disorders. Purpose. To identify changes in T-lymphocytes, macrophages, oxidative stress and antioxidant defence factors, endocrine thymus function in the brain and behaviour of mice receiving neurotoxin cuprizone and recombinant human proteins: interleukin-10 (rhIL-10) and fibroblast growth factor (rhFGF-2). Materials and methods. 4-6-month-old 129/Sv mice received cuprizone with food every day for 3 weeks. From the 7th day of cuprizone diet, they received different doses of rhIL-10 and rhFGF-2. The content of СD3+ Т-cells, macrophages, malondialdehyde, activity of antioxidant enzymes in the brain and the level of thymulin in the blood were determined. Behavioural reactions were assessed in the “open field” test. Results. In the brain of mice receiving cuprizone and rhIL-10, there was a decrease in the number of СD3+ Т-cells and the activity of macrophages, which significantly increased under the influence of the toxin. After cytokine injection, the activity of superoxide dismutase, catalase and glutathione peroxidase increased significantly in the brain, as well as the level of thymulin in the blood. Motor, emotional and exploratory activity of mice, significantly suppressed by the cuprizone, was increased after the introduction of rhIL-10. The effect of rhIL-10 on the test parameters is more pronounced at a dose of 5 μg/kg than 50 μg/kg. After injection of rhFGF-2 in the mice with cuprizone diet, there is a decrease in the activity of brain macrophages and an increase of the level of thymulin in the blood depending on the dose of this factor; the motor activity of these animals increased regardless of the rhFGF-2 dose. Conclusion. The injections of rhIL-10 and rhFGF-2 provide dose-dependent positive effects on the pathogenetic factors of experimental demyelinating pathology, as well as the functional state of the nervous system. Whereas, the injections of rhIL-10 have more pronounced effects. Доп.точки доступа: Labunets, I. F. Rodnichenko, A. E. Utko, N. A. Panteleimonova, Т. М. Pokholenko, Ya. O. Litoshenko, Z. L.
