β-Glucan Improves Conditions of Chronic Fatigue in Mice by Stimulation of Immunity

Abstract

Background: Various natural molecules have been studied for the enhancement of physical endurance. Glucan has been found to improve various stress-related conditions and to improve fatigue and endurance. Objective: In our study, we focused on evaluation of glucan effects on some reactions involved in chronic fatigue. Methods: We measured phagocytosis of neutrophils, the production of IL-2, IL-4, and IL-10 by spleen cells, and levels of antioxidant glutathione and oxidative stress marker superoxide dismutase in brain. In addition, we measured the effects of glucan on water immersion and on rotarod. Results: The glucan supplementation strongly improved the suppressed phagocytosis and changes in cytokine and levels of oxidative stress markers caused by fatigue. In addition, glucan supplementation also increased the motor functioning of tested animals. Conclusion: Our data suggested that anti-fatigue properties of glucan are related with its well-established effects as stimulator of immune reactions. © 2020 Vetvicka and Vetvickova.
