This article presents data on such a well-known fungus as Ganoderma Lucidum and its effect on the state of oxidative stress. As is known, under oxidative stress, altered Toll receptors cannot independently recognize microbial agents due to the altered chemical formula of L-galactosamine and thus mediators are not activated. It is also known that Ganoderma Lucidum due to β-polyglucans, which by chemical formula are close to this glycoprotein, can interact with leukocyte receptors and increase the adhesion molecules and leukocyte migration. Modern histological, ultrastructural and biochemical research methods are used. The results are presented and the corresponding conclusions are drawn.
