[Endocytosis by liver cells during stimulation of the mononuclear phagocyte system by yeast polysaccharides].
Endocytosis (phagocytosis, fluid-phase- and receptor-mediated endocytosis) by liver cells, lysosomal enzyme activities have been studied during macrophages stimulation by yeast polysaccharides. It was shown that like macrophages stimulator zymosan, yeast polysaccharides cryelan and rhodexman increased the carbon particles phagocytosis. The most effective was intravenous administration of yeast polysaccharides. Compared to rhodexman, the effect of cryelan was more prominent. Macrophages stimulation was followed by suppression of fluid-phase endocytosis by liver cells. Increased activity of cathepsin B was discovered on day 5 after macrophages stimulation (proteinase, most typical for macrophages enzymes).
