Effects of β-glucans from Coriolus versicolor on macrophage phagocytosis are related to the Akt and CK2/Ikaros.

Abstract

Coriolus versicolor has been known to be an immune stimulator effects. For further understanding of the phagocytic activity and the intracellular mechanisms of β-glucan from C. versicolor (CVG), we examined the phagocytic activity, phosphorylation of Akt and CK2, nucleus translocation of p65 and Ikaros activity in β-glucan-treated macrophages using RT-PCR, western blotting, and IP assay. The role of Ikaros in regulating phagocytic effects of CVG was also determined using Ikaros dominant negative isoform cells. This study suggests that CK2/Ikaros are positive regulators and novel signaling pathway involved in phagocytosis and contributes to elucidating the mechanism underlying phagocytic activity induced by β-glucan.
