ABSTRACT

Soluble β-glucan preparation from the cold NaOH extract of Sparassis crispa (SCG) is a six-branched 1,3-β-D-glucan that is a major cell-wall structural component in fungi. Leukocytes from DBA/2 mice are highly sensitive to SCG, producing cytokines in vitro. We previously reported that the intraperitoneal (i.p.) administration of β-glucan decreased cytokine induction by SCG in vitro in DBA/2 mice. In this study, we examined the effects of the oral (p.o.) administration of polysaccharide fractions extracted from S. crispa, using hot water (SCHWE), a β-glucan from S. crispa, to DBA/2 mice on cytokine induction by SCG in the spleen in vitro. The level of induction of IFN-γ and GM-CSF by SCG was significantly increased in SCHWE-treated mice. This activity was more clearly observed when chlorpromazine was administered as a pretreatment in SCHWE-treated mice. The production of GM-CSF, IFN-γ, and IL-6 by immune cells in Peyer's patches was higher in SCHWE-treated mice than in control mice. These results suggest that orally administered β-glucan may modulate cytokine induction by SCG in the spleen through the activation of Peyer's patches.#947; and GM-CSF by SCG was significantly increased in SCHWE-treated mice. This activity was more clearly observed when chlorpromazine was administered as a pretreatment in SCHWE-treated mice. The production of GM-CSF, IFN-
