A novel B-2 suppressor cell regulating susceptibility/resistance of mice to Toxoplasma gondii infection.

abstract：:β-1,3-glucan is a major component of fungal cell walls with various biological activities, including effects on the production of inflammatory mediators in vivo and in vitro. However, few reports have examined its influence on the fungal cell itself. In this study, the influences of β-1,3-glucan on the growth and cell...
