We previously reported that the fungal particle 1,3-β-D-glucan derived from Candida albicans, a pathogenic fungus, was obtained by oxidation of the cell wall with sodium hypochlorite (NaClO). It could be solubilized by treatment with dimethylsulfoxide (DMSO). In the present study, we prepared Candida 1,3-β-D-glucan having different physical properties, and examined the relationship between leukocyte activation and the physicochemical properties. β-glucan activated leukocytes significantly more effectively in a particulate than solubilized form in terms of TNF-α production by RAW 264.7 cells, hydrogen peroxide production by murine PEC and IL-8 production by human PBMC. Furthermore, we compared the biological activity of the glucan particles oxidized under various conditions. Interestingly, inactive and antagonistic particles were obtained under strong oxidation conditions. However, the inactive particles showed significant agonistic activity on dissolution in DMSO and following lyophilization. These facts strongly suggested that the solubility and assembly of the components influence the immunopharmacological activities of 1,3-β-D-glucans.
