Structure and biological activities of beta-glucans from yeast and mycelial forms of Candida albicans.
We have achieved the extraction of cell wall beta-glucan from the mycelial form of Candida albicans (C. albicans) IFO 0579 (M-CSBG) by using acetic acid, sodium hypochlorite (NaClO), and dimethylsulfoxide (DMSO) treatments. The yield of M-CSBG was significantly lower (7.5% from dried mycelial cells) than that of the yeast form from C. albicans IFO 1385 (Y-CSBG, 25.9% from dried yeast cells). The properties of M-CSBG were similar to those of Y-CSBG in terms of nuclear magnetic resonance (NMR) spectra and limulus reactivity. Molecular weight (Mw) of M-CSBG was slightly higher than that of Y-CSBG. Both Y-CSBG and M-CSBG induced the production of comparable amounts of macrophage inflammatory protein-2 (MIP-2), a chemotactic factor, from mouse peritoneal exudate cells (PEC) in vitro. These findings suggest that the structure and properties of CSBG from yeast and mycelial cells are similar to each other.
