| Research Abstract |
The culture fluid of entomogenous fungi including genus Paecilomyces and Cordyceps promotes ileal immune responses in murine Peyer’s patch cells ex vivo, and their constituents were identified as glycoprotein, molecular mass was up to 17 kD, containing 8 amino acids and β（1→3）glucan. The detail analyses of chemical structures of glycoprotein revealed that the glycoprotein was mixture of peptides (approximately 70% glucans and 25% peptides including amino acids monomer). Proanthocyanidins, stilbenoids or garlic extract, which are frequently used as health foods of entomogenous fungi, also showed a potentiating activity on ileal immune responses. These data suggested that some entomogenous fungi and the mixture of glucan and peptides have an adjuvant activity.
