| Abstract: | Coriolus versicolor (C. versicolor) is a higher fungi or mushroom which is now known by its accepted scientific names as Trametes versicolor (L.) Lloyd. Many studies have shown that β-glucans from C. versicolor have various physiological activities, including activating macrophages to protect against Salmonella infection. However, whether β-glucans have antiviral effects has not been reported. Hence, the objective of this study was to confirm whether β-glucans could boost the immune response to combat influenza virus in mouse and chick models. The results show that β-glucans induced the expression of Dectin-1, costimulatory molecules (CD80/86) and cytokines IL-6, IL-1β, IFN-β and IL-10 in murine bone marrow dendritic cells (BMDCs). In addition, orally administered β-glucans reduced weight loss, mortality and viral titers in the lungs of mice infected with influenza virus and attenuated pathological lung damage caused by the virus in the mice. Orally administered β-glucans improved survival and reduced lung viral titers in chickens infected with H9N2 avian influenza virus. These results suggest that β-glucans have a significant antiviral effect. Therefore, β-glucans could become a potential immunomodulator against influenza virus. |
