Abstract |
The objective of the current study is to investigate the protective effect of carboxymethylpachymaran ( CMP) on the immune system of mice via multiple infections with porcine circovirus type 2 (PCV2). The in vivo results showed that CMP administration significantly improved the spleen or thymus index, promoted the proliferation activities of T or B lymphocytes, and increased the production of glutathione, the superoxidase dismutase capacity, and the total antioxidant capacity in the spleen or thymus of PCV2-infected mice. The administration of different CMP doses to PVC2-inoculated mice resulted in the upregulation of IL-2 and IFN-α or the downregulation of IL-10 levels in the serum. These findings suggest that CMP has potential applications in regulating immunological functions to overcome the immunosuppresion caused by PCV2 infection in mice. The findings may also prove useful in designing effective therapies against PCV2 infection.
