Maturation of bone marrow-derived dendritic cells by a novel β-glucan purified from Paenibacillus polymyxa JB115

초록

We investigated the immunostimulatory effects of a novel beta-glucan purified from Paenibacillus (P.) polymyxa JB115 on bone marrow-derived dendritic cells (DCs), a type of potent antigen-presenting cells. beta-glucan isolated from P. polymyxa JB115 enhanced the viability and induced the maturation of DCs. P-glucan markedly increased the cytokine production of DCs and surface expression of DC markers. In addition, DCs treated with beta-glucan showed a higher capacity to stimulate allogeneic spleen cell proliferation compared to those treated with medium alone. These results demonstrate the effect of beta-glucan on DC maturation and may increase the use of beta-glucan.
