Salmonella Gallinarum 감염닭의 대식세포에서 표고버섯 균사체 발효 미강생물전환소재에 의한 면역조절효과

초록

In this study, we investigated the effect of bioprocessed polysaccharides (BPPs) from the liquid culture of Lentinus edodes fungal mycelia containing rice bran (BPP-RB) on a chicken-derived macrophage cell line, HD-11, when infected with Salmonella Gallinarum, an etiological agent of fowl typhoid. Experimental results demonstrated water extract of BPP-RB did not show growth inhibitory effects on S. Gallinarum 277. Protein expression profiles were also not altered by its treatment. Nonetheless, it could (i) enhance phagocytic activity of HD-11 cells, (ii) activate the transcriptional expression of Th1-type cytokines such as tumor necrosis factor-α and interleukin (IL)-1β, iNOS, as well as an immunosuppressive cytokine IL-10, and (iii) negatively regulate Th2-type cytokines such as IL-4 and IL-6. Together results suggest that BPP-RB may be applicable for preventing fowl typhoid or other Salmonella infections in poultry farms as a potential feed additive.
