Abstract:

In order to explore the effect of compound Chinese herbal medicines polysaccharides(cCHMPS) on immunomodulatory in different MHC B-Lβ Ⅱ genotype chickens,200 White feather broiler were chosen and PCR-SSCP technique was applied to analyze the polymorphism of MHC B-Lβ Ⅱ gene. The peripheral blood were collected according to the different MHC B-Lβ Ⅱ genotype,and the lymphocytes were isolated from peripheral blood and the cCHMPS were added with a final concentration of 100,75,50 and 0 μg/mL for co-culturing 24 h.Then the expression of NF-κB,TNF-α,IL-6 mRNA in lymphocyte using Real-time PCR method were detected. The results showed that:Compared with the control group,different does of cCHMPS could significantly improve NF-κB,TNF-α,IL-6 mRNA expression levels in chicken with different MHC B-Lβ Ⅱ genotypes (P<0.05), and when the cCHMPS concentration was 50 μg/mL,the NF-κB,TNF-α,IL-6 mRNA expression levels in lymphocyte of AB and AA genotype chicken were significantly higher than that of other groups (P<0.05).The NF-κB,IL-6 mRNA expression levels of AC genotype chicken were significantly higher than the other groups (P<0.05). The TNF-α mRNA expression levels of AC genotype chicken were significantly higher than the other groups when cCHMPS was 100 μg/mL (P<0.05).There results indicated that the cCHMPS could stimulate NF-κB,TNF-α,IL-6 mRNA expression in different MHC B-Lβ Ⅱ genotype chickens,and the optimum immunomodulatory does were different in each MHC B-Lβ Ⅱ genotype chicken.

Key words: compound Chinese herbal medicines polysaccharides (cCHMPS); MHC B-Lβ Ⅱ genotype; chicken lymphocyte; cytokines
