Abstract:

This study was aimed to explore the effect of compound Chinese herbal medicinal polysaccharides (cCHMPS) on immunomodulatory in different MHC B-LβⅡ genotype chickens.MHC B-LβⅡ genotype was analyzed by PCR-SSCP method in 500 chickens.Collected the blood from different MHC B-LβⅡ genotype chickens,isolated peripheral blood lymphocytes,and added cCHMPS with the final concentration of 200,100,75,50,25 and 0 μg/mL cocultured for 24 h.Then the lymphocyte supernatant cAMP,cGMP,Ca2+,NO and iNOS content were detected by ELISA.The results showed that cCHMPS could increase cAMP,cGMP,Ca2+,NO and iNOS levels in chicken lymphocyte supernatant compared with control group in each MHC B-LβⅡ genotype chickens.And when the concentration of cCHMPS was 50 μg/mL,cAMP,Ca2+,NO and iNOS levels of AA and BC genotypes chicken lymphocyte supernatant were higher than that of the same genotype chicken,cGMP level of BC genotype chicken lymphocyte supernatant was higher than that of the same genotype chicken;When cCHMPS concentration was 75 μg/mL,cGMP level of AA genotype chicken lymphocyte supernatant was higher than that of the same genotype chicken;When cCHMPS concentration was 100 μg/mL,cAMP,cGMP,Ca2+,NO and iNOS levels of BB genotype chicken lymphocyte of the supernatant were higher than that of the same genotype chicken.cCHMPS could increase cAMP,cGMP,Ca2+,NO and iNOS levels in different MHC B-LβⅡ genotypes chickens,and the cCHMPS optimum immunomodulatory doses were different in each MHC B-LβⅡ genotypes chickens.

Key words: compound Chinese herbal medicinal polysaccharides (cCHMPS); MHC B-LβⅡ gene; chicken lymphocyte; immune signal molecules
