摘　　要：旨在研究DON、ZEA联合染毒对体外培养鸡脾脏淋巴细胞分泌IL-2、IL-4、IL-10和IFN-γ的影响。DON、ZEA联合染毒剂量为0.012 5μg·mL^(-1)和0.006 25μg·mL^(-1)、0.050μg·mL^(-1)和0.025μg·mL^(-1)、0.2μg·mL^(-1)和0.1μg·mL^(-1)、0.8μg·mL^(-1)和0.4μg·mL^(-1),进行DON、ZEA联合染毒48 h对鸡脾脏淋巴细胞上清液IL-2、IL-4、IL-10和IFN-γ含量及其mRNA表达的影响。结果表明,各染毒组细胞上清液IL-10和IFN-γ蛋白含量,细胞内IL-2、IL-4和IL-10 mRNA水平随毒素剂量的升高而增加(P<0.01);各染毒组细胞上清液IL-2和IL-4蛋白含量均随毒素浓度的升高而降低(P<0.01);细胞内IFN-γmRNA表达量均随毒素浓度的升高而先升高后降低(P<0.01)。DON、ZEA联合染毒导致细胞因子IL-2、IL-4、IL-10和IFN-γ分泌失衡,且呈剂量依赖性;DON、ZEA联合染毒鸡脾淋巴细胞上调或下降促炎性细胞因子的水平;Th1和Th2细胞因子平衡失调,因此造成细胞免疫损伤,从而对细胞产生毒性。The purpose of this study was to investigate the effects of DON and ZEA on the secretion of IL-2, IL-4, IL-10 and IFN-γ in cultured chicken spleen lymphocytes in vitro . The exposure doses of DON and ZEA were DON 0.012 5 μg ·mL -1 and ZEA 0.006 25 μg ·mL -1 , DON 0.05 μg ·mL -1 and ZEA 0.025 μg ·mL -1 , DON 0.2 μg ·mL -1 and ZEA 0.1 μg ·mL -1 , DON 0.8 μg ·mL -1 and ZEA 0.4 μg ·mL -1 , individually. Then, the effects of different doses of DON and ZEA on the concentrations and mRNA expressions of IL-2, IL-4, IL-10, and IFN-γ of chicken splenic lymphocytes in vitro were investigated. The results were as followed： The concentrations of IL-10 and IFN-γ, and the mRNA expressions of IL-2, IL -4, and IL -10 were increased with the DON and ZEA concentrations increasing （ P 〈0.01）. However, the concentrations of IL-2 and IL-4 were decreased with the DON and ZEA concentrations increasing （ P 〈0.01）. And the mRNA expressions of IFN -γ were increased at first and then decreased （ P 〈0.01）. DON combined with ZEA can affect the secretion of the IL-2, IL-4, IL-10 and IFN-γ with a dose-dependent. DON, ZEA combined with the spleen lymphocytes of the infected chicken to increase or decrease the level of inflammatory cytokines. The imbalance of Th1 and Th2 cytokines can result in cellular immune damage, which can be toxic to cells.
