摘要/Abstract

摘要： 分别应用复合黏膜免疫佐剂Ⅰ和Ⅱ与新城疫Ⅳ系弱毒苗混合（佐剂Ⅰ组和佐剂Ⅱ组），经口免疫鸡后，研究鸡小肠黏膜局部CD3+T细胞、上皮内淋巴细胞和干扰素-γ（Interferon-γ，IFN-γ）mRNA表达水平的变化。结果表明，在整个免疫期内CD3+T细胞和上皮内淋巴细胞数量都呈上升趋势，在首免后第3和第5周时十二指肠CD3+T细胞佐剂Ⅱ组比佐剂Ⅰ组显著增加（P<0.05），空肠CD3+T细胞佐剂Ⅱ组比佐剂Ⅰ组极显著增加（P<0.01），第7周时Peyer’s斑上皮内淋巴细胞佐剂Ⅱ组比佐剂Ⅰ组极显著增加（P<0.01）；整个免疫期内佐剂Ⅱ组和佐剂Ⅰ组IFN-γ mRNA表达水平呈下降趋势，表达量较低。本研究表明2种复合黏膜免疫佐剂都能明显增加黏膜局部免疫细胞的数量，提高小肠局部黏膜免疫力。

Abstract: The chicken were immunized orally with NDV strain LaSota vaccine containing two kinds of compound mucosal immune adjuvant(Group adjuvant Ⅰ and Ⅱ) respectively. The CD3+T lymphocytes, intraepithelial lymphocytes(IEL) and IFN-γ mRNA expression of small intestine in chicken were investigated. The results showed that the number of CD3+T lymphocytes and IELs increased during the period of immunity. The number of CD3+T lymphocytes of Group adjuvant Ⅱ were higher than that of Group adjuvant Ⅰ (P<0.05) in duodenum and significantly higher (P<0.01) in jejunum at the 3rd week and 5th week after vaccination. The number of IELs of Group adjuvant Ⅱ were significantly higher than that of Group adjuvant Ⅰ (P<0.01) in Peyer’s Patch at the 7th week after vaccination. The IFN-γ mRNA expression of two compound adjuvant groups decreased after vaccination. The results demonstrated that compound adjuvants could induce high level cellular immune response and promote intestine mucosal immunity in chicken.
