摘要 抗生素的过度使用严重威胁着鸭产业的发展,甚至危害人类健康,因此寻找可靠的抗生素替代 物已成为当务之急。免疫增强剂可以通过提高自身非特异性免疫能力,增强机体应对病原微生物或病原 体的防御。本研究旨在对 5 种不同的免疫增强剂对绍兴雏鸭(Anas platyrhynchos)胸腺组织凋亡及免疫因 子相关基因表达的影响进行研究。将 150 只 1 日龄的绍兴雏鸭随机均分为 6 组,连续 3 d 分别于颈部皮下 注射生理盐水、绿原酸、β-葡聚糖、黄芪黄酮、未甲基化 CpG 的核苷酸(CpG-containing DNA, CpG DNA)和 鸡免疫球蛋白 G (immunoglobulin G, IgG),18 日龄采集胸腺组织,通过 qPCR 结合 Western blot 检测炎症相 关基因和凋亡基因 mRNA 和蛋白表达水平。结果发现,与对照组相比,分别注射绿原酸、β-葡聚糖、黄芪 黄酮、CpG-DNA 和鸡 IgG 的绍兴雏鸭胸腺组织中 ,B 淋巴细胞瘤 2 (B-cell lymphoma 2, Bcl2) mRNA 和蛋 白水平均显著降低(P<0.05),半胱天冬酶-3 (Caspase3)的表达水平均在不同程度上调。此外,分别注射五 种免疫增强剂后均在不同程度上提高了胸腺组织中诱生型一氧化氮合酶(inducible nitric oxide synthase, iNOS) 和 环 氧 化 酶 2 (cyclooxygenase-2, COX2) 的 表 达 水 平 ,干 扰 素 - α (interferon- α, IFN- α)、干 扰 素 - β (interferon-β, IFN-β)、白介素-1β (interleukin-1β, IL-1β)、肿瘤坏死因子 α (tumor necrosis factor-α, TNF-α)、视黄酸诱导基因Ⅰ (retinoic acid-inducible gene-Ⅰ, RIG-Ⅰ)、Toll 样受体 3 (toll-like receptor 3, TLR3)和 Toll 样受体 7 (toll-like receptor 7, TLR7)基因的 mRNA 水平均呈现不同程度的上调表达。综上所述,绿原酸、β-葡聚糖、黄芪黄酮、CpG-DNA 和鸡 IgG 可作为免疫增强剂调控鸭先天性免疫。本研究为预防鸭重要传染性 疾病提供新途径,同时也为动物生产过程中抗生素替代物的应用提供一定的参考。

Abstract:The misuse of antibiotics seriously imperils the development of duck husbandry and even endangers human health. Therefore, it is urgent to find reliable alternatives to antibiotics. Immunopotentiator can effectively increase the ability of specific immune responses to enhance the defense against microorganisms or pathogens. The aim of this study was to investigate the effects of 5 different immunopotentiators on the thymus apoptosis and immune-related gene expression in Shaoxing ducklings (Anas platyrhynchos). The 150 1-day-old Shaoxing ducklings were randomly divided into 6 groups, and saline, chlorogenic acid, β -D-glucan, astragalus flavone, nonmethylated CpG DNA and chicken immunoglobulin G (IgG), were injected subcutaneously once daily for 3 d, respectively. At the age of 18 d, the mRNA and protein expression of apoptosis and immune-related genes were detected by qPCR and Western blot. The results showed that compared with control group, the mRNA and protein levels of thymus B-cell lymphoma 2 (Bcl2) were significantly decreased during injecting chlorogenic acid, β-D-glucan, astragalus flavone, nonmethylated CpG DNA and chicken IgG, respectively (P<0.05). And the expression levels of thymus Caspase 3 showed significantly up-regulated in some extent (P<0.05). In addition, the expression level of thymus inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX2) were increased in some extent during injecting 5 different immunopotentiators, respectively. Meanwhile, compared with control group, the levels of interferon-α (IFN- α), interferon-β (IFN-β), interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), retinoic acid-inducible gene-I (RIG-I), toll-like receptor 3 (TLR3) and toll-like receptor 7 (TLR7) mRNA expression were up-regulated in some extent during injecting 5 different immunopotentiators, respectively. Taken together, chlorogenic acid, β -D-Glucan, astragalus flavone, nonmethylated CpG DNA and chicken IgG could be used as immunopotentiators to regulate duck innate immune. This study provides new insight to prevent the duck disease from pathogen infections, and provides reference for reliable alternatives to antibiotics in animal production.
