摘要: 嗜中性粒细胞是防止病原入侵的第一道防线, 且已有研究表明嗜中性粒细胞在奶牛乳腺免疫中发挥着关键作用。文章运用双向凝胶电泳方法对临床型乳房炎奶牛与健康奶牛嗜中性粒细胞差异表达蛋白质组进行分析, 成功获得分辨率较高、重复性较好的奶牛嗜中性粒细胞双向电泳凝胶图谱, 并通过MALDI-TOF MS鉴定获得差异表达的蛋白质7种, 主要涉及细胞代谢、氧化应激、炎症反应等相关蛋白通路。实验获得的临床型乳房炎奶牛与健康奶牛嗜中性粒细胞差异表达蛋白有望为今后奶牛乳房炎的抗病育种研究提供理论依据。

Abstract: Neutrophils provide the first line of defense against invading pathogens and have been reported to play a key role in bovine mammary immune. To examine the differential expression of proteins in neutrophils between clinical mastitis and healthy dairy cows, a 2-dimensional electrophoresis gel map with high repeatability was constructed for bovine neutrophils. From this map, seven differentially expressed proteins were identified by MALDI-TOF MS which are believed to be involved in pathways such as cell metabolism, oxidative stress, and inflammatory reaction. The differentially expressed proteins identified in this study may provide the basis for bovine mastitis resistance breeding research.
