奶牛中性粒细胞功能活性研究进展

Research advance in bovine neutrophil function and activity

中性粒细胞(PMN)是奶牛乳房抵抗细菌感染的重要防御屏障,当乳腺感染后,PMN在细胞因子的诱导下向炎症部位聚集并发挥吞噬杀菌功能。然而,奶牛乳和血液中的PMN的功能活性却存在着差异。文章综述了PMN在奶牛体内的生长、迁移、凋亡、PMN的功能活性及其影响因素,对了解和防治奶牛乳腺炎具有一定的参考价值。

Polymorphonuclear neutrophil leukocytes （PMN） are the important defense barrier of the cow breast to resist bacterial infection. PMN can gather in the inflammation and have the function of englobement and disinfection induced by cytokine when the mammary gland is infected. But, there are differences between the milk and blood in function and activity of PMN. The growth, migration, apoptosis, function, activity and influence factors of PMN in cow were reviewed in this article. All above is applicable in the prevention and cure of cow mastitis.
