对发烧的病人,临床医师常检查末梢血白细胞计数和分类。正常成人末梢血中的白细胞主要是中性粒细胞。那么中性粒细胞有何功能呢?中性粒细胞主要担当着体内“警戒”和“巡逻”的任务。它监视的对象主要是侵入体内的异物,特别是细菌。细菌入侵时,菌体的某些成分或血清里产生出来的某些物质,就会向中性粒细胞发出信息,让它向细菌存在的部位作定向的移动,并聚集于该处,犹如鱼儿游向食饵。中性粒细胞被吸引,聚集的过程叫“趋化作用”。中性粒细胞接 For fever patients, clinicians often check the peripheral blood leukocyte count and classification. The white blood cells in peripheral blood of normal adults are mainly neutrophils. So what is the function of neutrophils? Neutrophils play the main role of “alert” and “patrolling” in the body. It monitors the main target of foreign body intrusion, especially bacteria. When bacteria invade, certain components of the cell body or some of the material produced in the serum send a message to the neutrophils that they can be targeted for movement to the site where the bacteria are present and to gather there as a fish Children swim to bait. Neutrophils are attracted, the process of aggregation called “chemotaxis.” Neutrophil access
