Neutrophils are the most abundant type of white blood cells in the human body, constituting around 50-70% of all leukocytes.
中性粒细胞是人体内最丰富的白细胞类型,约占所有白细胞数量的50-70%。
During an infection,
neutrophils are rapidly recruited to the site of inflammation where they engulf and destroy pathogens.
在感染期间,中性粒细胞会迅速聚集到炎症部位,吞噬并消灭病原体。
Neutrophils play a crucial role in the innate immune system by phagocytosing bacteria, viruses, and other foreign substances.
中性粒细胞通过吞噬作用清除细菌、病毒和其他外来物质,在固有免疫系统中发挥着关键作用。
The increase in the number of circulating
neutrophils is often indicative of a bacterial infection or acute inflammation.
循环中性粒细胞数量的增加通常意味着存在细菌感染或急性炎症。
Neutrophils contain granules filled with enzymes that help them break down microorganisms once they have been engulfed.
中性粒细胞含有充满酶的颗粒,有助于它们吞噬微生物后对其进行分解。
In a complete blood count test, a high
neutrophil count is referred to as
neutrophilia while a low count is called neutropenia.
在全血细胞计数测试中,中性粒细胞计数高被称为中性粒细胞增多症,而低计数则称为中性粒细胞减少症。
Chemotaxis enables
neutrophils to migrate towards sites of infection guided by chemical signals released from damaged tissues.
趋化性使得中性粒细胞能够根据受损组织释放的化学信号向感染部位迁移。
Neutrophils can also release
neutrophil extracellular traps (NETs) to ensnare and kill pathogens in their vicinity.
中性粒细胞还能释放中性粒细胞外陷阱(NETs),以捕获并杀死其周围的病原体。
Patients undergoing chemotherapy often experience neutropenia due to the drugs' toxic effects on bone marrow where
neutrophils are produced.
接受化疗的患者由于药物对产生中性粒细胞的骨髓产生的毒性效应,常常出现中性粒细胞减少的情况。
The lifespan of a typical
neutrophil in the circulation is about 6 to 24 hours before it undergoes programmed cell death or apoptosis.
典型的循环中性粒细胞寿命约为6至24小时,之后将经历程序性细胞死亡或凋亡。
