Some monocytes migrate into tissues and differentiate into macrophages, which remain in tissues and aren't found in the blood.

一些单核细胞迁移到组织中，分化成为巨噬细胞；停留在组织里，不再在血液里出现。

Other monocytes differentiate into dendritic cells, the prototypical antigen presenting cell, which roam around in the lymph, blood, and tissue.

其他单核细胞分化成树突状细胞，是典型抗原呈递细胞；在淋巴、血液和组织中游走。

Bacterial growth and death of alveolar macrophages produce powerful chemotactic factors that cause a large influx of polymorphonuclear leukocytes and monocytes from the peripheral blood.

军团菌增长及肺泡巨噬细胞产生了强大趋化因子，造成大量多形核白细胞和单核细胞从外周血涌入。

There are five different types of leukocytes: three types of granulocytes (eosinophil, basophil, and neutrophil) and two types of agranulocytes (monocyte and lymphocyte).

三种粒细胞（嗜酸性粒细胞，嗜碱性粒细胞和中性粒细胞）和两种无粒细胞（单核细胞和淋巴细胞）。

For example, Leptospira interrogans, the most common cause of leptospirosis, has adhesins, which are proteins that help this bacteria attach to the host's cells - usually epithelium, monocytes, and macrophages.

举个例子，最常见致病菌问号钩端螺旋体粘附素可以帮助细菌粘附在宿主细胞表面，通常是表皮细胞、单核细胞以及巨噬细胞表面。

The most common co-receptors that HIV uses are the CXCR4 co-receptor, which is found mainly on T-cells, or the CCR5 co-receptor which is found on T-cells, macrophages, monocytes, and dendritic cells.

最常见辅助受体包括主要分布在T细胞上CXCR4辅助受体和分布于T细胞、巨噬细胞、单核细胞和树突细胞CCR5辅助受体。

If we look at a bigger sample, like say a decilitre, then around 70% of those will be lymphocytes, 30% monocytes, and just a few polymorphonuclear cells -- PMNs -- like neutrophils.

如果我看一个更大样本，比如一分升；那么70％左右是淋巴细胞、30％是单核细胞及一些多形核细胞（PMNs），比如中性粒细胞。

Next up are the monocytes, macrophages, and dendritic cells, which are phagocytic cells - they gobble up pathogens, present antigens, and release cytokines - tiny molecules that help attract other immune cells to the area.

接着是单核细胞、巨噬细胞和树突状细胞，三者都是吞噬细胞；大口吃病原体，呈递抗原，并释放细胞因子（即帮助号召其他免疫细胞救兵来到局部微小分子）。

Unlike granulocytes, agranulocytes do not contain granules in their cytoplasm, nor do they have multi-lobed nuclei. Agrnulocytes are characterized by the presence of a single large nucleus. The two types of agranulocytes are monocytes and lymphocytes.

与粒细胞不同，无颗粒细胞在其细胞质中不含颗粒，也不具有多叶核。无颗粒细胞特征在于其存在一个大核。两种类型粒细胞是单核细胞和淋巴细胞。
