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

一些单核迁移中，分化成为巨噬；它们会停留在里，不会再在血液里出现。

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

其他单核会分化成树突状，是典型的抗原呈递；它们会在淋巴、血液中游走。

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.

军团菌的增长及肺泡巨噬的死亡产生了强大的趋化因子，造成大量多形核白单核从外周血涌入。

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（嗜酸性粒，嗜碱性粒中性粒）两种无粒（单核淋巴）。

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，最常见的致病菌问号钩端螺旋体的粘附素可以帮助菌粘附在宿主表面，通常是表皮、单核以及巨噬的表面。

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.

最常见的辅助受体包括主要分布在T上的CXCR4辅助受体分布于T、巨噬、单核树突的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.

如果我们看一个更大的样本，比如一分升；那么70％左右是淋巴、30％的是单核及一些多形核（PMNs），比如中性粒。

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、巨噬树突状，三者都是吞噬；它们大口吃病原体，呈递抗原，并释放因子（即帮助号召其他免疫救兵来局部的微小分子）。

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.

与粒不同，无颗粒在其质中不含颗粒，也不具有多叶核。无颗粒的特征在于其存在一个大核。两种类型的粒是单核淋巴。
