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;它们口吃病原体,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.

I returned to my apartment and called Mother. I thought confessing would alleviate my guilt. I told her I'd seen a doctor, and that I had strep and mono. " I'm taking penicillin, " I said. " I just wanted you to know" .
我回到公寓,给母亲打了个电话。我觉得坦白会减轻自己的罪恶感。我告诉她我去看了医,我感染了链球菌和单核细胞病毒。" 我只是想让你知道," 我说," 我正在服用青霉素。"
