巨噬细胞系统和粒细胞不同,它以比较幼稚的状态从骨髓进入血流,然后再进入组织,在那里增大游出,进行一、二次分裂,并产生溶酶体,线粒体和这些细胞器所包含的酶。这种被“激活”的巨噬细胞具有增强了杀死或抑制在细胞内侵犯的细菌(象结核菌之类)的能力。巨噬细胞一旦获得这种抗性,并不特异地针对引起这一抗性的细菌,而对于多种的细胞内的细菌都有效。 The macrophage system, unlike granulocytes, enters the bloodstream from the bone marrow in a more naive state and then re-enters the tissue, where it increases in size and undergoes primary and secondary divisions and produces lysosomes, mitochondria and these organelles Enzymes included. Such macrophages that are “activated” have the ability to enhance the ability of bacteria, like tuberculosis, to kill or to inhibit intracellular invasion. Once acquired, such macrophages do not specifically target the bacteria that cause this resistance and are effective against a wide variety of intracellular bacteria.
