衣原体感染可诱发机体产生体液免疫、细胞免疫两种形式的免疫应答。衣原体能持续地潜伏于宿主细胞内与免疫系统的功能状态有关。在其感染过程中有改变某些免疲应答的能力,感染早期免疫应答增高,晚期则降低。干扰素可以限制免疫系统与衣原体间的相互作用,使细胞内衣原体保存下来,免疫力降低时,衣原体再次增殖。 Chlamydial infection can induce the body to produce humoral immunity, cellular immunity in both forms of immune response. Chlamydia can continue to lurk in host cells and the immune system’s functional status. In the course of their infection, they have the ability to change some of their fatigue-free responses, with an early increase in the immune response and a decrease in later stages. Interferon can limit the interaction between the immune system and chlamydia, so that intracellular chlamydia preserved, immunocompromised, chlamydia proliferate again.
