Interleukin-6-deficient (IL-6(-/-)) knockout mice had significantly increased Chlamydia trachomatis levels in lung tissue and increased mortality compared to B6129F2/J controls early after intranasal infection. Gamma interferon production and chlamydia-specific antibody levels were consistent with a decreased but reversible Th1-like response in IL-6(-/-) mice. IL-6 is needed for an optimal early host response to this infection.
与B6129F2/J对照相比,白细胞介素-6缺陷(IL-6(-/-))基因敲除小鼠在鼻内感染后早期,肺组织中的沙眼衣原体水平显著升高,死亡率也更高。γ干扰素的产生和衣原体特异性抗体水平与IL-6(-/-)小鼠中降低但可逆的Th1样反应一致。最佳的早期宿主对这种感染的反应需要IL-6。
