Abstract

Injected recombinant interleukin-6 (IL-6), tumour necrosis factor (TNF) and IL-1 all protect mice against experimental infection with Listeria monocytogenes. We have therefore investigated the interaction of these cytokines during infection. Treatment with recombinant (r)IL-6 enhanced TNF production by spleen cells during the first 2 days of infection. Anti-TNF antibody could totally abolish the protective effect of rIL-6, while the optimal protective function of TNF could not be achieved when IL-6 was neutralized by anti-IL-6 antibody. IL-1 induced a high level of IL-6 in the serum a short time after its administration, and neutralization of IL-6 totally abolished the protective function of rIL-1. The results thus provide further evidence for the complexity of cytokine interaction.

摘要

注射重组白细胞介素-6(IL-6)、肿瘤坏死因子(TNF)和IL-1均可保护小鼠抵御单核细胞增生李斯特菌的实验性感染。因此,我们研究了这些细胞因子在感染过程中的相互作用。在感染的头两天,用重组(r)IL-6处理可增强脾细胞产生TNF。抗TNF抗体可完全消除rIL-6的保护作用,而当IL-6被抗IL-6抗体中和时,TNF的最佳保护功能无法实现。IL-1给药后短时间内可诱导血清中高水平的IL-6,而IL-6的中和可完全消除rIL-1的保护功能。这些结果进一步证明了细胞因子相互作用的复杂性。
