Abstract

We investigated the role of interleukin-10 (IL-10) in a neonatal mouse model of lethal group B streptococci (GBS) sepsis. Plasma IL-10 levels significantly increased at 24 and 48 h after GBS inoculation. Neutralization of IL-10 with specific antibodies had no effect on lethality. Administration of recombinant IL-10 at 20 or 4 h before challenge, but not at later times, resulted in decreased tumor necrosis factor alpha levels and improved survival. IL-10 could be potentially useful for the treatment of GBS sepsis.

摘要

我们在致死性B族链球菌(GBS)败血症的新生小鼠模型中研究了白细胞介素-10(IL-10)的作用。接种GBS后24小时和48小时,血浆IL-10水平显著升高。用特异性抗体中和IL-10对致死率没有影响。在攻击前20小时或4小时给予重组IL-10,但在更晚的时间给予则无效,这导致肿瘤坏死因子α水平降低并提高了生存率。IL-10可能对GBS败血症的治疗有用。
