Abstract

When irradiated hamsters are passively immunized with immune serum before challenge with Borrelia burgdorferi, they are completely protected from arthritis and infection. The complement dependency of this protection was addressed by treating hamsters with cobra venom factor. Depletion of complement abrogated the ability of immune serum obtained 1 and 10 weeks after infection to confer complete protection. By contrast, depletion of complement had no effect on the ability of 3-week immune serum to confer protection. These results suggest that complement-dependent, and possibly complement-independent, antibodies are important for preventing the induction of Lyme arthritis.

摘要

在用伯氏疏螺旋体攻击之前,给受辐照的仓鼠被动注射免疫血清,它们可完全免受关节炎和感染。通过用眼镜蛇毒因子处理仓鼠来研究这种保护作用对补体的依赖性。补体耗竭消除了感染后1周和10周获得的免疫血清提供完全保护的能力。相比之下,补体耗竭对3周龄免疫血清的保护能力没有影响。这些结果表明,补体依赖性抗体以及可能的非补体依赖性抗体对于预防莱姆关节炎的诱导很重要。
