Macrophages activation as the effector mechanism in destroying L. enriettii in the guinea-pig, and L. tropica in the mouse, was tested in vitro. Activated guinea-pig macrophages, with enhanced anti-Listeria capacity had no effect on the survival of intracellular L. enriettii, irrespective of the antigen used. Activated mouse macrophages, on the other hand, destroyed ingested L. enriettii within 24-48 hr but had no effect on L. tropica during the same time period. It is suggested that the pathogenicity of a Leishmania parasite in a given host depends on the ability of the parasite to survive in the host's activated macrophages. The possible mechanisms by which L. enriettii evades destruction in activated guinea-pig macrophages are discussed.
在体外测试了巨噬细胞激活作为豚鼠体内消灭恩氏利什曼原虫以及小鼠体内消灭热带利什曼原虫的效应机制。具有增强抗李斯特菌能力的活化豚鼠巨噬细胞,无论使用何种抗原,对细胞内恩氏利什曼原虫的存活均无影响。另一方面,活化的小鼠巨噬细胞在24 - 48小时内可消灭摄入的恩氏利什曼原虫,但在同一时间段内对热带利什曼原虫没有作用。有人提出,利什曼原虫在特定宿主体内的致病性取决于该寄生虫在宿主活化巨噬细胞中存活的能力。文中讨论了恩氏利什曼原虫在活化豚鼠巨噬细胞中逃避破坏的可能机制。
