The antitumor drug paclitaxel (Taxol) has been demonstrated to be a lipopolysaccharide mimetic in murine macrophages. In this study, the capacity of paclitaxel to activate macrophages to become microbicidal for Leishmania major was examined. Paclitaxel and gamma interferon synergized to kill intracellular L. major in Lpsn, but not Lpsd, macrophages by a nitric oxide (NO.)-dependent mechanism.
抗肿瘤药物紫杉醇(泰素)已被证明在小鼠巨噬细胞中具有脂多糖模拟物的作用。在本研究中,检测了紫杉醇激活巨噬细胞对杜氏利什曼原虫产生杀菌作用的能力。紫杉醇和γ干扰素协同作用,通过一氧化氮(NO.)依赖性机制杀死Lpsn巨噬细胞内的杜氏利什曼原虫,但对Lpsd巨噬细胞无效。
