项目摘要
Spontaneous transfer of protein from either influenza virus-infected or uninfected cells to dimyristoylphosphatidylcholine (DMPC) liposomes was examined. The amount of transferred protein of liposomes incubated with influenza virus-infected cells (I-lipo) was more than that of liposomes incubated with uninfected cells (U-lipo). The ratio of the amount of spontaneous transfer protein of I-lipo to that of U-lipo increased in proportion to the diameter of liposomes except for small unilamellar vesicles. The amounts of transferred protein of negative-charged liposomes composed of DMPC and stearic acid or dicetylphosohate were larger than that of neutral DMPC liposomes. There was a correlation between zeta potential of liposomes and the contents of transferred protein. Membrane fluidity, however, was appeared not to be responsible for the enhancing effect of negative charged liposomes on spontaneous protein transfer.Therefore, we concluded that membrane surface structure based on electrostatic condition of liposomes will play an important role in the spontaneous protein transfer from cell membrane to recipient vesicles.
研究了蛋白质从流感病毒感染或未感染的细胞自发转移到二肉豆蔻酰磷脂酰胆碱(DMPC)脂质体中的情况。脂质体与流感病毒感染细胞孵育后的蛋白质转移量(I-lipo)高于与未感染细胞孵育后的脂质体(U-lipo)。I-lipo与U-lipo的自发转运蛋白量之比与脂质体直径成比例增加,但小的单层囊泡除外。DMPC与硬脂酸或磷酸二鲸蜡酯组成的带负电荷脂质体的蛋白质转移量大于中性DMPC脂质体。脂质体的zeta电位与蛋白质的转移量之间存在一定的相关性。然而,膜流动性似乎不是负电荷脂质体增强自发蛋白质转移的原因,因此,我们认为基于静电条件的脂质体膜表面结构将在蛋白质从细胞膜自发转移到受体囊泡中起重要作用。
