title: Characterization of biosurfactant-containing liposomes and their efficiency for gene transfection.
abstract: Recently we showed significance of biosurfactants in the field of non-viral vectors for gene transfection. There, a biosurfactant, mannosylerythritol lipid A (MEL-A), especially increased the efficiency of gene transfection mediated with cationic liposomes. However, the molecular mechanism has not been well-understood yet. Here, through the examination of the ability of cationic liposomes containing an MEL (MEL-A, MEL-B or MEL-C) for important transfectional processes of the DNA capsulation and the membrane fusion with anionic liposomes, we found that MEL-A-containing liposomes increased both processes, but that MEL-B and MEL-C-containing liposomes just increased either of them. The results indicated that these kinds of the physicochemical properties in MEL-A-containing liposomes are able to increase the efficiency of liposome-mediated gene transfection.
