This disclosure describes structural elements that enhance fusogenicity of lipids and lipid assemblies (e.g. liposomes) with biological membranes, in particular cell membranes, and use of such structures. The elements are pH sensitive in terms of charge and hydrophilicity and undergo a polar—apolar transition when exposed to low pH.
本公开描述了增强脂质和脂质组装物(例如脂质体)与
生物膜,特别是细胞膜融合性的结构元素,以及这些结构的应用。这些元素在电荷和亲
水性方面对pH敏感,并在暴露于低pH时经历极性-非极性转变。
