【Abstract】 Liposomes are artificial membrane vesicles which can be used as either passive or active targeted drug carrier systems. In polypeptide and protein drug- delivery systems, liposomes have some unique therapeutic advantages, such as the ability to deliver drugs to specific sites, to protect polypeptide and protein from degradation in the digestion track , and to increase the systemic circulation time of the drug when PEGylated liposomes are used. In this article, the latest developments including the novel methods of liposomal preparation, new forms of liposomes and the progress in industrialized production of liposomes, are summarized. In addition, some problems existing in this drug-delivery system are put forward and some possible developments of polypeptide and protein liposomes in the future is prospected. Although liposomes have been made much progress in biological area, there still exist many tough problems having not been settled.更多还原
