脂质体(Liposomes)是由人工制成具有单层或多层单位膜样结构的脂质小囊(Lipid Vesicles).对脂质体的研究始于六十年代,现已形成一个新的科学领域.脂质体除了作为模型膜系统及药物传送系统越来越引起重视外,近几年来已在免疫学的研究中得到广泛应用,其中包括:1)作为抗原载体和免疫佐剂;2)作为淋巴因子的载体;3)作为体外免疫诱导的工具;4)作为免疫反应的靶子;5)用以阐明补体激活的机制;6)用于研究抗体导向的"趋 Liposomes are made of artificial Lipid Vesicles with single or multiple unit membranous structures.Studies on liposomes began in the 1960s and now form a new science In recent years, liposomes have been widely used in immunology research, including 1) as an antigen carrier and immune adjuvant; 2) liposomes, As a carrier for lymphokines; 3) as a tool for in vitro immune induction; 4) as a target for an immune response; 5) for elucidation of the mechanism of complement activation; 6) for the study of antibody-
