项目摘要
We showed that second dose PEGylated liposome is aggressively transported from marginal zone (MZ) into follicle in spleen when they are injected twice into the same rat with short interval1. We revealed that splenic MZ B cells capture and transport second dose liposomes into follicle in a time after second dose injection-dependent manner. The captured and then transported liposomes were finally taken up by follicular dendritic cell. We tried to apply this unique immune response to be a novel adjuvant system which enhances a specific antibody response against antigen encapsulated in second dose liposomes. Pre-immunization with low dose empty liposome, which triggers the transport of antigen-containing second dose liposomes into follicle, induced both anti-OVA IgM and anti-OVA IgG productions as OVA-containing liposomes, not free OVA, was intravenously injected as a second dose. The produced anti-OVA IgG contained IgG1, IgG2a and IgG2b subclasses. In addition, the high level of anti-OVA IgG lasted over 12 weeks after the immunization. These suggest that pre-stimulation with empty PEGylated liposomes could enhance the specific antibody response against antigen encapsulated in second dose liposomes. We conclude that our active transport methodology can be useful for a novel and alternative vaccine strategy to potentiate specific antibody response.
我们发现,在同一只大鼠体内短时间注射两次,第二次剂量的聚乙二醇化脂质体可以从脾脏边缘区(MZ)进入卵泡。我们发现脾脏mzb细胞在第二次注射后的一段时间内捕获并转运第二次剂量的脂质体到卵泡中。被捕获并转运的脂质体最终被滤泡树突状细胞吸收。我们试图将这种独特的免疫反应应用于一种新的佐剂系统,该系统可以增强针对第二次脂质体中封装的抗原的特异性抗体反应。预先免疫低剂量空脂质体,触发含有抗原的第二次脂质体转运进入卵泡,诱导抗OVA IgM和抗OVA IgG的产生,因为含有OVA的脂质体,而不是游离的OVA,被静脉注射作为第二次剂量。所得抗ova IgG含有IgG1、IgG2a和IgG2b亚类。免疫后抗ova IgG持续高水平达12周以上。这表明空聚乙二醇化脂质体的预刺激可以增强对第二次脂质体包封抗原的特异性抗体反应。我们的结论是,我们的主动转运方法可以用于一种新的和替代疫苗策略,以增强特异性抗体反应。
