为建立并获取更有效的乙肝疫苗,本实验通过将所构建的HBVRNA复制子疫苗和DNA疫苗分别免疫小鼠,检测细胞免疫与体液免疫的效果。结果表明,以pSFV为基础构建的疫苗载体免疫小鼠后采集的血清中抗体效价不随免疫剂量的增加而提高,在较低剂量免疫的时候,RNA复制子疫苗所产生的抗体效价优于DNA疫苗。并且RNA复制子疫苗在以较低剂量免疫后脾细胞CTL活性高于DNA疫苗。本研究证明HBVRNA疫苗比DNA疫苗表达效果更好,安全性更高,更具有应用前景。
為建立併穫取更有效的乙肝疫苗,本實驗通過將所構建的HBVRNA複製子疫苗和DNA疫苗分彆免疫小鼠,檢測細胞免疫與體液免疫的效果。結果錶明,以pSFV為基礎構建的疫苗載體免疫小鼠後採集的血清中抗體效價不隨免疫劑量的增加而提高,在較低劑量免疫的時候,RNA複製子疫苗所產生的抗體效價優于DNA疫苗。併且RNA複製子疫苗在以較低劑量免疫後脾細胞CTL活性高于DNA疫苗。本研究證明HBVRNA疫苗比DNA疫苗錶達效果更好,安全性更高,更具有應用前景。

To establish and obtain a more effective hepatitis B vaccine (HBV), mice cellular and humoral immunity were detected and compared after being immunized by the RNA replicon vaccines and DNA vaccines of HBV which were constructed by our lab. The results showed that RNA replicon vaccines gained higher immune antibody titer, and higher CTL activity of spleen cells than that of DNA vaccines at low-dose, but not dose dependent. It was concluded that HBV RNA vaccines are much safer and gained higher expression efficiency than the DNA vaccines, thus RNA vaccines of HBV are more prospective for the gene therapy of HBV.
