【摘要】:目的:觀察乙型肝炎病毒表面抗原中蛋白(MHBs)核酸疫苗在中國獼猴體內的體液和細胞免疫應答。方法:實驗用中國獼猴實驗組、對照組各2只,分別在第0、8、16、24、48周肌肉注射法接種核酸疫苗(pSW3891/MHBs)或對照載體(pSW3891)。ELISA法檢測中國獼猴血清抗-HBs,CFSE-PI染色FCM(流式細胞術)法測定中國獼猴外周血淋巴細胞HBsAg特異性增殖反應。結果:實驗組中國獼猴血清抗-HBs滴度在72周達到最高峰,最高滴度分別為1∶6400和1∶12800,對照組抗-HBs滴度始終保持在1∶50。實驗組中國獼猴外周血淋巴細胞HBsAg特異性增殖反應明顯增強,細胞分裂指數(shù)分別
[Abstract]:Aim: to observe the humoral and cellular immune responses of hepatitis B virus surface antigen protein (MHBs) nucleic acid vaccine in Chinese rhesus monkeys. Methods: the serum anti-HBs, of Chinese rhesus monkeys was detected by intramuscular injection of nucleic acid vaccine (pSW3891/MHBs) or control vector (pSW3891). ELISA) at 0, 8, 16, 24 and 48 weeks after intramuscular injection of nucleic acid vaccine (HBs,) or control vector (pSW3891). ELISA). The specific proliferation of HBsAg in peripheral blood lymphocytes of Chinese rhesus monkeys was measured by CFSE-PI staining FCM (flow cytometry). Results: the serum anti-HBs titer of Chinese rhesus monkeys in the experimental group reached the peak at 72 weeks, and the highest titers were 1 鈮,
