摘要(Abstract):

为了鉴定表达爱泼斯坦-巴尔病毒(Epstein-Barr virus,EBV)gH/gL保护性抗原的腺病毒载体疫苗在BALB/c小鼠中的T细胞表位,本研究使用表达gH/gL蛋白的腺病毒载体EBV疫苗免疫BALB/c小鼠,利用IEDB Analysis Resource软件对序列进行亲和力预测,设计合成EBV gH基因和gL基因的肽库,并将其混合成肽池,取免疫后的小鼠脾细胞进行IFN-γ ELISPOT检测,通过肽池和单肽两轮筛选检测具有阳性反应的多肽片段,确定优势反应肽。结果显示筛选出gH基因5条特异性优势肽,其中序列为LRGPFSYPSLTSAQS的单肽反应最强;gL基因4条特异性优势肽,其中序列为ASLNSPKNGSNQLVI的单肽反应最强。本研究使用IFN-γ ELISPOT法筛选和确定了9条EBV gH抗原特异性和gL抗原特异性优势T细胞表位,为EBV免疫学与疫苗研究提供了参考。
