Mice immunized with either the predominantly vector-stage lipoprotein outer surface protein A (OspA) or the in vivo-expressed lipoprotein decorin binding protein A (DbpA) are protected against Borrelia burgdorferi challenge. DbpA-OspA combinations protected against 100-fold-higher challenge doses than did either single-antigen vaccine and conferred significant protection against heterologous B. burgdorferi, B. garinii, and B. afzelii isolates, suggesting that there is synergy between these two immunogens.
用主要为载体阶段的脂蛋白外表面蛋白A(OspA)或体内表达的脂蛋白核心蛋白聚糖结合蛋白A(DbpA)免疫的小鼠对伯氏疏螺旋体攻击具有抵抗力。与单一抗原疫苗相比,DbpA - OspA组合能抵抗高100倍的攻击剂量,并对异源的伯氏疏螺旋体、伽氏疏螺旋体和阿氏疏螺旋体分离株提供显著保护,这表明这两种免疫原之间存在协同作用。
