FRONT CELL INFECT MI:预防登革热病毒感染的新疫苗

2017-05-31 MedSci MedSci原创

登革热是全球传播最快的蚊媒疾病之一,已成为严重的公共卫生问题。登革热病毒(DV)是登革热的致病病原体。目前,登革热仍没有具体的治疗方法。因此,疫苗将是降低发病率和死亡率的有效对策。虽然嵌合型黄热病登革热四价疫苗已在一些国家得到批准,但仍然需要开发更安全,更有效,成本更低的疫苗。

近日,国际杂志Frontiers in Cellular and Infection Microbiology上在线发表一项关于预防登革热病毒感染的新疫苗的研究。

登革热是全球传播最快的蚊媒疾病之一,已成为严重的公共卫生问题。登革热病毒(DV)是登革热的致病病原体。目前,登革热仍没有具体的治疗方法。因此,疫苗将是降低发病率和死亡率的有效对策。虽然嵌合型黄热病登革热四价疫苗已在一些国家得到批准,但仍然需要开发更安全,更有效,成本更低的疫苗。

在本研究中,研究人员通过肌内注射或电穿孔将表达DV1prME蛋白的DNA疫苗候选pVAX1-D1ME接种在BALB / c小鼠中,并评价其免疫原性和保护性。与传统的肌内注射相比,通过三次免疫电穿孔用50μgpVAX1-D1ME给药引起持续性体液和细胞免疫应答,并有效保护小鼠免受致死性DV1攻击。此外,通过电穿孔用pVAX1-D1MEpVAX1-D2ME组成的二价疫苗进行免疫,产生平衡的IgG应答和中和抗DV1DV2的抗体,并且可以保护小鼠免受DV1DV2的致死性攻击。

这项研究揭示了开发登革热四价DNA疫苗的新亮点。
