登革热病毒(DENV)是一种蚊媒黄病毒,每年造成5000万至1亿人感染,这突出表明需要一种安全有效的疫苗。在这项研究中,我们描述了使用两种不同的遗传互补方法生产假传染性DENV报告病毒颗粒(RVPs),包括创建以诱导方式释放报告病毒的细胞系。与西尼罗病毒(WNV)的研究相反,传染性DENV RVPs的产生与温度有关;与在较低温度下或用西尼罗河病毒进行的实验相比,在37°C下传染性登革热病毒RVPs的产量显著降低。这既反映了传染性DENV RVP释放率随时间的显著降低,也反映了传染性DENV RVP在37°C时的更快衰减。优化的生产方法使DENV RVPs的滴度适合研究DENV的进入、组装以及感染和接种个体的体液免疫反应分析。
Dengue virus (DENV) is a mosquito-borne flavivirus responsible for 50 to 100 million human infections each year, highlighting the need for a safe and effective vaccine. In this study, we describe the production of pseudoinfectious DENV reporter virus particles (RVPs) using two different genetic complementation approaches, including the creation of cell lines that release reporter viruses in an inducible fashion. In contrast to studies with West Nile virus (WNV), production of infectious DENV RVPs was temperature-dependent; the yield of infectious DENV RVPs at 37 °C is significantly reduced in comparison to experiments conducted at lower temperatures or with WNV. This reflects both a significant reduction in the rate of infectious DENV RVP release over time, and the more rapid decay of infectious DENV RVPs at 37 °C. Optimized production approaches allow the production of DENV RVPs with titers suitable for the study of DENV entry, assembly, and the analysis of the humoral immune response of infected and vaccinated individuals.
