呼吸道合胞病毒(RSV)是所有年龄段人群呼吸道感染的重要原因,也是婴儿住院的主要原因。虽然市售单克隆抗体可用于有严重疾病风险的新生儿的被动预防,但没有可用的疫苗来预防RSV。中和活性的测量将是疫苗评价的一个关键终点。抗RSV中和抗体的评估仅限于传统的斑块减少,这是耗时的,固有的操作员依赖性和高度可变的。在这里,我们描述了一种基于流式细胞术的rsv特异性中和试验,该试验比传统方法更快,灵敏度高,重复性高。
Respiratory syncytial virus (RSV) is an important cause of respiratory infection in people of all ages, and is the leading cause of hospitalization in infants. Although commercially available monoclonal antibody is available for passive prophylaxis of neonates at risk of severe disease, there is no available vaccine to prevent RSV. Measurement of neutralizing activity will be a key endpoint for vaccine evaluation. Assessment of neutralizing antibody against RSV has been limited to traditional plaque reduction, which is time consuming and inherently operator dependent and highly variable. Here, we describe a flow cytometry-based RSV-specific neutralization assay which is more rapid than traditional methods, highly sensitive and highly reproducible.
