流感病毒神经氨酸酶(NA)主要参与从感染细胞释放子代病毒,这是病毒复制的关键作用。与免疫优势型血凝素相比,NA亚型较少,NA抗原漂移速度较慢,免疫选择压力较小。此外,NA抑制抗体阻止病毒的排出,从而阻止病毒的传播。在人类和各种动物模型中,抗na免疫可以减轻疾病严重程度,减少病毒脱落,降低病毒肺滴度。因此,各方一致努力研究在未来的疫苗配方中加入免疫原性形式的NA作为疫苗抗原的可能性。在这篇综述中,我们讨论了基于na的免疫,并描述了几种具有广泛保护作用的人na特异性单克隆抗体(mab)。我们还回顾了正在临床前模型中研究NA抗原的疫苗平台及其在下一代流感病毒疫苗中的潜在用途。本文提出的证据支持在未来的流感病毒疫苗中纳入免疫原性NA。
The influenza virus neuraminidase (NA) is primarily involved in the release of progeny viruses from infected cells—a critical role for virus replication. Compared to the immuno-dominant hemagglutinin, there are fewer NA subtypes, and NA experiences a slower rate of antigenic drift and reduced immune selection pressure. Furthermore, NA inhibiting antibodies prevent viral egress, thus preventing viral spread. Anti-NA immunity can lessen disease severity, reduce viral shedding, and decrease viral lung titers in humans and various animal models. As a result, there has been a concerted effort to investigate the possibilities of incorporating immunogenic forms of NA as a vaccine antigen in future vaccine formulations. In this review, we discuss NA-based immunity and describe several human NA-specific monoclonal antibodies (mAbs) that have a broad range of protection. We also review vaccine platforms that are investigating NA antigens in pre-clinical models and their potential use for next-generation influenza virus vaccines. The evidence presented here supports the inclusion of immunogenic NA in future influenza virus vaccines.
