中东呼吸综合征冠状病毒(MERS-CoV)引起的疾病疫情仍在中东持续爆发。自 2012 年 9 月首次报告以来,已有 1700 多人被感染。尽管付出了巨大努力,但针对 MERS-CoV 的许可疫苗或治疗药物仍然无法获得。 MERS-CoV 刺突 (S) 蛋白是一种重要的病毒抗原,已知可介导宿主-受体结合和病毒进入,并在感染过程中诱导人类强烈的体液和细胞介导的反应。在这篇综述中,我们强调了 S 蛋白在 MERS-CoV 生命周期中的重要性,总结了基于 S 蛋白的疫苗和治疗药物开发的最新进展,并讨论了可探索的策略,以开发针对 MERS-CoV 的新医学对策。迄今为止,尚未获得获得许可的针对中东呼吸综合征冠状病毒的疫苗或治疗方法。 S蛋白在病毒进入过程中发挥着关键作用,因此是疫苗和抗病毒药物开发的理想靶点。表达 S 蛋白的 DNA 疫苗值得进一步开发以用于潜在的人类应用。在临床试验之前,需要在 NHP 中评估针对 S 蛋白的 nAb 和肽。
The disease outbreak caused by Middle East respiratory syndrome coronavirus (MERS-CoV) is still ongoing in the Middle East. Over 1700 people have been infected since it was first reported in September 2012. Despite great efforts, licensed vaccines or therapeutics against MERS-CoV remain unavailable. The MERS-CoV spike (S) protein is an important viral antigen known to mediate host-receptor binding and virus entry, as well as induce robust humoral and cell-mediated responses in humans during infection. In this review, we highlight the importance of the S protein in the MERS-CoV life cycle, summarize recent advances in the development of vaccines and therapeutics based on the S protein, and discuss strategies that can be explored to develop new medical countermeasures against MERS-CoV. A licensed vaccine or therapeutic against MERS-CoV remains unavailable to date. The S protein plays a pivotal role for virus entry and thus is an ideal target for vaccine and antiviral development. DNA vaccines expressing the S protein merit further development for potential human application. nAbs and peptides targeting the S protein needs to be evaluated in NHPs before clinical trials.
