为了预防由新型冠状病毒SARS-CoV-2引起的2019冠状病毒病,有效的疫苗至关重要。本文中,已经合成了来自SARS-CoV-2的刺突蛋白的几个潜在的肽表位,并与交叉反应材料(CRM 197)共价连接。用所得缀合物免疫小鼠诱导针对刺突蛋白的高滴度IgG抗体。重要的是,免疫后血清有效地中和SARS-CoV-2假病毒,表明鉴定的表位是保护性的,并且这些缀合物是抗SARS-CoV-2疫苗开发的有希望的线索。
For prevention of the coronavirus disease 2019 caused by the novel coronavirus SARS-CoV-2, an effective vaccine is critical. Herein, several potential peptide epitopes from the spike protein of SARS-CoV-2 have been synthesized and covalently linked with the cross-reactive material (CRM197). Immunization of mice with the resulting conjugates induced high titers of IgG antibodies against the spike protein. Importantly, the post-immune sera effectively neutralized SARS-CoV-2 pseudovirus, suggesting the epitopes identified are protective, and these conjugates are promising leads for anti-SARS-CoV-2 vaccine development.
