Abstract

Various antibody therapeutics has been developed for the treatment and suppression of the 2019 outbreak of novel coronavirus(SARS-CoV-2)infection. A major limitation in the development of SARS-CoV-2 neutralizing antibodies is the occurrence and spread of escape variants that have mutations in the spike glycoprotein. The coronaviruses are carried by various wild animals, domestic animals, and pets, and there have been cases of Severe acute respiratory syndrome coronavirus and Middle East respiratory syndrome coronavirus transmission from animals to people, resulting in a large spread of infection in people. There is also a possibility that cross-species transmission of SARS-CoV-2 may occur in the future. Considering these factors, the development of antibody therapeutics with broad cross-reactivity against SARS-CoV-2 variants and other coronaviruses is required.Alternate :抄録2019年に発生した新型コロナウイルス(SARS-CoV-2)感染症の治療や発症抑制のためにさまざまな抗体医薬の開発が進められている。SARS-CoV-2中和抗体の開発で大きな障壁となるのが、スパイク糖タンパク質に変異をもつ変異株の発生と感染拡大である。またコロナウイルスは多くの野生動物や家畜、愛玩動物が保有しており、これまでにも重篤呼吸器症候群コロナウイルスや中東呼吸器症候群コロナウイルスが動物からヒトへ伝播して大きく感染が広がったケースがある。SARS-CoV-2についても動物が起源であると考えられており、今後も種を越えた伝播が発生する可能性が考えられる。これらを踏まえて、SARS-CoV-2変異株や類縁コロナウイルスに対する交差反応性に優れた抗体医薬の開発が求められる。
针对严重急性呼吸系统综合征冠状病毒2型的广泛反应性抗体疗法的开发
Various antibody therapeutics has been developed for the treatment and suppression of the 2019 outbreak of novel coronavirus(SARS-CoV-2)infection。A major limitation in the development of SARS-CoV-2neutralizing antibodies is the occurrence and spread of escape variants that have mutations in the spike glycoprotein。The coronaviruses are carried by various wild animals,domestic animals,and pets,and there have been cases of Severe acute respiratory syndrome coronavirusand Middle East respiratory syndrome coronavirustransmission from animals to people,resulting in a large spread of infection ople。There is also a possibility that cross-species transmission of SARS-CoV-2may occur in the future。Considering these factors,the development of antibody therapeutics with broad cross-reactivity against SARS-CoV-2variants and other coronaviruses is required。Alternate:为了治疗和抑制2019年发生的新型冠状病毒(SARS-COV-2)感染症,正在开发各种抗体医药。在SARS-CoV-2中和抗体的开发中,成为大障碍的是具有尖峰糖蛋白变异的变异株的发生和感染扩大。另外,冠状病毒由很多野生动物、家畜、玩赏动物拥有,至今为止也有严重呼吸综合征冠状病毒和中东呼吸综合征冠状病毒从动物传播到人类,感染扩大的情况。关于SARS-CoV-2,动物也被认为是起源,今后也有可能发生跨物种传播。在此基础上,需要开发对SARS-COV-2变异株和有关冠状病毒的交叉反应性优良的抗体医药。
