【北大谢晓亮团队利用单细胞测序技术筛选新冠有效抗体】Chinese researchers have successfully identified multiple highly potent neutralizing antibodies against SARS-CoV-2, the virus that causes COVID-19, from convalescent plasma by high-throughput single-cell sequencing, according to a new study published in Cell on Sunday.
Generated by the human immune system, neutralizing antibodies can effectively prevent viruses from infecting cells. New results from animal studies showed that neutralizing antibodies provide a potential cure for COVID-19 as well as a means for short-term prevention, which marks a major milestone in the fight against the pandemic.
According to the research team, led by Sunney Xie, director of the Beijing Advanced Innovation Center for Genomics at Peking University, antibody drugs, as a kind of biologic, have been successfully applied to treat viruses like AIDS, Ebola, and MERS. However, it is often time-consuming to develop neutralizing antibodies suitable for clinical use, taking months or even years.
By using their expertise in single-cell genomics, the team collaborated with researchers at Beijing YouAn Hospital to collect blood samples from over 60 convalescent patients, among which 14 highly potent neutralizing antibodies were selected from 8,558 antigen-binding IgG1+ clonotypes.
Their animal experiments showed that the most potent antibody, BD-368-2, could provide strong therapeutic efficacy and prophylactic protection against SARS-CoV-2. According to the study, when the BD-368-2 antibody was injected into infected mice, the virus load was decreased by 2,400 times, and when uninfected mice were injected with BD-368-2, they were protected from being infected by the virus.
The potent neutralizing antibody could be used to develop drugs for both therapeutic intervention and prophylactic protection against SARS-CoV-2, Xie told Xinhua in an email interview.
He said clinical trials are underway, and the research team has strong confidence in finding a cure. "If the COVID-19 epidemic reappears in the winter, our neutralizing antibody might be available by that time," Xie said.

今天你回来了，不过哪怕距离再近，心也不会靠近了,个星期没有打卡了，今天一起打了吧waiting for love,just breathe,youan see the mirle.,不看开好像也没有什么办法，不知道第几个星期，打卡。,有一段时间没来了，一起打了吧。愿生活温柔待你,一眨眼的功夫但又漫长的像一个世纪,或许再也不会有联系或许再也不会见面虽然相隔距离只有十几公里虽然好想你祝福你过好每一天我一直都在这里等着你如果你需要的话,一年多没回来看了，时间冲淡了痛苦，但好像还没磨灭思念,头上不戴点绿，生活怎么过得去，呵呵，虽然算不上绿吧,突然想起你，或许不是突然，好像每一天都有你的身影。还是那样，快到中立之年了，还是不争气。很久没有这样绝望了，好像重新活一次，真的。,抽搐的疼,无论如何，希望你开心，够了不是么,生日快乐，这是认识你起，正好第十个年头沧海桑田，物是人非不变的唯有一如既往的祝福希望第二个十年，我还能对你说一声，生日快乐，足矣,又梦见你了很开心模糊的记得梦中你在嬉笑我是学文科的，你拿着物理还是数学卷子认真的写着，而我在旁边为了表现什么...有人说当梦见一个人的时候，说明她正在慢慢忘记你其实不管忘记还是记得也好，都不重要，人活在过去是一件痛苦的事情，我期望的从来都是你的开心^...^早啊，HR https://t.cn/R2WxK9G
