carwash/jump, 一块回一下,你们要是 看第一帖和题目,这是 一个 open discussion 的楼 ;
除了致病性,你们都 提到 转染性,你们的意思大概是 synergistic effect,如果这个存在,那是有 gain function 嫌疑;
我早早对gain function 的反对在旧mit 就是挂号的; 对这个研究,我的基本态度和这两位差不多;
“不过,这项研究已招致其他科学家的批评。以色列政府首席科学家夏皮洛 (Shmuel Shapira)说:“这是在玩火,这应该全面禁止。”英国东英吉利大学微生物学教授利弗莫尔则说:“鉴于新冠病毒大流行很可能起源于武汉实验室操纵的冠状病毒逃脱,这些实验似乎非常不明智。”
我刚才还找到了,BU 的正式回应,分享一下:

摘:
The study set out to examine the spike proteins on the SARS-CoV-2 Omicron variant (BA.1). Researchers were interested in comparing the variant with the original virus strain, known as the Washington strain. They wanted to find out if the virus was truly less virulent, says Corley, “simply because it wasn’t infecting the same cells as the initial strain.” They were “interested in what part of the virus dictates how serious of a disease a person will get.”
But Corley says the news reports pulled one line from the paper’s abstract out of context, with the Daily Mail suggesting in its headline that the researchers had created a “deadly Covid strain with an 80 percent kill rate.” The newspaper went on to make a series of other misleading claims, including that the study was “gain of function research,” alleging researchers set out to make a more deadly virus.
Not true, says Corley. And the University’s statement strongly denied it.
“We want to address the false and inaccurate reporting about Boston University COVID-19 research, which appeared today in the Daily Mail,” said the BU statement. “First, this research is not gain-of-function research, meaning it did not amplify the Washington state SARS-CoV-2 virus strain or make it more dangerous. In fact, this research made the virus replicate less dangerous.”
Corley says the line pulled out of context actually had nothing to do with the virus’ effect on humans. The study began in a tissue culture, then moved to an animal model.
“The animal model that was used was a particular type of mouse that is highly susceptible, and 80 to 100 percent of the infected mice succumb to disease from the original strain, the so-called Washington strain,” says Corley. “Whereas Omicron causes a very mild disease in these animals.”
That 80 percent number is what the media reports latched onto, misrepresenting the study and its goals.
“This was a statement taken out of context for the purposes of sensationalism,” says Corley, “and it totally misrepresents not only the findings, but [also] the purpose of the study.”
In fact, according to BU’s statement, “this research mirrors and reinforces the findings of other, similar research performed by other organizations, including the FDA.” That’s supported by one of the lead researchers on the study, Mohsan Saeed, a NEIDL investigator.
“Consistent with studies published by others, this work shows that it is not the spike protein that drives Omicron pathogenicity, but instead other viral proteins,” says Saeed, a BU Chobanian & Avedisian School of Medicine assistant professor of biochemistry. “Determination of those proteins will lead to better diagnostics and disease management strategies.”
