Mielenkiintoista nähdä, aletaanko tästä kysellä Faucilta kohta laajemminkin. Tuota gain-of-function tutkimusta potentiaalisilla pandemiapatogeeneilla on kritisoitu laajasti jo aikaisemmin. Kannattaa lukea koko artikkeli, alla ainoastaan sen ydinosa.
But just last year, the National Institute for Allergy and Infectious Diseases, the organization led by Dr. Fauci, funded scientists at the Wuhan Institute of Virology and other institutions for work on gain-of-function research on bat coronaviruses.
SARS-CoV-2 , the virus now causing a global pandemic, is believed to have originated in bats. U.S. intelligence, after originally asserting that the coronavirus had occurred naturally, conceded last month that the pandemic may have originated in a leak from the Wuhan lab. (At this point most scientists say it’s possible—but not likely—that the pandemic virus was engineered or manipulated.)
The NIH research consisted of two parts. The first part began in 2014 and involved surveillance of bat coronaviruses, and had a budget of $3.7 million. The program funded Shi Zheng-Li, a virologist at the Wuhan lab, and other researchers to investigate and catalogue bat coronaviruses in the wild. This part of the project was completed in 2019.
A second phase of the project, beginning that year, included additional surveillance work but also gain-of-function research for the purpose of understanding how bat coronaviruses could mutate to attack humans. The project was run by EcoHealth Alliance, a non-profit research group, under the direction of President Peter Daszak, an expert on disease ecology. NIH canceled the project just this past Friday, April 24th, Politico reported. Daszak did not immediately respond to Newsweek requests for comment.
The project proposal states: “We will use S protein sequence data, infectious clone technology, in vitro and in vivo infection experiments and analysis of receptor binding to test the hypothesis that % divergence thresholds in S protein sequences predict spillover potential.”
In layman’s terms, “spillover potential” refers to the ability of a virus to jump from animals to humans, which requires that the virus be able to attach to receptors in the cells of humans. SARS-CoV-2, for instance, is adept at binding to the ACE2 receptor in human lungs and other organs.
According to Richard Ebright, an infectious disease expert at Rutgers University, the project description refers to experiments that would enhance the ability of bat coronavirus to infect human cells and laboratory animals using techniques of genetic engineering. In the wake of the pandemic, that is a noteworthy detail.
Ebright, along with many other scientists, has been a vocal opponent of gain-of-function research because of the risk it presents of creating a pandemic through accidental release from a lab.
