    In Sweden, scientists are looking to a farm animal to help them find a treatment or vaccine against the new coronavirus.
    扬州在线配资 瑞典的科学家希望一种家畜可以帮助他们找出针对新冠病毒的治疗办法或疫苗。

    Researchers from the Karolinska Institute, a medical university near Stockholm, are putting their hope in a 12-year-old alpaca from Germany. Alpacas belong to the camel family.

    The scientists started by recreating the so-called "spike" protein that permits the coronavirus to infect human cells. They then injected the spike protein into the alpaca, whose name is Tyson.

    The team is collecting blood samples to see whether the alpaca can develop antibodies against the spike protein. Extremely small antibodies, known as nanobodies, stick to the same part of the virus as human antibodies.

    In a statement to the press, the researchers called them "neutralizing antibodies." If you neutralize something harmful, you take away its ability to cause harm.
    在向股票论坛 界发表的声明中,研究人员称其为中和抗体。如果可以中和有害的东西,就能消除它造成伤害的能力。

    The head of the research team in Sweden is Gerald McInerney. He said the hope is that the neutralizing antibodies will be able to effectively block the virus protein -- and thereby the coronavirus -- from entering cells and spreading.

    The results could be used to develop drug treatments or possibly a vaccine for COVID-19, the disease caused by the coronavirus. While the scientific work is still at an early stage, McInerney said his team has seen evidence it could work in people.

    In a Reuters interview McInerney said, "In principle, all the evidence would suggest it will work very well in humans." He added however, that "it is a very complex system."

    McInerney noted that the coronavirus mutates "quite easily." So, researchers need to be prepared to develop several different kinds of antibodies.

    COVID-19 has killed more than 400,000 people around the world.

    McInerney explained that his team began its research back in January. At that time, they say they believed the coronavirus could become a serious pandemic. The researchers also knew it would take a long time to develop a vaccine, as well as drugs to slow the progression of the disease and save lives, he added.
    麦金纳尼解释说,他的团队从1月份开始研究。当时,他们认为新冠病毒可能会成为严重的大流行病。他还说,研究人员也早股票 ,开发疫苗以及减缓疾病进程并挽救性命会需要很长时间。

    But why use an alpaca?

    Studies have shown that alpacas and other members of the camel family are known to produce nanobodies. Nanobodies are easier for scientists to work with. Sharks have also been found to produce nanobodies. But sharks are not as easy to work with as alpacas.

    When will we have a vaccine?

    Scientific experts say it will likely take some time to develop a vaccine for COVID-19.

    The team in Sweden is moving on to the next step, which could involve testing with other animals, such as mice or hamsters. The scientists say they hope their results can be used as a model for future COVID-19 research.

    As for Tyson the alpaca, the researchers say his job is done.

    "Tyson is 12 years old, I believe, and he may be looking at retirement soon," McInerney told Reuters. "So, he'll live out his life on his farm back in Germany."
    扬州在线配资 麦金纳尼表示:“泰森12岁了,我认为它可能很快就要退休了。所以,他将回到德国的农场度过它的余生。”
