Antibodies found in shark could fight Covid-19 and its variants, new study finds


We are all aware that new variants of Covid-19 constantly pose new challenges for scientists, but according to a new study conducted at the University of Wisconsin in the United States, the antibody-like protein found in the immune system of sharks is not only useful in the prevention of the new coronavirus, but also its variants.

Shark antibody-like proteins neutralize the Covid-19 virus, according to the new study, adding that it can compete with its variants as well.

This protein is known as VNAR, which is one tenth the size of a human antibody. This protein may be small, the researchers say, but it can bind to the spike protein of the Covid-19 virus in unique ways. This can make it more able to prevent infection.

The coronavirus infects human cells via its spike protein. The researchers said that the use of this protein could lead to the development of an economical drug compared to human antibodies. However, it has not yet been tested on humans.

What are the experts saying?

Aaron LeBeau, associate professor in the Department of Pathology and Laboratory Medicine at the University of Wisconsin and researcher of this study, said: “The big challenge right now is to find new variants of the coronavirus that are emerging across the world. . We are preparing a new weapon from the shark’s VNAR, which can be used to fight this epidemic. “

He added that this tiny protein-like antibody can reach all over the place, even in places where human antibodies are unable to reach. Due to this ability, this protein may be more able to prevent infection.
