Studies have shown that the virus that causes coronavirus infection-19 (corona19) has been modified to make it easier to penetrate human cells.

According to CNN broadcast on the 14th of local time, a research team at the Scripps Research Institute in Florida, USA, discovered that the virus mutation affects'spike protein', an external structure used for cell penetration.

If this finding is confirmed, CNN estimates that the virus mutation will be the first to demonstrate that it is important for the Corona19 pandemic.

It is also possible to explain why the United States has suffered more severely with Corona 19 than any other country.

"The virus that has undergone this mutation is much more contagious than the virus without mutation in the cell culture system," said Choi Hye-ryun, the virologist who led the study.

Spike protein refers to the sticky, protruding structure that viruses need to penetrate human cells.

The team showed through a series of experiments that a mutation called D614G made more protrusions and made them more stable.

The study was reported to have been conducted in three different experiments.

This research is waiting for review by other experts in the journal Life Sciences, Buyer Rxiv.

Researchers at the Los Alamos National Institute in the United States announced in April that the D614G mutation became the most common strain spread across Europe and the United States, and that it was an "urgent concern" to Bio Rxiv.

At that time, further research was needed to determine whether this variation and the US-European corona19 widespread coincidence were coincidental, but CNN evaluated that the study at the Scripps lab was advanced in that it analyzed the correlation between the two. .
