The new coronavirus has caused millions of deaths worldwide, but the fact remains that most patients have mild or moderate severity.
Medical experts are constantly working on why the severity of the corona virus is mild or moderate in most people.
It has now been discovered that corona viruses, which cause the common cold, train the immune system to identify new corona viruses.
Research published in the medical journal Science found that immune cells, called T cells, were able to identify corona viruses that cause the common cold and that they could detect specific sites of new corona viruses, including spike proteins. Also identify.
This 'memory' of the immune system may explain why the severity of code 19 is mild or moderate in most people.
The researchers stressed that this is currently speculation and further research is needed to confirm it, as it is not yet known to what extent T cells play a role in the fight against code 19.
It should be noted that T cells are just a part of the innumerable molecules and cells that make up our immune system.
"We can now prove that the memory of T cells against the corona viruses that cause the common cold helps us to identify new corona viruses," said experts involved in the study by the La Jolla Institute in the United States.
He said that it is possible that the movement of the immune system gives different types of protection against code 19 to most people.
According to him, strong T cells response or better response of T cells may give you the opportunity to have more fast and strong reaction.
Earlier research reports showed that 50% of people who did not become infected with COD 19 had T cells in their bodies that could identify the new corona virus.
This ability has been observed in people around the world, and researchers believe that this immunity or immunity may be the result of being affected by other corona viruses in the past, especially the corona viruses that cause the common cold.
In the new study, researchers analyzed blood samples collected between 2015 and 2018, meaning the samples were from before the corona virus was detected.
The samples detected T cells that reacted to more than 100 specific sites of the new corona virus.
The researchers said that the results showed strong molecular evidence that the memory of T cells could see similar genetic sequences of common corona viruses and new corona viruses.
Researchers point out that these T cells are different from the antibodies that inactivate the virus, and that the immune system is another weapon used to prevent germs from infecting cells.
Antibodies to the common cold virus are limited to these viruses and do not react against the new corona virus.
