Why Some People Are Protected Against Covid-19? Study Reveals

Covid-19 News-A study about COVID-19 reveals some surprising information. In some people, the COVID infection is eliminated immediately after entering the nasal chamber.

In which the immune cells present in that person’s body work very fast. Before the virus enters the cells and infects them, it is eliminated, due to which the person is not affected by the infection.

A special gene also plays a role behind this, which is very active in some people.Nature was published in the science journal called Study Gives new information about Covid infection. Some people do not get infected even after exposure to the Covid virus.

Researchers conducted an experiment in which volunteers were exposed to the pre-alpha strain of SARS-CoV-2. The experiment found that the immune response in the nasal tissue of those who resisted infection was very fast.

This response is activated by MAIT cells, which also include white blood cells. They destroy the virus before it can settle in the nose.

These people had higher expression of a gene called HLA-DQA2. This research shows how our immune system protects us from infections, which cannot be possible through any other external means.

This research will have a major impact on the next generation of methods to prevent SARS-CoV-2. Apart from this, this research can also contribute to the treatments invented to prevent other epidemics.

This response of the immune system can also be copied in the vaccines and treatments used for such epidemics. So that in future more effective treatments can be discovered for such diseases. covid-19 news.
