A group of scientists from the United States managed to determine the real reason why many people were able to avoid infection with the new coronavirus, despite numerous contacts with virus carriers. This was reported by LIVE24 with reference to Science.

According to experts, having penetrated into a human cell, the virus begins to actively divide, with subsequent spread throughout the body, in search of the most susceptible cells, as reported by the Internet publication for girls and women from 14 to 35 years old Pannochka. net When a virus is detected and to destroy it, the immune system begins to turn on protective functions in the form of innate immune reactions (inflammation), due to which the adaptive immune system is activated. Further, in certain cells, the virus is recognized by T- and B-cells of the immune system.

The presence of a T- and B-cell reaction to a new coronavirus in people whose organisms have not previously encountered this virus, scientists explain by the fact that an earlier meeting of T- and B-cells with other coronaviruses allowed the body to “remember” the pathogen, and in a timely manner. “We believe these citizens' immune responses were influenced by earlier encounters with other viruses in the coronavirus family,” said experts Jennifer Hope and Linda Bradley, Sanford Burnham Prebis Medical Discovery Institute in Lo Hoya, California..
