The biologist Barbara Gallavotti, regular guest of Giovanni Floris a Tuesday, on La7 explains the news on the coronavirus discoveries from Israeli researchers who have published a study on Nature. The question from which the research starts is: “Why is coronavirus a winner among infectious agents?”. So Gallavotti explains: “The coronavirus aims to take control of the cell, in particular its production system, and to force the cell to produce the coronavirus proteins which then assembled as in a Lego form the new infectious agent. “.
The cell, however, continues Gallavotti, “has security systems and chemically reacts by producing molecules that on the one hand hinder the virus inside it and on the other go outside the cell and warn the immune system. Like when in besieged cities. they came send messengers outside to call the allies to the rescue “. Unfortunately, however, explains the biologist,”this mechanism with the coronavirus does not respond to the best“.
What happens “is that when the cell realizes the presence of the invader tries to activate the genetic information aimed at countering the virus that is in its DNA and therefore in order for this emergency information to be brought to the production plant it must be transcribed in an Rna molecule and this should exit the nucleus and head towards the factory proteins “. In short, as in war,” there is a head to head between the RNA of the virus and that of the cell and the goal is to be the first to arrive at the cell’s operations center and put it at your service. Whoever manages to win has one more point. As in a game of chess “. Unfortunately, however, concludes Gallavotti,” it has been seen that in most cases the new coronavirus manages to checkmate to the cell and get to the protein factory first and that gives it a huge advantage. ”
