DISCOVERY OF SHAPE OF THE SARS-COV-2 GENOME AFTER INFECTION COULD INFORM NEW COVID-19 TREATMENTS
Scientists at the University of Cambridge, in collaboration with Justus-Liebig University, Germany, have uncovered how the genome of SARS-CoV-2 - the coronavirus that causes COVID-19 - uses genome origami to infect and replicate successfully inside host cells. This could inform the development of effective drugs that target specific parts of the virus genome, in the fight against COVID-19.
SARS-CoV-2 is one of many coronaviruses. All share the characteristic of having the largest single-stranded RNA genome in nature. This genome contains all the genetic code the virus needs to produce proteins, evade the immune system and replicate inside the human body. Much of that information is contained in the 3D structure adopted by this RNA genome when it infects cells.
The researchers say most current work to find drugs and vaccines for COVID-19 is focused on targeting the proteins of the virus. Because the shape of the RNA molecule is critical to its function, targeting the RNA directly with drugs to disrupt its structure ...
