Viral ExoN regulates the rate of recombination in SARS-CoV-2


Viral ExoN regulates the rate of recombination in SARS-CoV-2
Researchers at Vanderbilt University Medical Center (VUMC) and the University of Texas Medical Branch (UTMB) at Galveston have discovered what may be the Achilles heel of the coronavirus, a finding that may help close the door on COVID-19 and possibly head off future pandemics.
The coronavirus is an RNA virus that has, in its enzymatic toolkit, a proofreading exoribonuclease, called nsp14-ExoN, which can correct errors in the RNA sequence that occur during replication, when copies of the virus are generated.
Using cutting-edge technologies and novel bioinformatics approaches, the researchers discovered that this ExoN also regulates the rate of recombination, the ability of the coronavirus to shuffle parts of its genome and even pull in genetic material from other viral strains while it replicates in order to gain evolutionary advantage. ....

Researchers identify genetic risk factors contributing to pneumonia susceptibility and severity


Researchers identify genetic risk factors contributing to pneumonia susceptibility and severity
Researchers at Vanderbilt University Medical Center and colleagues have identified genetic factors that increase the risk for developing pneumonia and its severe, life-threatening consequences.
Their findings, published recently in the
American Journal of Human Genetics, may aid efforts to identify patients with COVID-19 at greatest risk for pneumonia, and enable earlier interventions to prevent severe illness and death.
Despite the increasing availability of COVID-19 vaccines, it will take months to inoculate enough people to bring the pandemic under control, experts predict. In the meantime, thousands of Americans are hospitalized and die from COVID-19 each day. ....
