Study Shows How Covid Virus Shields Itself In Replication

New Delhi: US researchers have identified a mechanism that SARS-CoV-2 -- the virus that causes Covid-19 -- uses to protect itself inside the body as it works to replicate and infect more cells.

Without this protective mechanism, viral infection is dramatically reduced, said the team from the Texas Biomedical Research Institute and the University of Chicago.

The finding, published in the journal Nature Communications, not only provides a potential target for new Covid therapies but also offers insights that could inform future vaccine and antiviral development.

The study builds on earlier work from Texas Biomed that identified ORF3a, a type of viral protein most important for the virus's pathogenicity, or ability to cause disease.
