I'm Professor of Microbiology and Immunology at Columbia University in New York. I run a research lab where we study poliovirus, rhinovirus, and other RNA viruses. I also love teaching about viruses - check out virology.ws, microbe.tv, or iTunes University for some of my offerings. I want to be Earth's virology professor.

Molnupiravir, a SARS-CoV-2 antiviral drug, is mutagenic in cells

7 Comments / Basic virology / By

Molnupiravir might be the first highly effective antiviral drug given emergency use authorization for treatment of COVID-19. Should we be concerned about the results of a recent study which show that the drug is mutagenic in cells? Molnupiravir is an orally available pro-drug of the nucleoside analog N4-hydroxycytidine (NHC). The latter is a nucleoside analogue …

Gain of function to build therapeutically useful viral vectors

3 Comments / Basic virology / By

Another excellent example of gain of function research is modification of a viral vector to make it more useful for human gene therapy. Adenovirus associated virus (AAV) is the most commonly used vector for a variety of gene therapy applications, including gene replacement and gene editing. These small viruses, which comprise a single-stranded DNA genome …
