Intranasal administration of neutralizing IgA increases SARS-CoV-2 infection in a hamster model

Infectivity of SARS-CoV-2 is associated with high viral loads in the upper respiratory tract. Alpha and gamma immunoglobulins (IgA and IgG) both neutralize viral infections, with IgA significant in mucosal immunity and IgG predominantly affecting blood. Most studies focus on IgG in SARS-CoV-2 infection, but the role of IgA is less understood. To enter host […]

N-terminomics of SARS-CoV-2

A better understanding of the interactions between SARS-CoV-2 and the host cells it infects could lead to new approaches to treat or prevent infections. Proteolysis is essential to the SARS-CoV-2 life cycle; two viral polyproteins must be cleaved to generate components of the viral replication/transcription complex. The polyproteins are snipped apart by two viral proteases, […]

What is Western Blotting?

Your common Western blotting questions, answered Western blotting is a widely used analytical technique that can identify one or more specific proteins in a complex mixture of proteins. It is a powerful tool that provides information about the presence, size, and under the right conditions, even the amount of a protein. Though commonly used and […]

Investigating S-acylation of the SARS-Cov-2 Spike Protein Leads to New Insights into Viral Infectivity

A better understanding of coronavirus biology can enable development of new antivirals to help stop COVID-19 and prevent future pandemics. In recent work, Puthenveetil et al. characterized S-acylation of the Spike (S) protein of SARS-CoV-2. This post-translational modification is known to be important to the viral replication cycle of other viruses across multiple virus families […]
