Sidebar: How Coronaviruses infect cells

Published March 24 by Lasya Vankayala

Let’s think of a virus as a highly trained secret agent trying to break into a secure fortress- your cell. This article explains how the virus uses secret agent tactics to get into host cells.

Coronaviruses in particular use a spike protein to attach to a receptor protein on the surface of the cell. This spike protein acts as a universal key skeleton key to get our secret agent virus into the cell.

Learn how a virus is a lot like a secret agent and the arsenal of tools that it uses.

Sidebar: On Mutation

Published March 20 by Lasya Vankayala

This article is a refresher on DNA, RNA and mutation.

DNA is the instruction manual for life and how human cells use DNA as their genetic material. When a human cell makes a copy of itself or is tricked into making a copy of a virus, the genetic material (DNA or RNA) has to be copied. This copying mechanism isn’t perfect and sometimes mistakes can happen. These mistakes are called mutations.

Understand mutations and how coronaviruses can avoid them.

Scripps Research Institute: A SARS Antibody May Also Target SARS-CoV-2 Spike Proteins

Published May 15 by Annoj Thavalingam, reviewed by Dr. Zachary Benet

The outside of coronaviruses are studded with spikes that are important for infecting human cells. Antibodies are immune molecules designed to bind a very specific bacterium or virus, targeting it for removal.

An antibody previously found to bind the spikes of the 2003 SARS coronavirus can also bind the spikes of the novel SARS-CoV-2 virus.

Further research into cross-reactive antibodies like this one may one day lead to antibody therapies that can target multiple types of coronaviruses.

We explain how the scientists discovered this antibody and what this means for future COVID-19 treatments.

The NAbs and DAbs Guide to Understanding How Antibodies Can Enhance Coronavirus Entry Into our Cells

Published May 13 by Manolya Sag, reviewed by Dr. Sebastian Lequime

This team of researchers investigated a phenomenon known as antibody-dependent enhancement (ADE) of viral entry.

They looked at ADE for the coronaviruses SARS-CoV (responsible for the 2003 SARS outbreak) and MERS-CoV. They found that neutralizing antibodies that would have stopped SARS-CoV (the virus responsible for the 2003 SARS outbreak) could potentially lead to a worse infection in the case of a close relative virus.

Find out more about what ADE is, and how this information may factor into future antibody treatments for SARS-CoV-2.
