Phenotyping Temperature-Sensitive Coronaviruses, Amani Eddins

Master's Theses

Coronaviruses (CoVs) can cause a range of symptoms; from a mild common cold to life threatening acute respiratory distress syndrome (ARDS) upon infection. These emerging viruses have the ability to be highly pathogenic and detrimental to the human population. Two prime examples of CoV emergence, SARS-CoV (Severe Acute Respiratory Syndrome) and MERS-CoV, (Middle Eastern Respiratory Syndrome), which exhibits the pandemic potential of emerging CoVs that gain human tropism. Given the increasing potential of an emerging CoV outbreak there is a state of urgency to develop vaccines that will help protect the human population against current and future circulating strains. The …

Cellular Determinants Of Coronavirus Entry Routes, James Thomas Earnest

Coronaviruses (CoVs) represent some of the greatest modern threats to global health. CoVs are zoonotic viruses that generally cause respiratory or enteric infections. The ability of CoVs to move between species and into human populations ensures that CoVs will remain important and dangerous pathogens. Therefore, understanding how CoVs infect different hosts is vital to human health.

CoVs are enveloped and must undergo fusion of viral and host membranes to initiate infection. Viral glycoproteins, called Spike (S) proteins, are responsible for host cell binding and carrying out the membrane fusion reaction. S proteins store energy in their folded, pre-fusion conformation that …
