Title: Understanding COVID-19 Biology to Design a Vaccine

Abstract: This multi-part case study introduces the reader to the SARS-CoV-2 virus, replication, and treatment. Additional worksheets introduce students to bioinformatics tools of 3-D protein visualization and BLAST searches.

Description:

The case presented here is written during the COVID-19 pandemic (Spring 2020) and uses this backdrop to introduce students to the initial stages of developing a vaccine against the SARS-CoV-2 virus, targeting its spike protein.  The viral protein binds to a specific human protein on human epithelial cells and this initiates the infection. The structure of the viral spike and human receptor protein interaction was  determined using cryo-electron microscopy by Yan et al (2020). Using the freely available molecular structural data and publicly available visualization software and bioinformatics tools and resources, the case leads students to examine the interaction of the viral spike (S) protein with the human epithelial cell ACE-2 protein, the site of viral attachment. The vaccine development discussed in this case is focused on blocking this interaction to stop infection.
