A new study further elucidates the role of spike proteins in COVID-19. Authors: Steven Novella  May 5, 2021 A recent study looks at the effects of the SARS-CoV-2 spike proteins, showing that they can cause some of the harm of COVID-19 by themselves. This is an important advance in our understanding of the disease and hopefully […]

13 ways that the SARS-CoV-2 spike protein causes damage

Posted on | Posted on John Murphy | Leave a Comment on 13 ways that the SARS-CoV-2 spike protein causes damage

Authors: Posted on January 13, 2022 by Jesse Santiano, M.D. The SARS-CoV-2 virus has four structural proteins. The spike, membrane, envelop, and nucleocapsid proteins. The spike protein protrudes from the middle of the coronavirus and attaches to the ACE2 receptor of cells to start the process of cell entry, replication, and infection. The two major parts of the […]
