ROCKVILLE, MD – The virus that causes COVID-19, called SARS-CoV-2, uses its spike protein in order to stick to and infect our cells. The final step for the virus to enter our cells is for part of its spike protein to act like a twist tie, forcing the host cell’s outer membrane to fuse with the virus. Kailu Yang, in the lab of Axel Brunger, colleagues at Stanford University, and collaborators at University of California Berkely, Harvard Medical School, and University of Finland have generated a molecule based on the twisted part of the spike protein (called HR2), which sticks itself onto the virus and prevents the spike protein from twisting.
