Countries; Frequently asked questions; Procurement; Regions. [2] The individual S proteins are arranged in groups of three on the outer membrane, giving the virus a distinctive crown or ‘corona’-like appearance that is typical of coronaviruses. The study, done on a mild-mannered relative of the virus that causes COVID-19, paves the way for seeing more clearly how spike proteins initiate infections, with an eye to preventing and treating them.. Coronaviruses like the one that causes COVID-19 are studded with protein “spikes” that bind with receptors on the cells of their victims ­– the first step in infection. Cell membranes are just a few nanometers thick but are essential for life. The outbreak of severe acute respiratory syndrome (SARS) in 2003 and, more recently, Middle-East respiratory syndrome (MERS) has demonstrated the lethality of CoVs when they cross the species barrier and infect humans. Electron microscopy techniques showed that the coronavirus spikes maintained the desired shape in the vaccine, which should help stimulate an appropriate immune response.
