Spike Protein
The spike protein is a part of the coronavirus that sticks out from its surface, like tiny keys. These 'keys' help the virus unlock and enter human cells by attaching to specific receptors, like the ACE2 receptor. Changes in the spike protein can affect how well the virus enters cells and how easily it can be recognized by the body's immune system.
