Schematics of the SARS-CoV-2 attack on human hACE2 and the subsequent immune system response. a, b RBD binding hACE2 without an interference. c RBD complexed with the antibody at receptor attachment site hence competing with hACE2. d RBD complexed with RBD at a site other than where receptor attaches resulting in the alteration of RBD structure and interruption of lock and key binding of RBD to hACE2
