Solution Preview

Antigenic mimicry is a mechanism of immune evasion that minimizes the adaptive immune response against the pathogen by making it appear less foreign. The most straightforward method employed to achieve this is where pathogens express a dominant antigen that is very similar to a host protein. Because the host ...
