What is antigenic mimicry, and how does it allow pathogens to survive in the host?
A review of how various pathogens express antigens that mimic host antigens as a means of escaping the adaptive immune response. Includes specific examples and the implications for host immunology.
Describes antigenic mimicry and how some pathogens use this mechanism to avoid the immune system
