Immune Evasion

Question 1

Mimic host antigens

Answer 1

Endoparasites mimic host antigens to evade detection and modify host immune response to reduce their chances of destruction

Question 2

Antigenic variation

Answer 2

• antigenic variation in some parasites allows them to change between different antigens during the course of infection of a host.
• it may also allow reinfection of the same host with the new variation

Question 3

Integrating their genome

Answer 3

Some viruses escape immune surveillance by integrating their genome into host genomes, existing in an inactive state known as latency. The virus becomes active again when favourable conditions arise.
