2.4.5 immune evasion Flashcards
1
Q
how have parasites evolved
A
in ways that evade the immune system
2
Q
how do endoparasites evade detection
A
by mimicing host antigens and modifying host immune responses to reduce their chances of destruction
3
Q
what does antigenic variation allow
A
some parasites 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 variant
4
Q
how do some virusese escape immune surveillance
A
by integrating their genome into host genomes, existing in an inactive state known as latency
5
Q
what is latency
A
an inactive state
6
Q
when does a virus become active again after latency
A
when favourable conditions arise
