List the various mechanisms viruses employ to evade the host immune system. A) Viruses use several different mechanisms to evade host immunity. They can mutate their outer surface proteins to evade neutralizing antibody, they can adopt a latent lifecycle, they can express proteins very close or identical in sequence to host proteins in order to elicit an autoimmune response, they can express soluble antigens to bind up circulating antibodies, they can interfere or inactive cytokine signaling, they may inactivate immune cells, and they can block the triggering of apoptosis. B) Viruses use
