II. building the viral shell from host proteins

I. Frequent mutations in genes for surface proteins can help a virus evade the immune system by altering its antigens and thus avoiding recognition by antibodies.II. Building the viral shell from host proteins can help the virus avoid detection by the immune system because the viral shell will mimic host cells, making it harder for the immune system to recognize the virus as foreign.IV. Infecting and killing helper T cells can impair the adaptive immune response by directly targeting and diminishing the population of cells that play a crucial role in activating other immune cells.
