Immunoinformatics 1st Class Quiz

Which molecular structure helps the immune system differentiate between self and non-self antigens?

• PAMPs

• TLRs

• MHC

• Cytokines

Which of the following cells is a part of innate immunity and directly kills virus-infected cells?

• NK cell

• Helper T cell

• Cytotoxic T cell

What is a key difference between innate and adaptive immunity?

• Adaptive immunity responds first

• Innate immunity requires memory cells

• Adaptive immunity is antigen-specific

• Innate immunity uses antibodies
