Questions and Answers

Which type of pathogens do MHC class I molecules present peptide antigens derived from?

  • Pathogens that affect the immune system
  • Pathogens that replicate inside the cell, such as viruses (correct)
  • Pathogens that infect the bloodstream
  • Pathogens that are present outside the cell

    • From where do MHC class II molecules present peptides?

  • Pathogens that replicate inside the cell
