Questions and Answers

What happens when naive lymphocytes recognize microbial antigens and receive additional signals induced by microbes?

  • They proliferate and differentiate into effector cells and memory cells (correct)
  • They lose their antigen-specific receptors
  • They undergo apoptosis
  • They remain in the generative lymphoid organs

    • Where do naive lymphocytes temporarily reside if they are not activated by antigen?

  • Tertiary lymphoid organs
  • Bone marrow
  • Generative lymphoid organs
  • Secondary lymphoid organs (correct)

    • How do naive lymphocytes die if they are not activated by antigen?

  • Apoptosis (correct)
  • Necrosis
  • Phagocytosis
  • Autolysis
