Questions and Answers

Why are dendritic cells named so?

  • Being lymphoid in cell lineage
  • Due to their involvement in phagocytosis
  • Secreting inflammatory cytokines
  • Presence of long cytoplasmic projections or dendrites (correct)

    • What is the main function of dendritic cells in the immune system?

  • Secreting protective response against viruses
  • Phagocytosis of pathogens
  • Producing inflammatory cytokines
  • Activating T-cells by presenting antigens (correct)

    • What is cytotoxicity in the context of the immune system?

  • The ability to cause death of a target cell (correct)
  • The process of presenting antigens to T-cells
  • The production of protective response against viral infections
  • The ability to secrete inflammatory cytokines
