Questions and Answers

What is the role of interferons in the anti-viral response?

  • Interferons activate natural killer cells
  • Interferons directly kill virus-infected cells
  • Interferons help to inhibit viral replication and spread (correct)
  • Interferons promote viral mutation for immune evasion

    • What defines the adaptive immune response to viral infection?

  • Activation of natural killer cells
  • Formation of granulomas
  • Production of specific antibodies and memory T cells (correct)
  • Release of interferons

    • How are granulomas developed and maintained in response to intracellular bacteria?

  • Granulomas are a result of viral interference with immune responses
  • Granulomas are formed by the aggregation of immune cells to contain the infection (correct)
  • Granulomas are created by the direct action of bacteria
  • Granulomas are formed by the release of interferons
