Across
  1. 5. 3-6 Death receptor
  2. 8. Antibodies attaching to viral receptors
  3. 9. (initials) Protein on surface of cell signalling to T cells
  4. 10. Signal to warn nearby cells of virus
  5. 11. 9-1-4 Leucocyte that kills viruses
  6. 12. Can't live without host
  7. 13. intracellular antibody receptor that recruits ubiquitin-proteasome system to destroy virus
Down
  1. 1. 7-6-4 Can use either antibody or MHC to recognise and kill infected cell
  2. 2. released by killer cell resulting in osmotic lysis
  3. 3. triggers opsonisation and phagocytosis or MAC Lysis
  4. 4. antibodies binding to many virus particles for easier targeting
  5. 6. activate caspase and endonuclease activation leading to apoptosis
  6. 7. destroys pathogen by engulfing
