Across
  1. 2. found on macrophages, dendritic cells, and B cells, it binds to CD4 molecules on T cells
  2. 4. apoptosis-inducing substance contained in granules of NK cells and cytotoxic T cells
  3. 6. molecule in NK cell and cytotoxic T cell granules that form pores in the membrane of a target cell
  4. 8. early induced proteins made in virally infected cells that cause nearby cells to make antiviral proteins
  5. 10. found on most cells of the body, it binds to the CD8 molecule on T cells
  6. 12. selection against thymocytes in the thymus that react with self-antigen
  7. 17. clusters of rapidly proliferating B cells found in secondary lymphoid tissues
  8. 18. cells that secrete cytokines that enhance the activity of macrophages and other cells
  9. 19. main blood antibody of late primary and early secondary responses; passed from carrier to unborn child via placenta
  10. 21. unencapsulated patches of lymphoid tissue found throughout the body
Down
  1. 1. vasoactive mediator in granules of mast cells and is the primary cause of allergies and anaphylactic shock
  2. 3. soluble, long-range, cell-to-cell communication molecule
  3. 5. T lymphocytes with the ability to induce apoptosis in target cells
  4. 7. enhancement of phagocytosis by the binding of antibody or antimicrobial protein
  5. 9. stimulating growth of lymphocytes that have specific receptors
  6. 11. relatively slow but very specific and effective immune response controlled by lymphocytes
  7. 13. molecule recognized by the receptors of B and T lymphocytes
  8. 14. ability of B cells to change the class of antibody they produce without altering the specificity for antigen
  9. 15. cells that secrete cytokines that induce B cells to differentiate into antibody-secreting plasma cells
  10. 16. immunity developed from an individual’s own immune system
  11. 20. soluble, short-range, cell-to-cell communication molecule
