  1. 3. These cells have receptors that react directly with antigens in the blood.
  2. 4. These antibodies are produced to target only one specific epitope.
  3. 6. Vaccines contain these types of pathogens, which are modified to trigger an immune response
  4. 7. What term refers to foreign molecules that stimulate an immune response?
  5. 8. Lymphocytes that mature in this organ become T cells.
  6. 12. This type of MHC protein is displayed on macrophages after they engulf a pathogen

  1. 1. These cells arise from activated B cells and produce antibodies.
  2. 2. Memory cells are in this phase of the cell cycle when they are not actively dividing.
  3. 5. These cells are activated by infected cells and are responsible for killing those infected cells
  4. 7. This Y-shaped protein binds to specific antigens to help neutralize pathogens.
  5. 9. These proteins released by Cytotoxic T cells create pores in the membrane of infected cells.
  6. 10. These cells persist in the body and are similar to the original B cells, ready for future encounters with the same antigen.
