Across
  1. 1. T cells that recognize antigen presented via MHC II, express CD4, and activate other immune cells
  2. 5. The small, accessible part of an antigen that binds to an antigen receptor
  3. 6. Regions that give the B-cell receptors their antigen-binding specificity
  4. 7. Immunization that provides temporary protection without inducing immunological memory
  5. 8. Active artificial immunization that stimulates a primary response and a memory response to a pathogen
  6. 9. Cells that “record” information to help fight a pathogen if it comes back
  7. 13. Cells that actively secrete antibodies
  8. 15. Soluble molecules secreted by plasma cells that bind to antigens
  9. 16. T cell receptors
Down
  1. 2. Key players of adaptive immunity
  2. 3. A process in which host proteins display antigen fragments on the cell surface
  3. 4. Which type of adaptive immune response defends against infection by directly killing or by modulating the immune response?
  4. 10. T cells that recognize antigens presented via MHC I, express CD8, and directly destroy targeted cells
  5. 11. Which adaptive immune response uses antibodies to defend against infection in body fluids?
  6. 12. Antigen receptors on B cells
  7. 14. Substances that can elicit a response from a B cell or T cell
  8. 16. Subset of helper T cells that promotes a humoral response
