  1. 3. antibody producing "machine"
  2. 5. produced by a B cell or its plasma cell offspring and released into the body fluids where it attaches to antigens, causing neutralization, precipitation, or agglutination, which marks the antigens for destruction by phagocytes or complement
  3. 6. Descendent of an activated B cell or T cell; generated during the initial immune response (primary response); may exist in the body for years thereafter, enabling it to respond quickly and efficiently to subsequent infections or meetings with the same antigen
  4. 7. any of the several cell types(macrophage, dendritic cell, B cell) that engulfs and digests antigens that it encounters
  5. 10. Like perforin, causes cell killing; attracts granulocytes; activates T cells and macrophages.
  6. 11. a T cell that binds with a specific antigen presented by an APC & stimulates the production other immune cells
Down
  1. 1. Slows or stops the activity of B and t cells once the infection has been conquered. Thought to be important in preventing autoimmune disease
  2. 2. lymphocyte that resides in the lymph nodes, spleen, or other lymphoid tissues, where it is induced to replicate by antigen-binding and helper T cell interactions
  3. 4. group of bloodborne proteins activated after binding to anti-body covered antigens
  4. 7. called a killer T cell, activity enhanced by helper T cells, its specialty is killing virus-invaded body cells, as well as body cells that have become cancerous; involved in graft rejection
  5. 8. Chemicals released by sensitized T cells, macrophages, and certain other cells
  6. 9. substance capable of provoking an immune response
