Across
  1. 4. / linking together antigens to make larger, increasing phagocytosis
  2. 8. facilitate destruction by eosinophils and or NK cells
  3. 10. / glycoproteins made by B cells that recognize antigens
  4. 11. / the study of reactions between antibodies and antigens.
  5. 13. Serum fraction containing Ab. Can be given to a person as a treatment against a specific antigen
  6. 15. /the generic term for serum because it contains antibodies ( Ab).
  7. 16. / The process of destroying B and T cells that react to self antigens
  8. 19. / Occur when T and/or B cells are activated to produce immune reactions against self-proteins
  9. 20. /Involved in allergic reactions and the lysis of parasitic worms
Down
  1. 1. antibodies act as opsonins to increase phagocytosis
  2. 2. / Crosses placenta; protects fetus and newborn.
  3. 3. antibodies activate MAC lysis by complement
  4. 5. / Involves TH cells (TH2 ), B cells (plasma cells), antibodies.Produces antibodies to destroy invaders.
  5. 6. not making self-reactive antibodies or self-reactive TCRs
  6. 7. / Involves TH cells (TH1), TC cells, phagocytes. Destroys infected host cells.
  7. 9. / first Ab produced in response to infection (primary response)
  8. 12. / Likely to be the first type of antibody an invading microbe would encounter because it is present in mucous membranes (secreted).
  9. 14. / On B cells, initiate immune response with their B cells
  10. 17. / binding to toxins or viruses or bacterial cells to prevent their binding their host cell targets
  11. 18. / a molecule that is recognized as non-self by the immune system.
