Across
- 3. Antibodies to the erythrocyte antigens of the A or B type.
- 7. The most abundant class of plasma antibodies
- 8. General term for products of arachidonic acid metabolism;function as important inflammatory mediators.
- 11. The class of antibodies secreted by cells lining the GI, respiratory and genito-urinary tracts.
- 12. Leukocytes involved in destruction of parasites and in immediate hypersensitivity response.
- 14. Cells that differentiate from activated B lymphocytes and secrete antibodies.
- 15. Leukocytes that function as phagocytes and also release chemicals involved in inflammation.
Down
- 1. Tissue cells that bind IgE and release inflammatory mediators in response to parasites and immmediate hypersensitivity.
- 2. An inflammatory mediator secreted mainly by mast cells; acts on microcirculation to cause vasodilation and increased permeability to protein.
- 4. Immunoglobulins secreted by plasma cells; combine with the type of antigen that stimulated their production and direct an attack against the antigen or a cell bearing it.
- 5. A type of leukocyte; leaves the bloodstream and is transformed into a macrophage.
- 6. Peptides that split from kininogens in inflamed areas and facilitate the vascular changes associated with inflammation; they also activate neuronal pain receptors.
- 9. General name given to any chemical mediator that promotes phagocytosis.
- 10. Cells that carry out phagocytosis and serve as antigen-presenting cells.
- 13. B cells and cytotoxic T cells that differentiate during an intitial immune response and respond rapidly during a subseguent exposure to the same antigen.
