Exam 9: Immediate-Hypersensitivity

Match the definitions in questions with the mast cell mediator (A-G)that most closely matches it. -Cyclooxygenase-pathway product of arachidonic acid metabolism that causes vascular dilatation,smooth muscle contraction,and neutrophil chemotaxis

All of the following are key mediators of immediate hypersensitivity reactions EXCEPT:

Immediate hypersensitivity differs from delayed-type hypersensitivity in which one of the following ways?

Match the definitions in questions with the mast cell mediator (A-G)that most closely matches it. -Protein constituent of granules that contributes to tissue damage in immediate hypersensitivity reactions

Match the definitions in questions with the mast cell mediator (A-G)that most closely matches it. -Membrane phospholipid derivative that causes bronchoconstriction,retraction of endothelial cells,and relaxation of vascular smooth muscle

Match the definitions in questions with the mast cell mediator (A-G)that most closely matches it. -Lipoxygenase-pathway product of arachidonic acid metabolism that causes prolonged bronchoconstriction,mucus secretion,and increased vascular permeability

Match the definitions in questions with the mast cell mediator (A-G)that most closely matches it. -Soluble factor that promotes eosinophil maturation and activation

Match the definitions in questions with the mast cell mediator (A-G)that most closely matches it. -Biogenic amine that transiently increases vascular permeability and smooth muscle contraction

Which of the following is the most common disorder of immunity that affects 20% of all individuals in the United States?

Match the definitions in questions with the mast cell mediator (A-G)that most closely matches it. -Soluble factor that promotes inflammation and late-phase reaction and activates endothelial expression of adhesion molecules critical for sequential neutrophilic infiltrate
