Exam 14: Immediate Hypersensitivity

Matching 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

Matching 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

Matching 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

Matching 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

Matching 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

Matching 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

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

Matching 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
