Quizplus · Accepted Answer

Anaphylaxis is characterized by the degranulation of mast cells, which results in the release of chemical mediators such as histamine, prostaglandins, and leukotrienes. This leads to systemic effects such as hypotension, bronchoconstriction, and edema. While IgG and T-cell mediators can be involved in some immune responses, they are not the primary mechanisms involved in the pathophysiology of anaphylaxis.
