The symptoms began minutes after he started eating a lobster dinner. It is determined that his symptoms are due to surface crosslinking of IgE. This immunologic event most likely caused the release of which of the following?? A: Tryptase, B: Cathepsin, C: Serotonin, D: Bradykinin, E: Interferon gamman,  <response>: This is a question about the pathophysiology of an allergic reaction. The patient developed symptoms of anaphylaxis shortly after eating lobster, suggesting an IgE-mediated food allergy. The question asks which mediator is most likely released as a result of crosslinking of IgE on mast cells and basophils. The choices include tryptase, cathepsin, serotonin, bradykinin, and interferon gamma. Tryptase is one of the main mediators released by mast cells during an allergic reaction, so this is likely the correct answer. The other choices are not primary mediators released during an IgE-mediated reaction.A: Tryptase
