Mechanisms of Nonimmunological Histamine and Tryptase Release from Human Cutaneous Mast Cells

Abstract: Tryptase is not a specific marker of mast cell activation (ie., anaphylaxis), and signaling mechanisms for mast cell activation involve activation of phospholipase C and phospholipase A2 pathways that are also involved in other cellular activation mechanisms.

“…That is in accordance with mechanisms proposed in reactions to muscle relaxants, which are not always driven by an immunologic process (e.g., IgE against ammonium group). Some anaphylactoid reactions are due to nonimmunologic stimulation and lead to histamine and tryptase release as well (4). Thus, it is consistent to find a negative specific IgE along with a positive CD63 test since our protocol investigates the common final feature of both mechanisms, which is basophil degranulation.…”
