Mast cells
Immune system cells that release histamine and other mediators in response to HIT triggers.
Mast cells are a key part of the immune system. In the context of histamine intolerance, they can be activated by various triggers such as food, allergens or stress. Once activated, they release large amounts of histamine and other inflammatory substances, which contribute to the symptoms of HIT.
