Mast Cells
Mast cells are cells of the immune system found in many tissues throughout the body. They play an important role in the body’s response to allergens, pathogens, and stress. Specifically, they express receptors on their surface which can bind different types of molecules, thereby triggering the release of molecules such as histamine, heparin, and cytokines. Histamine is well known for its involvement in allergic reactions, heparin helps to protect against blood clotting, and cytokines are important for stimulating the immune response. Mast cells also play a role in wound healing, angiogenesis, and tissue repair. Mast cells are therefore essential components of the immune system, and are important mediators in the body's response to stress and inflammation.
