Then, the antibodies add to a variety of blood cell known as the mast cell. These could be found in airways, in intestines, and somewhere else. The existence of these mast cells in airways as well as gastrointestinal tract makes the parts more vulnerable to the allergen contact. The allergens combine to IgE that is connected to mast cell. With this, it causes these mast cells to discharge a range of chemicals right into the bloodstream. Histamine, which is considered to be the major chemical, would cause the most of symptoms of allergic reaction. read more
