B cells = white blood cell produced in bone marrow and produce antibodies.
IgE antibodies = antibodies produced during an immune response.
Mast cells = cells of the immune system that produce histamine.
Histamine = chemical released when IgE antibodies bind to mast cells
When a person with an allergy is exposed to an allergen their immune system recognises it as non-self.
B cells then produce IgE antibodies - these antibodies belong to the immunglobin E group that are produced during immune response.
The IgE antibodies bind to mast cells which are found in all tissues
When the allergen binds to the IgE antibodies on the mast cell, histamine is released.
Histamine is what produces the symptoms of an allergy.
