Sensitization is an "immunization" process caused by the "exposure to allergens that results in the development of hypersensitivity"[1].
The first exposure to an antigen will lead to sensitization which results in the development of allergic reaction for subsequent exposures[2].
During the first exposure to antigen, B lymphocytes that detect the antigen will stimulateImmunoglobulin E (IgE) antibodies production[2]. The 'binding of IgE antibodies to high affinity IgE receptors, FcεRI on the surface of mast cells' will lead to the formation of 'IgE binding cells'[2].
Through these steps, the individual has become sensitized to that antigen [3]. The subsequent exposure to the same allergens will trigger the activation of IgE binding cells (mast cells) to secrete the granule contents which cause the allergic symptoms[4].
