Descrizione generale

The allergic reaction is mediated through the IgE high affinity receptor (FcεRI). When a multivalent antigen is presented, a redistribution of the monomeric IgE FcεRI receptor complexes causes the degranulation of mast cells and basophils, resulting in the subsequent release of factors responsible for the allergic reaction. The FcεRI receptor is a tetrameric complex, consisting of an a-chain, b-chain and a dimeric g-chain. The a-chain is primarily involved with the binding of IgE, but the signal is transferred through the g subunit, which contains the immunoreceptor tyrosine activation motifs (ITAM) critical for initiating receptor mediated signal transduction through the Syk and Lyn tyrosine kinases. The FcεRI receptor is able to engage and disengage the IgE, providing a versatile model for studying the function of kinase coupled receptors.
