WebMast cells can be activated by a variety of agents. However, allergic reactions are generally associated with crosslinking of the high affinity Fc receptor for immunoglobulin E (IgE), FcεRI, with multivalent antigen . High affinity FcεRI is comprised of an IgE-binding α chain, a signal enhancing β chain, and two signal transducing γ chains. WebAbstract The high affinity receptor for immunoglobulin E (designated FcεRI) is the member of the antigen (Ag) receptor superfamily responsible for linking pathogen- or allergen-specific IgEs with cellular immunologic effector functions. This review provides background information on FcεRI function combined with more detailed summaries of …
