B Cell Activating Factor Receptor
Receptors present on a wide variety of hematopoietic and non-hematopoietic Cell types that are specific for Interleukin-4. They are involved in signaling a variety of immunological responses related to allergic Inflammation including the differentiation of Th2 Cells and the Regulation of Immunoglobulin E production. Two subtypes of receptors exist and are referred to as the Type I Interleukin-4 Receptor and the Type II Interleukin-4 Receptor. Each receptor subtype is defined by its unique subunit composition.
