IL-4R alpha (IL-4 RA; CD124) is a B cell stimulatory factor (BSF) receptor and one of the anti-inflammatory cytokines, and highly expressed in activated T-cells[1]. IL-4 RA participates in forming two interleukin receptors in different cell types. For the type I receptor, depends on IL-4 RA binding IL-4 to recruit IL-2R gamma chain in immune cells. IL-2R gamma is the common subunit for a variety of interleukin receptors, involves in the stimulation of neutrophil phagocytosis by IL-15. For the type II receptor, depends on IL-4 RA binding IL-4 to recruit IL-13R alpha 1 chain. IL-13R alpha 1 is an alternat accessory protein to the common cytokine receptor gamma chain in non-immune cells[2][3]. IL-4 RA generates a soluble form by alternate splicing or proteolysis, maintaining ligand binding properties and inhibiting IL-4 bioactivity. IL-4 RA soluble isoform is produced by proteolytic cleavage at the cell surface (shedding) by a metalloproteinase[4]. IL-4 RA plays an important role in Th2-biased immune responses, alternative macrophage activation, mucosal immunity, allergic inflammation, tumor progression, and atherogenesis[5].
