Background

Interleukin 4 (IL-4) is a pleiotropic cytokine produced primarily by activated T lymphocytes, mast cells and basophils .

The cDNA sequence of mouse IL-4 predicts a 140 amino acid (aa) residue precursor protein containing a 20 aa residue signal peptide that is cleaved to form the mature protein . At the amino acid sequence level, mature mouse IL-4 is approximately 50% identical to human IL-4 but there is no species cross-reactivity for biological activity for the two proteins . Mouse IL-4 also shares approximately 30% amino acid sequence identity to mouse IL-13 and the two cytokines exhibit overlapping biological activities . The gene for IL-4 has been mapped to mouse chromosome 11, in close proximity to the genes for IL-3, IL-5, IL-13 and GM-CSF .

IL-4 has multiple immune response-modulating activities on a variety of cell types. It is an important regulator of isotype switching, inducing IgE production in B lymphocytes. It is an important modulator of the differentiation of precursor T helper cells to the Th2 subset that mediates humoral immunity and modulates antibody production. In addition, IL-4 has also been shown to have anti-tumor activity both in vivo and in vitro .

The biological effects of IL-4 are mediated by specific cell surface receptor complexes. Although IL-4 R does not bind IL-13 directly, it has been shown to complex with the low-affinity IL-13 R to form the functional high-affinity receptor complex for IL-13 . In addition to the membrane-bound form of IL-4 R, a naturally occurring soluble form of IL-4 R has been identified in human and mouse biological fluids and in mouse cell culture supernates . Soluble IL-4 R has been to shown to bind IL-4 with high affinity in solution.
