Overview:
Interleukin 4 (IL-4) is a pleiotropic cytokine produced by activated T lymphocytes, CD3+ cells, NK-T cells, mast cells, eosinophils, and basophils.1 IL-4 has multiple immune response modulation functions 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 antitumor activity both in vivo and in vitro.1
