Human IL4 mRNA encodes the human interleukin 4 (IL4) protein, a pleiotropic cytokine produced by activated T cells. IL4 is considered an important cytokine for tissue repair, counterbalancing the effects of proinflammatory type 1 cytokines, however, it also promotes allergic airway inflammation. Moreover, IL-4 mediates and regulates a variety of human host responses such as allergic, anti-parasitic, wound healing, and acute inflammation.
