IL-4 mediates ist function by binding to receptors expressed on target cells. The IL-4 receptors exhibit an affinity of approximately 10-10 M.

Receptors exist on freshly prepared B and T lymphocytes and macrophages, as well as on various cell lines including lymphoid cells, mast cell lines, a variety of other hematopoietic cell lines, fibroblasts and stromal cell lines. On T and B cells, receptors are present in low numbers (appr. 400), which are reported to be upregulated by IL-2 and IL-4.

IL-4 is produced by a particular subset of T helper cells, the TH2 cells. These cells tend to make a specific set of lymphokines including IL-4, IL-5, IL-6, IL-10, IL-13 and GM-CSF and fail to produce IL-2, IFNg, and lymphotoxin (TNFb). Apart from T cells, it has been shown that mast cells can produce IL-4.

IL-4 exerts numerous effects on various hematopoietic cell types. On B cells, IL-4 promotes immunological class switching to IgE and IgG1 isotypes and upregulates MHC class II and CD23 expression. It can promote survival, growth, and differentiation of both T and B lymphocytes, mast cells, and endothelial cells.

In addition, IL-4 can inhibit the production of TNF, IL-1, and IL-6 by macrophages.
