Introduction	Interleukin-4, also known as B-cell stimulatory factor 1, is a pleiotropic cytokine which interacts with multiple cell lineages, including T cells, fibroblasts and haematopoietic cells, and is one of the most important factors involved in B cell IgG1 and IgE class switching. Excessive secretion of IL-4 by Th2 helper cells, has been linked with allergy and elevated IgE levels.
