General description
Interleukin-13 (UniProt: P35225; also known as IL-13) is encoded by the IL13 (also known as NC30) gene (Gene ID: 3596) in human. IL-13 is an extracellular/secreted glycoprotein that is synthesized with a signal peptide (aa 1-24), which is subsequently cleaved off to generate the mature form. IL-13 is an immunoregulatory cytokine that is released predominantly by CD4+ and CD8+ T cells and by mast cells and eosinophils and regulates the function of human B cells and monocytes. It is closely related to IL-4 in its biological function but, in general, the responses of cells to IL-13 appear to be smaller in magnitude. Both IL-4 and IL-13, independently of each other, are able to induce IgE antibody production. The intracellular site of storage of IL-13 in eosinophils is associated with the crystalloid granules, indicating that IL-13 is a preformed mediator and is released upon stimulation of degranulation. IL-13 signaling is mediated through a shared multi-subunit heterodimeric receptor complex consisting of IL-4R and IL-13R1. This heterodimerization activates STAT6 and most of the biological effects of IL-13 have been linked to STAT6 activation. IL-13 inhibits the production of pro-inflammatory cytokines but can up-regulate the synthesis of IL-12 in dendritic cells and macrophages. IL-13 is typically associated with allergic inflammation, including asthma. It induces many features of allergic lung disease, including airway hyperresponsiveness, goblet cell metaplasia, and glycoprotein hypersecretion, which all contribute to airway obstruction.
