Interleukin 13 (IL-13) is a single-chain cytokine which belongs to the IL13/IL4 family. In humans, IL13 is secreted by many cell types, but especially by T helper type 2 (Th2) cells. IL13 inhibits the production of pro-inflammatory cytokines and chemokines, and thus down-regulates macrophage activity. Meanwhile, IL-13 synergizes with IL2 in regulating IFN-gamma synthesis. IL-13 binds to a multi-subunit receptor comprising the alpha chain of the IL-4 receptor (IL-4Ralpha) and at least one of two known IL-13-specific binding chains (IL13 Ralpha1 and IL13 Ralpha2), and exerts its effects through signal transducer and activator of transcription 6 (STAT6), like IL-4. Accordingly, IL-13 may be critical in regulating inflammatory and immune responses as a central mediator in various cell types.
