What is IL-29 (IFN-λ1)?

Interleukin 29 (IL-29, IFN-λ1) is at type III interferon. Presently, three type III interferons are described: IFN-λ1, IFN-λ2, and IFN-λ3. Similar to type I interferons, IL-29 is mainly produced by monocytes and dendritic cells in response to viral infections. Among other anti-viral effects, IL-29 induces upregulation of MHC class I on the surface of the virus-infected cell.
