  • Overview of IFNL1 molecular targets


    Interleukin 29 (IL-29), also known as interferon λ1 (IFN-λ1), is a member of the helical cytokine family and a type III interferon. Its amino acid sequence is highly similar to another type III interferon, IL-28. The IL-29 gene is found on chromosome 19 in humans, but is not present in the mouse genome. IL-29 plays an important role in host defense against microorganisms, and its gene is highly upregulated in virus-infected cells. IL-29 has significant antiviral activity and immunomodulatory properties, inhibiting viral replication by inducing cellular antiviral responses similar to those activated by IFN-α/β. However, IL-29 binds to a unique receptor, so during natural infection, this cytokine may synergize with IFN-α/β or IFN-γ to inhibit viral replication, and may also be used in combination with other cytokines to treat chronic viral infections such as hepatitis C (HCV). The antiviral activity of IL-29 includes upregulation of class I MHC expression on the cell surface and upregulation of PKR expression. The ligand/receptor complex appears to signal through the Jak-STAT pathway.
