Disease

[IFNL3_HUMAN] Response to antiviral treatment in hepatitis C.

Function

[IFNL3_HUMAN] Cytokine with antiviral, antitumour and immunomodulatory activities. Plays a critical role in the antiviral host defense, predominantly in the epithelial tissues. Acts as a ligand for the heterodimeric class II cytokine receptor composed of IL10RB and IFNLR1, and receptor engagement leads to the activation of the JAK/STAT signaling pathway resulting in the expression of IFN-stimulated genes (ISG), which mediate the antiviral state. Has a restricted receptor distribution and therefore restricted targets: is primarily active in epithelial cells and this cell type-selective action is because of the epithelial cell-specific expression of its receptor IFNLR1. Seems not to be essential for early virus-activated host defense in vaginal infection, but plays an important role in Toll-like receptor (TLR)-induced antiviral defense. Plays a significant role in the antiviral immune defense in the intestinal epithelium. Exerts an immunomodulatory effect by up-regulating MHC class I antigen expression.^[1] ^[2]

Publication Abstract from PubMed

Interferon-lambda (IFN-lambda) is an antiviral cytokine that signals through a distinct receptor complex, composed of the IFN-lambdaR1 and interleukin-10R2 (IL-10R2) receptor chains. We have determined the crystal structure of human IFN-lambda3 and characterized the interaction with its receptor complex through structure-based site-directed mutagenesis. The ability of IFN-lambda3 mutants to signal was determined by measuring the antiviral activity and induced STAT2 phosphorylation. In conclusion, our data show that, although IFN-lambda is functionally an interferon, it is clearly structurally related to members of the IL-10 family. In particular, we found an interesting similarity between IFN-lambda and IL-22, and we suggest that IFN-lambda and IL-22 possess parallel functions, protecting epithelial tissue against viral and bacterial infections, respectively.
