Innate Immun. 6:563-574(2014). CC -!- FUNCTION: Cytokine with antiviral, antitumour and immunomodulatory CC activities. Plays a critical role in the antiviral host defense, CC predominantly in the epithelial tissues. Acts as a ligand for the CC heterodimeric class II cytokine receptor composed of IL10RB and IFNLR1, CC and receptor engagement leads to the activation of the JAK/STAT CC signaling pathway resulting in the expression of IFN-stimulated genes CC (ISG), which mediate the antiviral state. Has a restricted receptor CC distribution and therefore restricted targets: is primarily active in CC epithelial cells and this cell type-selective action is because of the CC epithelial cell-specific expression of its receptor IFNLR1. Seems not CC to be essential for early virus-activated host defense in vaginal CC infection, but plays an important role in Toll-like receptor (TLR)- CC induced antiviral defense. Plays a significant role in the antiviral CC immune defense in the intestinal epithelium. Exerts an immunomodulatory CC effect by up-regulating MHC class I antigen expression. CC {ECO:0000269|PubMed:15914836, ECO:0000269|PubMed:16618774, CC ECO:0000269|PubMed:18250457, ECO:0000269|PubMed:21518880}. CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250|UniProtKB:Q8IZJ0}.
