Summary
IFNL1, IFNL2 and IFNL3 (IL28B) have different effects on Toll-like receptor-related gene expression in HepG2 cells.
The IFNL3 SNP rs4803217 is critical for the outcome of hepatitis C virus (HCV) infec¬tion by controlling the stability of IFNL3 mRNA. HCV induces two microRNAs, MIR499A and MIR208B, that target the polymorphic region of the IFNL3 3� UTR.
Entrez Gene
Summary This gene encodes a cytokine distantly related to type I interferons and the IL-10 family. This gene, interleukin 28A (IL28A), and interleukin 29 (IL29) are three closely related cytokine genes that form a cytokine gene cluster on a chromosomal region mapped to 19q13. Expression of the cytokines encoded by the three genes can be induced by viral infection. All three cytokines have been shown to interact with a heterodimeric class II cytokine receptor that consists of interleukin 10 receptor, beta (IL10RB) and interleukin 28 receptor, alpha (IL28RA).
