Background

IL28B is a type III IFN, which shares many of the biological effects of type I IFNs but may have fewer side effects due to a more selective receptor distribution. It interacts with a heterodimeric class II cytokine receptor that consists of interleukin 10 receptor, beta (IL10RB) and interleukin 28 receptor, alpha (IL28RA) (PMID: 20712453;12469119;16539846).
