Interferon lambda 4 impairs hepatitis C viral antigen presentation and attenuates T cell responses
Abstract
A genetic variant in the IFN-lambda 4 gene has been associated with poor hepatitis C virus prognosis but it is not clear how this functions. Here the authors show that IFN-lambda 4 promotes ER stress and inhibits presentation of HCV epitopes to CD8+ T cells.
