Interferon-λ in the context of viral infections: production, response and therapeutic implications.

ABSTRACT: Interferon (IFN)-λ forms the type III IFN family. Although they signal through distinct receptors, type I (IFN-α/β) and type III IFNs elicit remarkably similar responses in cells. However, in vivo, type III and type I IFN responses are not fully redundant as their respective contribution to the antiviral defense highly depends on virus species. IFN-λ is much more potent than IFN-α/β at controlling rotavirus infection. In contrast, clearance of several other viruses, such as influenza virus, mostly depends on IFN-α/β. The IFN-λ receptor was reported to be preferentially expressed on epithelial cells. Cells responsible for IFN-λ production are still poorly characterized but seem to overlap only partly IFN-α/β-producing cells. Accumulating data suggest that epithelial cells are also important
