Background

IL-28 is a family of cytokines that belongs to interferons termed as λ-interferons or type III interferons (IFN). This family includes IL-28A(IFN-λ2), IL-28B(IFN-λ3) and IL-29(IFN-λ1) in human and IL-28A and IL-28B in mice. IL-28A, IL-28B and IL-29 share a unique heterodimeric receptor IFNLR consisting of IL-28Rα and IL-10R, which is mainly expressed by epithelial cells, dendritic cells (DCs) and macrophages. IL-28B inhibits M2 macrophage polarization in vitro, while also halting M2 macrophage differentiation predominantly via inhibition of the signal transducer and activator of transcription (STAT)3 and c-Jun N-terminal kinase (JNK) signaling pathways. Results reveal a protective role of IL-28B via regulation of epithelial cells in protease induced asthma.
