Interleukin-28A (IL-28A) also known as IFNL2 is a novel cytokine that exerts its biological effects through a receptor that also binds IL28B and IL29. IL28A induces phosphorylation of STAT1, STAT2, and STAT31 IL-28A has antiviral activities and stimulates antiviral responses through a heterodimeric receptor. IL-28A represents a potential novel approach for therapy of Th1-mediated inflammatory diseases such as T-cell-mediated hepatitis.2
