Human IL28A, 50 ug

IL 28A is one of type III interferons, which are upregulated in response to viral infection as antiviral molecules, and they act predominantly on epithelial cells through a receptor complex that contains IL-10 R beta and IL-28 R alpha /IFN-gamma R1, and induce the upregulation of MHC class I antigen. IL-28A promotes the Th1 polarization of dendritic cells in the airway and inhibits Th2 and Th17 mediated inflammation. In addition, IL-28A has anti-tumor activity (1-5).
