NF-κB target gene products with a central role in innate and adaptive immune responses include a wide spectrum of cytokines and chemokines that mediate the exacerbated inflammation triggered by the host in response to viral infections, receptors required for neutrophil adhesion and transmigration across blood vessel walls, members of the major histocompatibility complex (MHC), and proteins involved in antigen presentation (Pahl, 1999). This evidence concerns the gene NFKB1 and viral infectious disease.
