The overactivation of NF-κB is intimately involved in many human diseases. Various therapeutic strategies against NF-κB, to date, include anti-inflammatory drugs, antioxidants, immunosuppressive agents, inhibitors of protease and proteasome, prostaglandings, nitric oxide, IL-10, microbial products, synthetic inhibitors, antisense oligonucleotides and decoy deoxyoligonucleotides. Studies are underway to develop NF-κB member-specific and cell type-specific drugs that can inhibit the activation of NF-κB only in target cells and that may become a novel way to treat the human diseases.展开更多
