Signal transduction pathway and blocking strategies of NF-?B / 中国病理生理杂志

ABSTRACT

NF-?B is thought of as a genetic switch to control expressions of many target genes and directly participates in pathogenesis of infection, inflammation, stress, immunoresponse, cellular apoptosis, toxic shock and tumor as well as cell-cycle regulation and cell differentiation. The overactivation of NF-?B is intimately involved in many human diseases. Various therapeutic strategies against NF-?B, 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-?B member-specific and cell type-specific drugs that can inhibit the activation of NF-?B only in target cells and that may become a novel way to treat the human diseases.
