BACKGROUND: Nuclear factor-kappa B (NF-kappa B) is a family of transcription factors that is recognized by the kappa B enhancer element. Numerous proinflammatory genes have binding sites for NF-kappa B, and the products of these genes are an integral part of cellular activation and inflammatory response systems. Because there is a close relationship between NF-kappa B and mediators of cell activation, it is possible that a disruption of NF-kappa B-activating pathways may effectively influence mesangial cell activation. METHODS: We reviewed available studies related to both NF-kappa B and mesangial cells in order to provide evidence for the role of NF-kappa B in mesangial cell activation. RESULTS: Studies reported by this laboratory and others showed that various experimental maneuvers that modulate NF-kappa B activation result in a parallel modulation of proinflammatory molecule production in cultured mesangial cells. Likewise, the ability of the inhibitors of NF-kappa B activation to down-regulate the inflammatory response in animal models of renal disease has been recently demonstrated. CONCLUSIONS: These data suggest a pivotal role of NF-kappa B in mesangial cell activation and designate it as an obvious target for the modulation of this activation. Studies are necessary to characterize the role of NF-kappa B in human renal injury.
