title: Nuclear factor-kappaB as a therapeutic target in critical care medicine.
abstract: Nuclear factor-kappaB is a transcriptional factor required for the gene expression of many inflammatory mediators. Nuclear factor-kappaB activation requires removal and degradation of its inhibitor kappaB, an event that occurs after phosphorylation of inhibitor kappaB by a complex of inhibitor kappaB kinases. These events allow nuclear factor-kappaB to translocate into the nucleus, where it binds to kappaB elements and initiates transcription. Inappropriate and prolonged activation of nuclear factor-kappaB has been linked to several diseases associated with inflammatory events, including septic shock, acute respiratory distress syndrome, ischemia, and reperfusion injury. Thus, the key role of nuclear factor-kappaB in regulating inflammation makes this factor a therapeutic target for reducing tissue and organ damage. Regulation and control of nuclear factor-kappaB can be achieved by gene modification strategies or by pharmacologic inhibition of the key components of the cascade that leads to nuclear factor-kappaB activation. The purpose of our review is to describe these novel therapeutic approaches and their potential efficacy.
