Relevance of new drug discovery to reduce NF-κB activation in cardiovascular disease

Abstract

The transcription factor nuclear factor-κB (NF-κB) is a main regulator of the expression of several genes involved in the activation of inflammation, cell proliferation, cell immunity and apoptosis. Excess or inappropriate activation of NF-κB has been observed in human inflammatory diseases, including atherosclerosis. Because of the extensive involvement of NF-κB signaling in human diseases, efforts have been made in developing inhibitors of this pathway. Here we will provide an overview of the biology of NF-κB activation pathways. We will here especially focus on current knowledge of the role of the classical ("canonical") NF-κB activation pathway as a potential therapeutic target for anti-atherosclerotic therapies in clinical applications, and discuss classical and novel therapeutic strategies to reduce its prolonged activation.
