Inflammation and the Metabolic Syndrome: The Tissue-Specific Functions of NF-kappa B

Obesity is becoming a major health concern in Western society, and medical conditions associated with obesity are grouped in the metabolic syndrome. Overnutrition activates several proinflammatory signaling pathways, leading to a condition of chronic low-grade inflammation in several metabolic tissues affecting their proper function. Nuclear factor kappa B (NF-kappa B) signaling is a crucial pathway in this process and has been studied extensively in the context of obesity and the metabolic syndrome. Here we give an overview of the molecular mechanisms behind the inflammatory function of NF-kappa B in response to overnutrition and the effect this has on several metabolic tissues.
