Visfatin/NAMPT (nicotinamide phosphoribosyltransferase) is a protein with several suggested functions. Although the first discovery of this molecule as a pre-B-cell colony-enhancing factor suggested primarily a cytokine function, its rediscovery as the key enzyme in nicotinamide adenine dinucleotide generation has considerably widened its potential biological activities. Although originally thought to be produced in adipose tissue (i.e., adipocytes and infiltrating macrophages), its production seems to involve other cells and tissues such as skeletal muscle, liver, immune cells, cardiomyocytes, and the brain. Visfatin/NAMPT has both intracellular and extracellular effects influencing several signaling pathways. Its broad spectrum of effects is mirrored by its potential involvement in a wide range of disorders including human immunodeficiency virus infection, septicemia, myocardial failure, atherosclerosis, metabolic disorders, inflammatory diseases, malignancies, and neurodegenerative disorders and aging. Moreover, studies on visfatin/NAMPT in atherosclerotic disorders suggest a rather complex role of this molecule in pathophysiology, potentially mediating both adaptive and maladaptive responses.

Nicotinamide phosphoribosyltransferase (Nampt) is also called visfatin or pre-B-cell colony-enhancing factor. The functions of Nampt have been reported as a cytokine, an adipokine and the rate-limiting enzyme in nicotinamide adenine dinucleotide biosynthesis. As a pleiotropic multifunctional protein, Nampt is involved in a variety of physiological and pathological conditions including innate immunity, metabolic disorders, and stress; and Nampt also participates in inflammatory disorders such as acute lung injury, atherosclerosis, myocardial infarct, obesity, type 2 diabetes, and rheumatoid arthritis. The studies indicate that Nampt might be a potential target for pharmacological intervention against inflammatory diseases. We review research advances on the roles of Nampt in inflammation.
