Visfatin was first identified as a factor that enhanced the differentiation of B-cells. It is a secreted factor that is highly expressed in adipocytes. Intracellularly, visfatin acts as a cytosolic enzyme involved in nicotinamide adenine dinucleotide (NAD) synthesis. Visfatin levels positively correlate with obesity and type 2 diabetes mellitus and can bind the insulin receptor to lower blood sugar. Visfatin is also known as PBEF, PBEF1, Pre-B cell Enhancing Factor 1, NAMPT, and nicotinamide phosphoribosyltransferase.
