General description

Visfatin, also known as pre-B cell colony-enhancing factor, is a cytokine that is highly expressed in visceral fat and was originally isolated as a secreted factor that synergizes with IL-7 and stem cell factors to promote the growth of B cell precursors

Visceral and subcutaneous adipose tissue display important metabolic differences that underlie the association of visceral obesity with obesity-related cardiovascular and metabolic alterations. Recently, visfatin was identified as an adipokine, which is predominantly secreted from visceral adipose tissue both in humans

In mammals, nicotinamide phosphoribosyltransferase (NAMPT) is an adipokine produced by adipose tissue that is found in intracellular and extracellular compartments. The intracellular form of NAMPT is a nicotinamide phosphoribosyltransferase, whereas the extracellular form is considered an adipokine. In humans, NAMPT
