Impact of holder pasteurization on protein and eNAMPT/Visfatin content in human breast milk.

Human milk proteins, a mixture of whey proteins including caseins, milk fat globule membrane (MFGM) proteins, various peptides, and their amino acids, play a crucial role in infant growth and development, as do non-nutritional bioactive components. The extracellular nicotinamide phosphoribosyltransferase (eNAMPT) or visfatin is a conserved cytokine/enzyme released by many mammalian cells, related to multiple metabolic and immune processes. Few investigations have been reported about detecting visfatin in skimmed milk and the hypothesis of its potential role in regulating infant adiposity through breast milk.
