Summarize this article for a 10 year old
Nicotinamide phosphoribosyltransferase (NAmPRTase or NAMPT), formerly known as pre-B-cell colony-enhancing factor 1 (PBEF1) or visfatin for its extracellular form (eNAMPT),[5] is an enzyme that in humans is encoded by the NAMPT gene.[6] The intracellular form of this protein (iNAMPT) is the rate-limiting enzyme in the nicotinamide adenine dinucleotide (NAD+) salvage pathway that converts nicotinamide to nicotinamide mononucleotide (NMN) which is responsible for most of the NAD+ formation in mammals.[7] iNAMPT can also catalyze the synthesis of NMN from phosphoribosyl pyrophosphate (PRPP) when ATP is present.[8] eNAMPT has been reported to be a cytokine (PBEF) that activates TLR4,[9] that promotes B cell maturation, and that inhibits neutrophil apoptosis.
