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] .

2023年7月28日 · inampt抑制剂和enampt中和抗体在许多疾病中具有抗炎特性，如类风湿关节炎、急性肺损伤、败血症、缺血、炎症性肠病(ibd)和癌症。即inampt/enampt升高的疾病。 总结

2019年8月6日 · Increasing eNAMPT promotes NAD + in tissues, enhancing their functions and extending healthspan. eNAMPT is carried in small particles called extracellular vesicles (EVs). Supplementing eNAMPT-containing EVs improves physical activity and extends lifespan in mice, revealing a novel mechanism by which eNAMPT regulates systemic NAD + biosynthesis ...

Extracellular NAMPT (eNAMPT, also called visfatin or pre-B-cell colony enhancing factor) has been shown to possess adipocytokine, pro-inflammatory, and pro-angiogenic activities.

2025年1月27日 · Among several predictions from the NAD World 2.0, the most critical one is that the secretion of extracellular NAMPT (eNAMPT) from adipose tissue is a key inter-tissue communication between the...

eNAMPT被认为是粒细胞集落刺激因子（G-CSF）诱导的髓系分化的重要因子，对不同细胞类型（即免疫细胞和癌细胞）具有旁分泌和自分泌作用，结合TLR4。 NAMPT 在结构和功能上与烟酸磷酸核糖基转移酶 (iNAPRT) 相关，iNAPRT 在从烟酸开始的 NAD 补救途径中是限速的。 NAMPT和NAPRT控制的NAD生物合成途径紧密相连，可以相互补偿。 还，NAPRT 被鉴定为 TLR4 的细胞外配体 (eNAMPRT) 和炎症介质 (Managò et al., 2020)。 重要的是，iNAMPT 和 …

2023年10月16日 · Extracellular NAMPT (eNAMPT, also called visfatin or pre-B-cell colony enhancing factor) has been shown to possess adipocytokine, pro-inflammatory, and pro-angiogenic activities.

Nicotinamide phosphoribosyltransferase (NAMPT) is an intracellular enzyme involved in nicotinamide adenine dinucleotide (NAD) production and it has been previously shown that its inhibition leads to a reduction in tumor growth due to energetic depletion of the cancer cell as well as an effect of myeloid derived suppressor cells.5 Yet, this ...

烟酰胺磷酸核糖转移酶 (NAMPT) 是一种限速酶，在哺乳动物烟酰胺腺嘌呤二核苷酸 (NAD +) 合成补救途径中，它催化烟酰胺 (NAM) 和磷酸核糖焦磷酸转化为烟酰胺单核苷酸 (NMN)。 NAMPT 以两种形式存在，即细胞内 NAMPT (iNAMPT) 和细胞外 NAMPT (eNAMPT)。 iNAMPT 水平在棕色脂肪组织 (BAT)、肝脏和肾脏中较高，在白色脂肪组织 (WAT)、肺、脾、睾丸和骨骼肌中处于中等水平，在脑和胰腺中检测不到。 eNAMPT 被认为是通过 iNAMPT 的翻译后修饰产生的，主要 …

2023年10月17日 · In this review, we summarize the current state of knowledge on eNAMPT biology, proposed roles in disease pathogenesis, and its potential as a disease biomarker. We also briefly discuss the emerging therapeutic approaches for eNAMPT inhibition.
