Stimulation of Nicotinamide Adenine Dinucleotide Biosynthetic Pathways Delays Axonal Degeneration After Axotomy

This 2006 study investigates the role of NAD⁺ biosynthesis in axonal protection following injury. Researchers overexpressed various NAD⁺ biosynthetic enzymes and administered their respective substrates in cultured dorsal root ganglion (DRG) neurons. Among the enzymes tested, NMNAT1 exhibited the strongest protective effect against axonal degeneration, while NMNAT3 and a cytoplasm-localized

Nicotinamide Mononucleotide Ameliorates Senescence in Alveolar Epithelial Cells

This study investigates the effects of nicotinamide mononucleotide (NMN) on alveolar epithelial cell (AEC) senescence. NMN supplementation in aged C57BL/6 mice (8–10 months old) and in a bleomycin-induced pulmonary fibrosis model in young mice (6–8 weeks old) demonstrated significant mitigation of age-associated physiological decline in the lungs. In vitro, NMN
