The elusive NMN transporter is found

Strategies to restore levels of the enzyme cofactor nicotinamide adenine dinclueotide (NAD) late in life to maintain health by treatment with NAD precursors, such as nicotinamide mononucleotide (NMN), represent an exciting area of research in aging and age-related diseases. A study in Nature Metabolism provides an answer to the hotly debated yet fundamental question: how NMN actually gets into cells.
