NAD⁺ metabolism controls inflammation during senescence

We have recently discovered that nicotinamide adenine dinucleotide metabolism controls the pro-inflammatory senescence-associated secretory phenotype during cellular senescence. This newly discovered epigenetic-metabolic signaling axis, mediated by high mobility group A and nicotinamide phosphoribosyltransferase, drives key metabolic changes and pro-inflammatory responses of senescent cells that fuel cancer...
