According to new data, overexpression of the nicotinamide adenine dinucleotide (NAD) hydrolase, CD38, in systemic sclerosis (SSc) leads to NAD depletion and fibrosis. These intriguing findings link inflammation, NAD metabolism and fibrosis and bare striking resemblance to age-related changes in SSc. Could DNA damage also connect these seemingly unrelated pathways?
