Paper

Abstract

Calcific aortic valve disease lacks effective pharmacotherapy and is tightly linked to ageing. Since nicotinamide adenine dinucleotide (NAD+) steadily declines with age, this study investigated whether cell-type-specific disruption of NAD+ salvage metabolism drives valvular inflammation and calcification.

Research summary

The paper claims that disruption of NAD+ salvage metabolism in specific cell types drives valvular inflammation and calcification. This research is relevant as it explores the metabolic alterations associated with aging that contribute to a specific age-related disease, potentially addressing underlying mechanisms rather than just symptoms.
