Alpha-ketoglutarate accelerates granulocyte-monocyte progenitor differentiation and atherosclerotic plaque inflammation via oxoglutarate receptor 1.
This animal study found that a high-fat diet increases alpha-ketoglutarate levels, which triggers a chain reaction that depletes NAD+ and NMN levels in immune cells. This depletion disrupts cellular energy production and increases inflammation, contributing to atherosclerosis (plaque buildup in arteries). The research suggests that maintaining adequate NAD+ and NMN levels may be important for cardiovascular health and controlling inflammation.
