Microbial Products Affect the Hallmarks Of Aging: 1) Mitochondrial Function

The Hallmarks of Aging are well established, but what is less discussed is the impact of microbes and/or microbial products. The bacterial metabolite, LPS, increases during aging, and it negatively impacts mitochondrial function, thereby demonstrating a role for microbial products on one of the Hallmarks of Aging, mitochondrial dysfunction.

LPS Increases During Aging: Besides Calorie Restriction, What Else Can Reduce It?

LPS increases during aging, which may explain the age-related increase for CD38 and decreased NAD+. LPS is decreased on a calorie restricted diet, but what else can reduce it? In this video, I present evidence for intestinal alkaline phosphatase’s (IAP) role on LPS, and posit that interventions that increase IAP may be an important approach for increasing NAD+.
