Verdin Lab

Eric Verdin, MD

President and Chief Executive Officer, Professor

Understanding epigenetic regulators of the aging process.

Lab focus

The Verdin lab studies the relationship between aging and the immune system. Aging is associated with defects in the adaptive immune system and with a state of chronic activation of the innate immune system (chronic inflammation).

We study how immune aging is regulated by nutrition. We have demonstrated how changes in the relative abundance of key cellular metabolites such as NAD+, acetylcoenzyme A, and the ketone body beta-hydroxybutyrate fluctuate under different nutritional conditions (obesity, calorie restriction, fasting, time-restricted feeding, ketogenic diet) and how this influences immune responses. We are working on key enzymes regulated by these metabolites. These include sirtuins (NAD+), histone acetyltransferases (acetylcoenzyme A), and histone deacetylases (HDACs).

We utilize worm, mice, and human model systems (including stem cells and iPSCs) to define how nutrients influence immune responses during aging. We are also studying how HIV infection induces a state of chronic inflammation and immune activation and how this induces accelerated aging in patients infected with HIV.

Why it matters

We believe chronic inflammation represents a key unifying factor underpinning the development of the chronic diseases of aging, including neurodegeneration (Parkinson’s and Alzheimer’s), cancer, type 2 diabetes, and atherosclerosis (heart attack and stroke). We are intrigued by possible connections between senescence, leaky gut, and innate immune activation. A better understanding of the mechanisms leading to the chronic inflammation associated with aging should provide novel therapeutic targets and potential interventions against human aging.

 

Science is showing that while chronological aging is inevitable, biological aging is malleable. There's a part of it that you can fight, and we are getting closer and closer to winning that fight.
