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.

  • Nicolas Andrews, PhD  Senior Staff Scientist

    Nicolas earned his PhD in immunology from Emory University. There, he used a model of chronic viral infection to investigate the role of initial viral dose and early inflammatory signals in shaping the quality and magnitude of virus-specific T cell responses. His subsequent research encompassed topics as diverse as cancer biology, autoimmunity, recombinant antibody technology, and the role of chromatin structure in the DNA damage response. After a brief period in academia, Nicolas joined the Verdin lab in the summer of 2019 to study mechanisms that establish and maintain HIV latency. Additionally, he will investigate mechanisms that contribute to the accelerated aging phenotype of HIV-infected patients. When not in the lab, Nicolas enjoys trail running and exploring the backroads of California from the seat of a motorcycle.

  • Vicki Hirth  Lab Technician

  • Herb Kasler, PhD  Staff Scientist, Flow Cytometry Core Director

    Dr. Kasler did his undergraduate work in biology at Duke University and earned his PhD in immunology from University of California, Berkeley, working on the regulation of cell death in T-cell development in the laboratory of Dr. Astar Winoto. Since joining the Verdin lab, his main area of focus has been elucidating the immunobiology of histone deacetylase 7 (HDAC7), an epigenetic regulator with an essential role in the maintenance of immune self-tolerance. With other members of the immunology group, he is working to define the molecular mechanisms whereby the TCR-dependent nuclear export of HDAC7 mediates both negative thymic selection and the differentiation of agonist-selected innate-like T-cell populations. By understanding the important role of HDAC7 in T-cell development, he hopes to gain new insights into the regulation of immune self-tolerance and also to identify novel molecular pathways that can be targeted in autoimmune disease. When he is not pushing back the frontier of human knowledge one miniprep at a time, he likes to cook fabulous food for his friends and family, hike through the many splendid landscapes surrounding the Bay Area, and play at being a suburban farmer.

  • Ik-Jung Kim, PhD  Postdoctoral Research Scholar

    Dr. Kim is originally from South Korea. After earning an undergraduate and a master’s degree at Sogang university, he moved to the United States for a PhD training in the field of cellular microbiology. At the University of Illinois at Urbana-Champaign, he worked in Dr. Steven Blanke’s lab to study human infection with Helicobacter pylori, which he found manipulates host metabolism, resulting in a global metabolic shift from a biosynthetic to a catabolic state. As growing older, his deep interest in human metabolism stretched to aging biology and finally drew him to the Buck Institute. Since joining Verdin lab in February, 2019, he strive to understand how the levels of NAD+, a central metabolite involved in energy production and healthspan, are systemically regulated, using in vitro and in vivo models. Outside of the lab, he can be found exploring the beautiful nature in Northern California, or, pampering his hedgehog pets.
