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.

Anthony Covarrubias, PhD Postdoctoral Research Fellow
Dr. Covarrubias is currently exploring the links between inflammation and aging. He joined the Verdin lab in spring 2016 after earning his PhD in the biological sciences program at the Harvard School of Public Health. He has a particular interest in how the innate immune system utilizes nutrients. He came to the Verdin lab because it was among the first to show that endogenous changes in metabolites can affect gene function, and his project in the lab is focused on understanding how metabolites impact the innate immune system during aging. Anthony grew up in Los Angeles and got his undergraduate degree in biochemistry from UCLA. After grad school at Harvard, he is glad to be back on the West Coast. He is new to San Francisco and enjoys exploring the city, visiting breweries, and cheering for the Dodgers when they are in town!
Andrew Cruz PhD Candidate, USC-Buck Biology of Aging Program
Andrew grew up in Long Beach, California, and earned his bachelor’s degree in molecular cell biology from California State University, Long Beach. In his undergraduate lab, he probed structural aspects of Gα-interacting vesicle-associated protein, a signaling protein which plays a role in regulating cell migration and promoting cell survival. Anthony joined the Verdin lab in May 2018. He is interested in the factors that regulate nucleolus size and longevity. Outside of the lab, he enjoys reading, eating at new restaurants, and learning new songs on the ukulele.
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.
