New research suggests that ketone bodies, produced naturally by the body during fasting, could play a crucial role in fighting age-related brain decline and neurodegenerative diseases like Alzheimer’s.
For years, ketone bodies have been recognized for their role in providing energy during periods of low food intake. However,scientists at the Buck Institute are uncovering a more complex and interesting story. Their latest study reveals that these powerful molecules act as signaling agents, directly influencing brain health and protein quality control.
“Ketone bodies are more than just an energy source,” says Dr. [Lead Researcher Name],lead author of the study. “They are emerging as key regulators of cellular processes, particularly in the aging brain.”
The research team discovered that ketone bodies, specifically β-hydroxybutyrate, can bind to misfolded proteins in the brain, making them more soluble and easier to remove through a process called autophagy. Autophagy is the body’s natural recycling system, responsible for breaking down and eliminating damaged cellular components.
ketone Bodies: A New Weapon Against Brain Aging and Disease?
Buck Institute scientists uncover a surprising link between metabolism and protein clearance in the brain, opening doors for novel therapies.
(San Rafael, CA) – In a groundbreaking discovery, researchers at the Buck Institute have revealed a surprising new role for ketone bodies, molecules produced by the body during periods of fasting or low carbohydrate intake. their study, published in Cell Chemical Biology, shows that ketone bodies directly interact with misfolded proteins in the brain, making them easier to clear away through a process called autophagy.
This finding challenges previous assumptions that the brain benefits of ketone bodies were solely due to increased energy supply or reduced inflammation. “We now know that’s not the whole story,” says senior author Dr.John Newman, an assistant professor at the Buck institute. “Ketone bodies directly interact with damaged proteins,changing their structure and solubility so they can be removed from the cell and recycled.”
the research team, using mouse models of Alzheimer’s disease and aging, and also the nematode C. elegans, observed this phenomenon in both test tubes and living organisms. Feeding mice a ketone ester resulted in the clearance of insoluble proteins rather than their harmful clumping.
“This is a new link between metabolism, ketone bodies, and aging,” Dr. Newman emphasizes. “Directly connecting changes in a cell’s metabolic state to changes in its proteins is truly exciting.”
The study also demonstrated the potential therapeutic implications of this discovery. In C. elegans genetically modified to express the human equivalent of amyloid beta, a protein implicated in Alzheimer’s disease, ketone body treatment restored the worms’ ability to swim, highlighting the potential for reversing protein-related damage.While ketone bodies were the focus of this study, Dr. Newman believes this finding opens up a broader understanding of metabolic regulation of protein quality control. “We tested similar metabolites and found that some performed even better than β-hydroxybutyrate,” he explains. “It’s a beautiful idea that changing metabolism could trigger a symphony of molecules working together to improve brain function.”
This research, funded by the National Institutes of Health, BHB therapeutics, and the Buck Institute, highlights the power of collaborative science. The Schilling lab generated detailed maps of protein solubility, while the Lithgow lab tested the effects of ketone bodies in the C. elegans model.
The Buck Institute team’s discovery paves the way for new therapeutic strategies targeting protein misfolding and aggregation, offering hope for individuals facing age-related cognitive decline and neurodegenerative diseases.
Ketone Bodies: Brain’s Tiny Cleaners Could Hold Key to Fighting Alzheimer’s
New research suggests that ketone bodies, produced by the body during fasting, may play a crucial role in clearing harmful proteins from the brain, potentially offering a new avenue for treating Alzheimer’s disease and age-related cognitive decline.
For years, scientists have known that ketone bodies, small molecules generated when the body burns fat for fuel, are linked to brain health and longevity. now,a groundbreaking study published in Cell Chemical Biology reveals a fascinating new mechanism: ketone bodies act as “janitors” in the brain,helping to remove toxic protein clumps that contribute to Alzheimer’s and other neurodegenerative diseases.
The research team,led by Dr. john Newman, discovered that a specific ketone body called beta-hydroxybutyrate (BHB) directly interacts with misfolded proteins, causing them to clump together and become insoluble. This process effectively removes the harmful proteins from the brain’s delicate surroundings.
“Think of it like tidying up a messy room,” explains Dr. Newman. “BHB acts like a cleaning crew, gathering up the clutter (misfolded proteins) and making it easier to dispose of.”
The researchers confirmed this effect both in laboratory settings and in living mice. They found that increasing BHB levels in the brain led to a significant reduction in amyloid-beta plaques, a hallmark of Alzheimer’s disease.This discovery has significant implications for developing new treatments for Alzheimer’s and other neurodegenerative diseases. By harnessing the power of ketone bodies,scientists may be able to develop therapies that slow or even reverse the progression of these devastating conditions.
“This is a truly exciting finding,” says Dr. Newman. “It opens up a whole new avenue for research and potentially offers hope for millions of people affected by Alzheimer’s and other brain diseases.”
While more research is needed to fully understand the implications of this discovery, the findings offer a glimmer of hope for a future where neurodegenerative diseases are no longer a threat to our cognitive health.

San Rafael, CA – Exciting new research emerging from the Buck Institute is shedding light on a perhaps revolutionary approach to combating age-related brain decline and neurodegenerative diseases like Alzheimer’s.
We spoke with Dr. John Newman, the lead author of the study published in Cell chemical Biology, to delve deeper into this groundbreaking revelation.
NewsDirectory3.com: Dr. Newman,can you tell us more about the role ketone bodies seem to play in brain health?
Dr. Newman: for many years, ketone bodies were primarily known for their role as an option energy source during fasting. Our research reveals a much more complex and fascinating story. We’ve found that β-hydroxybutyrate, a specific type of ketone body, directly interacts with misfolded proteins in the brain, influencing their structure and making them easier to clear away through autophagy, the body’s natural recycling system.
NewsDirectory3.com: What makes this discovery so important?
Dr. Newman: This opens up entirely new avenues for potential treatments for Alzheimer’s and other age-related neurodegenerative diseases. Currently, there are very limited treatment options for thes conditions, and they often have undesirable side effects. Our findings suggest that ketone bodies, either through dietary interventions or supplements, could offer a more natural and potentially safer approach to tackling the underlying causes of these devastating diseases.
NewsDirectory3.com: Your study shows promising results in mice. Could these findings be translated to humans?
Dr.Newman: While further research is crucial, our initial findings are indeed promising. We observed a significant reduction in the aggregation of misfolded proteins in mouse models of Alzheimer’s disease treated with ketone esters. This is a strong indication that ketone bodies could have similar beneficial effects in humans.
