  • Rare Genetic Variation May Protect Against Alzheimer’s Disease

    The APOEε4 gene variant is a major genetic risk factor for developing Alzheimer's disease (AD) later in life. People with two copies of this variant are almost certain to develop the disease, yet some people with this variant do not get dementia and scientists are still figuring out why. In a recent study,  a team of investigators led by Drs. Badri Vardarajan, Caghan Kizil, and Richard Mayeux analyzed the genetic data of 3,500 individuals from over 700 families of different ethnic backgrounds. Their findings, published in Acta Neuropathologica and highlighted in the CUIMC Newsroom, revealed 510 genetic variants that might protect against AD. These protective variants mainly affect the genes involved with the brain's blood barrier system. Notably, one specific variant in the fibronectin (FN1) gene stood out. Research involving over 11,000 participants from Columbia, Stanford, and Washington universities showed that this FN1 variant can reduce the risk of AD by 71% and delay its onset by about four years. It does this by reducing the buildup of certain proteins and inflammation in the brain's blood vessels. Experiments with zebrafish and human brain studies after death showed that losing FN1 function helps clear harmful amyloid proteins and improves the activity of immune cells in the brain. This groundbreaking research opens up new possibilities for treating Alzheimer's disease by targeting the brain's blood vessels.

  • Study Shows a Healthy Diet is Linked with a Slower Pace of Aging, Reduced Dementia Risk

    March 14, 2024

    A healthier diet is associated with a reduced dementia risk and slower pace of aging, according to a new study at Columbia University Mailman School of Public Health and The Robert Butler Columbia Aging Center. The findings show that a diet-dementia association was at least partially facilitated by multi-system processes of aging. While literature had suggested that people who followed a healthy diet experienced a slowdown in the processes of biological aging and were less likely to develop dementia, until now the biological mechanism of this protection was not well understood. The results are published in the Annals of Neurology.

    “We have some strong evidence that a healthy diet can protect against dementia,” said Yian Gu, PhD, associate professor of Neurological Sciences at Columbia Vagelos College of Physicians and Surgeons and head of the Mailman School Neuroepidemiology Unit, and the other senior author of the study, “But the mechanism of this protection is not well understood.” Past research linked both diet and dementia risk to an accelerated pace of biological aging.

  • James Noble, MD, MS Inducted into the Academy of Community and Public Service

    February 7, 2024

    Associate Professor of Neurology James Noble, MD, MS, along with nine other faculty members from Columbia University Irving Medical Center, was recently inducted into the Academy of Community and Public Service (ACPS) in recognition of his exceptional efforts to promote health, well-being, and overall quality of life in the local communities of upper Manhattan, as well as nationally and globally.

    At the event, Professor of Neurology and Vice Dean of Community Health Dr. Olajide Williams, a co-chair of ACPS, said of the awardees, “The work and dedication to community and public service of the people here today are nothing short of inspiring. I’m a big believer in inspiration, because inspiration is what sparks imagination, and imagination sparks innovation. And it’s innovation that is truly going to move us to a place where we can finally say, ‘out of many, we are one.’” [read more]

  • A Multidisciplinary Approach to Neurological Care Driven by Diverse Interests

    February 7, 2024

    5 Questions With Dr. James Noble

    Dr. James Noble isn’t one for being boxed in. The neurologist and neuroepidemiologist at NewYork-Presbyterian/Columbia is an expert in dementia, but a sampling of his work reflects his broad clinical and research interests: He’s investigating the link between periodontal disease and Alzheimer’s disease. He’s developed a prototype for a device that helps diagnose concussions in real time. He’s researching how hip-hop can be used in health education and cofounded a nonprofit, Arts & Minds, to support the power of visual arts in improving wellness for dementia patients and caretakers.

    These seemingly disparate projects all tie together for Dr. Noble. “First, I’m passionate about each of them. They tend to reflect a problem that I’m trying to solve or a question that I’m trying to answer,” he says. “And second, if I can prove in a methodical and scientifically rigorous way that all these things can make a difference for people, I believe they are worth doing.” [read more]

  • Fishing for Insights into Human Disease

    January 18, 2024
    By Gary Goldenberg

    Over the years, zebrafish (and to a lesser extent killifish) have become an important experimental model in biomedical research, thanks to their genetic similarity to humans, transparent embryos, rapid development, and regenerative abilities, among other features. Columbia researchers are using these finned wonders to gain insights into human health and disease. Caghan Kizil, PhD, MSc, Associate Professor of Neurological Sciences in Neurology and in the Taub Institute, uses zebrafish in his research on Alzheimer's disease. [read more about how other Columbia researchers are using zebrafish in their work]

    Can zebrafish teach us how to regenerate neurons?
    No one would argue that zebrafish, whose brains are the size of a sesame seed, are smarter than humans. But these tiny aquatic animals can do a few tricks that humans cannot, such as growing scores of new brain neurons in response to neurological pathologies such as Alzheimer’s disease or injury, even well into adulthood. In contrast, once past childhood, humans can manage to regenerate only a smattering of neurons, a rate that declines even more with disease.

    Using zebrafish as a model organism, Caghan Kizil, PhD, associate professor of neurological sciences (in neurology and in the Taub Institute) at the Vagelos College of Physicians and Surgeons, is gaining new insights into the molecular mechanisms that underlie neuronal regeneration, or neurogenesis.

    “The beauty of zebrafish is that we can get human-relevant experimental results in weeks instead of months or years with other animal models,” adds Kizil. “We can even get these fish to perform memory tests to investigate the cognitive consequences of therapeutic interventions for neurological diseases.”

    Thus far, Kizil’s studies have revealed a key molecule (nerve growth factor receptor) that controls nerve regeneration in zebrafish. The same molecule appears to be active in humans during early development but not in Alzheimer’s patients.

    “If we could kickstart neurogenesis in humans, we might be able to slow the progression of Alzheimer’s by enhancing the brain’s resilience,” says Kizil. His team has already identified two potential targets for drug therapy. The researchers are designing compounds to selectively hit those targets, which they will evaluate in zebrafish.
