Experimental Approach Predicts Future Alzheimer’s Diagnoses
Tuesday, October 15, 2019
If you looked through my garbage, you would probably find a litany of apple cores (my favorite fruit) and a couple fundraising requests from my alma mater. Similarly, scientists can learn a lot about what is going on in cells by examining their trash. IRP researchers recently developed a blood test that may be able to predict Alzheimer’s disease years before the onset of symptoms by examining packages of waste products from neurons.
Five Questions with Dr. Catherine Bushnell

Yoga is all the rage these days, with millions of people taking part in the practice for relaxation, meditation, and increasing flexibility and muscle strength. However, the benefits of yoga go beyond what most might think. In fact, the mind-body practice of yoga could have a significant impact on the lives of those living with chronic pain, a condition that affects tens of millions of Americans.
In the past, doctors often prescribed opioids to treat chronic pain. However, research has shown that people with chronic pain have anatomical and neurochemical alterations in the brain that make them less responsive to opioids. In addition, both the medical and political systems are currently contending with a public health crisis stemming from the over-use of opioid pain medications. As a result, researchers have been working to identify ways to better manage chronic pain, particularly without the use of medication.
Disrupting Itch-Related Process Could Relieve Relentless Itching

For most people, the arrival of spring time means more time spent outdoors — and greater exposure to nuisances like biting insects and poison ivy that make us itch. New IRP research has revealed a detailed picture of how a particular type of cell causes itching, findings that may ultimately help researchers develop treatments for disorders that cause severe and long-lasting itch.
New Technique Overcomes Major Obstacle to Stem-Cell-Based Treatments

Your brain cells need plenty of oxygen and nutrients to survive — that is, unless you’re a hibernating ground squirrel. By tapping into the cellular process that keeps these animals’ brains healthy during the long winter months, IRP scientists have discovered a way to increase the survival of neuron-producing stem cells implanted into the brain after a stroke, a development that could one day dramatically improve stroke treatment.

Science is a process of trial and error. Most successful research publications are preceded by at least a few false starts and perhaps weeks or even months of tinkering to get experiments to work. For IRP senior investigator Carson Chow, Ph.D., this process of testing and throwing out one potential solution after another is an essential part of his research, so much so that he may go through thousands of iterations before arriving at one that works. However, rather than test each approach himself, he leverages the IRP’s considerable computing power to considerably accelerate the process of sorting the wheat from the chaff.

While many people can easily stop after a beer or two, for others one drink begets many more, ultimately leading to an addiction that drives continuously increasing alcohol consumption over time. New IRP research has identified a specific type of neuronal receptor involved in the development of alcohol dependence in mice, suggesting a possible approach to curbing problematic drinking behaviors in humans addicted to alcohol.

Most people experience anxiety at some point in their lives, whether it’s pre-speech jitters or sweaty palms when their plane takes off. While mild feelings of nervousness are completely normal and can even be beneficial, anxiety can also have negative repercussions if it causes somebody to completely avoid situations like social encounters or taking a flight to visit distant family.

Jason Mazique, who is currently a freshman at Williams College in Williamstown, Massachusetts, spent his 2017 summer working in the lab of NIH IRP Senior Investigator Dr. Harish Pant. During his time at the NIH, Mazique investigated how a particular protein affects neurons in the brain, with implications for neurological conditions like ALS and Alzheimer’s disease

Studying the neural control of behavior is a challenge. Researchers must consider an animal’s environment, past experiences, and motivations. Work in relatively simple organisms, for example the invertebrate C. elegans, has teased apart the neural circuitry of highly stereotyped behaviors, like foraging. But in mammals, very little is known, “and that’s surprising given just how important behaviors like this are,” said Dr. Eric Horstick, who studies the molecular mechanisms underlying animal behavior.

This year, members of the National Academy of Medicine elected four NIH Intramural researchers to their ranks, one of the highest honors in science. Learn a bit about each of their research and follow the links to their IRP profiles for more information.
