Experimental Treatment Curbs Autoimmune Eye Disease in Mice
Tuesday, August 11, 2020
Our cells produce a wide range of chemicals necessary for good health, but when they cannot manufacture enough of these substances, scientists can use cells cultivated in their labs to pick up the slack. In a promising example of this approach, IRP scientists stimulated lab-grown immune cells to produce tiny bundles of an important anti-inflammatory molecule and used those packages to successfully treat a potentially blinding autoimmune disease in mice.
High-Tech Nicotine Delivery Technologies Raise Risk for Relapse
Tuesday, July 28, 2020
Scholars have long debated about the use of nuclear power, gene editing, and many other technologies that can have both positive and negative effects on society. Recently, researchers have been having similar discussions about the public health effects of electronic cigarettes. Adding to this debate, a new NIH study highlights a concerning drawback of e-cigarettes by showing they increase the risk that people who have successfully quit smoking will resume using tobacco products.
Mouse Study Illuminates Potential Mechanism Behind Mood and Anxiety Disorders
Tuesday, July 14, 2020
Millions of Americans suffered from depression and anxiety even before COVID-19 began upending their lives. To make matters worse, the stresses of living through a pandemic might not only worsen mental health but could also wreak havoc on the brain itself. New IRP research has found that psychological stress damages blood vessels in the brains of mice and dramatically alters the behavior of genes in certain blood vessel cells.
IRP Study Examines Overlooked Contributor to Racial Health Disparities
Tuesday, June 23, 2020
Recent news coverage of the deaths of George Floyd, Ahmaud Arbery, and Breonna Taylor, along with statistics reporting startlingly disproportionate death rates among black Americans infected with COVID-19, have made it clear that racial biases can be a matter of life and death. Meanwhile, it can be easy to overlook other, more subtle ways that discrimination can affect health, such as new IRP research that links instances of discrimination to poor sleep.
Mouse Study Supports Potential of Ketone-Elevating Treatment
Tuesday, June 2, 2020
Whether from candy, soda, or fruit, sugar is the preferred source of sustenance for many people, and also for their brains. However, in patients with Alzheimer's disease, brain cells are less capable of turning sugar into energy. New IRP research provides evidence that this problem and the cognitive symptoms it causes could be partially solved by providing the brain with an alternative fuel.
Scientists Parse Wide-Ranging Effects of Endometrial Cancer Mutation
Tuesday, May 12, 2020
The so-called ‘butterfly effect’ supposes that a butterfly flapping its wings in Brazil can cause a tornado in Texas. While the jury is still out on insect-induced natural disasters, it is clear that a single genetic mutation can have wide-ranging and unexpected consequences throughout a cell. By examining the ripple effects caused by changes in a particular gene, IRP researchers have identified a potential treatment target for a particularly deadly variety of cancer.
Cells From Bone Marrow Calm Damaging Immune Response
Tuesday, April 28, 2020
In patients with the inflammatory disease sarcoidosis, the body’s own immune cells rampage around the body like The Incredible Hulk set loose in a city, attacking both harmful pathogens and our own tissues. However, just like the Black Widow can calm The Hulk down and return him to human form in the Avengers films, cells isolated from our bone marrow may be able to change certain immune cells from a damaging state to a benign one, according to new IRP research.
Study Suggests New Treatment Strategy for Increasingly Common Disease
Monday, April 6, 2020
In the classic sci-fi film Alien, the protagonist attempts to destroy the titular monster by triggering the self-destruct mechanism on her spaceship. Our cells also sometimes need to destroy themselves in order to circumvent threats like cancer, but uncontrolled cell death can lead to disease. New IRP research suggests that preventing certain cells in the pancreas from tripping their self-destruct switch could help relieve the symptoms of type 2 diabetes.
Mouse Study Suggests Approach to Protect Cancer Patients’ Hearing
Tuesday, March 24, 2020
The internet is filled with lists of ‘life hacks’ that provide instructions on how to re-purpose common items, from turning glass jars into flower vases to using sticky notes to remove dust or crumbs from the crevices of a computer keyboard. On occasion, this kind of inventive spirit can be used to improve human health as well. IRP researchers have found evidence in mice that a statin medication originally created to lower cholesterol might also reduce hearing loss caused by a common cancer therapy.
Narrower Research Focus Could Aid Treatment for Autoimmune Diseases
Tuesday, March 10, 2020
Police pursuing a dangerous criminal rely on witness descriptions of the suspect’s specific traits — height, weight, hair color, tattoos — to pick out the perpetrator from a vast population of mostly innocent individuals. Scientists can likewise distinguish between highly similar cell types using cutting-edge laboratory procedures. Using such techniques, IRP researchers have identified a particular variety of cell in a specific stage of its life cycle as a primary culprit behind the autoimmune disease known as lupus.
