Cellular Garbage Aids Quest for Alzheimer’s Blood Test

Experimental Approach Predicts Future Alzheimer’s Diagnoses

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.

A Look Back at the Legacy of Theodor Kolobow

The IRP has been home to a number of truly remarkable scientists who spent decades making discoveries and developing technologies that would go on to improve the lives of many. One of these giants was Theodor Kolobow, M.D., who passed away in March of last year at age 87. During his many years at the NIH's National Heart, Lung, and Blood Institute (NHLBI), Dr. Kolobow made momentous contributions to the study of our lungs and cardiovascular systems, including advancements in the development of artificial organs and key insights into the biological processes behind acute lung injury. 

Dr. Kolobow's legacy lives on not only through his colleagues' fond memories and his lasting influence on medical practice, but also through the NIH's historical archives. Read on for a tour through Dr. Kolobow's life and career, as can only be told by the Office of NIH History.

Inflammation Cuts Lifeline for Blood-Producing Stem Cells

Discovery Could Lead to New Approaches for Boosting Blood Cell Counts

Much of human biology is a black box — scientists know the key players and the end results, but not how those outcomes come about. Consequently, it remains a mystery why some medications help patients. A new IRP study has cracked open the black box to reveal how high levels of an inflammatory molecule inhibit blood cell production in some individuals and why a particular medicine helps reverse this life-threatening condition.

Ebola Virus: Lessons from a Unique Survivor

Reblogged from The NIH Director's Blog.

Ebola virus (green) is shown on cell surface

There are new reports of an outbreak of Ebola virus disease in the Democratic Republic of Congo. This news comes just two years after international control efforts eventually contained an Ebola outbreak in West Africa, though before control was achieved, more than 11,000 people died—the largest known Ebola outbreak in human history. Many questions remain about why some people die from Ebola and others survive. Now, some answers are beginning to emerge thanks to a new detailed analysis of the immune responses of a unique Ebola survivor, a 34-year-old American health-care worker who was critically ill and cared for at the NIH Special Clinical Studies Unit in 2015.

Exercise Releases Brain-Healthy Protein

Five images of different exercise activities

We all know that exercise is important for a strong and healthy body. Less appreciated is that exercise seems also to be important for a strong and healthy mind, boosting memory and learning, while possibly delaying age-related cognitive decline. How is this so? Researchers have assembled a growing body of evidence that suggests skeletal muscle cells secrete proteins and other factors into the blood during exercise that have a regenerative effect on the brain.

Teen Travels from Jamaica to the NIH for Aplastic Anemia Treatment

Sixteen-year-old Howayne and his Aunt Michelle

Sixteen-year old Howayne McGregor, from Jamaica, suddenly collapsed on his routine walk to school and was rushed to the nearest hospital. After sending his lab results to Dr. Neal Young at the National Institutes of Health (NIH), Howayne received the diagnosis of aplastic anemia, a rare but serious blood disorder in which the body’s bone marrow doesn’t make enough new blood cells.

Enlisting mHealth in the Fight Against River Blindness

When it comes to devising new ways to provide state-of-the art medical care to people living in remote areas of the world, smartphones truly are helping scientists get smarter. For example, an NIH-supported team working in Central Africa recently turned an iPhone into a low-cost video microscope capable of quickly testing to see if people infected with a parasitic worm called Loa loa can safely receive a drug intended to protect them from a different, potentially blinding parasitic disease.
