Interdisciplinary Approaches to Addiction Research

By bringing together researchers from different disciplines, the IRP tackles some of the biggest questions in science from multiple angles. Here are just a few examples of the many diverse approaches that Intramural scientists take to better understand addiction.

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.

Tracing the Neural Circuitry of Appetite

Reblogged from the NIH Director's Blog. Originally posted by Dr. Francis Collins, NIH Director, on May 5, 2015.

If you’ve ever skipped meals for a whole day or gone on a strict, low-calorie diet, you know just how powerful the feeling of hunger can be. Your stomach may growl and rumble, but, ultimately, it’s your brain that signals when to start eating—and when to stop. So, learning more about the brain’s complex role in controlling appetite is crucial to efforts to develop better ways of helping the millions of Americans afflicted with obesity.

From Mitochondria to Behavior

Mitochondria are dynamic cellular organelles involved in ATP synthesis and in apoptotic mechanisms (programmed cell death). However, in addition to these classically known functions, recent studies at the NIH have deciphered another intriguing role for mitochondria in the development and plasticity of neurons.

The Power of Vaccines Research

Long recognized as essential to global health, vaccines protect individuals and populations from contagion and the reappearance of eradicated diseases. Vaccination against deadly diseases prevents two to three million deaths worldwide every year, and there are significant economic benefits as well. In the United States, every dollar spent on the routine childhood immunization program saves society more than $16 in future costs.

How Asking a Very Basic Research Question Led Us to a Model For At Least 3 Diseases

When I started this project, it was not my objective to develop a model for any specific disease, nor did I even suspect that the ultimate result would be some insight into autoimmune disease. The basic research question I was asking was why there are sequences in the 3’ untranslated region of the interferon-gamma mRNA that are more highly conserved than the coding region of the gene.

Ebola: Scientific Research in Search of a Public Health Solution

As the international community continues to seek collaborative approaches to contain and eradicate the current Ebola outbreak in West Africa, we are reminded that these efforts are also an investment in our own public health. Only by defeating a virus at its source can we prevent infectious diseases from spreading to other countries.

Let There Be Light!

Optogenetics, a new technology used to control brain activity with light, has revolutionized the field of neuroscience in the past decade. The combination of two powerful tools, genetics and optics, has provided both temporal and spatial acuity in understanding how the brain works in response to sensory and motor cues in the environment. At the recent NIH Research Festival symposium titled “Optogenetic approaches to investigating the nervous system,” fellows and scientists from the NIH community presented their research encompassing topics that make use of this approach to study different systems.
