NIGMS’ Small Business Technology Transfer (STTR) program works toward more effective methods for patient screening, diagnosis, and treatment.

Translating lab discoveries into health care products requires large investments of time and resources. Through the STTR Regional Technology Transfer Accelerator Hubs for IDeA States program, NIGMS helps researchers interested in transitioning their discoveries and/or inventions into products. Here are the stories of three researchers working with the XLerator Hub, which funds projects in the southeastern United States and Puerto Rico.

Idhaliz Flores-Caldera, Ph.D., a professor of basic sciences and OB-GYN at Ponce Health Sciences University in Puerto Rico, has studied endometriosis for nearly 20 years. Endometriosis occurs when endometrial tissue, which typically lines the uterus, grows elsewhere in the body. Dr. Flores-Caldera first had the idea for a noninvasive diagnostic test for the disorder about 10 years ago. But it was only when she learned about funding opportunities from the XLerator Hub that she saw a path to validating her preliminary research findings and eventually commercializing her test.

Dr. Flores-Caldera applied for and was accepted into the hub’s proof-of-concept program, Ideas to Products, which funds researchers to flesh out ideas they want to commercialize. “I am very appreciative of how the program has provided me with tools and knowledge about commercializing a product and the process of patenting a product,” she says. “In general, scientists aren’t educated on this important topic.”

Since the virus that causes COVID-19, known as SARS-CoV-2, was first reported in late 2019, scientists have launched hundreds of studies on strategies for diagnosis, prevention, and treatment. To prioritize the most promising vaccine and therapeutics candidates, streamline clinical trials, and coordinate regulatory processes, the National Institutes of Health (NIH) and the Foundation for the NIH have established the Accelerating COVID-19 Therapeutic Interventions and Vaccines (ACTIV) partnership. ACTIV brings together eight government entities, 20 biopharmaceutical companies, and four nonprofit organizations.

The public-private partnership provides infrastructure, subject matter expertise, and funding to efficiently bring the most promising therapeutics and vaccines into clinical trials. Five ACTIV therapeutic trials are underway. NIGMS-supported Institutional Development Award Program Infrastructure for Clinical and Translational Research (IDeA-CTR) networks reach historically underserved areas and populations, which are important participants in such trials.

Since the start of the COVID-19 pandemic, researchers from many areas of biomedical science have worked together to learn how this new disease affects the human body, how to prevent its spread, and how to treat it. Severe cases of COVID-19 and cases of sepsis share many symptoms. Sepsis is the body’s overactive and extreme response to an infection. It’s unpredictable and can progress rapidly. Without prompt treatment, it can lead to tissue damage, organ failure, and death.

Sepsis has similarities with some cases of COVID-19, most likely because the two conditions trigger the same reactions at the cellular level. Researchers have studied these reactions in sepsis for many years.

“When we look back on 2020 and the speed with which progress was made against COVID-19, two features will stand out,” says John Younger, M.D., a member of the NIGMS Advisory Council who recently co-chaired a working group on advancing sepsis research. “The first is how quickly the biotechnology community came together to develop vaccine candidates. The second, and arguably the most immediately impactful, is how caregivers and clinical researchers were able to rapidly refine the care of COVID-19 patients based on decades of experience with sepsis.”

This post highlights a few of the many sepsis researchers supported by NIGMS who are applying their expertise to COVID-19.

Teaching Old Cells New Tricks: Insights Into Molecular-Level Aging

0 comments

When someone mentions aging, you may think of visible changes, like graying hair. Scientists can see signs of aging in cells, too. Understanding how basic cell processes are involved in aging is a first step to help people lead longer, healthier lives. NIGMS-funded researchers are discovering how aging cells change and applying this knowledge to health care.

Discovering the Wisdom of Worms

Aric Rogers, Ph.D., and Jarod Rollins, Ph.D., assistant professors of regenerative biology and medicine at Mount Desert Island (MDI) Biological Laboratory in Bar Harbor, Maine, are investigating aging by studying a tiny roundworm, Caenorhabditis elegans. Researchers often study C. elegans because, though it may seem drastically different from humans, it shares many genes and molecular pathways with us. Plus, its 2- to 3-week lifespan enables researchers to quickly see the effects of genetic or environmental factors on aging.

Drs. Rogers and Rollins investigate how C. elegans expresses genes differently under dietary restriction, enabling it to live longer. Understanding how genes are expressed when organisms live an extended life sheds light on the genetics underlying aging. This information could help researchers develop drugs or behavior modification programs that prolong life and delay the onset of age-related diseases such as heart disease, diabetes, cancer, and dementia.

What Is Computer Modeling and How Does It Work?

Recent news headlines are awash in references to “modeling the spread” and “flattening the curve.” You may have wondered what exactly this means and how it applies to the COVID-19 pandemic. Infectious disease modeling is part of the larger field of computer modeling. This type of research uses computers to simulate and study the behavior of complex systems using mathematics, physics, and computer science. Each model contains many variables that characterize the system being studied. Simulation is done by adjusting each of the variables, alone or in combination, to see how the changes affect the outcomes. Computer modeling is used in a wide array of applications, from weather forecasting, airplane flight simulation, and drug development to infectious disease spread and containment.
