Saving Fat for Lean Times

Humans and all multi-celled organisms, or metazoans, have evolved through millennia into a variety of competing shapes, sizes, and survival strategies. But all metazoans still share lots of intriguing cell biology, including the ability to store excess calories as fat. In fact, many researchers now consider fat-storing cells to be “nutrient sinks,” or good places for the body to stash excess sugars and lipids. Not only can these provide energy needed to survive a future famine, this is a good way to sequester extra molecules that could prove toxic to cells and organs.

Here’s something to think about the next time you skip a meal. Fat-storing cells organize their fat reserves spatially, grouping them into specific pools of lipid types, in order to generate needed energy when food is scarce.

That’s the story behind this striking image taken in a larval fruit fly (Drosophila melanogaster). The image captures fat-storing adipocytes in an organ called a fat body, where a larval fruit fly stores extra nutrients. It’s like the fat tissue in mammals. You can see both large and small lipid droplets (magenta) inside polygon-shaped fat cells, or adipocytes, lined by their plasma membranes (green). But notice that the small lipid droplets are more visibly lined by green, as only these are destined to be saved for later and exported when needed into the fly’s bloodstream.

Working in Mike Henne’s lab at the University of Texas Southwestern Medical Center, Dallas, research associate Rupali Ugrankar discovered how this clever fat-management system works in Drosophila [1]. After either feeding flies high-or-extremely low-calorie diets, Ugrankar used a combination of high-resolution fluorescence confocal microscopy and thin-section transmission electron microscopy to provide a three-dimensional view of adipocytes and their lipid droplets inside.

She observed two distinct sizes of lipid droplets and saw that only the small ones clustered at the cell surface membrane. The adipocytes contorted their membrane inward to grab these small droplets and package them into readily exportable energy bundles.

Ugrankar saw that during times of plenty, a protein machine could fill these small membrane-wrapped fat droplets with lots of triacylglycerol, a high-energy, durable form of fat storage. Their ready access at the surface of the adipocyte allows the fly to balance lipid storage locally with energy release into its blood in times of famine.

Ugrankar’s adeptness at the microscope resulted in this beautiful photo, which was earlier featured in the American Society for Cell Biology’s Green Fluorescent Protein Image and Video Contest. But her work and that of many others help to open a vital window into nutrition science and many critical mechanistic questions about the causes of obesity, insulin resistance, hyperglycemia, and even reduced lifespan.

Such basic research will provide the basis for better therapies to correct these nutrition-related health problems. But the value of basic science must not be forgotten—some of the most important leads could come from a tiny insect in its larval state that shares many aspects of mammalian metabolism.

Happy New Year! I hope everyone finished 2022 with plenty to celebrate, whether it was completing a degree or certification, earning a promotion, attaining a physical fitness goal, or publishing a hard-fought scientific discovery.

If the latter, you are in good company. Last year produced some dazzling discoveries, and the news and editorial staff at the journal Science kept a watchful eye on the most high-impact advances of 2022. In December, the journal released its list of the top 10 advances across the sciences, from astronomy to zoology. In case you missed it, Science selected NASA’s James Webb Space Telescope (JWST) as the 2022 Breakthrough of the Year [1].

This unique space telescope took 20 years to complete, but it has turned out to be time well spent. Positioned 1.5-million-kilometers from Earth, the JWST and its unprecedented high-resolution images of space have unveiled the universe anew for astronomers and wowed millions across the globe checking in online. The telescope’s image stream, beyond its sheer beauty, will advance study of the early Universe, allowing astronomers to discover distant galaxies, explore the early formation of stars, and investigate the possibility of life on other planets.

While the biomedical sciences didn’t take home the top prize, they were well represented among Science’s runner-up breakthroughs. Some of these biomedical top contenders also have benefited, directly or indirectly, from NIH efforts and support. Let’s take a look:

RSV vaccines nearing the finish line: It’s been one of those challenging research marathons. But scientists last year started down the homestretch with the first safe-and-effective vaccine for respiratory syncytial virus (RSV), a leading cause of severe respiratory illness in the very young and the old.

In August, the company Pfizer presented evidence that its experimental RSV vaccine candidate offered protection for those age 60 and up. Later, they showed that the same vaccine, when administered to pregnant women, helped to protect their infants against RSV for six months after birth. Meanwhile, in October, the company GSK announced encouraging results from its late-stage phase III trial of an RSV vaccine in older adults.

As Science noted, the latest clinical progress also shows the power of basic science. For example, researchers have been working with chemically inactivated versions of the virus to develop the vaccine. But these versions have a key viral surface protein that changes its shape after fusing with a cell to start an infection. In this configuration, the protein elicits only weak levels of needed protective antibodies.

Back in 2013, Barney Graham, then with NIH’s National Institute of Allergy and Infectious Diseases (NIAID), and colleagues, solved the problem [2]. Graham’s NIH team discovered a way to lock the protein into its original prefusion state, which the immune system can better detect. This triggers higher levels of potent antibodies, and the discovery kept the science—and the marathon—moving forward.

These latest clinical advances come as RSV and other respiratory viruses, including SARS-CoV-2, the cause of COVID-19, are sending an alarming number of young children to the hospital. The hope is that researchers will cross the finish line this year or next, and we’ll have the first approved RSV vaccine.

Virus fingered as cause of multiple sclerosis: Researchers have long thought that multiple sclerosis, or MS, has a viral cause. Pointing to the right virus with the required high degree of certainty has been the challenge, slowing progress on the treatment front for those in need. As published in Science last January, Alberto Ascherio, Harvard T.H. Chan School of Public Health, Boston, and colleagues produced the strongest evidence yet that MS is caused by the Epstein-Barr virus (EBV), a herpesvirus also known for causing infectious mononucleosis [3].

The link between EBV and MS had long been suspected. But it was difficult to confirm because EBV infections are so widespread, and MS is so disproportionately rare. In the recent study, the NIH-supported researchers collected blood samples every other year from more than 10 million young adults in the U.S. military, including nearly 1,000 who were diagnosed with MS during their service. The evidence showed that the risk of an MS diagnosis increased 32-fold after EBV infection, but it held steady following infection with any other virus. Levels in blood serum of a biomarker for MS neurodegeneration also went up only after an EBV infection, suggesting that the viral illness is a leading cause for MS.

Further evidence came last year from a discovery published in the journal Nature by William Robinson, Stanford University School of Medicine, Stanford, CA, and colleagues. The NIH-supported team found a close resemblance between an EBV protein and one made in the healthy brain and spinal cord [4]. The findings suggest an EBV infection may produce antibodies that mistakenly attack the protective sheath surrounding our nerve cells. Indeed, the study showed that up to one in four people with MS had antibodies that bind both proteins.

This groundbreaking research suggests that an EBV vaccine and/or antiviral drugs that thwart this infection might ultimately prevent or perhaps even cure MS. Of note, NIAID launched last May an early-stage clinical trial for an experimental EBV vaccine at the NIH Clinical Center, Bethesda, MD.

AI Gets Creative: Science’s 2021 Breakthrough of the Year was AI-powered predictions of protein structure. In 2022, AI returned to take another well-deserved bow. This time, Science singled out AI’s now rapidly accelerating entry into once uniquely human attributes, such as artistic expression and scientific discovery.

On the scientific discovery side, Science singled out AI’s continued progress in getting creative with the design of novel proteins for vaccines and myriad other uses. One technique, called “hallucination,” generates new proteins from scratch. Researchers input random amino acid sequences into the computer, and it randomly and continuously mutates them into sequences that other AI tools are confident will fold into stable proteins. This greatly simplifies the process of protein design and frees researchers to focus their efforts on creating a protein with a desired function.

AI research now engages scientists around world, including hundreds of NIH grantees. Taking a broader view of AI, NIH recently launched the Artificial Intelligence/Machine Learning Consortium to Advance Health Equity and Researcher Diversity (AIM-AHEAD) Program. It will help to create greater diversity within the field, which is a must. A lack of diversity could perpetuate harmful biases in how AI is used, how algorithms are developed and trained, and how findings are interpreted to avoid health disparities and inequities for underrepresented communities.

And there you have it, some of the 2022 breakthroughs from Science‘s news and editorial staff. Of course, the highlighted biomedical breakthroughs don’t capture the full picture of research progress. There were many other milestone papers published in 2022 that researchers worldwide will build upon in the months and years ahead to make further progress in their disciplines and, for some, draw the attention of Science’s news and editorial staff. Here’s to another productive year in biomedical research, which the blog will continue to feature and share with you as it unfolds in 2023.

The Chemistry Clicked: Two NIH-Supported Researchers Win 2022 Nobel Prize in Chemistry

Posted on by

Through the years, NIH has supported a total of 169 researchers who have received or shared 101 Nobel Prizes. That’s quite a testament to the world-leading science that NIH pursues and its continued impact on improving human health and well-being.

Those numbers include the news late last week that the 2022 Nobel Prize in Chemistry was shared by two long-time grantees for their work on a transformative scientific approach known as “click chemistry.” This form of chemistry has made it possible for researchers to snap together, like LEGO pieces, molecular building blocks to form hybrid biomolecules, often with easy-to-track imaging agents attached. Not only has click chemistry expanded our ability to explore the molecular underpinnings of a wide range of biological processes, but it has provided us with new tools for developing drugs, diagnostics, and a wide array of “smart” materials.

For K. Barry Sharpless, Scripps Research, La Jolla, CA, October 5, 2022 marked the second time that he’s received an early-morning congratulatory call from The Royal Swedish Academy of Sciences. The first such call came in 2001, when Sharpless got the news that he was a co-winner of the Nobel Prize in Chemistry for his discovery of asymmetric catalytic reactions.

This time around, Sharpless was recognized for his groundbreaking studies in the mid-1990s with click chemistry, a term that he coined himself. His initial work established click chemistry as a fast-and-reliable way to attach molecules of interest in the lab [1]. He and co-recipient Morten Meldal, University of Copenhagen, Denmark, who is not funded by NIH, then independently introduced a copper-catalyzed click that further refined the chemistry and helped popularize it across biology and the material sciences [2,3].

For Carolyn R. Bertozzi of Stanford University, Palo Alto, CA, it is her first Nobel. Bertozzi was recognized for expanding the use of click chemistry with so-called bioorthogonal chemistry, which is a copper-free version of the approach that can be used inside living cells without the risk of metal-associated toxicities [4,5].

Bertozzi’s work has been especially interesting to me because of her focus on glycans, which I’ve studied throughout my career. Glycans are the carbohydrate molecules that coat the surfaces of our cells and most secreted proteins. They are essential to life, and, in higher organisms, play fundamental roles in basic processes such as metabolism, immunity, and cellular communication.

Glycans also remain poorly understood, largely because, until recently, they have been so difficult for basic scientists to study with traditional techniques. That has changed with development of new tools to study glycans and the enzymes that assemble them. My long-time collaborator, Kelly Ten Hagen, a senior investigator at NIH’s National Institute of Dental and Craniofacial Research, and I collaborated with Carolyn on identifying small molecules that inhibit the enzyme responsible for the first step in mucin-type O-glycosylation [6]

In the early 2000s, Bertozzi and her team introduced bioorthogonal chemistry, which enabled researchers to label glycans and visualize them in a range of cells and living organisms. Her team’s pioneering approach quickly became an essential tool in basic science labs around the world that study glycans, leading to a number of stunning discoveries that would have otherwise been difficult or impossible.

For clinical researchers, click chemistry has emerged as a workhorse in drug discovery and the improved targeting of cancer chemotherapies and other small-molecule drugs. The approach also is being used to improve delivery of antibody-based therapies and to create new biomaterials. Meanwhile, in the material sciences, click chemistry has been used to solve a number of problems in working with polymers and to expand their industrial uses.

Click chemistry is an excellent example of how advances in basic science can build the foundation for a wide range of practical applications, including those aimed at improving human health. It also highlights the value of strong, sustained public funding for fundamental research, and NIH is proud to have supported Sharpless continuously since 1975 and Bertozzi since 1999. I send my sincere congratulations to both of these most-deserving scientists.

Understanding Long-Term COVID-19 Symptoms and Enhancing Recovery

RECOVER: Researching COVID to Enhance Recovery. An Initiative Funded by the National Institutes of Health

We are in the third year of the COVID-19 pandemic, and across the world, most restrictions have lifted, and society is trying to get back to “normal.” But for many people—potentially millions globally—there is no getting back to normal just yet.

They are still living with the long-term effects of a COVID-19 infection, known as the post-acute sequelae of SARS-CoV-2 infection (PASC), including Long COVID. These people continue to experience debilitating fatigue, shortness of breath, pain, difficulty sleeping, racing heart rate, exercise intolerance, gastrointestinal and other symptoms, as well as cognitive problems that make it difficult to perform at work or school.

This is a public health issue that is in desperate need of answers. Research is essential to address the many puzzling aspects of Long COVID and guide us to effective responses that protect the nation’s long-term health.

For the past two years, NIH’s National Heart, Lung, and Blood Institute (NHLBI), the National Institute of Allergy and Infectious Diseases (NIAID), and my National Institute of Neurological Disorders and Stroke (NINDS) along with several other NIH institutes and the office of the NIH Director, have been leading NIH’s Researching COVID to Enhance Recovery (RECOVER) initiative, a national research program to understand PASC.

The initiative studies core questions such as why COVID-19 infections can have lingering effects, why new symptoms may develop, and what is the impact of SARS-CoV-2, the virus that causes COVID-19, on other diseases and conditions? Answering these fundamental questions will help to determine the underlying biologic basis of Long COVID. The answers will also help to tell us who is at risk for Long COVID and identify therapies to prevent or treat the condition.

The RECOVER initiative’s wide scope of research is also unprecedented. It is needed because Long COVID is so complex, and history indicates that similar post infectious conditions have defied definitive explanation or effective treatment. Indeed, those experiencing Long COVID report varying symptoms, making it highly unlikely that a single therapy will work for everyone, underscoring the need to pursue multiple therapeutic strategies.

To understand Long COVID fully, hundreds of RECOVER investigators are recruiting more than 17,000 adults (including pregnant people) and more than 18,000 children to take part in cohort studies. Hundreds of enrolling sites have been set up across the country. An autopsy research cohort will also provide further insight into how COVID-19 affects the body’s organs and tissues.

In addition, researchers will analyze electronic health records from millions of people to understand how Long COVID and its symptoms change over time. The RECOVER initiative is also utilizing consistent research protocols across all the study sites. The protocols have been carefully developed with input from patients and advocates, and they are designed to allow for consistent data collection, improve data sharing, and help to accelerate the pace of research.

From the very beginning, people suffering from Long COVID have been our partners in RECOVER. Patients and advocates have contributed important perspectives and provided valuable input into the master protocols and research plans.

Now, with RECOVER underway, individuals with Long COVID, their caregivers, and community members continue to serve a critical role in the Initiative. The National Community Engagement Group (NCEG) has been established to make certain that RECOVER meets the needs of all people affected by Long COVID. The RECOVER Patient and Community Engagement Strategy outlines all the approaches that RECOVER is using to engage with and gather input from individuals impacted by Long COVID.

The NIH recently made more than 40 awards to improve understanding of the underlying biology and pathology of Long COVID. There have already been several important findings published by RECOVER scientists.

For example, in a recent study published in the journal Lancet Digital Health, RECOVER investigators used machine learning to comb through electronic health records to look for signals that may predict whether someone has Long COVID [1]. As new findings, tools, and technologies continue to emerge that help advance our knowledge of the condition, the RECOVER Research Review (R3) Seminar Series will provide a forum for researchers and our partners with up-to-date information about Long COVID research.

It is important to note that post-viral conditions are not a new concept. Many, but not all, of the symptoms reported in Long COVID, including fatigue, post-exertional malaise, chronic musculoskeletal pain, sleep disorders, postural orthostatic tachycardia (POTS), and cognitive issues, overlap with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS).

ME/CFS is a serious disease that can occur following infection and make people profoundly sick for decades. Like Long COVID, ME/CFS is a heterogenous condition that does not affect everybody in the same way, and the knowledge gained through research on Long COVID may also positively impact the understanding, treatment, and prevention of POTS, ME/CFS, and other chronic diseases.

Unlike other post-viral conditions, people who experience Long COVID were all infected by the same virus—albeit different variants—at a similar point in time. This creates a unique opportunity for RECOVER researchers to study post-viral conditions in real-time.

The opportunity enables scientists to study many people simultaneously while they are still infected to monitor their progress and recovery, and to try to understand why some individuals develop ongoing symptoms. A better understanding of the transition from acute to chronic disease may offer an opportunity to intervene, identify who is at risk of the transition, and develop therapies for people who experience symptoms long after the acute infection has resolved.

The RECOVER initiative will soon announce clinical trials, leveraging data from clinicians and patients in which symptom clusters were identified and can be targeted by various interventions. These trials will investigate therapies that are indicated for other non-COVID conditions and novel treatments for Long COVID.

Through extensive collaboration across the multiple NIH institutes and offices that contribute to the RECOVER effort, our hope is critical answers will emerge soon. These answers will help us to recognize the full range of outcomes and needs resulting from PASC and, most important, enable many people to make a full recovery from COVID-19. We are indebted to the over 10,000 subjects who have already enrolled in RECOVER. Their contributions and the hard work of the RECOVER investigators offer hope for the future to the millions still suffering from the pandemic.

Climate Change and Health Initiative to Expand Research, Build Resiliency

Posted on by

Climate change is a global process that affects human health in a variety of complex ways. Wildfires, heat waves, hurricanes, floods, and other climate-related weather events can result in illness, injury, and death. Indirect health threats are cause for concern, too. For example, changes in temperature and rainfall can affect the lifecycle of mosquitoes that transmit diseases such as malaria and dengue fever, thereby paving the way for new outbreaks.

Environmental disruptions worsened by climate change can reduce air quality, diminish water resources, and increase exposure to higher temperatures and pathogens. As a result, we see greater health risks in susceptible individuals such as children, the elderly, the poor, and people with underlying conditions, both in America and around the world.

For decades, the National Institute of Environmental Health Sciences and other NIH institutes and centers (ICs) have advanced important research into how climate change affects health. But expanding knowledge in this area and addressing other key challenges will require much more collaboration. The time is now for an all-hands-on-deck scientific effort—across NIH and the wider biomedical research community—that spans many interconnected disciplines and fields of inquiry.

That is why I am excited to join forces with several other IC directors to launch the NIH Climate Change and Health Initiative. By working together, NIH institutes and centers can harness their technologies, innovative research approaches, and talent to advance the science of climate change and health. Through this timely effort, we will promote resilience in vulnerable communities because our research will help them to understand, prepare for, and recover from climate-related health challenges.

Our Strategic Framework outlines why it is important to go beyond studying the health effects of climate change. We must involve impacted communities in solutions-focused research that empowers them, health care practitioners, and health and social services agencies to reduce climate-related health risks. By generating scientific evidence for public health action, we can use a health equity approach to boost climate resiliency among at-risk groups, whether in the U.S. or low- and middle-income countries.

At the heart of the initiative is a push for transdisciplinary, team-based science that boosts training, research capacity, and community engagement. Our immediate goals are to use existing grant programs to strengthen research infrastructure and enhance communication, internally and externally.

Also, with dedicated support from several ICs and the Office of the Director (OD), NIH is funding a research coordinating center and a community engagement program. The coordinating center will help NIH scientists collaborate and manage data. And the community engagement program will empower underserved populations by encouraging two-way dialogue in which both scientists and community members learn from each other. That inclusive approach will improve research and mitigation efforts and reduce health disparities.

In addition, several Notices of Special Interest are now open for applications. The NIH invites scientists to submit research proposals outlining how they plan either to study the health effects of climate change or develop new technologies to mitigate those effects. Also, with OD support, a Climate and Health Scholars Program will launch later this year. Scientists working on important research will share their expertise and methodologies with the NIH community, spurring opportunities for further collaboration.

Going forward, any additional support from the White House, Congress, and the public will allow NIH to further expand the initiative. For example, we urgently need to test novel interventions for reducing heat stress among agricultural workers and to scale up early-warning systems for climate-related weather events. There is also opportunity to use laboratory-based and clinical methodologies to expand knowledge of how climate factors, such as heat and humidity, affect key cellular systems, including mitochondrial function.

To fill those and other research gaps, we must draw on an array of skill sets and fields of inquiry. Therefore, our Strategic Framework outlines the importance of supporting adaptation research, basic and mechanistic studies, behavioral and social sciences research, data integration, disaster research response, dissemination and implementation science, epidemiology and predictive modeling, exposure and risk assessment, and systems science. Tapping into those areas will help us tackle climate-related health challenges and develop effective solutions.

In recent years, in-depth reports and assessments have provided conclusive evidence that climate change is significantly altering our environment and impacting human health. Although the science of climate change and health has progressed, much work remains. We hope that the Climate Change and Health Initiative expands scientific partnerships and capacity throughout NIH and across the global biomedical and environmental health sciences communities. Greater collaboration will spur new knowledge, interventions, and technologies that help humanity manage the health effects of climate change and strengthen health equity.
