New Innovator Award Recognizes High-Risk, High-Reward Project to Measure Environmental Impacts on 亚洲自慰视频

Sophia Friesen

Our environment has a profound effect on our health, but the specifics of those effects can vary widely from person to person. Wildfire smoke that one person might find merely annoying could be debilitating to another. And the variable health consequences of environmental exposures aren鈥檛 always immediate or obvious, even when serious.
 
But what if a doctor could tell you how the air quality where you live impacts your lungs, how your diet changes your gut health, and how a plethora of other environmental factors affect other organs throughout your body鈥攁ll with a single blood draw?

It might sound like science fiction, and it is鈥攆or now. But is trying to make it a reality, now powered by a New Innovator Award through the National Institutes of 亚洲自慰视频 Common Fund鈥檚 High-Risk, High-Reward Research program. Lu, an assistant professor of molecular pharmaceutics in the 亚洲自慰视频 of Utah College of Pharmacy, received this prestigious award, which is granted to early-career researchers pursuing exceptionally creative and innovative projects with the potential for broad societal impact.
 
鈥淒r. Lu鈥檚 science is highly innovative and can lead to a better understanding of how our environment is impacting our bodies and health,鈥 says Rachel Hess, MD, associate vice president for research at U of U 亚洲自慰视频. 鈥淲e are thrilled that this high-risk, high-reward work has been recognized by the National Institutes of 亚洲自慰视频 and cannot wait to see where Dr. Lu鈥檚 research leads.鈥

Decoding microscopic messages

Lu鈥檚 research takes advantage of a biological phenomenon that is increasingly coming into the spotlight: tiny bubbles called extracellular vesicles (EVs). Cells throughout your body release these bubbles into the bloodstream, containing a wide array of biological molecules that vary depending on what kind of cell they came from鈥攍iver cells, brain cells, or so forth. It鈥檚 as if every cell in your body is throwing thousands of messages in a bottle into the ocean of your bloodstream, every day.
 
What those messages mean鈥攊f they mean anything鈥攊s largely unknown. But Lu thinks they could provide valuable hints about their senders, allowing researchers to understand how the environment is impacting organ systems without anything more invasive than a blood draw.
 
鈥淲hat if we could monitor the health impact of environmental exposures with organ-level accuracy across large populations?鈥 Lu asks. She intends to use EVs to enable precise and high-throughput health analysis on multiple scales.
 
Lu and her team aim to develop multiple new tools to detect and understand EVs. One of the tools will separate out single EVs from a blood sample and analyze the molecules in each one. (It鈥檚 the equivalent of reading a single message in a bottle in detail.) Other tools will help piece together fragmentary information from many EVs into a coherent picture of organ health and look at large numbers of EVs in aggregate.
 
Lu鈥檚 first target is to study EVs coming from the lungs to understand lung health, including how lung health is affected by air quality and other environmental exposures. But if her system works, it could be equally useful for studying how other exposures affect every other organ system. A key advantage of the project is its scalability; a blood draw is much faster, simpler, and safer than a tissue biopsy. In theory, a single blood sample could provide information about every organ in the body.
 
Lu hopes that the tools her team builds will shed new light on how the environment affects health. 鈥淥ur long-term vision is an extracellular vesicle tricorder that provides a new lens for understanding human health and reveals hidden threats among everyday exposures,鈥 she says.
 
The NIH issued 40 New Innovator awards nationwide in 2024, as well as eight Pioneer awards, seven Transformative Research awards, and 12 Early Independence awards through the High-Risk, High-Reward Research program.
 
鈥淭he HRHR program champions exceptionally bold and innovative science that pushes the boundaries of biomedical and behavioral research,鈥 said Tara A. Schwetz, Ph.D., NIH Deputy Director for Program Coordination, Planning, and Strategic Initiatives and Director of the Division of Program Coordination, Planning, and Strategic Initiatives, which oversees the NIH Common Fund. 鈥淭he groundbreaking science pursued by these researchers is poised to have a broad impact on human health.鈥
