(Press-News.org) UVA Health lung researchers are developing a promising approach to detecting patients at risk of interstitial lung disease (ILD), an increasingly common condition that is a leading reason for lung transplants. The approach could accelerate the development of new and better treatments with more tolerable side effects than existing options.
The UVA scientists have already discovered biological indicators in the blood – “biomarkers” – that can predict the survival chances of patients with ILD. But the researchers, led by John S. Kim, MD, believe these types of biomarkers can be used for far more: The scientists are aiming to determine if biomarkers can identify people who have not yet developed ILD but will go on to do so. They also hope to map out the molecular hallmarks of early and late-stage ILD to better understand the condition and how it develops, as well as to find ways to prevent it.
“Oftentimes when patients are diagnosed with interstitial lung disease, they already have a lot of damage to their lungs that may not recover and limits how effective treatments can be,” said Kim, of UVA Health’s Division of Pulmonary and Critical Care. “Our goal is to identify treatments that can prevent ILD, and an important step to do this is identify adults at risk of developing this disease in the future.”
Understanding Interstitial Lung Disease
ILD is a group of chronic respiratory conditions that cause inflammation and scarring in the lung tissue. The most common type is idiopathic pulmonary fibrosis (IPF), the cause of which is not entirely understood. Some forms of ILD progress faster than others, but some are life-threatening, and there is no cure. Approximately a third of all lung transplants each year go to patients with ILD.
There are drugs available that can slow the progression of IPF, but these drugs can have side effects, such as affecting liver function, that can leave patients unable to take them. Many patients also suffer from gastrointestinal issues such as nausea, vomiting and diarrhea, so new and better treatments are much needed.
Kim and colleagues recently published a research study in the American Journal of Respiratory and Critical Care Medicine that identified several plasma protein biomarkers that were dassociate with new-onset ILD. Notably, some of these proteins were highly expressed in lung tissue of patients with ILD. Kim and his collaborators hope to build off this published work and help doctors better understand ILD and IPF and find new ways to treat the conditions. The researchers have received a five-year grant from the National Institutes of Health’s National Heart, Lung and Blood Institute to take the next steps in their research, which they hope will ultimately allow doctors to enroll people at risk of developing ILD in preventative clinical trials.
“We aim to identify blood biomarkers that predict both the development of ILD and survival in patients with disease,” said Kim, of the UVA School of Medicine’s Department of Medicine. “We hope these biomarkers can complement other tools like lung imaging and genomics to identify adults at higher risk of developing ILD, which will be crucial to developing treatments aimed at preventing this disease.”
Findings Published
Kim and his colleagues have described their biomarker findings in a scientific paper in the American Journal of Respiratory and Critical Care Medicine. The research team consisted of Kim, Catherine L. Debban, Daniel Guzman, Riley T. Hannan, Mary Salvatore, Claire McGroder, David Zhang, Anna J. Podolanczuk, Daniel A. Duprez, Shwu-Fan Ma, Yong Huang, Jeffrey M. Sturek, Stephen S. Rich, Jerome I. Rotter, Rajat Deo, Ruth F Dubin, Janelle Vu Pugashetti, Janelle Vu Pugashetti, Jennifer M Wang, Jennifer M.

Hoffman, Christine Kim Garcia, Russell P. Bowler, Peter Ganz, R. Graham Barr and Ani Manichaikul.
A full list of funding sources for the research and the Multi-Ethnic Study of Atherosclerosis (MESA) Lung Study and Subpopulations and Intermediate Outcome Measures in COPD (SPIROMICS) the scientists used to conduct the research is included in the paper.
The next steps in the UVA Health research is being funded by NHLBI grant R01HL176659-01A1.

How can we know when curing cancer causes myocarditis?
2025-10-10
Treatments for cancer are continuously improving, but they can still cause debilitating, even fatal, side effects. Immune checkpoint inhibitors, or ICIs, have revolutionized cancer therapy, yet their use can trigger a rare but deadly side effect that affects the heart: myocarditis. ICI-related myocarditis has a mortality of up to 40%.
The adverse side effects caused by ICIs are immune-related. The immune system becomes hyperactive and attacks tissue that is healthy, not cancerous. In ICI-related myocarditis, ...

An acoustofluidic device for sample preparation and detection of small extracellular vesicles
2025-10-10
Recent research has achieved significant advances in acoustofluidic technologies for efficient isolation and biomarker-specific detection of small extracellular vesicles (sEVs). Nevertheless, rapid and high-sensitivity analysis of low-volume clinical samples remains challenging, often requiring multi-step preprocessing and bulky instrumentation. By integrating sharp-edge microstructures with acoustically induced vortices, we enable size-selective concentration of target-bound complexes for immediate fluorescence readout. "The acoustofluidic chip leverages localized acoustic streaming to spatially separate microbead-sEV conjugates from ...

2025-10-10
Cancer remains a leading cause of global morbidity and mortality. Traditional therapies like chemotherapy and radiotherapy are often limited by their lack of specificity, leading to systemic toxicity and the emergence of drug resistance. Nanoparticles, with dimensions ranging from 1 to 100 nm, offer a sophisticated solution. Their unique physicochemical properties allow them to navigate biological barriers and can be engineered for active targeting (e.g., using ligands for overexpressed cancer cell receptors) or passive targeting (exploiting the Enhanced Permeability and Retention effect of tumor vasculature). The cellular uptake ...

Now, researchers report in ACS Applied Materials & Interfaces that they have created a paper-thin LED that gives off a warm, sun-like glow. The LEDs could light up the next generation of phone and computer screens and other light sources while helping users avoid disruptions to their sleep patterns.
“This work demonstrates the feasibility of ultra-thin, large-area quantum dot LEDs that closely match the solar spectrum,” says Xianghua Wang, a corresponding author of the study. “These devices could enable next-generation eye-friendly ...
Transnational electoral participation of undocumented Mexican immigrants in the US
2025-10-10
The global increase in migration—with approximately 3.6% of the global population living as expatriates—has resulted in many countries extending external voting rights to their overseas citizens. This has prompted scholarly interest in understanding the electoral participation of immigrants in their countries of origin. However, most research has focused on the factors that drive the provision of external voting rights to expatriates rather than the extent to which these rights are exercised. Furthermore, prior research has largely overlooked the political behavior of undocumented immigrants, who constitute a significant share of the immigrant population, especially in the United ...

Freely levitating rotor spins out ultraprecise sensors for classical and quantum physics
2025-10-10
Levitation has long been pursued by stage magicians and physicists alike. For audiences, the sight of objects floating midair is wondrous. For scientists, it’s a powerful way of isolating objects from external disturbances. This is particularly useful in case of rotors, as their torque and angular momentum, used to measure gravity, gas pressure, momentum, among other phenomena in both classical and quantum physics, can be strongly influenced by friction. Freely suspending the rotor could drastically reduce these disturbances – and now, researchers from the Okinawa Institute of Science and Technology (OIST) have designed, created, and analyzed such a macroscopic device, bringing ...
‘Chinese lantern’ structure shifts into more than a dozen shapes for various applications
2025-10-10
Researchers have created a polymer “Chinese lantern” that can snap into more than a dozen curved, three-dimensional shapes by compressing or twisting the original structure. This rapid shape-shifting behavior can be controlled remotely using a magnetic field, allowing the structure to be used for a variety of applications.
The basic lantern object is made by cutting a polymer sheet into a diamond-like parallelogram shape, then cutting a row of parallel lines across the center of each sheet. This creates a row of identical ribbons that is connected by a solid ...
Towards light-controlled electronic components
2025-10-10
In the future, could our mobile phones and internet data operate using light rather than just electricity? Now, for the first time, an international research team led by CNRS researchers1 has discovered how to generate an electron gas, found for example in LED screens, by illuminating a material made up of layers of oxides2. When the light is switched off, the gas disappears. This phenomenon, which lies at the interface of optics and electronics, paves the way for numerous applications in electronics, spintronics and quantum computing. It is described in an article to be published on 10 October in the journal Nature Materials.
Electronic components that can be controlled by light ...
