(Press-News.org) GRAND RAPIDS, Mich. (Aug. 5, 2025) — For cancer- and infection-fighting T cells, glucose offers far more than a simple sugar rush.
A new discovery by Van Andel Institute scientists reveals that glucose, an essential cellular fuel that powers immune cells, also aids in T cells’ internal communication and boosts their cancer-fighting properties. The findings may help optimize T cells’ ability to combat cancer and other diseases.
A study describing the work published today in Cell Metabolism.
“Immune cells are highly influenced by their environment” said Joseph Longo, Ph.D., the study’s first author and a postdoctoral fellow in the lab of Russell Jones, Ph.D. “We knew that T cells need access to glucose to function, but we didn’t know exactly why. It was previously thought that T cells mainly break down glucose for energy, but our new work shows that T cells use glucose as a building block for other molecules that are necessary to support T cells’ anti-cancer properties.”
The findings reveal that T cells allocate significant portions of glucose to build large molecules called glycosphingolipids (GSLs). These sugar-fat compounds are essential for T cell growth and making proteins that T cells use to combat cancer.
GSLs help form fat-rich structures on T cell surfaces called lipid rafts, which bring together cell signaling proteins that instruct the T cell to kill cancer cells. Without GSLs, these signals are weaker, making T cells less effective at destroying tumors.
“Both T cells and cancer cells leverage different nutrients to support varying aspects of their function,” Jones said. “The more we know about these different fuel sources, the better we can support T cells’ innate cancer-fighting abilities while also developing ways to possibly make cancer cells more vulnerable to immune attack.”

The experts, business leaders, and policymakers shaping the future of America’s energy industry will convene at the 11th annual Energy Symposium presented by the Kay Bailey Hutchison Energy Center at The University of Texas at Austin on Friday, Sept. 12. Registration is open to the public.
Themed “The Energy Imperative,” this year’s symposium invites guests to meaningful conversations around the opportunities and challenges in the rapidly evolving energy space. Speakers and panelists will consider how the latest advances in energy innovation, security, and investment are being put to the test.
“UT Austin is one of the nation’s ...
Perovskite semiconductors are an exciting new material for use in solar cells. They are extremely thin and flexible, easy and inexpensive to manufacture, and highly efficient. However, two hurdles must be overcome before perovskite solar cells can be marketed on a large scale: firstly, they are not yet stable over decades, and secondly, the most powerful perovskite materials contain lead. An interesting, non-toxic alternative being investigated at HZB is tin perovskite solar cells, which are potentially more stable than their lead-containing counterparts. Thanks to their special electro-optical properties, they are particularly well suited to tandem ...
It might be humbling to consider, but cockroaches and people have more in common than we knew.
Biologists at the University of Cincinnati discovered that some cockroaches, like people, need more sleep when they’re pregnant. And baby cockroaches need the mom to sleep longer for proper development.
The study was published in the Journal of Experimental Biology.
“A lot of us take adequate sleep for granted because we don’t usually experience an immediate adverse effect of sleep deprivation,” said study co-author Oluwaseun Ajayi, a postdoctoral researcher in UC’s College of Arts and Sciences.
“The truth is the health consequences ...
As companies increasingly compete on the basis of technology, brand, and knowledge, a new study reveals that the effectiveness of corporate boards plays a critical role in maximizing the value of intangible assets—especially during international expansion through acquisitions.
In a study recently published in the Global Strategy Journal, researchers Xavier Martin (Tilburg University) and Tao Han (emlyon business school) analyzed 675 cross-border acquisitions by U.S. public firms to understand how intangible assets contribute to firm value abroad—and under what conditions.
Their findings are clear: while firms with high R&D and advertising intensity ...
Stress internalization is a significant risk factor for age-related cognitive decline in older Chinese Americans, according to Rutgers Health researchers.
The study, published in The Journal of Prevention of Alzheimer’s Disease by researchers from the Rutgers Institute for Health, Health Care Policy and Aging Research, examined multiple risk and resilience factors associated with cognitive decline in Chinese adults older than 60.
Researchers chose to study this population because older Chinese Americans are historically underrepresented ...
Primates - the group of animals that includes monkeys, apes and humans - first evolved in cold, seasonal climates around 66 million years ago, not in the warm tropical forests scientists previously believed.
Researchers from the University of Reading used statistical modelling and fossil data to reconstruct ancient environments and trace where the common ancestors of all modern primates lived.
The study, published today (Tuesday, 5 August) in the journal PNAS, says these first primates most likely lived in North America in a cold climate with hot summers and freezing winters, overturning the long-held "warm tropical ...
It’s known as biology’s central dogma: All living organisms’ genetic information is stored in DNA, which is transcribed into RNA, which is translated into proteins that perform nearly all essential tasks in a cell. A tiny cellular machine called the ribosome builds a protein until it’s signaled to stop, and the protein is released into the cell through a reaction with a water molecule.
But scientists have long puzzled over one detail: If all it takes is a water molecule to release the finished protein, why doesn’t it happen by accident?
Now researchers ...
For a wide variety of earthquake scenarios in Alaska, an earthquake early warning (EEW) system could provide at least 10 seconds of warning time for hazardous shaking, according to a new report.
Increasing the density and improving the spacing of seismic stations around the state could add 5 to 15 seconds to these estimated warning times, write Alexander Fozkos and Michael West at the University of Alaska Fairbanks. Alaska experiences tens of thousands of earthquakes each year, and has been the site some of the world’s largest and most destructive seismic events.
The study’s findings published in the Bulletin of the Seismological Society of America could help ...
Young chimpanzees learn their communication style from their mother and maternal relatives, but show little similarity to the communication behavior of their father and paternal relatives, according to a study publishing August 5th in the open-access journal PLOS Biology by Joseph Mine at the University of Zurich, Switzerland, and colleagues.
Human children learn how to communicate as they develop, and their communication behavior is heavily influenced by their main caregivers. Although chimpanzees also communicate ...
A new study finds that kids with obesity are more likely to have obese parents because they inherit obesity-related genes, and to a smaller extent, are impacted indirectly by genes carried by the mother – even when those genes aren’t passed down. A new study led by Liam Wright of the University College London, UK, and colleagues, reports these findings August 5th in the open-access journal PLOS Genetics.
Studies commonly show that children with obesity often have parents with obesity, but the cause of this trend has been poorly understood. ...
