BUFFALO, N.Y. — Drug discovery can be a frustrating process of trial and error. Scientists using fragment-based drug discovery link fragments of different molecules together to create a more potent drug but may not know whether a compound works until millions of dollars in research and development have already been spent. New University at Buffalo research may offer a more streamlined approach, allowing drug makers to determine the viability of a fragment-based design earlier in the process.  While developing a fragment-based drug to treat lung cancer, a team co-led by UB found that where they linked fragments together had a large effect on potency. “Despite ...

In a first-of-its-kind study published in the American Journal of Respiratory and Critical Care Medicine, physician-scientists from the University of Alabama at Birmingham Marnix E.

RIVERSIDE, Calif. -- For centuries, coronaviruses have triggered health crises and economic challenges, with SARS-CoV-2, the coronavirus that spreads COVID-19, being a recent example. One small protein in SARS-CoV-2, the Membrane protein, or M protein, is the most abundant and plays a crucial role in how the virus acquires its spherical structure. Nonetheless, this protein’s properties are not well understood. A research team led by a physicist at the University of California, Riverside, has devised a new method to make large quantities of M protein, and has characterized the protein’s ...

LA JOLLA, CA—Most cancers are thought to evade the immune system. These cancers don't carry very many mutations, and they aren’t infiltrated by cancer-fighting immune cells. Scientists call these cancers immunologically "cold." Now new research suggests such cancers aren't as "cold" as once thought. Researchers from the La Jolla Institute for Immunology (LJI), UC San Diego Moores Cancer Center, and UC San Diego, have found that patients with "cold" tumors actually do make cancer-fighting T cells.  This discovery opens the door to developing vaccines or therapies to increase T cell ...

Imagine: You find the dried-up remains of a once green and lush philodendron on your bookshelf and realize you can’t remember the last time you watered your houseplants. You soak the soil with water, hoping you can breathe life back into its desiccated husk, but it is futile. The plant has been too dehydrated for too long, and irreparable damage has been done. Now imagine that it isn’t your neglected houseplants that have been subjected to an unexpectedly dry growing season, but a field of wheat. With changes in global climate, such things are becoming more common and more of a concern for farmers, consumers, and researchers alike as the threat to food security intensifies. But ...

New research from the University of British Columbia reveals a safe path to overcoming food allergies for older children and others who can’t risk consuming allergens orally to build up their resistance. It’s called sublingual immunotherapy (SLIT), and it involves placing smaller amounts of food allergens under the tongue. A study conducted by UBC clinical professor and pediatric allergist Dr. Edmond Chan and his team at BC Children’s Hospital Research Institute found SLIT to be as safe and effective for high-risk older children and adolescents ...

Hamilton, ON, Feb. 28, 2024 – Diagnosing anemia in living people is typically a matter of a routine blood test. Retrospectively diagnosing anemia in people who died decades or even centuries ago is much more challenging since there is no blood left to test. Anthropologists at McMaster University and the University of Montreal, working with a hematologist colleague, have overcome that obstacle by developing a way to detect anemia through patterns in the structures of bones. Paleopathologists Megan Brickley, ...

Cancers begin with abnormal changes in individual cells, and the ability to track the accumulation of mutations at the single-cell level can shed new light on the early stages of the disease. Such knowledge could enable more effective early detection and treatment options for patients as well as more accurate predictions of disease progression. According to a paper in Nature Communications, a team of Rice University researchers led by Luay Nakhleh has developed a platform for integrating DNA and RNA data from single-cell sequencing with greater speed and precision than more recent, state-of-the-art technologies. The method, mapping cross domain ...

Neuroscientists at Fred Hutchinson Cancer Center have found that an often-overlooked type of brain cell called glia has more of a role in brain function than previously thought. In the journal Cell Reports, Fred Hutch neuroscientist Aakanksha Singhvi, PhD, and her team report that a single glial cell uses different molecules to communicate with different neurons. Careful clustering of these molecules ensures that the glial cell can conduct a distinct “conversation” with each neuron. Through these molecular facilitators, glia can influence how neurons respond to environmental cues like ...
