Medical Xpress / How immune cells deliver their deadly cargo: An unexpected connection to lipid metabolism
When immune cells strike, precision is everything. New research reveals how natural killer and T cells orchestrate the release of toxic granules—microscopic packages that destroy virus-infected or cancerous cells.
Medical Xpress / Deep sleep supports memory via brain fluid and neural rhythms, research finds
Researchers led by Masako Tamaki at the RIKEN Center for Brain Science in Japan report a link between deep sleep and cerebrospinal fluid, the clear liquid that surrounds and supports the brain and spinal cord. Published in ...
Medical Xpress / Automated algorithm can detect cancer in blood samples in as little as 10 minutes
When cancer spreads, tiny amounts of cells can break away from tumors and circulate in the bloodstream. A liquid biopsy is a means to detect the presence of cancer by detecting these cancer cells floating in blood samples. ...
Medical Xpress / Supercharging immune cells to fight drug resistant bowel cancer
Scientists at University College London have engineered a rare type of immune cell to kill slow-growing bowel cancer cells that are resistant to current therapies, a breakthrough that could lead to new treatments in the future.
Medical Xpress / 'Skinny fat' linked to silent artery damage
A new study led by researchers at McMaster University reveals that hidden fat deep inside the abdomen and liver may quietly damage arteries, even in people who appear healthy.
Medical Xpress / New antivirals could help prevent cold sores by changing cell structures
A class of antivirals called Pin1 inhibitors could reduce or stop outbreaks of herpes simplex virus 1 (HSV-1), the common infection behind oral herpes, according to new research published in Antiviral Research.
Medical Xpress / Surprising gene mutation in brain's immune cells linked to increased Alzheimer's risk
In a study published in Neuron, a research team at the Department of Neurology at Massachusetts General Hospital, aimed to understand how immune cells of the brain, called microglia, contribute to Alzheimer's disease (AD) ...
Medical Xpress / 'Craters' on surface of melanoma cells mark tumor-killing hotspots, study reveals
New research published in Cell finds the existence of craters on the surface of melanoma cells that serve as immune hubs, becoming major sites for tumor killing. These craters could serve as good markers for immunotherapy ...
Medical Xpress / Missing molecule holds clues to Down syndrome
New research suggests a missing brain molecule may hold the key to understanding—and potentially treating—the faulty neural circuits seen in Down syndrome. Restoring the molecule, called pleiotrophin, could enhance brain ...
Medical Xpress / Large language models prioritize helpfulness over accuracy in medical contexts, finds study
Large language models (LLMs) can store and recall vast quantities of medical information, but their ability to process this information in rational ways remains variable. A new study led by investigators from Mass General ...
Medical Xpress / When healing turns harmful: Adrenal support cells tied to cancer origin
A new study from Karolinska Institutet, published in npj Precision Oncology, shows that support cells in the adrenal gland can regenerate hormone-producing tissue after birth. The same cells may also act as a starting point ...
Medical Xpress / How tobacco retail exposure impacts smoking behavior
Studies have found that the density of tobacco retailers in a neighborhood is associated with smoking, the leading cause of preventable disease and death. But what if smokers and policymakers were able to understand the impact ...
