Medical Xpress / 'Parent' blood cells act as a buffer against the effects of aging
As people age, so do their stem cells. Scientists have known for years that the stem cells that go on to become blood cells show significant signs of aging that sometimes lead to leukemia, excessive blood clotting and other ...
Medical Xpress / Dry mRNA vaccine patches reveal design rules for room-temperature storage
New research could help make future mRNA vaccines easier to store and distribute. The study, involving RMIT University, the Massachusetts Institute of Technology and Harvard Medical School, identified conditions that help ...
Medical Xpress / New, improved method to find and isolate the strongest cancer-fighting immune cells
A new platform developed by researchers at the University of Texas MD Anderson Cancer Center quickly finds and isolates rare, tumor-reactive immune cells that are especially good at recognizing and attacking cancer cells, ...
Medical Xpress / Gut bacteria boost immune system, help send vitamin A to T cells
Scientists at UT Southwestern Medical Center have discovered that gut bacteria help regulate the development of the body's immune system by directing the movement of vitamin A through a previously unrecognized cellular network. ...
Medical Xpress / Losing TDP-43 protein in microglia disrupts myelin, causing motor deficits in mice
Rosa Chiara Paolicelli's team at the Department of Biomedical Sciences of Unil uncovered a new role for the TDP-43 protein in controlling the function of microglia, the immune cells of the brain. Their study shows how the ...
Medical Xpress / Lower diversity and poorer function of gut bacteria linked to frailty in older women
Researchers at the University of Gothenburg have identified clear links between the composition of gut bacteria and frailty in older women. In cases of high frailty, with an increased risk of illness and death, gut bacterial ...
Medical Xpress / New platform combines precision gene targeting with brain-wide delivery
A new study describes a gene therapy strategy that uses the brain's own glymphatic transport system to distribute engineered viral vectors throughout the brain. The approach addresses two major challenges in neurological ...
Medical Xpress / Mechanism linking chronic inflammation to reduced brain regeneration identified
A King's College London study, published in Nature Communications, offers insight into how long-term inflammation may contribute to cognitive decline in disorders such as Alzheimer's disease, aging, depression and the lingering ...
Medical Xpress / Study finds NFL players 4 times more likely to die due to neurodegenerative disease
A new study from Mass General Brigham, Boston University and the Concussion & CTE Foundation found that National Football League (NFL) players had higher rates of neurodegenerative disease-caused mortality than the general ...
Medical Xpress / What your tears could reveal about your brain
A few tears may someday reveal important clues about a person's neurological health. Researchers reporting in ACS Omega developed a low-cost electrochemical sensor designed to detect dopamine, a neurotransmitter involved ...
Medical Xpress / Genetic insights into a fluid-related brain condition in newborns
Early detection and treatment of congenital cerebral ventriculomegaly (CCV)—when a fetus's fluid-filled brain ventricles swell due to a condition called hydrocephalus—can help clinicians prevent developmental or neurological ...
Medical Xpress / Race and ethnicity modify the association between US socioeconomic status and metabolic disease
Higher socioeconomic status is not associated with equal reductions in rates of type 2 diabetes and obesity across all racial and ethnic groups in the United States, according to a new study published July 8, 2026, in the ...
