Medical Xpress / Identifying immune pathways driving aggressive brain cancers
A new study has uncovered a key mechanism that helps one of the deadliest brain cancers evade the immune system, according to the study published in The Journal of Clinical Investigation.
Medical Xpress / Vulnerable ALS neurons reveal molecular warning signs before cell death begins
A new study from the Knight Initiative for Brain Resilience researchers may help explain an enduring mystery about amyotrophic lateral sclerosis (ALS): why the disease kills off some of the brain and spinal cord's movement-controlling ...
Medical Xpress / Alcohol absorption nearly doubles after bariatric surgery, raising long-term misuse risk
Your body absorbs alcohol much more rapidly after bariatric surgery. Patients need to know this when they choose the kind of surgery they will have. "Bariatric surgery can come with a price. Patients have a significantly ...
Medical Xpress / Small-molecule antiviral drug targets ACE2 receptor to block coronaviruses from entering cells
The ongoing evolution of SARS-CoV-2, particularly the rapid emergence of the omicron variant and its sublineages, has weakened the effectiveness of existing vaccines and antiviral drugs, underscoring the potential risk of ...
Medical Xpress / Nanotech platform combining paclitaxel with siRNA boosts immune response against lung cancer
Researchers at the University of Arizona R. Ken Coit College of Pharmacy have developed a new strategy that helps the immune system recognize and attack lung cancer tumors more effectively. By packaging a chemotherapy drug ...
Medical Xpress / Unfolding stomach capsule could target ulcer-causing bacteria for 48 hours
Between 50% and 100% of people in countries with poor access to clean water are infected with a bacterium called Helicobacter pylori. This bacterium is a leading cause of stomach ulcers, and it can even cause gastric cancer.
Medical Xpress / CAR T cell therapy leads to 10-year remissions in B-cell lymphoma patients
After a median follow-up of 10 years, more than one-third of patients with large B-cell lymphoma and nearly half of patients with follicular lymphoma who received a single infusion of tisagenlecleucel—the CAR T-cell therapy ...
Medical Xpress / Special protein in the brain's cleansing system may contribute to loss of brain function in Alzheimer's
Alzheimer's disease is a progressive and permanent loss of nerve cells in the brain. The breakdown causes memory loss, functional impairment and personality changes. In a new study published in Nature Aging, researchers found ...
Medical Xpress / Geometric neural 'map' may help bilingual brains navigate between languages
Anyone who speaks more than one language knows the feeling of expressing the same thought through entirely different linguistic lenses. A new study by researchers at Rice University and Baylor College of Medicine reveals ...
Medical Xpress / AI-aided 'master key' vaccine may block entire virus families, not single strains
Known by acronyms that need no explanation, viruses like COVID, SARS and Ebola conjure images of medics in protective suits and spark fear in populations worldwide.
Medical Xpress / How 'peacemakers' of the immune system could unlock long-term disease remission
"Peacemaker" immune cells could help treat diseases ranging from type 1 diabetes to neurodegeneration by restoring immune tolerance, according to a new paper in Frontiers in Science.
Medical Xpress / New Tfr cell model uncovers molecular switches that restrain antibody responses
For the immune system to effectively combat pathogens, antibody responses must be precisely controlled. So-called follicular regulatory T cells (Tfr cells) play a key role in this process by limiting excessive immune responses ...
