Medical Xpress / Reviving exhausted immune cells boosts tumor elimination
A new study has discovered a molecular signal that tumors exploit to exhaust the T cells meant to destroy them—and how silencing that signal could revive the body's immunity.
Medical Xpress / Evidence builds for disrupted mitochondria as cause of Parkinson's
For decades, scientists have known that mitochondria, which produce energy inside our cells, malfunction in Parkinson's disease. But a critical question remained: do the failing mitochondria cause Parkinson's, or do they ...
Medical Xpress / Medications change our gut microbiome in predictable ways, research reveals
Our gut microbiome is made up of trillions of bacteria and other microbes living in our intestines. These help our bodies break down food, assist our immune system, send chemical signals to our brain, and potentially serve ...
Medical Xpress / Next-generation microbiome medicine may transform Parkinson's treatment
The age-old advice to "trust your gut" could soon take on new meaning for people diagnosed with Parkinson's disease, thanks to a creative feat of bioengineering by researchers in the University of Georgia's College of Veterinary ...
Medical Xpress / Scientists identify two key targets of common cold virus
Scientists were pleased when they learned more about how the common cold gains a foothold in the body, identifying key cellular checkpoints that are important targets of the virus.
Medical Xpress / How the gut builds long-lasting immunity after viral infections
A new study led by University of Toronto researchers has shown that immune cells in the gut follow an atypical pathway to produce antibodies that provide long-term protection against viruses.
Medical Xpress / CRISPR breakthrough reverses chemotherapy resistance in lung cancer
In a major step forward for cancer care, researchers at ChristianaCare's Gene Editing Institute have shown that disabling the NRF2 gene with CRISPR technology can reverse chemotherapy resistance in lung cancer. The approach ...
Medical Xpress / Single-dose radiation before surgery can eradicate breast cancer
A single, targeted high dose of radiation delivered before other treatments could completely eradicate tumors in most women with early-stage, operable hormone-positive breast cancer, according to a study led by UT Southwestern ...
Medical Xpress / Precision therapy could stop breast cancer at the source
Researchers at the University of California San Diego School of Medicine have identified a promising new therapy for triple-negative breast cancer (TNBC), which is among the most aggressive and difficult-to-treat forms of ...
Medical Xpress / Tirzepatide may only temporarily suppress brain 'food noise' activity
A rare glimpse into the brain activity of a patient with obesity and loss of control eating on tirzepatide, marketed as Mounjaro and Zepbound, revealed that the medication suppresses signaling in the brain's "reward center" ...
Medical Xpress / Brain stimulation found to improve vision recovery after stroke
Scientists at EPFL have developed an innovative, non-invasive brain stimulation therapy to significantly improve visual function in stroke patients who have suffered vision loss following a stroke. The approach could offer ...
Medical Xpress / New study identifies part of brain animals use to make inferences
Animals survive in changing and unpredictable environments by not merely responding to new circumstances, but also, like humans, by forming inferences about their surroundings—for instance, squirrels understand that certain ...
