Medical Xpress / Senescent astrocytes discovered in Alzheimer's brains point to new treatment targets
Researchers from the NeuroAD group (Neuropathology of Alzheimer's Disease) within the Department of Cell Biology, Genetics and Physiology at the University of Málaga, also affiliated with IBIMA–BIONAND Platform and CIBERNED, ...
Medical Xpress / Studies show 11 genetic variants affect gut microbiome
In two new studies on 28,000 individuals, researchers are able to show that genetic variants in 11 regions of the human genome have a clear influence on which bacteria are in the gut and what they do there. Only two genetic ...
Medical Xpress / Sensing local fibers in pancreatic tumors, cancer cells 'choose' to either grow or tolerate treatment
A feature of pancreatic cancer cells' surroundings determines whether they grow fast or become resistant to chemotherapy, a new study shows. The ability of these cancer cells to adapt quickly and toggle between biological ...
Medical Xpress / Dual brakes on T-cells: New targets found to boost immunity in chronic infections
Northwestern Medicine scientists have identified the cellular mechanisms that cause immune cells to differentiate and ultimately lose function during viral infection, findings that could improve treatments to control chronic ...
Medical Xpress / Alzheimer's gene boosts seizures, but pathway can be targeted, study finds
The gene most strongly correlated with Alzheimer's disease also boosts seizure activity by decreasing levels of ion pumps and energy-producing enzymes in neurons, a new study by researchers at the University of Illinois Urbana-Champaign ...
Medical Xpress / Cancer virus imaging helps uncover potential therapeutic targets
New research from the University of Minnesota School of Dentistry and Masonic Cancer Center is providing important new insights into the structure of a human virus that causes blood cancer. In their study published in Nature ...
Medical Xpress / Study suggests toddlers' ultraprocessed diets at age two linked to lower IQ
A new analysis from the 2015 Pelotas Birth Cohort suggests that dietary patterns at just 2 years of age are associated with cognitive performance at ages 6 and 7. The findings add to growing global evidence that early childhood ...
Medical Xpress / How bacteria may promote breast cancer
Researchers at the Johns Hopkins Kimmel Cancer Center have discovered how certain pathogenic bacteria in gut and breast tissue can promote breast cancer development and progression by hijacking a key metabolic enzyme known ...
Medical Xpress / Optimizing CAR T-cell therapy to tackle solid tumors
In 2024, Professor Sebastian Kobold's research group at LMU University Hospital had already shown that the metabolite prostaglandin E2 can block T cells—the killer cells of the immune system—in the vicinity of a tumor, ...
Medical Xpress / Ketamine's 'mystical' effects fail to explain alcohol abstinence gains, study suggests
The psychedelic effects recreational users often seek from taking ketamine do not predict the therapeutic benefits for people being treated for alcohol use disorder. The popular theory, which says that ketamine may have its ...
Medical Xpress / NSMF protein identified as key regulator in colorectal cancer
A research team affiliated with UNIST has unveiled a novel approach to halt the progression of colorectal cancer by inducing irreversible cellular aging. Their findings demonstrate that suppressing a neural protein called ...
Medical Xpress / Feeling unsafe in neighborhoods may predict lower cognition and more mental health symptoms
Children and adolescents already have a lot on their minds, from schoolwork to friendships to family dynamics. If they also worry about the safety in their own neighborhoods, those mental tasks might become even more difficult. ...
