Study reveals key role of sugars in immune cell movement during psoriasis

New research has updated our understanding of how sugars, known as glycans, help immune cells move into skin in the inflammatory disease, psoriasis.

Loud noise exposure worsens motor deficits in Parkinson’s disease model

In the development of Parkinson's disease, it may not be a good idea to turn the amp to 11. High-volume noise exposure produced motor deficits in a mouse model of early-stage Parkinson's disease, and established a link between the auditory processing and movement areas of the brain, according to a study published November 4th in the open-access journal PLOS Biology by Pei Zhang from the Huazhong University of Science and Technology in Wuhan, China, and colleagues.

Living near cannabis stores linked to more frequent use and less heavy drinking

A statewide study of more than 60,000 adult Oregonians shows that living near cannabis retail stores is associated with a greater tendency toward frequent cannabis use but a lower likelihood of heavy alcohol consumption.

Breakthrough research offers first targeted treatment option for NRAS-mutant melanoma

New research from Moffitt Cancer Center shows that RAS(ON) multi-selective inhibition can directly block tumor growth and activate the immune system, offering the first targeted approach for patients with NRAS-mutant melanoma, an aggressive form of skin cancer with limited treatment options beyond immune checkpoint inhibitors.

UCLA experts call for individualized heart monitoring in breast cancer survivors

As breast cancer survival rates continue to climb - 4.3 million women in the U.S. are currently living with a history of the disease and in the next 10 years that number is expected to rise by another million - heart health has become an increasingly important part of survivorship care.

Study finds high intake of ultra-processed foods tied to reduced DNA methylation

Women who consumed more ultra-processed foods (UPFs) showed distinct DNA methylation patterns, mostly reduced across key gene regions. These exploratory findings suggest that high UPF intake may influence gene regulation through epigenetic mechanisms.

USC researchers map genetic architecture of the human corpus callosum

For the first time, a research team led by the Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI) at the Keck School of Medicine of USC has mapped the genetic architecture of a crucial part of the human brain known as the corpus callosum-the thick band of nerve fibers that connects the brain's left and right hemispheres.

UQ researchers capture first high-resolution images of the yellow fever virus

University of Queensland researchers have captured the first high-resolution images of the yellow fever virus (YFV), a potentially deadly viral disease transmitted by mosquitoes that affects the liver.

Survival patterns differ across types of early-onset dementia

The survival rates of people with early onset dementia-diagnosed before the age of 65-vary considerably by clinical type, but sex, age, family history and co-existing conditions aren't specific risk factors, finds research published online in the Journal of Neurology Neurosurgery & Psychiatry.

Swapping meat for plant-based options cuts fat but lowers protein, study finds

Replacing meat with plant-based or mycoprotein alternatives in UK diets lowers saturated fat and boosts fiber but reduces protein intake, especially for teens and older adults. The overall saturated fat reduction is too small to meaningfully affect cholesterol levels, researchers report in npj Science of Food.

Do GLP-1 drugs cause cancer? New review says no, may even protect

A comprehensive review in The Journal of Clinical Investigation finds no overall link between GLP-1 receptor agonists and increased cancer risk, countering early safety concerns. Instead, evidence suggests possible protective effects for certain cancers, supported by metabolic and immune-modulating mechanisms.

GLP-1 drugs calm inflammation beyond diabetes and weight loss

This Journal of Clinical Investigation review describes how glucagon-like peptide-1 (GLP-1)–based medicines reduce systemic and tissue inflammation through both weight-dependent and weight-independent mechanisms. It details preclinical and clinical evidence linking GLP-1 receptor activation to cardiovascular, renal, hepatic, neural, and joint anti-inflammatory effects while outlining uncertainties and future research needs.
