Medical Xpress / Specialized macrophages on adipose nerves curb age-related inflammation in mice
Yale School of Medicine-led research reports that nerve-associated macrophages help maintain healthy fat over a lifespan and curb age-related inflammation.
Medical Xpress / Immune defense punches holes in the heart, research reveals
In a study published in Science, researchers found that the defense protein "Resistin like molecule gamma" (Relmy), produced by neutrophils, punches holes into heart cells after a heart attack. This promotes dangerous, fast, ...
Medical Xpress / How fat disables the brain's immune shield in Alzheimer's disease
It was long thought that fat in the brain played no role in neurodegenerative diseases, but Purdue University researchers are challenging that assumption.
Medical Xpress / Rethinking how our brains build the neural networks underlying motor memories
For every motor skill you've ever learned, whether it's walking or watchmaking, there is a small ensemble of neurons in your brain that makes that movement happen. Our brains trigger these ensembles—what we sometimes call ...
Medical Xpress / Research reveals a promising new target to thwart Alzheimer's decades before symptoms start
A person will have Alzheimer's years before ever knowing it. The disorienting erasure of memories, language, thoughts—in essence, all that makes up one's unique sense of self—is the final act of this enigmatic disease ...
Medical Xpress / Discovery reveals how chromosome ends can be protected
Researchers have uncovered a previously unknown mechanism that safeguards the chromosome ends from being mistakenly repaired by the cell. While DNA repair is vital for survival, attempts to repair the chromosome ends—called ...
Medical Xpress / Breast cell changes in motherhood provides clues to breastfeeding difficulties
In a study in mice, researchers have identified genes associated with the dramatic transformation of the mammary gland in pregnancy, breastfeeding, and after breastfeeding as it returns to its resting state.
Medical Xpress / High consumption of ultra-processed foods linked to systemic inflammation
Ultra-processed foods (UPFs) are industrially altered products—like soda, snacks and processed meats—packed with additives and stripped of nutrients. Hundreds of new ingredients, previously unknown to the human body, ...
Medical Xpress / Research shows how Mediterranean-style diet in pregnancy can lead to improved mother and infant health
A Mediterranean-style diet, rich in fiber, vegetable proteins and healthy fats, benefits maternal health during pregnancy and breastfeeding. In addition to improving intestinal function and mucosal immunity, it also prevents ...
Medical Xpress / Warming climate drives dengue surge across Asia and the Americas, study shows
Warmer weather across the globe is reshaping the landscape of human health. A case in point is dengue fever, a mosquito-borne disease once confined largely to the tropics, which often brings flu-like symptoms, and without ...
Medical Xpress / Why a promising ALS drug failed—despite hitting its target
A new Emory University study, led by the Emory ALS Center and the Center for Neurodegenerative Disease at Emory's Goizueta Brain Health Institute, sheds light on why a once-promising experimental medication for amyotrophic ...
Medical Xpress / AI tool pinpoints genes and drug combos to restore health in diseased cells
In a move that could reshape drug discovery, researchers at Harvard Medical School have designed an artificial intelligence model capable of identifying treatments that reverse disease states in cells.
