New research in mice pinpoints disease-modifying molecules produced by astrocytes in Rett, fragile X and Down syndromes La Jolla, Sept 19, 2022.- Neurons often get most of the credit for keeping our brains sharp and functioning—as well as most of the blame when it comes to brain diseases. But star-shapedContinuar Leyendo
By Jim Schnabel New York, August 31, 2022.- The SARS-CoV-2 virus can infect specialized pacemaker cells that maintain the heart’s rhythmic beat, setting off a self-destruction process within the cells, according to a preclinical study co-led by researchers at Weill Cornell Medicine, NewYork-Presbyterian and NYU Grossman School of Medicine. TheContinuar Leyendo
As mice navigate different rooms in virtual reality, the prefrontal neurons (top) communicate with those in the hippocampus (bottom) to conjure associated memories. New York, August 21, 2022.- An unforgettable time at a restaurant is not just about the food. The odors, the decor, the sound of the band playing,Continuar Leyendo
Researchers and entrepreneurs have developed an implant made of collagen protein from pig’s skin, which resembles the human cornea. In a pilot study, the implant restored vision to 20 people with diseased corneas, most of whom were blind prior to receiving the implant. The study jointly led by researchers atContinuar Leyendo
Alzheimer’s disease can begin almost imperceptibly, often masquerading in the early months or years as forgetfulness that is common in older age. What causes the disease remains largely a mystery. Medford, MA, August 11, 2022.- But researchers at Tufts University and the University of Oxford, using a three-dimensional human tissueContinuar Leyendo
A case series which is the result of an international collaboration across 16 countries is published today (21 July 2022) in The New England Journal of Medicine (NEJM). The study, led by researchers at Queen Mary University of London, identifies new clinical symptoms of monkeypox infection, which will aid futureContinuar Leyendo
Mycobacterium tuberculosis, the causative agent of tuberculosis, remains the leading cause of infectious disease worldwide, affecting approximately a quarter of the globe’s population. Treatment of infections is problematic due to the emergence of drug-resistant strains; however, University of Oklahoma professor Helen Zgurskaya, an expert in antibiotic resistance, is leading researchContinuar Leyendo
Colorectal tumors are swarming with white blood cells, but whether these cells help or hinder the cancer is hotly debated. While some studies have shown that white blood cells heroically restrict tumor growth and combat colorectal cancer, equally compelling evidence casts the white blood cells as malignant co-conspirators — bolsteringContinuar Leyendo
Cancer cells produce small amounts of their own form of collagen, creating a unique extracellular matrix that affects the tumor microbiome and protects against immune responses, according to a new study by researchers at The University of Texas MD Anderson Cancer Center. This abnormal collagen structure is fundamentally different fromContinuar Leyendo
A team of Florida State University College of Medicine researchers has found a link between a specific protein in the brain and increased vulnerability to neurodegeneration for individuals with temporal lobe epilepsy (TLE). Tallahassee, FL, July 20, 2022.- Their findings are published in the Journal of Neurophysiology. TLE is theContinuar Leyendo
