Bacteria naturally adapt to various environmental stimuli and as they mutate, these changes can make them resistant to drugs that would kill or slow their growth. In a recent article published in PLoS Genetics, UCF College of Medicine microbiologist Dr. Salvador Almagro-Moreno uncovers the evolutionary origins of antimicrobial resistance (AMR) in bacteria. His studies on […]
Led by researchers from NYU Grossman School of Medicine and University of Szeged in Hungary, a new study in mice and rats found that restoring certain signals in a brain region that processes smells countered depression. Publishing in the journal Neuron online May 9, the study results revolve around nerve cells (neurons), which “fire” — […]
New research from Boston Medical Center, published in iScience, suggests that concomitant tuberculosis disease has a significant impact on HIV immune responses and the viruses circulating in people living with HIV. Tuberculosis infects more than 2 billion people in the world, and although tuberculosis is the most common co-infection in people living with HIV, previous […]
Even mild concussion can cause long-lasting effects to the brain, according to researchers at the University of Cambridge. Using data from a Europe-wide study, the team has shown that for almost a half of all people who receive a knock to the head, there are changes in how regions of the brain communicate with each […]
Scientists at University of California San Diego have discovered a property of T cells that could inspire new anti-tumor therapeutics. Through a previously undescribed form of cell auto-signaling, T cells were shown to activate themselves in peripheral tissues, fueling their ability to attack tumors. The study was published May 8, 2023 in Immunity. T cells […]
Salk scientists have uncovered an unexpected molecular target of a common treatment for alopecia, a condition in which a person’s immune system attacks their own hair follicles, causing hair loss. The findings, published in Nature Immunology on June 23, 2022, describe how immune cells called regulatory T cells interact with skin cells using a hormone […]
Reports of near-death experiences — with tales of white light, visits from departed loved ones, hearing voices, among other attributes — capture our imagination and are deeply engrained in our cultural landscape. The fact that these reports share so many common elements begs the question of whether there is something fundamentally real underpinning them — […]
After a stroke, physical activity can be pivotal to successful recovery. People who spend four hours a week exercising after their stroke achieve better functional recovery within six months than those who do not, a University of Gothenburg study shows. The study, now published in the scientific journal JAMA Network Open, is based on data […]
Researchers at the UCLA David Geffen School of Medicine, the Howard Hughes Medical Institute at UCLA and the National Institutes of Health have developed a zebrafish model that provides new insight into how the brain acquires essential omega-3 fatty acids, including docosahexaenoic acid (DHA) and linolenic acid (ALA). Their findings, published in Nature Communications, have […]
A new Nature Immunologystudy led by University of Pittsburgh and National Institutes of Health researchers sheds light on how a rare type of helper T cell, called Th9, can drive allergic disease, suggesting new precision medicine approaches to treating allergies in patients with high levels of Th9. “Th9 cells are kind of like the black […]
