Medical Xpress / 'Off the shelf' immunotherapy could get a lift from gene-edited natural killer cells
Since scientists first discovered that human immune cells could be modified to become cancer-fighting agents, they've been trying to engineer a cell that's effective against solid tumors, which account for the vast majority ...
Medical Xpress / Differing immune responses in infants may explain increased severity of RSV over SARS-CoV-2
Young infants hospitalized with respiratory syncytial virus (RSV) often become much sicker than those infected with SARS-CoV-2, the virus that causes COVID-19. In a study published in Science Translational Medicine, scientists ...

Medical Xpress / Vitamin B7 reveals a new metabolic weak spot in some cancers
A research group at the University of Lausanne (Unil) has identified a new mechanism that exposes the vulnerability of tumor cells when they are deprived of vitamin B7. The ability of cells to adapt to fluctuations in nutrient ...
Medical Xpress / Scientists sharpen genetic maps to help pinpoint DNA changes that influence human health traits and disease risk
Scientists have identified how specific genetic changes function in cells to influence disease risk and other human health traits. By probing regions of DNA previously linked to disease, the work has created high-resolution ...
Medical Xpress / Why eczema often starts in childhood: New clues point to early immune 'overreaction'
A team of researchers at the Icahn School of Medicine at Mount Sinai, Weill Cornell Medicine, and other institutions have uncovered a key biological explanation for why eczema so often starts in childhood. The study, in young ...
Medical Xpress / AI, monkey brains, and the virtue of small thinking illuminate how the brain processes sight
What does it take to make AI that can pass as human? Try massive clusters of supercomputers. To build human-like intelligence, computer scientists think big. However, for neuroscientists who want to understand how real brains ...
Medical Xpress / Unlearning fear faster: Activating certain neurons can accelerate the process
Unlearning fear responses is a fundamental learning process in the brain. It allows us to flexibly react to formerly threatening situations once the danger is no longer present. This mechanism, known in research as "fear ...
Medical Xpress / Civilians face increasing harm from deadly explosive weapons, 17-country study finds

Medical Xpress / Surprising culprit leads to chronic rejection of transplanted lungs and hearts
Despite advances in the field of organ transplantation, long-term organ rejection that can become apparent a decade or more after a heart or lung transplant remains a common problem for patients. This chronic organ failure ...
Medical Xpress / How ketogenic diets help prevent seizures
A ketogenic diet—one that is high in fat and extremely low in carbohydrates—has been known for decades to reduce seizures in some epilepsy patients. But how the highly restrictive diet achieves these effects has not previously ...
