New study discovers genetic changes linked to leukaemia in children with Down’s syndrome

Researchers at the University of Oxford, in collaboration with colleagues from Hannover Medical School and Martin-Luther-University Halle-Wittenberg, have discovered the specific gene mutations that are required for the development of leukaemia in children with Down’s syndrome. Children with Down’s syndrome have a 150-fold increased risk of myeloid leukaemia, and while […]

New ALS biomarkers, potential new drug targets described by researchers

Amyotrophic lateral sclerosis, or ALS, is an adult-onset neurodegenerative disease that causes paralysis and ultimately death when the nerves enervating the lungs cease to carry the signals needed for breathing. The disease has what is called a “focal onset,” where paralysis starts with an arm or a leg and spreads […]

New vaccine strategy boosts T-cell therapy

A promising new way to treat some types of cancer is to program the patient’s own T cells to destroy the cancerous cells. This approach, termed CAR-T cell therapy, is now used to combat some types of leukemia, but so far it has not worked well against solid tumors such […]

Southampton scientists make breakthrough in search for future drugs for age-related blindness

University of Southampton researchers have developed an innovative solution to treating sight loss in old age. Led by Professors Andrew Lotery, Jessica Teeling and Dr Arjuna Ratnayaka, the study has been able to replicate important features of dry age-related macular degeneration (AMD) in mice. These mice quickly develop damage in their retinas similar to […]

High Intensity Interval Training (HIIT) may prevent cognitive decline

High intensity interval training (HIIT) may be doing more than just keeping you fit and strong – it may also help prevent age-related cognitive illnesses, such as dementia. A University of Queensland study found high intensity interval exercise may be more effective than continuous exercise in increasing brain blood flow […]

Infection-fighting protein senses protein misfolding in non-infected cells

Researchers at the University of Toronto have uncovered an immune mechanism where host cells combat bacterial infection – and that a protein crucial to the process can sense and respond to misfolded proteins in all mammalian cells. The protein is called heme-regulated inhibitor, or HRI, and the researchers showed that […]

Cardiac Genetic Mutation May Not Always Predict Heart Disease

Researchers at Penn Medicine and Geisinger find only 5 percent of patients with a mutation of the TTN gene have dilated cardiomyopathy, despite changes in heart function. More than 750,000 people in the United States have dilated cardiomyopathy, a potentially life-threatening condition in which the heart’s main pumping chamber, the […]
