Medical Xpress / Immune cell subset reveals biological age beyond chronological years
Ben-Gurion University of the Negev's Prof. Alon Monsonego had discovered that T helper lymphocytes, a subset of immune cells which regulate immunity, undergo functional changes with age. These changes can indicate the biological ...
Medical Xpress / Mutation yields hot new clues for treating immune 'cold' tumors
Immune checkpoint inhibitors (ICIs) emerged in the US about 15 years ago as an exciting class of cancer treatments that have achieved complete and durable remissions for thousands of people with end-stage metastatic cancers. ...
Medical Xpress / Attention lapses due to sleep deprivation coincide with a flushing of fluid from the brain, research reveals
Nearly everyone has experienced it: After a night of poor sleep, you don't feel as alert as you should. Your brain might seem foggy, and your mind drifts off when you should be paying attention.
Medical Xpress / Chemists design candidate drug against diabetes
Researchers from the University at Albany and NYU Grossman School of Medicine have found a way to block a key cellular pathway known to drive chronic inflammation and impaired wound healing in people with diabetes.
Medical Xpress / Capturing cancer cells from blood could help doctors choose the right breast cancer treatment
Doctors may be able to spare patients unnecessarily aggressive breast cancer treatments by collecting and testing cancer cells in patients' blood, research from the University of Michigan and the University of Kansas suggests.
Medical Xpress / Detailed brain growth atlas in mice offers insights into brain development
Brain growth and maturation doesn't progress in a linear, stepwise fashion. Instead, it's a dynamic, choreographed sequence that shifts in response to genetics and external stimuli like sight and sound. This is the first ...
Medical Xpress / Chemotherapy nerve damage linked to immune cell stress pathway activation
Scientists at Wake Forest University School of Medicine, in collaboration with researchers at Weill Cornell Medicine, have made a breakthrough in understanding why many cancer patients develop nerve damage after chemotherapy. ...
Medical Xpress / Scientists uncover how support cells, once thought harmless, send damaging signals that weaken the heart
Heart failure (HF) is one of the leading causes of death and disability worldwide, affecting millions of people and placing an enormous burden on health care systems. The disease occurs when the heart can no longer pump blood ...
Medical Xpress / Changing the 'packaging' of DNA in neurons can turn memories on or off in mice
Our experiences leave traces in the brain, stored in small groups of cells called engrams. Engrams are thought to hold the information of a memory and are reactivated when we remember, which makes them very interesting for ...
Medical Xpress / Sensory expectations configure neural responses before disturbances occur, study reveals
A study led by Jonathan Michaels, a Faculty of Health professor at York's School of Kinesiology and Health Science, reveals how the brains of humans and monkeys use sensory expectations to prepare for unexpected disturbances, ...
Medical Xpress / How age affects vaccine responses and how to make them better
As flu season approaches and public health officials roll out their annual push for vaccination, Allen Institute scientists are learning why vaccines can trigger a weaker response in older adults, around age 65, and what ...
Medical Xpress / The minimal circuit of the circadian clock: Just four neurons keep fruit flies on schedule, study finds
A tiny neural network is sufficient to control the daily rhythm of the fruit fly, Drosophila melanogaster. Researchers at the University of Würzburg have shown that only four specialized nerve cells are necessary to drive ...
