Proteins long known to be essential for hearing have been hiding a talent: they also act as gatekeepers that shuffle fatty ...

The regulatory division of the immune system is vital for its overall function. Immune T cells originate in the bone marrow and then travel to the thymus—a kind of biological police academy. 2 Here, ...

Until now, doctors knew hepatic stellate cells mainly as drivers of liver fibrosis. The actual functions of this cell type have hardly been studied to date. Researchers have now determined that ...

A new study by physicists and neuroscientists from the University of Chicago, Harvard and Yale describes how connectivity among neurons comes about through general principles of networking and ...

Investigators at Hospital for Special Surgery (HSS) have discovered that at the time of total knee replacement, women have significantly increased levels of immune cells called mast cells in synovial ...

Cancer is a disease that causes abnormal cells to reproduce and spread to other parts of the body, which can result in tumors or damage to the immune system that may become fatal. Healthy cells follow ...

Parkinson's disease is associated with toxic clumps of the alpha-synuclein protein in the brain, which disrupt healthy cell communication. Now, a new study shows another way this protein may damage ...

Scientists have long known that people living at high altitudes, where oxygen levels are low, have lower rates of diabetes than people living closer to sea level. But the mechanism of this protection ...

Northwestern Medicine scientists have identified the cellular mechanisms that cause immune cells to differentiate and ultimately lose function during viral infection, findings that could improve ...

Men tend to lose the Y chromosome from their cells as they age. But because the Y bears few genes other than for male determination, it was thought this loss would not affect health. But evidence has ...
