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 ...

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, ...

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 ...

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 ...

CD4+ T cells, or helper T cells, are one type of lymphocyte that helps coordinate the immune response against infection and disease. They interact and activate other cells in the immune system. The ...

The immune cell repertoire is composed of many different cell types that are orchestrated in response to infection and other pathogens that enter the body. As a result, the body can defend itself ...

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 ...

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 ...
