Research in mice shows that exercise mobilizes inflammation-countering T cells, lowering levels of interferon — a key driver of chronic inflammation, inflammatory diseases, and aging.

Seizures are like sudden electrical storms in the brain that can cause lasting damage. A set of immune cells in the brain called microglia may provide protection.

Blocking a specific gene in people in the early stages of cardiomyopathy could halt the development of scar tissue and delay heart failure.

Microglia, immune cells disguised as brain cells, are known as the janitors of the brain. Dialing up their usual duties just enough could provide an avenue to treat neurodegenerative disease.

Can underproduction of key immune cells contribute to Alzheimer's? A new study suggests the answer is yes.
