A new study finds that microglia with mutant TREM2 protein reduce brain circuit connections, promote inflammation and contribute to Alzheimer's pathology in other ways. A rare but potent genetic ...

New study shows that microglia cells 'listen in' to neighboring neurons and change to match them. From everyday actions like walking and talking to feats of athletic or academic excellence, the brain ...

During development, there are known sex-related differences in how microglia function. But into adulthood, there was thought to be less variation in how they behave. Microglia maintain neuronal ...

Microglia, the immune cells that protect the brain, are thought to maintain a healthy brain environment by removing unwanted ...

Many neurodegenerative diseases, or conditions that result from the loss of function or death of brain cells, remain largely untreatable. Most available treatments target just one of the multiple ...

Researchers now want to understand if other environmental exposures impact microglia similarly, and whether these changes lead to long-term alterations in brain circuitry and function. Lowery, R.L., ...

Immune system changes in the pregnant body that protect the fetus appear to extend to the brain, where a decrease in immune cells late in gestation may factor into the onset of maternal behavior, new ...

A collision happens. Someone is hurt, a head injury, a concussion. Just as the first responders arrive to help the person, inside the brain, another "crew" of responders is busy clearing debris and ...

Many people experience temporary cognitive impairment immediately after surgery. In people over age 60, however, about 1 in ...
