A new study reports that immune memory may contribute to neurodegenerative diseases.

Immune-like cells in the central nervous system are now recognized as key participants in the creation and maintenance of persistent pain.

The acute pain that results from injury or disease is very different from chronic pain.

Researchers find that about a quarter of the immune cells are replaced every year.

Just by activating these immune cells in the brain, scientists could make mice eat more and burn fewer calories.

Once thought only to attack neurons, immune cells turn out to be vital for central nervous system function.

Researchers document the diverse roles of immune cells in neuronal health and disease.

The immune cells—known for clearing dead cells—also chew up live progenitors in neurogenic regions of mouse brains. 

Glial cells were once considered neurons’ supporting actors, but new methods and model organisms are revealing their true importance in brain function.
