An accumulation of T cells and astrocytes in postmortem brain tissue hints at possible autoimmune origins for many cases of autism.

The brain’s immune cells gobble up synapses in the hippocampi of rodents fed high-fat or high-sugar diets.

Immune cells travel through these passageways to get to injured tissue quickly, researchers say.

When a mouse’s brain undergoes traumatic injury, immune cells clear the dead from the affected area, after which blood cells swoop in to repair blood vessels.

Covering neuroscience research means choosing from an embarrassment of riches.
