By trimming synapses in the adult mouse hippocampus, microglia help facilitate forgetting.

Clues about the biological mechanisms that contribute to a person’s chance of contemplating or attempting suicide

The biochemical mechanisms in the brain underlying suicidal behavior are beginning to come to light, and researchers hope they could one day lead to better treatment and prevention strategies.

Clinical trials that target human endogenous retroviruses to treat multiple sclerosis, ALS, and other ailments are underway, but many questions remain about how these sequences may disrupt our biology.

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

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.
