Immune cell interlopers breach—and repair—brain barrier in mice
The choroid plexus, the protective network of blood vessels and epithelial cells that line the brain’s ventricles, recruits neutrophils and macrophages during inflammation, a new study shows.

Immune-activation model mice escape infantile amnesia, retain early memories
Male pups born to mothers treated with immune-stimulating molecules show autism-like behaviors and, unlike wildtype animals, do not lose memories formed during early life.
