Immunostaining of brain section in which the epithelial choroid plexus expresses TGF-β (green), hanging in the brain ventricle, the keyhole-like structure delineated by the ependymal lining (red). In the box, monocytes (green) entering via the choroidal vasculature. The composition reflects the immune-educative nature of the choroid plexus as a gatekeeper of the route to the injured parenchyma

Magnetic resonance imaging (MRI) scans of the brain in three children with a missing copy of the Chaserr gene. The scans performed at age 8 months or 4 years (top row) reveal structural changes in the brain, including reduced volume of the brain stem (asterisks) and decreased myelin coating of nerves (arrows) in deep-seated brain areas. These changes are less apparent at 1 month of age (bottom row)
