Immune system

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
