Blood-brain barrier

Settled at Birth: Blood Vessels Remember Their Origins

Blood vessels originating from lymphatic vessels were found to be tailored to specific functions


The cells that keep blood vessels in the pituitary permeable to hormones may hold the key to future drug delivery

Immunofluorescence microscope image of the choroid plexus. Epithelial cells are in green and chemokine proteins (CXCL10) are in red

Weizmann Institute researchers suggest that the brain's “immunological age” is what counts...

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

Shifts in our immune system as we age might explain how older brains get “rusty”
