Glymphatic Drainage System

Lymphatic drain of the brain and the potential for degenerative disease therapies.

Drainage of the brain fluids managed by the brain's glial cells is termed the glymphatic system.

The lymphatic drainage system in the brain has been undetected until now because it is so hard to see. It was finally revealed by new imaging techniques. In this image of mouse meninges lymphatic vessels (red) are shown along side the blood vasculature (green).
