Lymphatic Meningeal Role in Processes of Brain Clearing: in vivo Visualization
In the experiments on rats, Evans Blue dye and gold nanorods were injected into the brain parenchyma, followed by visualization with optical coherent tomography and a fluorescent microscopy. The results showed that meningeal lymphatics play an important role in the brain clearing, using markers introduced into the tissues. It has been shown that the deep cervical lymph node is the first anatomical “station” for the outflow of fluid from the brain. The data obtained shed light on the lymphatic mechanisms underlying the drainage and clearing of brain functions.
