The role of the meningeal lymphatic in the brain clearing

Here in ex vivo (confocal imaging) and in vivo (optical coherent tomography) experiments on adult mice, we clearly demonstrate that the meningeal lymphatic drainage is an important mechanism for the brain clearing that might be also pathway for the brain clearing from metabolites and waste products that requests further detailed studies. Photodynamic effects stimulate the meningeal/cervical drainage opening new ideas for development of novel methods of activation of brain clearing that might be progressive strategies in therapy of neurovegetative diseases.
