Antoine Louveau

French-American neuroscientist. Assistant Professor at the Lerner Research Institute, Cleveland Clinic, since 2018. Did his PhD in immunology in France and his postdoctoral work with Jonathan Kipnis at the University of Virginia School of Medicine, where the 2015 Nature meningeal-lymphatics paper was conducted. Now runs his own laboratory on CNS lymphatic function in neurological disease.

Stake§

Louveau's stake is scientific and clinical-translational. The Cleveland Clinic position connects the research to a major neurology-and-neurosurgery clinical infrastructure and to substantial NIH funding. The post-2015 work has continued the meningeal-lymphatic programme with extensions into multiple sclerosis, Alzheimer's, and other neuroinflammatory conditions.

The 2015 Nature paper, with Louveau as first author and Kipnis as senior author, is the work he will be most remembered for. The serendipitous discovery — during a different research project, mounting whole-dura preparations rather than the conventional dissected sections — revealed functional lymphatic vessels lining the dural sinuses that had been written out of the twentieth-century textbook understanding of CNS anatomy. The independent simultaneous confirmation by Aspelund et al. in Journal of Experimental Medicine gave the finding the kind of robustness that single discoveries rarely have.

The Cleveland Clinic laboratory has continued the meningeal- lymphatic programme since 2018, with particular focus on the role of CNS-lymphatic dysfunction in multiple sclerosis (where immune-cell trafficking through the meningeal vessels is clinically significant) and on the connection between meningeal lymphatics and the glymphatic system that Nedergaard had characterised three years earlier. The two systems together — glymphatic intra- parenchymal clearance, meningeal lymphatic drainage out — make the brain's fluid biology look much more like peripheral tissue fluid biology.

Louveau is the first-author figure on one of the most consequential anatomical findings of post-2010 neuroscience. The Cleveland Clinic independent programme since 2018 represents the transition from senior-author-supported postdoc to independent senior researcher. The meningeal- lymphatic framework his work established is now standard in neuroimmunology.
