Mouse meningeal lymphatics (IMAGE) Washington University School of Medicine Caption The drainage network in a mouse's brain is outlined in blue and green, and dotted with clumps of the Alzheimer's protein amyloid beta (red). Researchers at Washington University School of Medicine in St. Louis have found that improving the function of the network, known as the meningeal lymphatics, can make certain experimental Alzheimer's therapies more effective in mice.
