"Back in 2007, researchers at MIT’s Picower Institute for Learning and Memory in Cambridge, Massachusetts, discovered that mice with symptoms of Alzheimer’s disease regained long-term memories and the ability to learn when treated with a new type of experimental drug called a histone deacetylase (HDAC) inhibitor. Now that same team, led by Li-Huei Tsai, Picower Professor of Neuroscience, has pinpointed the gene involved. It’s called HDAC2." - Steven Perez from Bookmarklet
