Scientists identify new drug strategy against fragile X syndrome

Scientists identify new drug strategy against fragile X syndrome: "The researchers have found that a class of drugs called phosphoinositide-3 (PI3) kinase inhibitors can correct defects in the anatomy of neurons seen in a mouse model of fragile X syndrome. In experiments with cultured neurons from the hippocampus, a brain region involved in learning and memory, the drugs could restore normal appearance and levels of protein production at synapses, the junctions between cells where chemical communication occurs. The results, published online this week in the Journal of Neuroscience, suggest that PI3 kinase inhibitors could help improve learning and cognition in individuals with fragile X syndrome."
