Astrocyte Contribution to Sensory Hypersensitivity in Fragile X Syndrome

Most Fragile X research has focused on one type of brain cells: neurons. But mounting evidence point to problems with astrocytes, star-shaped cells which are vitally important to normal brain function. This team is working to understand how astrocytes are involved in Fragile X and develop treatment approaches that targets astrocytes alone.

Many people with Fragile X syndrome are hyper-sensitive to sights and sounds, and Electroencephalography (EEG) studies show that there are abnormalities in brain circuits. EEG studies show similar changes in Fragile X mice. So the team will use EEG tests in mice to find which drugs best reduce hypersensitivity. They can then easily move on to human EEG-based clinical trials. What they learn will tell us much more about why people with Fragile X are hypersensitive – and which drugs could best help them.

All cells have a kind of housecleaning service which sweeps away genetic errors. This is called nonsense-mediated mRNA decay (NMD). With a previous FRAXA grant, this team discovered runaway NMD in cells of Fragile X patients. It’s not yet known how this impacts people with Fragile X. With this grant, Dr. Maquat and Dr. Kurosaki will test drugs which can bring NMD back to normal levels.
