Exploring Drug Repurposing to Restore Hippocampal Function in FXS Mouse Models

A gene’s job is to produce a protein. In Fragile X syndrome, the FMR1 gene is mutated and cannot make FMRP, a protein which shapes connections between nerve cells (neurons) in the brain. These connections are the basis of learning and memory. This team has discovered a mechanism involving FMRP that is absolutely essential to control the connections between neurons. These connections are the basis of learning and memory. They will now test available drugs which directly target this mechanism, to see if they can treat Fragile X syndrome.

The Role of Astrocyte BMP Signaling in Fragile X Syndrome

Astrocytes are star-shaped cells that make up one fifth of all cells in the human brain. Recently researchers found a specific pathway in astrocytes that is overactive in Fragile X syndrome, and they hope to bring this pathway back to normal with a drug. With this grant, the team will try to correct the pathway in Fragile X mice. The hope is that they will find a new potential treatment approach for Fragile X syndrome.
