Read moreFunctional and Genomic Characterization of Interneurons in the Fmr1-KO Mouse Brain
The brain’s balance is maintained by two types of neurons: those that excite and those that inhibit activity. Like yin and yang, this balance is essential. This team has found fewer than normal inhibitory cells in the brains of Fragile X mice. They are now working to pinpoint this abnormality and find ways to restore the normal balance and function.
Read moreTargeting Serotonin 1A Receptors in Fmr1 Knockout Mice
Dr. Canal has discovered a promising treatment approach for Fragile X syndrome: new compounds which specifically and potently boost serotonin in the brain. The target is the brain’s serotonin 1A receptor.
Read moreCharacterization and Modulation of microRNAs in Fragile X Syndrome
Could microRNAs be a new path to treatment of Fragile X syndrome? MicroRNAs are disrupted in Fragile X, and so this team will work to understand what is going wrong and explore ways to correct it with drugs which directly target microRNAs.
Read moreCannabinoids as a Treatment for Fragile X Syndrome
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.

Experience the revival of arbaclofen as Allos Pharma Inc launches a new development program, providing renewed hope for the Fragile X community. Discover the impact of this experimental drug and the determination of those who never gave up.
Read moreAuditory System Dysfunction and Drug Tolerance in the Fragile X Mouse
FRAXA Research Foundation has awarded $90,000 over 2019-2021 to principal investigator Dr. Jay Gibson and postdoctoral fellow Dr. Andrew Holley at the University of Texas Southwestern Medical Center. They are investigating circuit mechanisms for auditory system dysfunction and drug tolerance in the Fragile X mouse model.
Read moreScientists Find a New Way to Reverse Symptoms of Fragile X
FRAXA Investigator and MIT Professor Mark Bear and his colleagues have identified a valuable new target for Fragile X therapeutics: GSK3 alpha. Several FRAXA research teams previously identified GSK3 beta as a treatment target for Fragile X. The catch is that, so far, GSK3 beta inhibitors have proven too toxic for regular use. Dr. Bear’s new discovery opens up the possibility of developing more selective compounds with less toxicity and fewer side effects. Interestingly, lithium inhibits both GSK3 versions – alpha and beta.
Read moreUnderstanding and Reversing Hypersensitivity to Sounds in Fragile X Syndrome
With a $90,000 grant from FRAXA Research Foundation over 2018-2019, Drs. Devin Binder, Iryna Ethell, and Patricia Pirbhoy at the University of California at Riverside aim to understand – and reverse – hypersensitivity to sound in Fragile X syndrome.
Read moreImpact of the Fragile X Community
At FRAXA Research Foundation, we are truly grateful for our Fragile X community and thousands of donors. We couldn’t keep moving the ball forward in research without your support. Each year FRAXA invests over $1 million in Fragile X research thanks to your support. Because we supported these three researchers, we were able to secure another $35 million in research aimed at identifying clinical trial outcome measures that will lead to human trials of promising treatments for those affected by Fragile X.
Read moreNewly Discovered Regulatory Pathways in Fragile X
Studies at Yale University and elsewhere are showing that FMRP plays a significant role in the regulation of potassium channels. Looking forward, potassium channel opener drugs could rescue some symptoms of Fragile X in humans.
Read moreIn Their Own Words: Reports From the International Fragile X Workshop
The 18th International Fragile X and Related Neurodevelopmental Disorders Workshop in Quebec, Canada, was a great success, featuring Fragile X much more heavily than any previous meeting in this series! We asked our speakers to summarize their work in their own words, with brief updates from researchers investigating Fragile X.
Read moreKimberly Huber, PhD, Explores Hyperexcitability in Fragile X Syndrome
Ever wonder why your child with Fragile X suddenly screams for no apparent reason or jumps and flaps uncontrollably seemingly for hours? You got it: hyperexcitability. But what exactly causes it? And what can fix it? Kimberly Huber, PhD, is working long and hard in her lab to answer those questions. Dr. Huber, professor, Neuroscience, UT Southwestern Medical Center, is seeking to understand how FMRP regulates connections between brain cells, called synapses, and the function of brain circuits, which are several connected brain cells.
Read moreFragile X Treatment: New Research Directions
In the wake of negative results from several high-profile clinical trials in Fragile X, we find ourselves questioning many of our previous assumptions about the nature of this disorder. After all, understanding the basic pathology of disease is critical to development of new treatments — this is true across the board, in all branches of medicine.

The National Institutes of Health has just announced new awards of $35 million over five years to support three Centers for Collaborative Research in Fragile X. Investigators at these centers will seek to better understand Fragile X-associated disorders and work toward developing effective treatments. All of these scientists have been funded for years by FRAXA Research Foundation, and now each team will receive over $2 million per year for five years!

With $135,000 in grants from FRAXA Research Foundation over several years, Dr. Khaleel Razak and Dr. Iryna Ethell explored robust biomarkers relevant to the FXS and the efficacy of minocycline treatment.
Read moreInherited Channelopathies in Cortical Circuits of Fmr1 KO Mice
With this two year award of $90,000, Dr. Zhang and Principal Investigator Dr. Andreas Frick at Neurocentre Magendie in France investigated channelopathies using Fragile X mice. Many other proteins are misregulated as a result of the absence of FMRP. It is known that many ion channels, the pores in the cell membrane which allow neurons to conduct electrical impulses, have altered levels in Fragile X. This state is sometime called a “channelopathy” in the pharma world. This group is studying the effect of specific alterations in ion channels, and potential therapeutic effects of drugs which open and close these channels.
