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. These brief updates from researchers investigating fragile X.
According to Dr. Erickson, AZD7325 is a drug that selectively boosts GABA neurotransmission in the brain. GABA is the primary neurochemical in the brain that blocks brain activation. GABA activity is in balance in the brain with Glutamate activity, which is the primary neurochemical that causes brain activation. In fragile X, GABA activity is insufficient and glutamate activity is excessive, likely causing brain activity to be out of balance. AZD7325 attempts to correct parts of this imbalance by boosting the insufficient GABA activity in the brains of people with fragile X
With a $51,000 grant from FRAXA Research Foundation, Dr. Craig Erickson will conduct a double-blind, placebo-controlled clinical trial of AZD7325 in adults with fragile X syndrome at Cincinnati Children’s Hospital. The compound being studied is an investigational new drug from AstraZeneca that targets GABA (A) receptors.
With $258,000 in grants since 2013 from FRAXA Research Foundation, Dr. Anis Contractor and Dr. Qionger He at Northwestern University are exploring the potential of the available drug bumetanide to correct altered GABA signalling in a mouse model of fragile X syndrome.
