Brain Imbalance Target of Dr. Erickson’s New Clinical Trial

Brain Imbalance Target of Dr. Erickson’s New Clinical Trial

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

Defining the Subcellular Specificity of Metabotropic Glutamate Receptor (mGluR5) Antagonists

Defining the Subcellular Specificity of Metabotropic Glutamate Receptor (mGluR5) Antagonists

With $217,500 in grants from FRAXA Research Foundation, Dr. Karen O’Malley and team studied the function of mGluR5 when it is inside cells. Many of the symptoms of fragile X Syndrome (FXS) are thought to arise due to overactive metabotropic glutamate receptor 5 (mGluR5) signaling, which is normally opposed by the protein missing in FXS, Fragile X Protein (FMRP).

Neural Markers of Fragile X: A Powerful New Tool for Clinical Trials

Neural Markers of Fragile X: A Powerful New Tool for Clinical Trials

Once the neural marker is identified for a particular challenge, such as kids with poor language versus good language, neural markers can be measured during drug and behavioral therapy trials to see if a child is improving based on objective biological measures.
