Novel Modulators of Potassium Channels to Treat Fragile X

Novel Modulators of Potassium Channels to Treat Fragile X

With funding from FRAXA, the Yale University team of Leonard Kaczmarek, PhD showed that the firing pattern of suditory neurons in response to repeated stimulation is severely abnormal in fragile X mice. Based on these results, they are collaborating with the UK-based company Autifony to develop advanced compounds which may reverse these deficits.

CRISPR Reactivation of the Fragile X Gene

CRISPR Reactivation of the Fragile X Gene

“We are trying to target the first event that goes wrong in fragile X syndrome”, says Todd, “One reason our previous attempts to develop treatments for fragile X syndrome have failed is that they’ve tried to target the downstream effects of losing the fragile X protein. The protein does many things… bypassing all the functions that it normally takes care of has proven difficult from a pharmacologic perspective.”

Drug Repurposing Study Results Accelerate Progress Towards Fragile X Treatments

Drug Repurposing Study Results Accelerate Progress Towards Fragile X Treatments

While there are over 8,000 rare diseases affecting an estimated 350 million people worldwide, only around 200 of these conditions have effective treatments. Due to the high cost of developing new drugs, rare diseases have historically been less attractive to pharmaceutical companies. Drug repurposing systematically leverages the detailed information available on approved drugs and reduces the time and money needed to deliver safe “new” treatments, but with greater success rates and a potentially more immediate impact on health care.

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

MicroRNA Mediated Astroglial GLT1 Dysregulation in Fragile X

MicroRNA Mediated Astroglial GLT1 Dysregulation in Fragile X

Almost all brain research focuses on neurons – nerve cells. However, the brain has many more glial cells which support, nourish, and protect the neurons. FRAXA Research Foundation awarded a 2017 grant $90,000 to support Dr. Yang’s studies of how changes in glial cells contribute to fragile X syndrome. This grant is funded by a grant from the Pierce Family Fragile X Foundation.

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).
