Slack Potassium Channel Inhibitors to Normalize FMR1 Knockout Mice
Learn how a $100,000 FRAXA research grant supports Yale researchers in using Slack potassium channel inhibitors to treat Fragile X syndrome by normalizing behaviors in FMR1 knockout mice.
Read moreNovel Modulators of Potassium Channels to Treat Fragile X
With funding from FRAXA over 2015-2017, the Yale University team of Leonard Kaczmarek, PhD showed that the firing patterns of auditory 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.
Read moreInhibitors of STEP as a Novel Treatment of Fragile X Syndrome
With a $349,000 grant from FRAXA Research Foundation from 2008-2015, Dr. Paul Lombroso and his team at Yale University researched if inhibiting STEP could reduce behavioral abnormalities in Fragile X syndrome. Results published.

Scientists have found increases in the numbers of neurons in brain regions of autistic children, suggesting a problem in developmental programmed cell death pathways. One of the most important effectors of neuronal survival during brain development is the “anti-cell death” protein Bcl-xL. While the normal function of Bcl-xL is to maintain a healthy number of neurons and synapses, over-expressed Bcl-xL can cause an overabundance of synaptic connections. This may be happening in Fragile X.

With $246,000 in funding from FRAXA over 2012-2014, the Yale University team of Leonard Kaczmarek, PhD, showed that loss of FMRP leads to an increased Kv3.1 potassium currents and decreased Slack potassium currents in neurons. Both of these changes impair timing of action potentials in auditory neurons (and likely others throughout the brain). The team also found that the firing pattern of 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 and test advanced compounds which may reverse these deficits.

With $80,000 in funding from FRAXA over several years, the Yale University team of Leonard Kaczmarek, PhD showed that loss of FMRP leads to an increased Kv3.1 potassium currents. This change impairs timing of action potentials in auditory neurons (and likely others throughout the brain).
