Studies have shown that the function of inhibitory networks is disturbed in Fragile X. This abnormality is not well understood but appears to be secondary to abnormalities in metabotropic glutamate and endocannabinoid systems. With a $90,000 grant from FRAXA, Dr. Molly Huntsman’s team examined how these networks interact and how inhibitory deficits can best be remedied.Read more
Molly Huntsman, PhD, Associate Professor at the University of Colorado, researches how inhibitors in neurotransmissions affect neurodevelopmental disorders.
GABAergic Inhibitory Function in Fragile X Syndrome
With a $100,000 grant from FRAXA Research Foundation, Drs. Joshua Corbin and Molly Huntsman from the Children’s National Medical Center examined the role of a particular class of brain cells (inhibitory interneurons) that dampen excessive activity in the “emotional center of the brain” (the amydala). This inhibition is deficient in Fragile X, and so they are looking for ways to remedy this. This is particularly interesting to parents of children who are overly anxious and emotional. They worked with Dr. Walter Kaufmann, a clinician at Kennedy Krieger Institute in Maryland.Read more
