Research Points to Drugs which Inhibit PDE to Treat Fragile X

Research Points to Drugs which Inhibit PDE to Treat Fragile X

FRAXA Research Foundation funded a grant of $90,000 over 2016-2018, for a postdoctoral fellowship for Thomas Maurin, PhD, working under the mentorship of Dr. Barbara Bardoni at INSERM in France.

Auditory Dysfunction in Fragile X Syndrome, Role for the Sound Localization Pathway

Auditory Dysfunction in Fragile X Syndrome, Role for the Sound Localization Pathway

FRAXA Research Foundation has renewed Dr. Elizabeth McCullagh’s 2017 FRAXA Fellowship for a second year. Dr. McCullagh and Principal Investigator Dr. Achem Klug are investigating the “cocktail party effect” in Fragile X mice.
