Researchers of the Max Delbrück Center for Molecular Medicine (MDC) Berlin-Buch have now identified and described a molecular mechanism underlying the most common malformation of the brain in humans. In holoprosencephaly (HPE), the forebrain (prosencephalon) is only incompletely formed. Here a binding site (receptor) for cholesterol plays a key role. If this receptor is defective, specific signals cannot be received, and the forebrain cannot separate into two hemispheres, as Dr. Annabel Christ, Professor Thomas Willnow and Dr. Annette Hammes have now shown in mice.
