Morbus Charcot-Marie-Tooth (CMT) ist die häufigste Form von erblichen Neuropathien. Durch eine genetische Mutation wird die isolierende Myelinschicht der peripheren Nerven nach und nach geschädigt, was beispielsweise beim CMT-Typ 4B zu schwersten Behinderungen führt. Da die molekularen Grundlagen weitgehend unbekannt sind, ist dieser CMT-Typ bis heute weder behandelbar noch heilbar. Doch jetzt konnten Wissenschaftler vom Leibniz-Forschungsinstitut für Molekulare Pharmakologie (FMP) in Berlin gemeinsam mit Kollegen aus Mailand, Paris und Mexiko einen neuen molekularen Mechanismus aufzeigen: Demnach kommt dem Protein Rab35 und dem, von diesem regulierten mTOR Signalweg eine zentrale Rolle bei der Myelinscheidenformation im peripheren Nervensystem zu.
