Selbst sanfte Berührungen sind für Patienten, die an der "Schmetterlingskrankheit" leiden, der genetisch bedingten Hautkrankheit Epidermolysis Bullosa, äußerst schmerzhaft. Jetzt haben Dr. Li-Yang Chiang, Dr. Kate Poole und Prof. Gary R. Lewin vom Max-Delbrück-Centrum für Molekulare Medizin (MDC) in Berlin-Buch die Ursachen dafür entdeckt. Aufgrund eines genetischen Defekts können die Betroffenen das Strukturmolekül der Haut Laminin-332 nicht bilden, das bei Gesunden die Weiterleitung von Berührungsreizen und die Verzweigung von Nervenzellen hemmt (Nature Neuroscience, doi: 10.1038/nn.2873)*. Dadurch nehmen die Patienten offenbar Berührungen stärker wahr und empfinden sie als schmerzhaft, folgern die MDC-Forscher.
