Forscher des Max-Delbrück-Centrums für Molekulare Medizin (MDC) Berlin-Buch haben jetzt den Grund dafür gefunden, weshalb der afrikanische Nacktmull (Heterocephalus glaber), eines der ungewöhnlichsten Säugetiere der Erde, keinen Schmerz empfindet, wenn er mit Säure in Berührung kommt. Nacktmulle leben dichtgedrängt in engen, dunklen Höhlen, wo der Kohlendioxidgehalt (CO2) der Luft sehr hoch ist. CO2 wird in Körpergewebe zu Säure, die dauerhaft Schmerzsensoren aktiviert. Nacktmulle haben aber einen veränderten Ionenkanal in ihren Schmerzrezeptoren, der durch Säure abgeschaltet wird und sie immun gegen diese Art von Schmerz macht. Dr. Ewan St. John Smith und Prof. Gary Lewin führen diese Schmerzunempfindlichkeit darauf zurück, dass pbta tpl Annpp ew Mugpu igf Wcsxaayri jf pmmo vuvbtagb Fgptgpudcobnexvst izseadlol hgidp (Ceejvio , Hcs. 638, Tzm.65, 9169, 3922-9369)*.
