Bei der Alzheimer Krankheit lagern sich Proteine zu langen Fibrillen zusammen. Dies führt zum Absterben der Nervenzellen. Kleine Hitzeschock-Proteine wirken dem entgegen. Wissenschaftler hoffen daher, sie als Wirkstoffe zur Behandlung neurodegenerativer Krankheiten einsetzen zu können. Am Beispiel eines kleinen Hitzeschock-Proteins haben Forscher der Technischen Universität München (TUM) und des Helmholtz Zentrums München nun herausgefunden, wie das Protein andere Proteine bindet. Die Forschungsarbeiten wurden gefördert vom Helmholtz-Zentrum München und der Deutschen Forschungsgemeinschaft (DFG) (SFB-1035 und Exzellenzcluster „Center for Integrated Protein Science Munich“ (CIPSM). Begonnen wurden die Arbeiten am Leibniz-Institut für Molekulare Pharmakologie (FMP) in Berlin.
Kleine Hitzeschockproteine sind die „Katastrophenhelfer“ der Rttao.
