Tumortherapie ohne Leberschaden: "Therapeutisches Fenster" für TRAIL/Bortezomib

(PresseBox) (Heidelberg, )
Der körpereigene Botenstoff TRAIL treibt Krebszellen in den Tod, ohne dabei gesunden Zellen zu schaden. Tumorzellen entwickeln jedoch oft Resistenzen gegen die Todesbotschaft. Für einen Einsatz in der Krebstherapie wird TRAIL daher mit Substanzen kombiniert, die Tumorzellen resensibilisieren, etwa mit dem Krebsmedikament Bortezomib. Wissenschaftler des Deutschen Krebsforschungszentrums zeigten nun, dass die Kombination TRAIL/Bortezomib in hoher Dosierung leberschädigend wirkt. Gleichzeitig jedoch fanden sie ein "therapeutisches Fenster" für den Einsatz der Kombitherapie - einen Dosisbereich, in dem Tumorzellen sensibilisiert, Leberzellen aber nicht geschädigt werden.

Krebszellen gezielt in den Tod zu treiben, ohne dabei gesunde Zellen in Mitleidenschaft zu ziehen, ist das Zwhwrpnks lzqex Zxltxpqkurekgxw.
