Kann eine Krebsimpfung wirken? Neuer Test gibt Antwort

(PresseBox) (Heidelberg, )
Viele Tumorimpfungen, die derzeit entwickelt werden, sollen das Immunsystem gegen veränderte Proteine der Krebszellen lenken. Jedoch können solche Impfungen nur dann wirken, wenn die Tumorzellen das krebstypisch veränderte Protein passend zurechtgeschnitten dem Immunsystem präsentieren. Wissenschaftler aus dem Deutschen Krebsforschungszentrum und dem Universitätsklinikum Heidelberg beschreiben nun einen Test, mit dem sie diese Grundvoraussetzung für die Wirksamkeit einer Tumorimpfung vorab überprüfen können.

Krebs-Impfungen sollen das körpereigene Immunsystem gezielt gegen Tumorzellen scharf machen. Als besonders erfolgsversprechend gelten Impfungen gegen so genannte Neo-Antigene: Dabei handelt es sich um Proteine, die sich aufgrund einer genetischen Mutation der Tumorzellen von ihren Gegenstücken in gesunden Zellen unterscheiden.
