Kleine, kelchförmige Eiweißstoffe (Lipocaline) in Tränen und Blut schützen uns vor Krankheitskeimen und transportieren Vitamine und Hormone. Forscher der TU München (TUM) und der TUM-Biotech-Ausgründung "Pieris" haben diese Lipocaline jetzt so verändert, dass sie in der Krebsbehandlung helfen könnten - als Alternative zu den weltweit etablierten therapeutischen Antikörpern. Darüber berichten die Wissenschaftler in den beiden renommierten Zeitschriften "Proceedings of the National Academy of Sciences of the U.S.A." und "Journal of the American Chemical Society".
Das Spurenelement Eisen ist für fast alle Organismen lebenswichtig. Viele Bakterien legen daher nach einer Infektion eine Art chemischen Miniköder (Siderophor) aus, der Eisen-Ionen in den Ryfxmykuitkatduvqzy bwcgants.
