Influenzaviren können für den Menschen gefährlich werden. Darum suchen Wissenschaftler nach Möglichkeiten, die Virusinfektion zu stoppen. Multivalente Inhibitoren, die mit Hilfe zahlreicher Liganden an die Virusoberfläche binden, scheinen dabei besonders vielversprechend zu sein. Wissenschaftler vom Leibniz-Forschungsinstitut für Molekulare Pharmakologie (FMP), der Humboldt-Universität zu Berlin (HU), der Charité, dem Deutschen Rheuma-Forschungszentrum Berlin (DRFZ) und der Freien Universität Berlin (FU) haben jetzt erstmals den multivalenten Ansatz mit Peptiden aus Antikörpern kombiniert. Das Vorgehen hatte Erfolg: In vitro und in vivo Experimente zeigten, dass sich Influenza A Viren zuverlässig mit dem neuen Wirkstoff hemmen lassen.
