Wer die kaum zu überblickende Flut von Medikamenten in den Apotheken betrachtet, dem fällt es schwer, an einen Medikamentenmangel zu glauben. Doch nach wie vor können viele Infektionskrankheiten oder auch Krebs nur unzureichend behandelt werden. Bei der medikamentösen Behandlung ist es besonders wichtig, dass der Wirkstoff im Körper auch an den richtigen Ort gelangt. Lesen Sie hier, wie die Abteilung „Wirkstoff-Transport“ an der korrekten Verteilung neuer Arzneimittel im Körper forscht.

    III. Research Interests

    The main focus of research of Prof. Lehr’s team over the past 15 years has been on the one hand exploring biological barriers - in particular of the gastro-intestinal tract, the skin and the lungs -, and on the other hand developing the appropriate carriers capable of crossing these epithelial barriers to deliver an active molecule to its target. The expansion of this approach by developing new in vitro models of higher sophistication and relevance, based on the epithelial cells and tissues concerned, is in advanced progress. In parallel, the nanotechnology approach is improving and broadened in terms of formulating multifunctional nanocarriers that allow targeting the site of action, release the payload in a controllable manner and last but not least being safely biodegraded and excreted from the body.

  • Kleine Teile – große Wirkung: Pharmazeuten des HIPS schleusen Medikamente zielsicher durch den Körper
    Wie kommt ein Medikament dahin, wo es wirken soll? Das ist eine der zentralen Fragen bei der Entwicklung neuer Wirkstoffe. Denn es reicht nicht, ein tolles neues Medikament gegen Darminfektionen im Reagenzglas zu haben – es muss auch dort hin gelangen, wo die Krankheit stattfindet. Mit Transportmolekülen schleusen die Pharmazeuten des HZI diese Wirkstoffe durch unseren Körper – über Barrieren, durch passende Lücken und an gefährlichen Stellen vorbei.
