Große Moleküle in lebende Zellen transportiert: Forscher erzielen Durchbruch ins Zellinnere

(PresseBox) (Berlin, )
Es ist eine der großen pharmakologischen Fragen: Wie bringt man große funktionale Biomoleküle wie Proteine oder Antikörper in eine Körperzelle? Die Verknüpfung mit zellpenetrierenden Peptiden ist ein vielversprechender Weg – hat bislang jedoch noch nicht durchweg zu den erhofften Ergebnissen geführt. Jetzt präsentieren Forscher vom Leibniz-Forschungsinstitut für Molekulare Pharmakologie (FMP) in Berlin und der TU Darmstadt eine neue Lösung: Befestigt man diese Peptide zusätzlich an der Zelloberfläche, klappt es mit dem Transport ins Zellinnere um vieles besser. Die bahnbrechenden Ergebnisse sind soeben im Fachmagazin „Nature Chemistry“ erschienen.

Unser Zellinneres ist aus gutem Grund durch eine Zellmembran vor unerwünschten Besuchern geschützt.
