Wissenschaftler der Stiftung Tierärztliche Hochschule Hannover (TiHo) und der Medizinischen Hochschule Hannover beschreiben im Fachmagazin PNAS (Proceedings of the National Academy of Sciences of the United States of America, www.pnas.org/content/early/recent) einen bisher unbekannten Mechanismus der Blut-Hirn-Schranke. Die Veröffentlichung erscheint im Lauf dieser Woche. Die Blut-Hirn-Schranke verhindert, dass schädliche Stoff aus der Umwelt oder aus der Nahrung ins Gehirn gelangen können. Sie ist so effektiv, dass sie für Patienten mit einem Hirntumor ein Problem ist: Viele Medikamente können die Barriere nicht überwinden. Für ihre Studie untersuchten die Wissenschaftler die Blut-Hirn- Schranke des Menschen in der Zellkultur. Dafür setzten sie unter anderem fkp Czuxsorhf Tyzpnrkrrmg nli, byy spen zyj izl Clhlruohow xwj Hrewwdl ediygsx tlpl.
