Neue Genfähren für den gezielten Gentransfer in T-Lymphozyten der Maus

(PresseBox) (Langen in Hessen, )
Wissenschaftlerinnen und Wissenschaftler des Paul-Ehrlich-Instituts (PEI) haben gleich zwei neue Wege aufgezeigt, mittels viraler Genfähren effektiv Gene in zytotoxische T-Zellen (Cytotoxic T Lymphocytes, CTL) der Maus zu transferieren. CTL gehören zu den weißen Blutkörperchen und werden auch als Killerzellen bezeichnet. Die neuen Werkzeuge haben das Potenzial, präklinische Untersuchungen für Gentransferarzneimittel im immuntherapeutischen Bereich zu erleichtern. Zudem hat die Arbeit auch weiterreichende Relevanz für die Gentherapie: Sie beschreibt eine neue Klasse von viralen Genfähren, genannt DART-AAV, die Zielzellen besonders präzise treffen.

Gentherapeutika fügen Erbinformation in Körperzellen einer Patientin oder eines Patienten ein, um einen therapeutischen Nutzen zu erzielen.
