Neue Forschungsergebnisse – Sicherheit von kurzzeitig kultivierten CAR-T-Zellen in der Krebsimmuntherapie

(PresseBox) (Langen in Hessen, )



CAR-T-Zellen bieten eine neue Behandlungsoption für bestimmte Formen von Blutkrebs.
Ein Problem dieser individuell für jede Patientin und jeden Patienten erzeugten Immunzellen ist die lange Dauer der Herstellung.
Eine neue Methode erlaubt eine schnellere Herstellung der CAR-T-Zellen. Unklar ist aber das Sicherheitsprofil dieser Zellen, insbesondere im Hinblick auf die Entstehung des Zytokinfreisetzungssyndroms (CRS).
Ein Forschungsteam des Paul-Ehrlich-Instituts hat ein leicht zugängliches Mausmodell sowie einen zellbasierten Test entwickelt, mit dem das Risiko abgeschätzt werden kann.
Die Forschenden stellten fest, dass die Kurzzeit-CAR-T-Zellen im Vergleich zu herkömmlichen CAR-T-Zellen eine deutlich stärkere CRS-Induktion vermitteln, was bei klinischen Anwendungen berücksichtigt werden sollte.
