Bakterien- und Virendetektor alarmbereit am Einsatzort

Forscher zeigen: Ein ausgereiftes Transportsystem hilft Immunzellen, Infektionen schnell zu erkennen

(PresseBox) (Braunschweig, )
"Gefahr!", signalisiert der molekulare Detektor mit dem Namen TLR9, wenn er bakterielle oder virale Erbinformation, die DNA, erkennt. Dann leitet das Immunsystem die Bekämpfung der Infektion ein. Dieser erste Schutz funktioniert schnell, weil er grundlegende Strukturen der Eindringlinge erkennt - in diesem Fall die DNA der Bakterien oder Viren. Forscher des Helmholtz-Zentrums für Infektionsforschung (HZI) haben gezeigt, dass TLR9 fremde DNA nicht nur rasch erkennt, sondern bereits einsatzbereit dort wartet, wo er auf sie treffen wird.

Durch Mechanismen wie diesen gewinnen wir wertvolle Zeit, bevor der zwar effektivere, aber langsamere Teil des Immunsystems, das erworbene Immunsystem, angeschaltet wird. Was notwendig
