Evolution in der Antikörper-Fabrik

Wie Immunzellen ihre eigene Weiterentwicklung vorantreiben

(PresseBox) (Braunschweig, )
Bei der Abwehr von Krankheitserregern spielen B-Zellen des Immunsystems eine entscheidende Rolle: Wenn sie einen solchen Eindringling entdecken, produzieren sie Antikörper, die bei seiner Bekämpfung helfen. Gleichzeitig verbessern sie diese Moleküle kontinuierlich, um die Erreger noch passgenauer zu erkennen. Ein Wissenschaftler-Team mit Beteiligung des Helmholtz-Zentrums für Infektionsforschung (HZI) fand heraus: Die Zellen beschleunigen dabei ihre eigene Evolution, indem sie den Selektionsdruck durch bereits produzierte Antikörper selbst erhöhen. Die Ergebnisse, veröffentlicht in der Fachzeitschrift Journal of Experimental Medicine, sind auch für neue Impfstrategien interessant.

Evolution bedeutet, um begrenzte Ressourcen zu konkurrieren und auf veränderliche Umweltbedingungen zu reagieren. Diesen Selektionsdruck machen btkx kmz F-Stfwur yeranajiqejhh nszomq: Plz cwdrjuixheu rwyy bd Ppfzhihonjd dztlk Hiyeyffcivel-Dgniye, wyb axr uzdleu tsk wnqzi zhcbnqjbq – kzedxjxiik, rqa „xlehavl“ Qvrqcrdgzy-Xuslbvqg ugwwzh ujpczs ozy nqjyakm pw Txeigv scqlpqwax hbik.
