Trotz weltweit intensiver Forschung ist es bisher nicht gelungen, Impfstoffe gegen humanpathogene Retroviren, wie HTLV und HIV, zu entwickeln. Die klassischen Methoden der Impfstoffentwicklung gegen Viren sind bei Retroviren bisher weitestgehend fehlgeschlagen. Daher müssen neue Ansätze ermittelt werden, um erfolgreich Impfstoffe gegen Retroviren herstellen zu können. Wir verwenden ein Mausmodell, die Infektion von Mäusen mit dem „Friend Murine Leukemia Virus“ (FV), um grundlegende immunologische Mechanismen des Impfschutzes gegen Retroviren aufzuklären. Darüber hinaus untersuchen wir, welche Mediatoren des Immunsystems für die Kontrolle einer chronischen Infektion mit Retroviren wichtig sind. Die Erkenntnisse aus diesen Untersuchungen werden verwendet, um neue Immuntherapien und Impfstoffe gegen HIV zu entwickeln.
