Wie lagern sich die Strukturproteine des Aids-Erregers HIV zu einer vollständigen Virushülle zusammen? Der Antwort auf diese Frage sind Wissenschaftler des European Molecular Biology Laboratory (EMBL) und des Universitätsklinikums Heidelberg mit Hilfe der hochauflösenden Kryo-Elektronentomographie nun etwas näher gekommen. Sie bildeten das Proteingitter vollständiger, unreifer HI-Viren in einer so hohen, bisher nicht erreichten Auflösung ab, dass die einzelnen Bausteine und ihre Kontakte erstmals deutlich zu erkennen sind. Die neuen Erkenntnisse zur Architektur der Virushülle sind heute online in der Fachzeitschrift "Nature" erschienen.
