The interaction between CD200 and its inhibitory receptor CD200R is known to transmit an inhibitory signal to immune cells that express CD200R. The acquisition of genes that are similar to cd200 by viruses contributes to an effective host immune evasion. RCMV e127 has been described as a homologue of rat CD200 and is able to bind CD200R. The aim of this thesis was to examine if e127 is a functional homologue. In conclusion, this work supports the growing importance of viral CD200 homologues in immune evasion and provides an animal model to study the impact of viral CD200 homologues on the anti-viral immune response.

Die Herstellung von biogenen Metallnanopartikeln ist ein sich entwickelnder Bereich der Nanobiotechnologie, der wirtschaftliche und potenziell umweltfreundliche Vorteile gegenüber herkömmlichen chemischen und physikalischen Synthesemethoden bietet. Sobald Nanomaterialien (NM) in das Gewebe von Organismen eindringen oder durch die Zellmembranen transportiert werden, tritt die Toxizität wahrscheinlich hauptsächlich durch einen oder eine Kombination von vier Mechanismen auf. Die potenzielle Anwendung von Au-Nanopartikeln in der Biomedizin wirft zunehmend Fragen zu möglichen Risiken für die menschliche Gesundheit und die Umwelt auf. Diese Studie richtet sich an Forscher, Wissenschaftler und Pharmazeuten in den Bereichen Nanobiotechnologie, Pharmazeutik und Chemieingenieurwesen, Arzneimittelentwicklung, Arzneipflanzen und pharmazeutische Nanotoxikologie.

Die Biosynthese von Goldnanopartikeln (AuNPs) als antimikrobielles Mittel wird anhand eines umweltfreundlichen Verfahrens mit wässrigem Extrakt von Bockshornkleesamen untersucht.
