Course Overview:

    One lecture will be given by an instructor on each Tuesday and follow-up papers chosen by the instructor will be presented by students on Thursday of the same week. Students will be graded on their class participation and paper presentation.

    In this course we will explore host and viral pathogen evolutionary relationships. We will consider several examples of the effects of virus epidemics on viral and host genetics. We will discuss environmental experiments human use of

    viruses as a means to control animal populations.

    We will challenge dogma by considering whether directionality of gene flow between virus and host supports the concept that viruses contribute a large degree of host genetic diversity.

    We will discuss the origins of viruses starting from the “RNA World” and we will discuss systems to model RNA and DNA virus evolution in the lab. An important topic will be evolution of HIV: escape from immunologic pressure directed at neutralizing epitopes or from drug selection; evolution of HIV quasi-species. We will also consider whether viruses can evolve toward increased pathogenicity instead of attenuation. We will revisit examples of Influenza rapid evolution relevant to the current Avian flu threat.

    Plant and Algal viruses will allow us to explore not only host/virus defense relationships but to consider whether theories that complex viruses gave rise to eukaryotic organelles is supported.
