Insect infection and immunity
Lab Webpage: http://www.eleftherianoslab.org
We investigate host-pathogen interactions using a model insect (Drosophila), a nematode parasite (Heterorhabditis) and its symbiotic insect-pathogenic bacterium (Photorhabdus). This is a very powerful system with the great advantage that all three players of the interaction can be genetically manipulated. RNA interference in the insect and nematode combined with bacterial genetics can be readily applied to investigate the molecular and evolutionary basis of insect immunity, bacterial symbiosis and nematode parasitism as well as the complex interactions between these biological processes. In addition all three genomes (Drosophila, Heterorhabditis and Photorhabdus) are sequenced, which allows very elegant studies on gene-to-gene-interactions.
- Which genes the bacteria use to infect and persist in the fly?
- What immune mechanisms are activated in the fly in response to infection by the nematode and/or the bacteria?
- How does the nematode cope with the fly immune system?
We use a mix of molecular biology, basic microbiology and parasitology, cellular immunology, insect physiology/biochemistry, Drosophila genetics, insect and microbial genomics as well as immunohistochemistry techniques.
