| Description | Entomopathogenic nematodes and their associated bacteria comprise together highly pathogenic complex able to invade and kill insect host within two days. Both bacteria and nematodes produce variety of factors interacting with insect immune system that help to overcome host defences. The tripartite model (Drosophila, nematodes, bacteria) was established and used to show an immune function for candidate genes using different Drosophila mutants or RNAi lines with defects in clotting or other branches of the immune system. We demonstrated an immune function during nematode infection for known clotting enzymes and substrates, recognition molecules, eicosanoids etc. In conclusion, we show that the Heterorhabditis/Photorhabdus infection model is suitable to identify novel regulators of innate immunity and we bring evidence of coagulation immune function in insects against nematode infection. Our research is supported by research grants from the Swedish Foundation for International Cooperation in Research and Higher Education (STINT) and by grant from Ministry of Agriculture of Czech Republic (NAZV-KUS QJ1210047). |
