Research interests:
1. Evolution of the vertebrate’s immune system
I am convinced that there is no applied science without fundamental science! We need to keep on addressing fundamental questions on the vertebrate’s immune system before we can apply this knowledge for future vaccine development. For example, do fish have Th1, Th2, Th17, Treg cells? How does the heterothermic nature of fish influence the quality and magnitude of their (memory) immune response? Is the biological activity of immune mediators (cytokines, chemokines, etc) conserved throughout evolution? Etc…
2. host-pathogen interaction and vaccine development
In chicken, we study anti-viral immunity against infectious bronchitis virus (IBV) infection, a major burden in the poultry industry. In particular, we focus on the chicken type-I IFN response and immune evasion strategies by IBV.
In cyprinid fish, we mainly focus on immune responses to viral and parasitic infections. In particular, we study the immune response of carp and/or zebrafish to spring viraemia of carp virus (SVCV), koi herpes virus (KHV) and trypanosome infections.
Furthermore, we recently established a ‘sleeping sickness’ (trypanosomiasis) infection model in zebrafish and we are able to follow in real-time, in vivo, the kinetics of host-pathogen interaction; such model is unique and will help unravel mechanisms that have never been visualised, not even in mammals. https://elifesciences.org/articles/48388
With respect to vaccine development, we focus on nucleic acid-based (DNA/RNA) vaccines and recombinant viral vectors. Recombinant live attenuated viruses may be cumbersome to produce but often give excellent protection. DNA vaccines represent third generation vaccines and have proven very effective in fish. We recently reported on the first DNA vaccine against SVCV, which confers full protection to juvenile carp when administered by injection. Finding alternative route of vaccine administration, e.g. orally or by bath, is very important because the injection of individual fish is not always stress-free, nor cost-effective.
