Jonas Thomsen

During his studies, Jonas Thomsen researched the envelope proteins of Ebola virus, Middle Eastern Respiratory Syndrome (MERS) coronavirus, and Porcine Reproductive and Respiratory Syndrome virus (PRRSV). The envelope proteins mediates the entry of the viral particles and the release of the viral genome into host cytoplasm. Viruses have developed a range of immune evasion strategies in the ever running arms race between pathogens and the host immune system. One of the strategies is downregulation of the host innate immune response. A range of viral proteins have been demonstrated to mediate the modulation of immune response, here amongst a specific conserved domain of the transmembrane subunit of the retroviral envelope protein, named immunosuppressive domain (ISD). Jonas Thomsen has investigated if amino acid substitution mutations in the potential ISDs of Ebola, MERS, and PRRSV envelope proteins will affect the infectivity of the viruses. The aim of the study is to produce hyperimmunogenic proteins for the purpose of the development of new and improved vaccines for the three viruses.


The PhD degree was completed at the Institute of Molecular Biology and Genetic, Science and Technology, Aarhus University.
