Research Interests

Influenza A virus is a collective name for a large group of different viruses with variable pathogenic potential for humans; (1) non- or low pathogenic influenza A viruses that infect predominantly avian species, (2) moderately pathogenic viruses that can infect humans and other mammals and finally (3) highly pathogenic influenza A viruses, often referred to as “Bird Flu”, with a case fatality rate of 60%. The mechanism and molecular determinants of virulence and pathogenesis are poorly understood and one of the main questions in the laboratory. We will apply reverse genetics technology to generate novel influenza viruses carrying one or more genes of the more pathogenic strains of influenza. In vitro and in vivo testing of these novel viruses will enable us to identify the molecular markers and mechanisms associated with more severe pathology.

We are also very interested in influenza pathogenesis from the perspective of the host. How does immune status and genetic polymorphisms in essential host genes affect pathology after infection? Finally, we will utilize genetically modified mice to study specific gene function in the context of an influenza virus infection. Viral titers, production of inflammatory mediators and the cellular immune response will be quantified after intranasal infection allowing us to dissect the function of the host protein during an infection.

Finally, we are interested in influenza reassortment. Gene reassortment is a unique evolutionary tool available to segmented viruses, including influenza, allowing efficient transfer of genetic material across different strains of influenza virus. Reassortment has generated many of the past pandemic influenza viruses. Despite its importance, little is known about the mechanism of reassortment, the bottlenecks for the generation of a novel virus and the genetic requirements enabling the mixing of influenza virus genomes.

Jacco Boon, PhD, joined the Division of Infectious Diseases in 2011. He received his PhD from the Erasmus University in The Netherlands in 2003 for his thesis on T-cell mediated immunity to influenza virus. Afterwards he did his Postdoctoral training at St. Jude Children’s Research Hospital in Memphis, TN. His research interests are influenza viruses, including highly pathogenic H5N1, viral pathogenesis and host-pathogen interactions.
