MD PhD K.C. Wolthers (Molecular epidemiology and pathogenesis of human picornaviruses)

Our clinical laboratory is specialized in fast and reliable laboratory diagnosis for entero- rhino- and parechovirus infections, all members of the Picornavirus family. We use virus genotyping to show the widespreadness of the different virus genoypes and their relation with clinical symptoms. We have expertise in molecular evolution studies. My research established the role of human parechoviruses (HPeVs) as serious and frequently occurring pathogens in young infants, and two new types HPeV4 and HPeV14 were discovered. We defined classification rules for HPeVs in good agreement with the Picornavirus Studygroup; nowadays, 19 types are known. We were the first to show significant differences in clinical symptoms and age of infection between HPeV3 and HPeV1, and the importance of HPeV3 in viral CNS infections.

My research focuses on pathogenesis of human picornaviruses. The role of maternal antibody protection in picornavirus infection in neonates is studied, as well as differences in cell tropism between picornavirus types in relation to disease severity. Furthermore we focus on treatment possibilities and resistance mechanisms. My group has extensive expertise in virus culture and human 3D cell culture models, such as human airway epithelium (HAE) cultures and gut organoids, which are used to study picornavirus pathogenesis.  

I am (co) coordinator of the Marie Curie ITN consortium Organovir, a trainingsnetwork on Organoids for Virology (www.organovir.com). The coming years we will extend our expertise with 3D models and organoids such as human brain and skin for virus research.
