Lyme borreliosis: a comprehensive approach

Description of Research

The project focuses on Lyme borreliosis (LB) and other tick borne infections and addresses the following questions: Prevalence of ticks and epidemiology of LB and other borrelioses in Finland. Susceptibility of humans to disseminated LB. Pathogenesis of LB including dissemination of LB to the different target organs, the role of borrelia adhesins in this process, and the molecular mechanisms of tissue tropism of borrelia. Molecular and cellular events in the pathogenesis of Lyme neuroborreliosis. Development of novel diagnostics for LB and other borrelioses (e.g. Borrelia miyamotoi infection), including identification of novel biomarkers. Development of PET/CT imaging of LB.
