Abstract
To study pathogenic mechanisms of Lyme meningoradiculitis, dorsal root ganglia (DRG) cells and two neuronal cell lines (B50, SH-SY5Y) were incubated with Borrelia garinii, the Borrelia species most frequently isolated from CSF of Lyme neuroborreliosis patients in Europe. We demonstrated that (I) OspA-positive B. garinii adhere to neuronal cells, (II) Borrelia adhesion can be blocked by a monoclonal antibody against OspA, (III) preincubation with proteoglycans interferes with the adhesion process and (IV) rOspA directly binds to the proteoglycans. This indicates that both OspA and the cell bound proteoglycans are involved in the attachment of B. garinii to neuronal cells.
