Identification and characterization of cellular receptors for lymphotropic measles virus strains and investigation of the role of viral envelope proteins for tropism and virulence
Project management at the University of Würzburg:
Tropism and virulence of measles virus (MV) are determined largely by the utilization of certain cellular receptors. Also the MV-induced proliferation-inhibition of lymphocytes is a receptor-mediated phenomenon, which depends on the viral envelope proteins. CD46, which was identifyed a a receptor for MV-vaccine strains, does not direktly influence the proliferation inhibition. We succeeded in isolating several monoclonal antibodies inhibiting the infection of cells with wildtype MV-strains. One monoclonal antibody (mAb 5C6) recognizes CD150, a receptor of activated lymphocytes, monocytes, and dendritic cells.Interaction of this surface molecule could contribiute to the virally induced immunosuppression. In addition, there exist good animal models (mice and rats) for the MV-induced central nervous system diseases. We began to clone recombinant viruses to elucidate the molecular determinants of neurovirulence of MV-variants in animal models and tissue culture.
