Abstract:
Rabies is a viral infection of the central nervous system for which vaccination is the only treatment possible. Besides preexposure, vaccination is highly recommended for people living in endemic areas, veterinarians, and laboratory workers. Our group has developed rabies virus-like particles (RV-VLPs) with immunogenic features expressed in mammalian cells for vaccine applications. In this chapter the methods to obtain and characterize a stable HEK293 cell line expressing RV-VLPs are detailed. Further, analytical ultracentrifugation steps to purify the obtained VLPs are developed, as well as western blot, dynamic light scattering, and immunogold electron microscopy to analyze the size, distribution, shape, and antigenic conformation of the purified particles. Finally, immunization protocols are described to study the immunogenicity of RV-VLPs.
