Abstract
Recombinant nodavirus related compositions are disclosed. These compositions include chimeric proteins in which a nodavirus capsid protein is present together with a heterologous peptide segment. The heterologous peptide includes at least one cell-specific targeting sequence, such as a B cell epitope, a T cell epitope, or a sequence specific for another cell type, such as a hepatocyte. The chimeric proteins can be assembled to form chimeric virus-like particles. The chimeric virus-like particles are useful in therapeutic applications, such as vaccines and gene-delivery vectors, and in diagnostic applications, such as kits for the testing of body tissue or fluid samples. Methods for the use of recombinant nodavirus related compositions in therapeutic and diagnostic applications are also described.
Claims24
A chimeric protein which comprises a Flock House virus capsid protein free from deletions, having a core structure constituted by anti-parallel beta barrels, and a heterologous peptide segment in a loop formed by said capsid protein in the region between beta-E and beta-F strands on one of said beta barrels.
A chimeric protein which comprises a Flock House virus capsid protein free from deletions and including a heterologous peptide segment in the region between amino acid residues 205 and amino acid residue 209 from the amino terminus of said capsid protein, wherein said chimeric protein can assemble into a virus-like particle.
