  • Publication number: 20130052216
    Abstract: The present invention provides particle-forming chimeric proteins comprising a Calicivirus capsid protein and one or more heterologous antigen sequences. In particular, the present invention discloses engineered Calicivirus capsid protein sequences containing heterologous epitopes fused at internal locations such that the modified capsid proteins retain the ability to form virus-like particles when expressed in host cells. Virus-like particles comprising the chimeric proteins and vaccine formulations are also described.

  • Publication number: 20120093855
    Abstract: The present invention relates to the field of isolation of enveloped virus-based virus-like particles (VLPs) free of infectious agents. In preferred examples, the field includes methods of inactivation of infectious agents that do not adversely affect the immunogenicity of the enveloped virus-based VLPs. In certain embodiments, the enveloped virus-based VLPs are produced in insect cell based expression systems.

  • Publication number: 20110195113
    Abstract: The present invention provides polypeptides having a composite amino acid sequence derived from a consensus sequence representing the capsid proteins of two or more circulating strains of a non-enveloped virus. In particular, the invention provides virus-like particles comprising at least one composite polypeptide. Such virus-like particles have antigenic epitopes of two or more circulating strains of a non-enveloped virus and produce an increase in antisera cross-reactivity to one or more circulating strains of the non-enveloped virus. Methods of making composite virus-like particles and vaccine formulations comprising composite virus-like particles are also disclosed.
