    Abstract: The invention is directed to methods of screening immunogenic viral like particles and related immunogenic compositions and diagnostic techniques. In one embodiment, the invention provides methods of screening immunogenic viral like particles containing peptides corresponding to epitope regions of a wide variety of pathogens, including viruses, bacteria, parasites, and microbes. Non-infectious antigens and allergens of interest can also be screened as described herein. Immunization, therapeutic and diagnostic applications are also described for the compositions and methods according to the invention. In another embodiment, the invention provides novel methods of identifying a cryptic neutralizing epitope and related vaccines, constructs, and libraries. In some embodiments, these methods use high-throughput formats that are facilitated by in silica or in vitro steps.

    Abstract: The present invention relates to a system and method for controlling peptide display valency on virus-like particles (VLPs), especially including MS2 VLPs. In this method, large amounts of wild-type and low quantities of single-chain dimer coat proteins may be produced from a single RNA. Valency is controlled in immunogen (vaccine) production by providing a system that allows the production of large amounts of wild-type and low quantities of single-chain dimer coating proteins from a single RNA, allowing facile adjustment of display valency levels on VLPs, especially MS2 VLPS over a wide range, from few than one- on average- to as many as ninety per particle. This facilitates the production of immunogens and vaccines, including VLPs exhibiting low valency. Nucleic acid constructs useful in the expression of virus-like particles are disclosed, comprised of a coat polypeptide of MS2 modified by insertion of a heterologous peptide, wherein the heterologous peptide is displayed on the virus-like particle and encapsidates MS2 niRNA. Nucleic acid constructs are also disclosed which are useful in the expression of virus-like particles comprised of a coat polypeptide of PP7 modified by insertion of a heterologous peptide, wherein the heterologous peptide is displayed on the virus-like particle and encapsidates PP7 mRNA.
