    摘要: The invention provides immunotherapeutic and prophylactic bacteriophage viral-like particle (VLPs) which are useful in the treatment and prevention of human papillomavirus (HPV) infections and related disorders, including cervical cancer and persistent infections associated with HPV. Related compositions (e.g. vaccines), nucleic acid constructs, and therapeutic methods are also provided. VLPs and related compositions of the invention induce high titer antibody responses against HPV L2 and protect against HPV challenge in vivo. VLPs, VLP-containing compositions, and therapeutic methods of the invention induce an immunogenic response against HPV infection, confer immunity against HPV infection, protect against HPV infection, and reduce the likelihood of infection by HPV infection.

    摘要: 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.
