Abstract:
The invention is directed to virus-like particles (VLPs) of an RNA bacteriophage that (a) comprises a coat polypeptide of said phage modified by insertion of a heterologous peptide that is displayed on said VLP and (b) encapsidates said bacteriophage mRNA as well as populations of these VLPs, and their uses. The invention is further directed to VLPs that encapsidate heterologous substances, as well as populations of these VLPs and their uses.
Abstract:
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.

Abstract:
An immunogen includes an immunogenic carrier and an antigenic apoptosis-associated speck-like protein containing a caspase activation and recruitment domain (ASC) peptide linked to the immunogenic carrier. In one or more embodiments, the immunogenic carrier is a Qβ virus-like particle (VLP). The immunogen may be formulated into a composition useful for treating inflammatory medical conditions.
Abstract:
An immunogen generally includes a virus-like particle and an antigen linked to the virus-like particle. The antigen includes an antigenic portion of a polypeptide, wherein the polypeptide inhibits lipoprotein lipase (LPL) activity by binding to LPL. In some embodiments, the polypeptide is at least a portion of angiopoietin-like 3 (ANGPTL3). In other embodiments, the polypeptide is at least a portion of angiopoietin-like 4 (ANGPTL4). In other embodiments, the polypeptide at least a portion of angiopoietin-like 8 (ANGPTL8). In some embodiments, the virus-like particle is a Qbeta immunogenic carrier. In some of these embodiments, the antigen is linked to the virus-like particle through a Gly-Gly-Gly-Cys linker at the C-terminal of the antigen.
Abstract:
An immunogen includes an antigenic EGFRvIII peptide linked to a Qβ bacteriophage virus-like particle (VLP) carrier. The antigenic EGFRvIII peptide has at least 53%, at least 61%, at least 69%, at least 76%, at least 84%, or at least 92% sequence similarity amino acid similarity to LEEKKGNYVVTDH (SEQ ID NO:1).
