Disclosed is a new class of conjugated virus-like particles (VLPs). These conjugated VLPs bind a wide variety of tumors and comprise epitopes recognized by a prior T cell immune response already existing in a host. These epitopes are derived from pathogens or previous vaccinations (such as early childhood vaccines). This provokes the body's pre-existing cytotoxic immunity obtained through previous infection or previous childhood vaccination to be redirected to the tumor cells for the elimination of cancer, and form long-term anti-tumor immunity. The described conjugated VLPs are useful for tailoring a broad range of tumors towards a response from existing immunity circumventing the need to identify tumor antigens or generate tumor-specific immune responses. Importantly, the compositions and methods described herein broadens opportunities for treatment for all cancer types in subjects who previously had un-targetable cancers due to various technological and biological limitations of currently available immuno-therapeutic drugs.

The invention provides human papillomavirus (HPV) antigen formulations which show increased antigen stability. More specifically, the invention provides stable HPV formulations comprising HPV virus-like particles (VLPs) bound to an aluminum salt adjuvant and further comprise a combination of sucrose and mannitol. The vaccine formulations of the invention are stable following freeze-thaw and freeze-drying. Also provided are lyophilized and frozen HPV vaccine formulations comprising HPV VLPs of at least one HPV type adsorbed onto an aluminum salt adjuvant, sucrose, and mannitol. Methods of making the stable vaccine formulations of the invention are also provided.

Provided are a mutated HPV58 L1 protein or a variant thereof, a sequence encoding the same, a method for preparing the same, and a virus-like particle comprising the same, wherein the protein or a variant thereof and the virus-like particle can induce the generation of neutralizing antibodies against at least two HPV types, and therefore can be used to prevent infection by said at least two HPV types, and a disease caused by said infection, such as cervical cancer and condyloma acuminatum. The invention further relates to the use of the protein and the virus-like particle in the manufacture of a pharmaceutical composition or a vaccine for preventing infection by said at least two HPV types, and a disease caused by said infection, such as cervical cancer and condyloma acuminatum.

Compositions and treatments for inducing tumor regression by activating inflammasomes in tumor cells and tumor-associated cells. A tumor in a subject is treated by administering a composition to the subject that activates inflammasomes in cells of the tumor and thereby causes tumor cell pyroptosis and tumor regression.

The present disclosure is directed to methods and compositions for the diagnosis and/or treatment of tumors, such as ocular tumors, using virus-like particles conjugated to photosensitive molecules.

The invention relates to a virus like particle (VLP) based vaccine. The virus-like particle constitutes a non-naturally occurring, ordered and repetitive antigen array display scaffold which can obtain a strong and long-lasting immune response in a subject. The VLP based vaccine may be used for the prophylaxis and/or treatment of a disease including, but is not limited to, cancer, cardiovascular, infectious, asthma, and/or allergy diseases/disorders.

This invention relates to chimeric virus-like particles (VLPs) assembled from a polypeptide comprising a papilloma p virus (PV) L1 protein or L1/L2 protein and a target peptide comprising a CD8+ T cell epitope derived from a human pathogen. This invention also relates to methods using the chimeric VLPs as antigen-specific redirectors of immune responses.

The present disclosure is directed to methods and compositions for the diagnosis and/or treatment of tumors, such as ocular tumors, using virus-like particles conjugated to photosensitive molecules.

The present invention relates to prophylactic and/or therapeutic vaccines that contain Newcastle disease Virus (NDV) virus-like particles (VLPs) comprising one or more Epstein-Barr Virus (EBV) antigens. In one embodiment, the invention provides a recombinant virus-like particle (VLP) comprising, in operable combination, a) Newcastle disease virus (NDV) matrix (M) protein, and b) one or more Epstein-Barr Virus (BBV) antigens. The invention's prophylactic and/or therapeutic vaccines are useful for preventing and/or treating infection with EBV and/or disease associated Epstein-Barr Virus, such as cancer.

The invention relates to a truncated L1 protein of the Human Papillomavirus Type 11, a virus-like particle consisting of the protein, a vaccine comprising said virus-like particle, and the use of the vaccine in the prevention of condyloma acuminatum or HPV infections.
