The present disclosure relates to, inter alia, a method for treating a tumor by intratumorally delivering an effective amount of a composition comprising an expression vector that comprises a first nucleotide sequence encoding a secretable vaccine protein, and a second nucleotide sequence encoding a T cell costimulatory fusion protein.

The present invention relates to the prophylactic and therapeutic vaccine against HPV and cancers associated with the virus, aimed at people seeking prevention or those already infected with HPV who have developed cancer. It also refers to DNA expression vectors that can efficiently produce the L2 protein of the HPV16 virus capsid, in addition to the viral E6 oncoprotein associated with human papillomavirus tumors. In particular, this invention relates to obtaining recombinant fusion or hybrid proteins, through gene cloning into expression vectors, produced by the genetic translation of fused genes, formed by the combination of nucleic acid regulatory sequences of one or more genes, with the protein coding sequences of one or more genes, used to generate two distinct types of responses: lasting humoral immune response, capable of stimulating the production of specific anti-L2 and anti-E6 antibodies against HPV (prophylactic action), as well as activate the cellular immune response, to fight tumor cells and induce the expression of TNF cytokines (Tumor Necrosis Factor) or Tumor Necrosis Factor (therapeutic action).

GLP-2 analogues are disclosed which comprise one of more substitutions as compared to [hGly2]GLP-2 and which improved biological activity in vivo and/or improved chemical stability, e.g., as assessed in in vitro stability assays. More particularly, preferred GLP-2 analogues disclosed herein comprise substitutions at one or more of positions 8, 16, 24 and/or 28 of the wild-type GLP-2 sequence, optionally in combination with further substitutions at position 2 (as mentioned in the introduction) and one or more of positions 3, 5, 7, 10 and 11, and/or a deletion of one or more of amino acids 31 to 33 and/or the addition of a N-terminal or C-terminal stabilizing peptide sequence. The analogues are particularly useful for the prophylaxis or treatment of stomach and bowel-related disorders and for ameliorating side effects of chemotherapy. Also disclosed are methods and kits for selecting a patient from populations suited for treatment with GLP-2 analogues.

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.

The present invention is in the field of viral immunotherapy. The invention provides new pseudocowpox (PCPV) viruses, in particular recombinant PCPV, composition thereof as well as their therapeutic use for preventing or treating diseases, and, notably, proliferative diseases like cancers and restenosis and infectious diseases such as chronic ones. The present invention also provides methods for generating and amplifying such a PCPV and a method for eliciting or stimulating and/or re-orienting an immune response using such a PCPV. More specifically, the invention provides an alternative to the existing poxvirus vectors such as MVA (Modified Virus Ankara) and may be largely used for the therapeutic vaccination.

Methods of preparing papillomavirus nucleic acid transfer vectors, in-disassembled cluding by disassembly/reassembly of papillomavirus L1 and L2 virus-like particles, in a defined, cell-free high-efficiency production protocol. These methods may be used to efficiently encapsidate desired moieties, e.g., toxic or therapeutic nucleic acids such as DNA and RNA, and the resultant pseudovirus particles may be used as in vivo delivery vehicles.

The invention features immunogenic compositions and methods useful for eliciting an immune response. In preferred embodiments, papillomavirus or adenovirus vectors are used to elicit exceptionally potent antibody and T cells responses in disrupted epithelium. The methods are useful in preventing or treating a subject having a disease or an infection. In particular examples, the methods are useful for preventing or treating a viral infection.
