  • Publication number: 20240025999
    Abstract: Recombinant T cell clonotypes are provided that express T cell receptor alpha and T cell receptor beta polypeptides with specificity for human papillomavirus (HPV) type 16 E6 protein and that amplify in response to a therapeutic vaccine and traffic to ovarian lesional tissue in a patient whose HPV lesions regressed in response to the vaccine. Recombinant T cells expressing appropriate TCR alpha and beta complimentarity determining sequences for HPV 16 E6 binding and treating HPV-cased cancers are provided. Bifunctional proteins having TCR alpha and beta segments that bind to HPV 16 E6 residues 91-115 and a single chain Fv anti-CD3 antibody domain are provided. These bifunctional proteins can direct T cells to HPV-infected cells.

  • Publication number: 20150224186
    Abstract: The present invention is directed to the examination of the pattern of immunodominant T cell epitopes in the E6 protein of Human Papilloma virus and its further characterization in terms of its amino acid sequence and Human Leukocyte Antigen restriction. These epitopes are identified based on their ability to induce specific T cell responses and therefore, are important as sources of antigens for immunotherapies to treat cervical and other cancers. The present invention contemplates identifying a number of similar epitopes restricted by a wide variety of Human Leukocyte Antigen types so that they can be used together to develop preventative or therapeutic vaccines, which can be used for the general human population. The present invention also contemplates using E6 peptides of Human Papilloma virus as a diagnosis method to predict the probability of developing persistent cervical neoplasia in an individual.

  • Patent number: 8252893
    Abstract: The present invention is directed to the examination of the pattern of immunodominant CD8 T cell epitopes in the E6 and E7 protein of Human Papillomavirus (HPV) and its further characterization in terms of its amino acid sequence and HLA restriction. These epitopes are identified based on their ability to induce strong CD8 T cell response and therefore, are important as sources of antigens for dendritic cell immunotherapy to treat cervical cancer. The present invention contemplates identifying a number of similar epitopes restricted by a wide variety of HLA types so that they can be used in concert to develop a preventative vaccine, which can be used for general population.

  • Publication number: 20120045413
    Abstract: The inventors have treated human patients for warts by intralesional injection of Candida antigen to induce a delayed-type hypersensitivity response in the patients. This creates an immune response that recognizes the antigens of the human papilloma virus (HPV) found in and causing the warts. It was found that the patients showed a response to HPV type 57 L1 peptide 380-412 (a peptide consisting of amino acid residues 380-412 of the protein L1) and HPV type 57 protein E4 (E4 10-30). One embodiment of the invention provides a pharmaceutical composition comprising a polypeptide comprising (a) L1 380-412 (SEQ ID NO:3) or a fragment of at least 8 residues of SEQ ID NO:3 or (b) E4 10-30 (SEQ ID NO:4) or a fragment of at least 8 residues of E4 10-30 (SEQ ID NO:4), wherein the composition is immunogenic in humans.

  • Publication number: 20090117140
    Abstract: Provided herein are methods of determining immunodominant T cell epitopes within a protein expressed in an individual and immunotherapy directed towards a protein in an individual using these determined epitopes. The method comprises administering autologous dendritic cells pulsed with a recombinant protein to the individual, establishing T-cell lines therefrom and incubating the T cell lines with representative peptides from the protein to measure and identify those peptides from the protein inducing the T cell response. Also provided are synthetic or recombinant peptides or immunogenic compositions thereof comprising the identified peptide(s) or peptides of similar sequence and a method of preventing or treating a pathophysiological condition.
