  • Patent number: 9289487
    Abstract: Disclosed is an antigen presentation enhancing hybrid polypeptide which includes three elements. The first element is an N-terminal element consisting essentially of 4-16 residues of the mammalian li-Key peptide LRMKLPKPPKPVSKMR (SEQ ID NO: 1) and non-N-terminal deletion modifications thereof that retain antigen presentation enhancing activity. The second element is a chemical structure covalently linking the N-terminal element described above to the MHC Class II-presented epitope described below. The chemical structure is a covalently joined group of atoms which when arranged in a linear fashion forms a flexible chain which extends up to the length of 20 amino acids likewise arranged in a linear fashion, the chemical structure being selected from the group consisting of: i) immunologically neutral chemical structures, ii) a MHC Class I epitope or a portion thereof, and/or iii) an antibody-recognized determinant or a portion thereof.

  • Patent number: 8889143
    Abstract: Provided are methods and compositions for treating cancer in humans, the cancer being characterized by expression of Her-2/neu. The methods involve vaccinating a patient with an Ii-Key/MHC class II hybrid construct and thereby stimulating an immune response to the native Her-2/neu protein. The construct may be in the form of an Ii-Key hybrid peptide or a nucleic acid encoding an Ii-Key hybrid peptide. Methods are described wherein the cancer being treated is breast cancer. Also claimed is a pharmaceutical composition comprising an Ii-Key/MHC class II hybrid construct with and without an adjuvant. The adjuvant can include GM-CSF. The Ii-Key hybrid construct includes the LRMK (SEQ ID NO: 2) residues of Ii-Key protein and an MHC Class II epitope of a protein or portion thereof which is used in the vaccine or a DNA encoding the same hybrid peptide.

  • Publication number: 20080095798
    Abstract: Disclosed is a method for increasing vaccine potency whereby a subject's immune system is first primed with an Ii-Key hybrid peptide construct before the subject subsequently receives a vaccine for a pathogen of interest. The vaccine may be comprised of a protein or portion thereof that is encoded by the genome of the pathogen. The vaccine may also be a DNA vaccine comprised of DNA encoding a protein of the pathogen. The Ii-Key hybrid peptide construct includes the LRMK residues of Ii-Key protein and an MHC Class II epitope of the protein or portion thereof which is used in the vaccine. The Ii-Key construct may be administered in the form of a nucleic acid construct encoding the Ii-Key hybrid peptide. Priming with Ii-Key peptides enhances the immunogenicity of rHA protein and HA and HIV DNA vaccines. Methods are described relating to the use of Ii-Key hybrid constructs in vaccine protocols wherein the pathogen is HIV or Influenza A, including H5N1.

    Abstract: The present invention is directed toward compositions and methods involving the inhibition of Ii expression in cells for the purpose of altering antigen presentation pathways. More specifically, disclosed are compositions and methods which relate to MHC Class II molecule presentation of antigenic epitopes which, under normal circumstances, would not be presented in association with MHC Class II molecules. The invention relates to presentation in cells which normally express MHC Class II molecules, as well as cells which can be induced to express MHC Class II molecules. Embodiments relating to RNA interference of Ii are specifically disclosed.

  • Publication number: 20040243449
    Abstract: A system and method to automatically trigger data extraction from a Dealerships Management System (DMS) and transmitting it to an insurance service provider for automatic, real-time, generation of insurance application. Generally, an indicator is generated that a customer needs automobile insurance at a point-of-sale. The indicator causes the automatic extraction of the customer's information from a database. The extracted customer information is transmitted to a remote computer for automatic insurance fulfillment. Upon receiving the customer's information, the remote computer automatically populates the appropriate fields of an insurance application and transmits the insurance application to the customer. Upon approval of the insurance application by the customer, a confirmation of insurance is sent to the customer.

  • Publication number: 20030054365
    Abstract: Disclosed is a specific regulator of Ii protein expression or immunoregulatory function. Specifically disclosed are several forms of the specific regulator of Ii, including those which function through the formation of a duplex molecule with an RNA molecule encoding mammalian Ii protein to inhibit Ii protein synthesis at the translation level. This class includes copolymers comprised of nucleotide bases which hybridize specifically to the RNA molecule encoding mammalian Ii protein, and also expressible reverse gene constructs. In other aspects, the disclosure relates to MHC class II-positive antigen presenting cells containing a specific regulator of Ii expression. Such cells are useful, for example, in the display of autodeterminant peptides in association with MHC class II proteins. Compositions of the invention find application in methods for treating diseases, for example malignancies and autoimmune disorders, in a patient by enhancing immunological attack on undesired cells.
