Patents by Inventor Eric Von Hofe

Eric Von Hofe has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8748130
    Abstract: The present invention is directed towards compositions comprising Ii-Key/HPV hybrid peptides. The hybrid peptides of the present invention are effective in the generation of CD4+ helper T cell immune responses directed towards the specific HPV epitopes encoded in the hybrid peptide. The inclusion of the Ii-key peptide in the hybrid causes the peptide to have greater immunogenicity as compared to control peptide. The inclusion of Ii-Key/HPV hybrid in a peptide vaccine formulation composing both HPV hybrid and HPV CTL epitope peptide (administered concurrently or sequentially) leads to a greater CTL activity against HPV CTL epitopes. The hybrid peptides of the present invention may be useful, for example, for the immunization of subjects against HPV.

  • Publication number: 20090060889
    Abstract: Provided are compositions and methods involving the inhibition of Ii expression in cells for the purpose of altering antigen presentation pathways. Human Ii-RNAi constructs that effectively inhibit Ii expression in human cancer cells have been generated. The combination of different Ii-RNAi constructs that target different positions of Ii mRNA has a synergistic effect on Ii inhibition. Furthermore, specific promoters for driving Ii-RNAi expression are critical for the activity of Ii-RNAi in different types of cells. Active Ii-RNAi sequences were cloned into plasmids in which Ii-RNAi sequences are driven by either a CMV or an EF-1? promoter. Compositions and methods are disclosed for inhibiting Ii and treating cancer. Provided are siRNAs and expression constructs comprising DNA sequences which encode siRNAs effective to inhibit Ii expression, cells containing such DNA constructs or siRNAs, and methods for use of the same.
