  • Patent number: 9650423
    Abstract: Epitopes derived from human papilloma virus and peptides having a size of about 22-45 amino acid residues comprising minimal T cell epitopes are disclosed. Also disclosed are clinically relevant approaches for immunizing subjects against (Myco) bacterially and/or virally infected cells or tumor cells. Peptide sequences of 22-35 amino acid residues in length can induce both peptide-specific CD8+ cytolytic cells and CD4+ T-helper cells. Moreover, vaccination with 22-35 residue long peptides results in a more vigorous CD8+ cytolytic T-cell response than vaccination with peptides of the exact minimal CTL epitope length. The intrinsic capacity of certain minimal CTL epitopes which instead of activating cytolytic effector cells tolerize these cytolytic cells, can be overcome by use of these 22-35 amino acid long peptides.

  • Patent number: 9623103
    Abstract: The invention provides the discovery and characterization of a novel arterivirus protein (nsp2TF), whose expression is dependent on ?2 ribosomal frameshifting at a site located in the nsp2 coding region. The coding region for the unique TF domain of nsp2TF overlaps the part of ORF1a that encodes the transmembrane region of nsp2 in arteriviruses, including PRRSV, LDV and SHFV. Mutations affecting the expression of nsp2TF impair PRRSV replication and result in a smaller plaque phenotype. Provided herein are arteriviruses that display reduced translation of nsp2TF and/or altered translation of one or more downstream products, arteriviruses in which nsp2TF function is reduced and/or absent, and vaccines comprising said arteriviruses. Also provided herein are diagnostic methods, methods for identifying compounds that inhibit ?2 frameshifting, and gene expression tools for eukaryotic systems utilizing ?2 frameshifting.

  • Patent number: 9393219
    Abstract: The metabolization of certain phenols, monophenols or benzenediols into reactive quinone compounds, in particular ortho-quinones and related reactive intermediates, which is brought about by oxidation of monophenols and benzenediols by proteins exhibiting tyrosinase activity, such as human tyrosinase and the related proteins TRP1 and TRP2. The compounds function as haptens that become covalently bound to the tyrosinase enzymes, in particular to histidine moieties, in or near the catalytic site of proteins exhibiting tyrosinase activity, such as tyrosinase, TRP1 and TRP2. An immune response is then to be mounted against these haptenized auto-antigens to treat malignancies.
