Abstract: Antibodies against citrullinated protein antigens (ACPA) have shown their relevance for the diagnosis and possibly pathogenesis in arthritis. Described are means and methods for determining antibodies against homocitrulline-containing proteins or carbamylated proteins/peptides (anti-CarP) for the classification of individuals suffering from, or at risk of suffering from, arthritis.
Abstract: Described are methods for removing a proteolytic cleavage site, the HCHWA-D mutation or the amino acids encoded by a trinucleotide repeat expansion from a protein comprising providing a cell that expresses pre-mRNA encoding the protein with an anti-sense oligonucleotide that induces skipping of the exonic sequence that comprises the proteolytic cleavage site, HCHWA-D mutation or trinucleotide repeat expansion, respectively, the method further comprising allowing translation of mRNA produced from the pre-mRNA.
Abstract: The invention provides a polynucleotide comprising a reporter sequence operatively linked to a regulatory element of a gene selected from Bscl2, Srxnl, Cbr3, Ephxl, Nope, Cdknla, Perp, Pltp, Cgrefl, Ltb4r1, Btg2, Gpx2, Ltb4r2, Ddit4l, Fosl1, and Egr1, which regulatory element stimulates expression of the reporter sequence in response to a genotoxic agent or to an oxidative stress-inducing agent. The invention also provides a method of detecting a genotoxic or oxidative stress-inducing agent comprising subjecting a cell containing the polynucleotide of the invention to a test agent; and assessing the expression of the reporter sequence.
Abstract: The invention relates to means and methods for removing a proteolytic cleavage site from a protein comprising providing a cell that expresses pre-mRNA encoding the protein with an anti-sense oligonucleotide that induces skipping of the exonic sequence that encodes the proteolytic cleavage site, the method further comprising allowing translation of mRNA produced from the pre-mRNA.

Abstract: A probe system for electro-stimulation and bio-feedback training of muscles in the pelvic floor region, in particular for pelvic floor physiotherapy and diagnosis, includes a probe having a probe body which is insertable into a vagina or a rectum, and a plurality of electrodes which are positioned at several locations along the length and around the circumference on the outer surface of the probe, the probe system further includes a control unit, operationally coupled to the probe, adapted for receiving EMG signals from each of the electrodes and for processing each of the signals for mapping the response of the muscles in the pelvic floor region.
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.

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.

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.
