100 results about "Huntington's disease" patented technology

Disclosed herein are methods and compositions for treating or preventing Huntington's Disease.

It is intended to provide methods for suppressing the huntingtin gene expression by using a double-stranded RNA (dsRNA), huntingtin gene expression inhibitors to suppress the huntingtin gene expression, and preventives and/or remedies of Huntington's disease. Targeting against a specific sequence of mRNA at immediately upstream of CAG repeats in HD genes of Huntington's disease, the huntingtin gene expression is suppressed by using a dsRNA homologous to the sequence. In this invention, a short siRNA (short double-stranded RNA) having bp as short as around 21-23 bp can be effectively used as the dsRNA homologous to a specific RNA sequence in a region at immediately upstream of CAG repeats. The dsRNA of this present invention can be used as a huntingtin gene expression inhibitor, or a preventive and/or a remedy of Huntington's disease by administering or introducing into a living body or a living cell in mammals for the prevention and/or treatment of Huntington's disease.

Chimeric proteins are expressed, secreted or released by a bacterium to immunize against or treat a parasite, infectious disease or malignancy. The delivery vector may also be attenuated, non-pathogenic, low pathogenic, or a probiotic bacterium. The chimeric proteins include chimeras of, e.g., phage coat and/or colicin proteins, bacterial toxins and/or enzymes, autotransporter peptides, lytic peptides, multimerization domains, and/or membrane transducing (ferry) peptides. The active portion of the immunogenic chimeric proteins can include antigens against a wide range of parasites and infectious agents, cancers, Alzheimer's and Huntington's diseases, and have enhanced activity when secreted or released by the bacteria, and/or have direct anti-parasite or infectious agent activity. The activity of the secreted proteins is further increased by co-expression of a protease inhibitor that prevents degradation of the effector peptides. Addition of an antibody binding or antibody-degrading protein further prevents the premature elimination of the vector and enhances the immune response.

In particular, the present invention provides methods and assays for identifying agents for use in the prevention and/or treatment of Huntingtons disease. The invention provides polypeptide and nucleic acid TARGETs and siRNA sequences based on these TARGETS.

Huntington's Disease (HD) is an autosomal-dominant inherited progressive neurodegenerative disease from the group of CAG repeat/polyglutamine diseases and is characterized by a triad of psychiatric alterations, dementia and motor dysfunction. On a sub-cellular level, a mutation with extended CAG tri-nucleotide repeats has been identified as the cause of HD. The therapeutic effects of certain substances can be tested on neurotoxically-induced or transgenic animal models with expanded CAG-repeats. In the present invention, transgenic rats were generated and characterized for human HD. Said rat model for human HD and other diseases of the CNS carries 51 CAG repeats under the control of a rat promoter and has a slow progressive neurological phenotype, closely reflecting human HD syndrome. The comparability of the rat model in relation to human HD is characterized by neuropathological, neuroradiological and neurochemical modifications accompanied by typical behavioral symptoms.

The present invention provides a method of detecting an epigenetic abnormality associated with a disease. The method comprises identifying, within a eukaryotic genome, a locus having a hypomethylated sequence specific for the disease and an endogenous multi-copy DNA element. The method can also comprise separate steps of identifying a disease-specific hypomethylated sequence and identifying an endogenous multi-copy DNA element, where the steps may be performed in any order, so long as a locus is identified that has both a disease-specific hypomethylated sequence and an endogenous multi-copy DNA element. The disease-specific hypomethylated sequences detected in accordance with the present invention indicate putative regions of epigenetic dys-regulation and indicate aberrantly regulated nucleic acid sequences that may cause or predispose a patient to disease, such as, but not limited to, Huntingdon s disease, cancers, diabetes, schizophrenia, or bipolar disorder.
