Novel Small Molecule Inhibitors for the Treatment of Huntington’s Disease

This technology is a collection of small molecules screened for their ability to prevent or reduce the cytotoxic effects of the protein, Huntingtin. Huntington's disease is a neurodegenerative disorder due to a dominantly acting expansion of a CAG trinucleotide repeat in exon 1 of the Huntington (HTT) gene resulting in production of the altered (mutant) protein Huntingtin, which has a long chain of polyglutamine (poly Q) attached to the exon 1 encoded protein sequence.

Mouse Model for Cerebral Cavernous Malformation, an Inherited Brain Disorder

Cerebral Cavernous Malformation (CCM) is a brain disease affecting up to 0.5% of the worldwide population. CCM is characterized by grossly dilated vessels prone to leaking and hemorrhage which result in severe headaches, seizures, and strokes. Inherited forms of the disease are due to mutations in one of three loci, CCM1, CCM2, and CCM3. Prior efforts to develop mice with targeted null mutations in Ccm1, Ccm2, or Ccm3 have been unsuccessful, as such mutations result in embryonic death.

Conditionally Immortalized Human Podocyte Cell Lines

Podocytes, cells of the visceral epithelium in the kidneys, are a key component of the glomerular filtration barrier. Podocyte damage and loss contribute to the initiation of glomerular diseases. NIH investigators recently established long-term urinary cell cultures from two patients with focal segmental glomerulosclerosis and two healthy volunteers, via transformation with the thermosensitive SV40 large T antigen (U19tsA58) together with human telomerase (hTERT).

An In-Vitro Cell System Useful For Identification of RORgamma Antagonists

The retinoid-related orphan receptors alpha, beta and gamma (RORalpha, beta and gamma , also referred to as NR1F1, 2 and 3, respectively) comprise a distinct subfamily of nuclear receptors. Study of ROR-deficient mice has implicated RORs in the regulation of a number of biological processes and revealed potential roles for these proteins in several pathologies. NIH investigators have developed an in-vitro system using CHO cells stably expressing a TET-On expression vector regulating RORgamma and a RORE-Luciferase reporter.

Monoclonal Antibodies Against Poliovirus

Early work by Hammond at al. showed gamma globulin to be effective for the prevention of poliomyelitis. Therefore, passive immunotherapy could be another way to treat chronic excretors. Even though prior attempts to use intravenous immunoglobulin (IVIG) and breast milk were unsuccessful, there is reason to think that higher doses of antipoliovirus antibodies could result in complete clearance of poliovirus from chronically infected individuals.

Methods of Treating Giardiasis Using FDA-Approved Compounds

This technology includes a group of at least twenty-nine, diverse, commercially available compounds that are newly identified for activity against Giardia lamblia parasites. At least six of the candidate compounds, Bortezomib, Decitabine, Hydroxocobalamin, Amlexanox, Idarubicin, and Auranofin have preexisting FDA approval for human use for other (non-Giardia) conditions. Another three compounds, Fumagillin, Nitarsone and Carbadox have preexisting approval for veterinary use for non-Giardia conditions.

TL1A Transgenic Mice for the Study of Inflammatory Bowel Disease (IBD) and Allergic-Type Immune Responses

TL1A is a TNF family cytokine that co-stimulates T-cell proliferation and cytokine production through its interactions with the TNF family receptor DR3. TL1A-DR3 interactions have been shown to be important for the development of autoimmune inflammatory diseases, including inflammatory bowel disease (IBD).

Protease Deficient Bacillus anthracis with Improved Recombinant Protein Yield Capabilities

Species of Bacillus, such as Bacillus anthracis, Bacillus cereus, and Bacillus subtilis, are attractive microorganisms for recombinant protein production in view of their fast growth rate, high yield, and ability to secrete produced products directly into the medium. Bacillus anthracis is also attractive in view of its ability to produce anthrax toxin and ability to fold proteins correctly. This application claims a B. anthracis strain in which more than one secreted protease is inactivated by genetic modification.

AAV Mediated CTLA-4 Gene Transfer to Treat Sjogren's Syndrome

Sjögren’s syndrome is an autoimmune disease that affects over 2 million Americans, primarily over the age of 40. One of the major outcomes of Sjögren's syndrome is xerostomia (dry mouth) that is caused by immune system attack on moisture producing salivary glands. Researchers at the National Institute of Dental and Craniofacial Research have developed a therapy that alleviates xerostomia in a murine model of Sjögren's syndrome.

Modulating Autophagy as a Treatment for Lysosomal Storage Diseases

Researchers at NIAMS have developed a technology for treatment of lysosomal storage diseases by inhibition of autophagy. Pompe disease is an example of a genetic lysosomal storage disease caused by a reduction or absence of acid alpha-glucosidase (GAA). Patients with Pompe disease have a lysosomal buildup of glycogen in cardiac and skeletal muscle cells and severe cardiomyopathy and skeletal muscle myopathy. Treatment of Pompe disease by GAA enzyme replacement therapy is quite ineffective for the skeletal muscle myopathy.
