Oral Treatment of Hemophilia

This invention portrays a simple method for treatment of antigen-deficiency diseases by orally administering to a subject a therapeutically effective amount of the deficient antigen, wherein the antigen is not present in a liposome. This method increases hemostasis in a subject having hemophilia A or B, by orally administering to the hemophiliac a therapeutically effective amount of the appropriate clotting factor, sufficient to induce oral tolerance and supply exogenous clotting factor to the subject.

Methods and Materials for Controlling Stem Cell and Cancer Cell Proliferation and Differentiation

This work describes a novel nucleolar mechanism that controls the cell-cycle progression in CNS stem cells and cancer cells. The inventors identified a novel peptide, nucleostemin, found in the nucleoli of CNS stem cells, embryonic stem cells, and several cancer cell lines and preferentially expressed by other stem cell-enriched populations. When stem cells differentiate, nucleostemin expression decreases rapidly prior to cell-cycle exit both in vitro and in vivo. Depletion or overexpression of nucleostemin reduces cell proliferation in CNS stem cells and transformed cells.

Isolation of Hybridomas Producing Monoclonal Antibodies (MAbs) Inhibitory to Human CYP2J2

The National Institutes of Health announces three specific monoclonal antibodies that strongly inhibit and/or immunoblot the human cytochrome P450 2J2 (CYP2J2).

Cytochrome P450s catalyze the NADPH-dependent oxidation of arachidonic acid to various eicosanoids found in several species. The eicosanoids are biosynthesized in numerous tissues including pancreas, intestine, kidney, heart and lung where they are involved in many different biological activities.

Peptides for Treatment of Tumor Necrosis Factor alpha Mediated Inflammatory Disease

Tumor Necrosis Factor alpha (TNF-alpha) is a multifunctional cytokine that mediates inflammation, immune regulation, and cellular proliferation. This cytokine is converted to its active form by TNF-alpha converting enzyme (TACE). Pathological increases in TNF-alpha activity have been associated with a wide variety of inflammatory diseases, including inflammatory bowel disease, rheumatoid arthritis, and cancer. Inhibiting the conversion of TNF-alpha to its active form by inhibiting TACE represents a potential treatment for these diseases.

Vaccines Comprising Sand Fly Salivary Proteins for Control of Leishmania Infection

This invention relates to the use of several peptides from the salivary glands of various sand fly species for the control of leishmania infection. Many of these peptides were shown to be effective in eliciting potent immune responses in animal models and are excellent candidates for the development of vaccines against the disease. A vaccine comprising one of the peptides was used to protect mice challenged with parasites and salivary gland homogenates.

Factors That Bind Intestinal Toxins

This invention discloses and covers polyphenolic compounds that will bind bacterial toxins, methods for the treatment of such infections, specifically Stx-1 toxins from STEC strains of E. coli.

Bacterial infections not only cause disease by their presence but also upon the release of toxins. The common enteric bacteria, E. coli O157:H7 releases such toxins (Stx-1) upon treatment with antibiotics. These toxins, when released into the lumen of the intestinal tract, will cause cellular damage thus increasing the severity of the infection.

HIV-Dependent Expression Vector

This invention provides a DNA construct that can be useful for both diagnostics and AIDS therapeutics. The construct can be incorporated into a retrovirus or into a cell line. This construct mediates the expression of a selected gene in the presence of HIV replication, but is silent in the absence of HIV. The cell line with the incorporated construct can be used as an indicator line for the presence of replication-competent HIV. The virus containing the construct can be used to co-infect a population of HIV-infected cells.

Particles for Imaging Cells

Available for licensing are NIH patent pending contrast particles for use in MRI and flow cytometry to track cells migration in real time. Present cell-tracking studies rely on labeling cells with ultra-small dextran-coated iron particles that are endocytosed. The contrast agent of the present invention uses larger iron oxide particles, approximately 1 µm, situated in a tri-layer structure.

A Mouse Model for Systemic Inflammation in Glucocerebrosidase-Deficient Mice with Minimal Glucosylceramide Storage

Gaucher disease, the most common lysosomal storage disease, is an inherited metabolic disorder in which harmful quantities of the lipid glucocerebroside accumulate in the spleen, liver, lungs, bone marrow and in rare cases in the brain, due to a deficiency of the enzyme glucocerebrosidase (Gba) that catalyses the first step in the biodegradation of glucocerebrosides. Type 1 Gaucher disease is the most common and is distinguished from the other forms of the disease, types 2 and 3, by the lack of neurologic involvement.

A Mouse Model for Type 2 Diabetes

Diabetes affects over 120 million people worldwide (16 million in the US) and is a major health problem with associated health costs estimated at almost $100 billion dollars. Type 2 diabetes affects as many as 10% of the population of the Western World (with 15 million patients in the US alone) and arises from a heterogeneous etiology, with secondary effects from environmental influences. Risk factors for type 2 diabetes include obesity, high blood pressure, high triglycerides and age.
