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.

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.

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.

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.

This mouse has been generated by targeted gene disruption. The mouse provides a model to investigate the function of the chemokine receptor CX3CR1, which is a proinflammatory receptor for the leukocyte chemoattractant CX3CL1 (aka fractalkine). As an example, the mouse is in use in the study of atherosclerosis. Further, the mouse may serve as a model study the role of the immune system during infection with pathogens as well as other immunologically mediated diseases and responses to tumors.

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.

Bitter taste has evolved in mammals as a central warning signal against ingestion of poisonous or toxic compounds. However, many beneficial compounds are also bitter and taste masking of bitter tasting pharmaceutical compounds is a billion dollar industry. The diversity of compounds that elicit bitter-taste sensations is vast and more than two dozen members of the TAS2R bitter taste receptor gene family have been identified.

Cataract is the most common cause of blindness worldwide, with an estimated 25 million blind and 119 million visually impaired individuals worldwide. Over 20 million adults in the US alone are currently diagnosed with cataracts making this disease a major health concern. The incidence of cataract increases with age and a number of etiologic factors have been proposed in the pathogenesis of age-related cataract in humans including genetic factors, environmental factors and metabolic and biochemical changes in the crystalline lens.

The vanilloid receptor (VR) is a cation channel predominantly expressed on the peripheral processes and perikarya of nociceptive primary afferent neurons. Previous studies have shown that activation of the peripheral receptors by agonists such as capsaicin from hot peppers, or the much more potent resiniferatoxin, produces acute pain sensation which may be followed by desensitization. These inventors discovered that administration of VR agonists in the vicinity of neuronal cell bodies expressing the VR receptor can actually destroy those cells.

Expression of the HIV-1 Vif protein in the absence of other viral factors such a Tat and Rev is extremely inefficient due to the presence of inhibitory sequences on its mRNA. This invention uses codon optimization to remove such inhibitory sequences without altering the amino acid sequence of the protein. The modified vif gene in the resulting pcDNA -hVIF vector is expressed under the control of the CMV promoter. In this, the protein functions as wild type and is more amendable to high-level expression in mammalian cells.
