The disclosed invention provides materials and methods to treat granulocytopenia (low white cell count in the blood) which is characterized by a reduced number of granulocytes (relative) or an absence of granulocytes (absolute). This condition is commonly associated with cancer chemotherapy, but is seen less frequently in a number of conditions including the use of propylthiouracil, radiotherapy for marrow ablation for bone marrow transplantation, aplastic anemia, systemic lupus erythematosus, AIDS and a variety of other situations.

The invention described and claimed in this patent application is related to the delivery of heterologous nucleic acids or genes to particular target cells. In particular, the application relates to methods of delivering a heterologous nucleic acid or gene of interest to particular target cells using an Adeno-Associated Virus of serotype 5 (AAV5). The particular target cells identified include the alveolar cells of the lung and cerebellar and ependymal cells of the brain.

This invention describes methods and compositions of peptides that inhibit the binding of Plasmodium falciparum (P. falciparum) to erythrocytes. Malarial parasites enter the red blood cell through several erythrocyte receptors, each being specific for a given species of Plasmodia. For P. falciparum, the erythrocyte binding antigen (EBA-175) is the ligand of the plasmodia merozoites that interacts with the receptor glycophorin A on the surface of red blood cells.

This invention relates to materials and methods associated with polymorphic variants in two enzymes involved in folate-dependent and one-carbon metabolic pathways important in pregnancy-related complications and neural tube birth defects: MTHFD1 (5,10-methylenetrahydrofolate dehydrogenase, 5,10-methenyltetrahydrofolate cyclohydrolase, 10-formyltetrahydrofolate synthase) and methylenetetrahydrofolate dehydrogenase (NADP+ dependent) 1-like (MTHFD1L). These enzymes are extremely important in the promotion of DNA synthesis, a process that is critical for normal placental and fetal development.

The inventors have developed methods and reagents for the detection of bone sialoprotein (BSP) in biological samples. The technology relates to the disruption of a serum complex that masks the majority of BSP from established detection systems. Furthermore, there is evidence that there may be a more acidic form of BSP secreted not by normal bone, but only by tumors. Detection of BSP in serum may be a good marker of various bone diseases and a variety of cancers including breast, prostate, lung, and thyroid.

Monoclonal antibodies directed at the proteins of murine leukemia viruses (MuLVs) have some value as immunological reagents, but differ greatly in their applicability. The kit described in this invention uses a monoclonal antibody designated 83A25, which identifies almost all ecotropic, xenotropic, polytropic, and amphotropic MuLVs. It can be used in a wide variety of procedures, including focal immunofluorescence assays on live or fixed monolayers, immunoblotting, immunoprecipitation, immunohistochemical, and flow cytometric procedures.

A synthetic composition that contains the transglutaminase 1 (TGase I) enzyme and a lipid vesicle, which can be used to provide ameliorative therapy for inherited autosomal recessive ichthyoses (ARI). Icthyoses are rare inherited skin disorders that result in extensive scaling of the skin. Because this abnormality can affect heat and fluid transfer through the skin, individuals with this disease may have an increased risk for dehydration and skin infections. Each year, more than 16,000 babies are born with some form of ichthyosis. Ichthyosis affects people of all ages, races and gender.

This application describes a composition and method for treating inflammatory bowel disease or other autoimmune diseases. The composition utilizes a vector which contains a first promoter which controls the expression of a regulatory transcription factor and a second inducible promoter which controls the expression of the gene of interest. The preferred gene of interest encodes an isoform of TGF-beta such as TGF-beta₁ or TGF-beta₃. The isoform of TGF-beta does not have to be hTGF-beta and can be a latent or active isoform of TGF-beta.

The invention provides a method of diagnosing X-linked severe combined immunodeficiency (XSCID) in males or determining whether females are carriers. This method is based upon the presence of either a mutated or truncated IL-2Rgamma gene. The invention also discloses a method of treating XSCID as well as a method for monitoring the therapy.

The complexity of taste discrimination (salty, sour, sweet, umami and bitter) varies between human individuals and populations. Sweet and umami (the taste of glutamate) tastes play a major role in the perception of calorically-rich and essential nutrients and there are well-documented differences in individual perception of sweet and umami flavorings, many of which appear to be genetic in origin.
