Abstract: The invention provides nonnaturally occurring dimerizing peptides, and methods for their production. Such peptides are useful to mediate association of linked functional proteins domains. In particular, such peptides are useful for mediating association of complexes of multiple zinc finger proteins thereby affording greater specificity and/or affinity in binding of the zinc finger proteins to proximately spaced target segments.

Abstract: Polynucleotides encoding chimeric proteins, and methods for their production and use are disclosed. The chimeric proteins comprise a flexible linker between two zinc finger DNA-binding domains, wherein the linker contains eight or more amino acids between the second conserved histidine residue of the carboxy-terminal zinc finger of the first domain and the first conserved cysteine residue of the amino-terminal zinc finger of the second domain.

Abstract: Multimeric fusion proteins of an Ig-like domain of Flt-1 are rendered functional by inclusion of a linker moiety. Vectors encoding the fusion proteins and host cells expressing the fusion proteins can be used therapeutically to block neovascularization in individuals with pathological conditions related to neovascularization. Such conditions include age-related macular degeneration, cancer, psoriasis, proliferative diabetic retinopathy, asthma, uveitis, osteoarthritis, and rheumatoid arthritis. The same means of multimerization used for an Iglike domain of Flt-1, i.e., a linker and a multimerization domain, can be used for other polypeptides, including extracellular receptors, antibody variable regions, cytokines, chemokines, and growth factors.

Abstract: Disclosed herein are methods and compositions for targeted cleavage of a genomic sequence, targeted alteration of a genomic sequence, and targeted recombination between a genomic region and an exogenous polynucleotide homologous to the genomic region. The compositions include fusion proteins comprising a cleavage domain (or cleavage half-domain) and an engineered zinc finger domain and polynucleotides encoding same. Methods for targeted cleavage include introduction of such fusion proteins, or polynucleotides encoding same, into a cell. Methods for targeted recombination additionally include introduction of an exogenous polynucleotide homologous to a genomic region into cells comprising the disclosed fusion proteins.

Abstract: We describe a method of producing a modified nucleic acid binding polypeptide, the method comprising the steps of: (a) providing a nucleic acid binding polypeptide comprising a plurality of nucleic acid binding modules; (b) selecting a first binding domain consisting of one or two contiguous nucleic acid binding modules; (c) selecting a second binding domain consisting of one or two contiguous nucleic acid binding modules; and (d) introducing a flexible linker sequence to link the first and second binding domains, the flexible linker sequence comprising five or more amino acid residues. Use of structured linkers, alone or in combination with flexible linkers, is also disclosed.

Abstract: A method of detecting a surrogate marker for active tuberculosis involves obtaining first, second and third samples from a subject suspected of having active tuberculosis, diluting the first sample and exposing part of it to an immobilized mycolic acid antigen in a test vessel and part of it to an immobilized mycolic antigen in a control vessel. The second sample is exposed to mycolic acid antigen-containing liposomes and the third sample is exposed to liposomes not containing mycolic acid antigens. The second sample is added to the test vessel and the third to the control vessel and binding of antibodies to the mycolic acid and antigen in both the test and control vessel is detected. The degree of binding between the test and control vessels is compared and lesser binding in the test vessel is an indicator of the presence of antibodies to the mycolic acid antigen.

Abstract: The present invention provides methods and compositions for producing high titer, wild-type-free preparations of recombinant AAV (“rAAV”) virions. The compositions of the present invention include novel nucleic acids encoding AAV helper functions and AAV helper function vectors. The present invention also includes host cells transfected by the claimed nucleic acids, methods of using the claimed vectors, and rAAV virions produced by such methods.

Abstract: Cloning and expression of genes encoding C. parvum antigenic polypeptides are described as are antibodies that recognize epitopes on these polypeptides. The antigenic polypeptides and antibodies thereto can be used in therapeutic compositions for the prevention and treatment of C. parvum infections, as well as in diagnostic methods for determining the presence of C. parvum infections.

Abstract: The use of recombinant adeno-associated virus (AAV) virions for delivery of DNA molecules to muscle cells and tissue in the treatment of anemia is disclosed. The invention allows for the direct, in vivo injection of recombinant AAV virions into muscle tissue, e.g., by intramuscular injection, as well as for the in vitro transduction of muscle cells which can subsequently be introduced into a subject for treatment. The invention provides for sustained, high-level expression of a delivered nucleotide sequence encoding erythropoietin, and for in vivo secretion thereof from transduced muscle cells such that systemic delivery is achieved.

Abstract: Anti-glucan antibodies have been found to be protective against systemic fungal infection with C. albicans, but the protective efficacy can be inhibited by blocking antibodies. The invention provides an immunogenic composition comprising a glucan and a pharmaceutically acceptable carrier, characterised in that, when administered to a mammalian recipient, the composition elicits protective anti-glucan antibodies but does not elicit antibodies which inhibit the protective efficacy of the anti-glucan antibodies. The glucan may be presented on the surface of a protease-treated microbial cell or may be presented as a protein-glucan conjugate. The glucan may be substituted by a glucan mimotope, a peptidomimetic of a glucan mimotope, or nucleic acid encoding a mimotope. Anti-glucan-antibodies show broad spectrum microbicidal activity. ?-glucans are preferred, particularly those containing one or more ?-1,6 linkages.
