The present invention relates to methods and systems for increasing the affinity of a T cell receptor (TCR) to its ligand by subjecting the TCR gene to somatic hypermutation. The present invention further relates to use of affinity maturated TCRs to create T cells reactive against a selected antigen.

Provided herein are biologically active single chain relaxin peptides. In particular the present invention relates to single chain relaxin peptides comprising a B chain derived from relaxin-2, the peptide being truncated by one or more amino acid residues at the N-terminus with respect to the sequence of the B chain of native relaxin-2. Typically the single chain relaxin peptides selectively bind to the RXFP1 receptor.

Methods for the production of synthetic spider silk-like proteins in corn endosperm, plant leaf or plant shoot tissue are provided. The present invention provides further methods for the identification of synthetic spider silk-like proteins in corn endosperm, plant leaf or plant shoot tissue.

The invention relates to identification and characterization of recombinant DNA and polypeptides for specific Bt toxin receptors. In particular, the Bt toxin receptors of the invention include those derived from the Lepidopteran super family including the species Trichoplusiani ni, Pseudoplusia includens, Helicoverpa zea, and Spodoptera frugiperda. The receptors of the invention further include those derived from the Coleopteran super family and particularly from the species Diabrotica virgifera virgifera. The recombinant DNA and polypeptides so provided are useful in the identification and design of novel Bt toxin receptor ligands including novel or improved insecticidal toxins for use in a variety of agricultural applications. Materials and methods for identifying novel toxins are also disclosed herein. The invention also provides methods for selecting toxins to combine to control insect populations by manipulating Bt toxin receptor.

There is described a vector for treating a ciliopathy such as Bardet-Biedl syndrome, wherein the vector comprises a promoter operably linked to a ciliopathy gene, wherein the vector can provide transduction of the ciliopathy gene into multiple organs, wherein the promoter is a ubiquitous promoter which can provide expression of the ciliopathy gene in the transduced organs, and wherein the ciliopathy gene encodes a functional protein corresponding to the protein that is mutated in the ciliopathy. Also described is the use of the above vector in a method of treating a ciliopathy, the method comprising administering a therapeutically effective amount of the vector to a patient suffering from a ciliopathy.

The present invention relates to Adeno-associated virus type 9 methods and materials useful for intrathecal delivery of polynucleotides. Use of the methods and materials is indicated, for example, for treatment of lower motor neuron diseases such as SMA and ALS as well as Pompe disease and lysosomal storage disorders. It is disclosed that administration of a non-ionic, low-os-molar contrast agent, together with a rAA9 vector for the expression of Survival Motor Neuron protein, improves the survival of SMN mutant mice as compared to the administration of the expression vector alone.

Described is a unique class of antiviral molecule that can be applied to control and eliminate HIV infection in patients using myeloablation therapies and replenishment with transformed bone marrow stem cells programmed to express the antiviral molecule. These anti-viral molecules target the HIV genome in a highly conserved domain, and when expressed in cells prior to infection will cause the cell to die upon infection with HIV. Cell death insures no proliferation of new virus. Reconstituting the immune system with cells expressing these antivirals prevents re-establishment of HIV infection from reservoirs in the re-established lymphocyte and macrophage populations. Over time, reservoirs will be depleted entirely, effectively eliminating the virus. In effect, this new type of antiviral can be used to cure HIV infections.

The invention relates to novel designer osteogenic proteins having altered affinity for a cognate receptor, nucleic acids encoding the same, and methods of use therefor. More preferably, the novel designer osteogenic proteins are designer BMPs and have altered affinity for a cognate BMP receptor. The designer BMPs demonstrate altered biological characteristics and provide potential useful novel therapeutics.

The present invention provides a method of screening a subject for mutations in the CC2D2A gene that are associated with Joubert syndrome, an autosomal recessive form of mental retardation. The present invention also provides proteins that are associated with Joubert syndrome including proteins that includes an amino acid sequence that terminates in DHEGGSGMES (SEQ ID NO: 1). Also provided are nucleotide sequences encoding such proteins and methods of screening subjects to identify nucleotide sequences or proteins associated with Joubert syndrome.

Novel anti-cancer agents, including, but not limited to, antibodies and immunoconjugates, that bind to human folate receptor 1 are provided. Methods of using the agents, antibodies, or immunoconjugates, such as methods of inhibiting tumor growth are further provided.
