Mouse Models of Cryopyrin-Associated Periodic Syndrome (CAPS) for Drug Discovery

This technology includes mouse models that express versions of mouse cryopyrin protein containing mutations associated with human CAPS disease. We engineered mutations associated with three specific CAPS phenotypes (familial cold autoinflammatory syndrome (FCAS); Muckle-Wells syndrome (MWS); and neonatal onset multisystem inflammatory disease (NOMID)) into the mouse cryopyrin gene (called Nlrp3) to examine the roles of IL-1 β and related cytokines, and better characterize inflammasome functions.

SARS-CoV-2 Neutralizing Nanobodies for Therapeutic and Diagnostic Uses

This technology involves the utilization of highly effective nanobodies, specifically camelid antibodies, derived from immunized llamas to neutralize SARS-CoV-2. Additionally, it employs a unique mouse model, called a "nanomouse," that is engineered to express antibody genes from camels, alpacas, and dromedaries. These nanobodies offer significant advantages over traditional human and mouse antibodies due to their smaller size, which allows them to effectively target and bind to specific areas on antigens.

Human TL 1A-transgenic Mouse as a Disease and Therapeutic Model

This technology includes mouse models of TL 1A diseases, such as inflammatory bowel disease and rheumatoid arthritis, to be used as a platform for studying therapeutic agents. The TNF family cytokine TL 1A co-stimulates T-cells through Its receptor and is required for autoimmune pathology driven by diverse T-cell subsets. Blocking TL 1A in mouse models of these diseases is efficacious blocking TL 1A may be useful for therapy of diseases in which TL 1A plays a pathogenic role.

A Neural Stem Line from a Niemann Pick C (NPC) Type 1 Patient for Therapy Development

This technology includes a neural stem cell (NSC) line derived from a Niemann Pick C (NPC) patient, aimed at advancing research and drug development for NPC, an inherited neurodegenerative disorder characterized by the accumulation of cholesterol in neurons. The NSCs, which serve as a crucial intermediate cell type, can be differentiated into any neuronal or glial cell of the brain or spinal cord under appropriate culture conditions. These cells originate from fibroblasts reprogrammed into induced pluripotent stem cells.

Neural Stem Cells from an iPSC Line Ubiquitously Expressing Green Fluorescent Protein for Basic Science Research and Cell Line Tracking

This technology involves neural stem cells (NSCs) derived from pluripotent stem cells (PSCs) that can differentiate into neurons and glia. The key feature of this technology is the CY2 EEF1A1 GFP iPSC line, which includes a green fluorescent protein (GFP) expressed under the EEF1A1 promoter, leading to its ubiquitous expression in cells. This characteristic makes the NSCs and the neural cells differentiated from this line exhibit green fluorescence. Such cells, when transplanted into animal models like mice and rats, can be easily tracked due to their fluorescence.

Conditional Cell Immortalization Plasmid for Basic Science Research

This technology includes a novel plasmid design for cell immortalization. It uniquely combines the conditional activation of human telomerase and c-myc genes through cumate addition, a method distinct from traditional immortalization techniques which commonly use SV40 T-antigen, telomerase, or c-myc. This plasmid also includes a GFP reporter and a puromycin resistance gene, enhancing the efficiency of the immortalization process.

Generation of Safe-harbor Gene Targeting Donor Plasmids

This technology includes two safe harbor gene targeting donors, specifically designed for applications in the study of induced pluripotent stem cells (iPSC). These include the pAAVS1D-CMV.RFP-EF1a.copGFPpuro and pAAVS1-iCLHN donors. A key feature of these donors is their ability to integrate various transgenes into specific loci through homologous recombination, facilitated by sequences homologous to safe harbor loci. When paired with TALENs targeting these loci, these plasmids enable precise and efficient genome engineering in human cells.

Antibodies to TMC1 Protein for Hearing Loss

This technology includes antibodies for TMC1 protein as a treatment for hearing loss. TMC1 is one of the common genes causing hereditary hearing loss. Our laboratory used synthetic peptides corresponding to the TMC1 protein to immunize rabbits. The resulting antisera were shown to bind to TMC1 protein expressed in heterologous expression systems. TMC1 protein is required for the transduction of sound into electrical impulses in inner ear sensory cells.

Protein Nanoparticles for Antigen Display in Vaccines

The technology relates to a protein-based nanoparticle platform that allows presentation of immunogenic molecules such as influenza virus antigens. This protein platform is made up of hepatitis B capsid/core proteins. The core proteins contain immunogenic loop c/e1, where other antigens can be inserted and the chimeric protein retains the ability to form capsid-like particles. The technology describes the insertion of one or more copies of influenza epitopes derived from the globular head or the stem region of hemagglutinin protein into or around the c/e1 loop of the core protein.
