A Phospho-specific antibody to Fc “epsilon” R1 “gamma” as a Diagnostic Tool for Allergic Reactions

This technology includes a mouse monoclonal antibody that recognizes the phosphorylated form of the FceRiy which could be used as a diagnostic tool during allergic reactions. The FcERI is central to the activation of mast cells and basophils and activation of this receptor induces these cells to secrete mediators that cause allergic symptoms. This antibody specifically recognizes the phosphorylated tyrosine 47 (Y 47) of the FceRiy. Phosphorylation of this site Indicates that this receptor is in an active state and thus the cells can secrete allergic mediators.

Use of Regulatory Genetic Variants of IL 1 RN to Guide Therapeutic Decision Making in Systemic Juvenile Idiopathic Arthritis Patients

This technology includes the use of genetic markers to predict the response of patients, particularly children with systemic juvenile idiopathic arthritis (sJiA), to anakinra treatment. Anakinra is a human recombinant IL-1 RA used in treating sJiA, a severe childhood inflammatory disease where early and effective treatment is essential for better long-term outcomes. Through the analysis of 38 children with sJiA treated with anakinra, specific sJiA-associated SNPs (single nucleotide polymorphisms) were identified as predictors of therapeutic failure, with a significant odds ratio of 17.3.

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.

Modulating Autophagy as a Treatment for Lysosomal Storage Diseases

Researchers at NIAMS have developed a technology for treatment of lysosomal storage diseases by inhibition of autophagy. Pompe disease is an example of a genetic lysosomal storage disease caused by a reduction or absence of acid alpha-glucosidase (GAA). Patients with Pompe disease have a lysosomal buildup of glycogen in cardiac and skeletal muscle cells and severe cardiomyopathy and skeletal muscle myopathy. Treatment of Pompe disease by GAA enzyme replacement therapy is quite ineffective for the skeletal muscle myopathy.

DLX3-floxed mice (DLX3f/f) for Use in Drug Development and In Vivo Research Studies for Ectodermal Dysplasia Disorders

This technology includes the creation of DLX3-floxed mice, specifically designed for conditional deletion of the DLX3 gene via Cre-mediated recombination. This innovative approach aims to develop mouse models for studying ectodermal dysplasia disorders. Ectodermal dysplasias are a diverse group of genetic conditions affecting the development of ectodermal structures, including hair, teeth, and bones. The DLX3f/f mice are particularly valuable for modeling specific disorders such as Tricho-dento-osseous syndrome (TDO), Amelogenesis Imperfecta (AI), and Dentinogenesis Imperfecta (DI).

DLX3 Knockout Mice for the Study Mouse Models of Tooth, Hair, and Epidermal Defects

This technology includes K14creDLX3 conditional knockout (cKO) mice which will be used to study ectodermal dysplasia disorders such as Amelogenesis Imperfecta, and to study molecular mechanisms of DLX3 regulation in skin and ectodermal appendages. DLX3 is expressed in the epidermis, hair matrix cells in the hair follicle and in the mesenchymal and epithelial compartment of the tooth during embryonic development. To determine the transcriptional network dependent on DLX3-function, we will generate and analyze an epithelial-specific conditional knockout of DLX3.

Engineered Human Induced Pluripotent Stell Cell (iPSC) Lines for Multiple Therapeutic and Diagnostic Uses

This technology includes ten engineered human induced pluripotent stem cell (iPSC) lines with reported genes inserted into safe harbor sites for use in therapy and diagnostic screening assay development as well as basic stem cell biology research. These cell lines have the potential to differentiate into all cells in the body, and theoretically can proliferate/self-renew indefinitely.

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.

Astrocyte Differentiation of Neural Stem Cells with StemPro Embryonic Stem Cell Serum Free Medium for Research and Potential Therapeutic Use

This technology includes an innovative method for differentiating astrocytes from neural stem cells (NSCs). The process involves using Life Technologies StemPro embryonic stem cell serum-free medium to initially guide NSCs towards a neuronal lineage. Over a period of 28-35 days, as the cells are continually passaged, neurons gradually die off, leading to the proliferation of astrocytes. By the end of this differentiation protocol, approximately 70% of the cells exhibit markers characteristic of mature astrocytes, specifically GFAP.
