Fibroblast Cell Lines (with L444P/RecNci1 Genotype) for the Screening of Small Molecules for Gaucher Disease Treatment

This technology includes two human fibroblast cell lines to be used to study the defects in GBA1 gene and protein and to screen small molecules for involvement in Gaucher disease. Glucocerebrosidase (GBA1 or GCase or beta-glucosidase) is a lysosomal enzyme, responsible for breakdown of a fatty material called glucocerebroside (or glucosyl ceramide). Deficiency or malfunction of GBA1 leads to the accumulation of insoluble glucocerebrosides in tissues, which is a major symptom of Gaucher disease.

Identification and Use of a Novel Functionally Selective GHSR1a Ghrelin Receptor Inhibitor, including NCGC00538279, for the Treatment of Food and Chemical Addiction

This technology includes a chemical series, including the NCGC00538279 compound, that selectively activates the GHSR1a G-protein pathway for calcium mobilization while only partially activating the beta-arrestin-2 translocation pathway. The resulting chemical series may be therapeutically valuable for addictive disorders. Activation of the GHSR1a G-protein pathway promotes production and secretion of multiple hormones, including insulin, growth hormone, and IGF1. Activation of the beta-arrestin-2 pathway stimulates dopamine production and may mediate addictive behaviors.

Systemic CRISPR Therapy for the Treatment of Inherited Diseases

This technology includes novel systemic adeno-associated virus (AAV)-mediated CRISPR gene therapy technology. While some diseases (e.g., retinal diseases) can be treated through local gene transfer, many diseases such as Duchenne Muscular Dystrophy (DMD) require systemic therapy. The CRISPR technology has two components, the Cas9 endonuclease, and the gRNA. To explore systemic CRISPR therapy, we co-delivered the AAV.Cas9 and AAV.gRNA vector to mdx mice, a mouse DMD model. Direct delivery to muscle yielded efficient gene correction.

Vascularized Thyroid-on-a-Chip for Personalized Drug Screening and Disease Modeling

This technology includes a micro-engineered “thyroid-on-a-chip” that combines human thyroid organoids with integrated micro-vasculature to replicate the gland’s native blood flow and 3-D architecture, enabling rapid, patient-specific drug screening. By permitting real-time perfusion of nutrients, hormones, and immune cells, the platform yields more physiologically relevant data than conventional static cultures or animal surrogates.

Rabbit Antisera to Various Matrix, Matricellular, and Other Secreted Proteins

The extracellular matrix (ECM) is composed of a group of proteins that regulate many cellular functions, such as cell shape, adhesion, migration, proliferation, and differentiation. Deregulation of ECM protein production or function contributes to many pathological conditions, including asthma, chronic obstructive pulmonary disease, arthrosclerosis, and cancer. Scientists at the NIH have developed antisera against various ECM components such as proteoglycan, sialoprotein, collagen, etc.. These antisera can be used as research tools to study the biology of extracellular matrix molecules.

In-vivo System to Interrogate the Functions of Mucous Membranes and Identify Mucin/Glycan Mimetics and JAK/STAT Inhibitors for the Treatment of Diseases of the Oral Cavity and Digestive Tract

This technology includes a Drosophila mutant strain that can be used as an in vivo model for diseases of the oral cavity and digestive tract (Sjogren's syndrome, colitis, colon cancer, inflammatory bowel disease), where the mucous membrane is disrupted or non-functional. This mutant lacks a mucous membrane and displays epithelial cell damage, uncontrolled cell proliferation and the up-regulation of conserved signaling pathways (JAK/STAT).

CXCR4 Reduction Leads to Enhancement of Engraftment of Hematopoietic Stem Cells

Methods of enhancing engraftment of donor hematopoietic stem cells (HSCs) by reducing expression or activity of CXCR4 in HSCs is described. HSC are the only cells in the bone marrow that are both pluripotent and long lived. Bone marrow transplantation (BMT) using HSC is an increasingly common medical therapy for severe hematologic cancers and primary hematologic immunodeficiencies. However, for significant HSC engraftment to occur there must usually be pre-transplant conditioning with either irradiation or chemotherapy or both.

LRRK2 Inhibitors: Novel Treatment for Intestinal Bowel Disorders

Use of Leucine Rich Repeat Kinase 2 (LRRK2) inhibitors for the treatment of Intestinal Bowel Disorders (IBD) is disclosed. IBD is a broad term that describes conditions with chronic or recurring immune response and inflammation of the gastrointestinal tract. Crohn's disease and ulcerative colitis, two common forms of idiopathic IBD, are chronic, relapsing inflammatory disorders of the gastrointestinal tract.
