Preparation of Benzene-1,4-disulfonamide Derivatives Useful as Therapeutic TRPML1 Receptor Modulators for the Treatment of Lysosomal Dysfunction and Membrane Repair Disorders

This technology includes a series of novel benzene-1,4-disulfonamides that activate TRPML1 receptor. The TRPML1 receptor is a lysosomal Ca2+ channel that has been shown to be involved in controlling lysosome functions, among then the maintenance of the integrity of the plasma membrane and the modulation of autophagosome-lysosome fusion. The improved ability of the receptor to deliver Ca2+ ions to the cytosol had been correlated with its capacity to modulate autophagy and lysosome exocytosis.

Compounds for Niemann Pick C and Other Lysosomal Storage Disorders

This technology includes compounds that improve endoplasmic reticulum-lysosomal trafficking and normalizes the Niemann-Pick type C (NPC) phenotype in assays using NPC1 patient cells, which can be used for the treatment of NPC, other lysosomal storage disorders, and potentially other neurodegenerative disorders. NPC is a rare neurodegenerative lipidosis caused by mutations in NPC1 or NPC2 genes, and characterized by the accumulation of cholesterol and glycolipids in the late endosomes and lysosomes. Currently there is no FDA-approved treatment for this devastating neurodegenerative disease.

Sensor for Real-time Detection of Plasma Metabolites Levels for the Diagnosis and Care of Metabolic Disorders

This technology includes the development of devices capable of real-time evaluation of metabolite levels for the treatment of numerous metabolic disorders, including hyperammonemia and aminoacidopathies. Currently, the monitoring of metabolite levels is done in a hospital setting with specialized mass spectrometry instrumentation. As a consequence, susceptible patients who are undergoing a crisis need to visit the hospital for testing to determine if there is a metabolite disturbance.

Treatment of primary hyperoxalurias with small molecule lactate dehydrogenase inhibitors such as WO2018005807A1

This technology includes the use of novel lactate dehydrogenase (LDH) inhibitors, including WO2018005807A1, for the treatment of primary hyperoxalurias (PHs). PHs are rare autosomal recessive disorders caused by overproduction of oxalate, leading to recurrent calcium oxalate kidney stone disease, and in some cases end-stage renal disease. One potential strategy to treat PHs is to reduce the production of oxalate by diminishing the activity of LDH, the proposed key enzyme responsible for converting glyoxylate to oxalate.

Novel Codon-Optimized MUT Gene Therapeutic for Methylmalonic Acidemia (MMA)

Methylmalonic Acidemia (MMA) is a metabolic disorder characterized by increased acidity in the blood and tissues due to toxic accumulation of protein and fat by-products resulting in seizures, strokes, and chronic kidney failure. A significant portion of MMA cases stem from a deficiency in a key mitochondrial enzyme, methylmalonyl-CoA mutase (MUT), required to break down amino acids and lipids. Currently, there are no treatments for MMA and the disease is managed primarily with dietary restriction of amino acid precursors and liver-kidney transplantation in severe cases.

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.

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).

Tissue Clamp for Repeated Opening and Closure of Incisions/Wounds

Medical clamps currently available are not efficient nor are they sufficiently precise in closure and alignment of the edges of an incision or wound. Many available designs are difficult to use and handle, especially in situations where repeated opening and closure of an incision or wound is required. The functional short-comings of existing clamp designs may result in surgical complications, such as excess loss of fluids and pressure and hemostasis during some procedures.

Gene Therapy for Treatment of CRX-Autosomal Dominant Retinopathies

Mutations in the cone rod homeobox (CRX) transcription factor lead to distinct retinopathy phenotypes, including early-onset vision impairment in dominant Leber congenital amaurosis (LCA). Adeno-Associated virus (AAV) vector-mediated delivery of a CRX cDNA under the control of a CRX promoter region partially restored photoreceptor phenotype and expression of phototransduction genes in an in vitro model of CRX-LCA.

Induced Pluripotent Stem Cells Derived from Patients with CEP290-associated Ciliopathies and Unaffected Family Members

Approximately one-third of non-syndromic retinal dystrophies involve a defect in a ciliary protein. Non-syndromic retinal ciliopathies include retinitis pigmentosa, cone dystrophy, cone-rod dystrophy, macular dystrophy, and Leber-congenital amaurosis (LCA). Many CEP290-LCA patients also exhibit auditory and olfactory defects. Induced pluripotent stem cells (iPS) cells were derived from patients with LCA and unaffected relatives. 
The National Eye Institute (NEI) seeks research collaborations and/or licensees for the use of these iPS cells.
