This technology involves the generation and use of a mouse model for studying hypogonadism in humans and a cell line to study cellular and molecular properties of gonadotropin-releasing hormone (GnRH) cells. The mouse model expresses the simian virus 40 T antigen driven by the GnRH promoter, resulting in hypogonadism due to an arrest in neuronal migration during development and tumor formation along the migratory pathway. Olfactory bulb tumors in this model animal were dispersed, and GnRH-secreting neuronal cell line (GN/NLT cell line) was established.

This technology includes the creation and use of five human embryonic stem cell (hESC) lines with reporter genes integrated at safe harbor sites. These cell lines can be used to study the biology of stem cell development, including their use as an assay for small molecules.

This invention relates to the synthesis and methods of using a drug, deuterated L-DOPS, to treat deficiencies in the neurotransmitter norepinephrine. This classic neurotransmitter has roles in both the brain and the periphery. In the brain, norepinephrine is thought to play important roles in attention, memory, sleep, pain, movement, distress, and mood. Outside the brain, norepinephrine mediates regulation of the circulation by the sympathetic nervous system by increasing blood pressure.

This technology includes the generation and use of HeLa cell lines that have the TANK-binding kinase 1 (TBK1) gene knocked out solely or in combination with either the genes NDP52 or OPTN. Both NDP52 and OPTN are receptors involved in the degradation of mitochondria, mitophagy. The TBK1 kinase has a role in enhancing the effect of mitophagy on these receptors. Mutations in TBK1 have been shown to be associated with neurodegenerative diseases such as Parkinson, frontotemporal dementia, and amyotrophic lateral sclerosis (ALS).

This technology includes multiple cells with various combinations of autophagy receptors knocked out. The cell lines include knockouts of the OPTN, NDP52, and TAX1BP1 genes that are involved in cargo selective autophagy. These lines may be used to explore how cell biology debris is catabolized, which may be relevant to neurodegenerative diseases like amyotrophic lateral sclerosis (ALS).

This technology includes the combination of an induced pluripotent stem cell (iPSC) line that can inducibly be differentiated into neurons (using an inducible Neurogenin 2, Ngn2, cassette) and enable CRISPR inhibition gene knockdown (via stable expression of dCas9-BFP-KRAB). The combination of these elements in a cell line enables multiple lines of research, including small molecule screens for drug development in neuronal disease models, as well as studying stem cell biology in an iPSC neuronal cell model.

The invention relates to a plasmid that enables gene knowndown (via CRISPRi) in human induced pluripotent stem cells (iPSCs), including derived cell types such as neurons. The plasmid contains homology arms to direct insertion of a cassette into the CLYBL safe-harbor locus in the human genome. The cassette expresses CRISPRi machinery using a CAG promoter. The CRISPRi machinery consists of double degron-tagged dCas9-BFP-KRAB. Addition of the small molecule trimethoprim to cell culture media stabilizes the degron and thereby increases dCas9-BFPKRAB levels, enabling CRISPRi activity.

This invention includes the identification of a new mutation in the collagen type VI (COL6A1) gene, including a method for diagnosing and treating patients with this mutation. Collagen type VI-related dystrophies (COL6-RD) are devastating neuromuscular disorders that manifest with progressive generalized muscle weakness, contractures, and respiratory failure. Currently, no cure exists for COL6-RD.

This technology includes the design and use of several nanobodies that bind to the SARS-CoV2 spike protein receptor binding domain and block spike protein interaction with the angiotensin converting enzyme 2 (ACE2) receptor. Nanobodies are 12-15 kDa single-domain antibody fragments that are more stable and easier to produce in large quantities compared to conventional antibodies. SARS-CoV2 is the virus responsible for the COVID19 pandemic. The SARS-CoV2 spike protein is responsible for viral entry into human cells via interaction with ACE2 on the cell surface.

This technology includes the identification and use of antisense oligonuclecotides (ASOs) complimentary to the 5’UTR of SMN2 (Survival of motor neuron 2) for the treatment of spinal muscular atrophy (SMA). SMA is an autosomal-recessive motor neuron disease caused by the loss of both copies of the SMN1 gene. Copies of the similar gene SMN2 decrease the severity of this disease in a dose-dependent manner. Thus, increasing expression levels of the SMN2 transcript can be used to treat SMA.
