The technology includes USP30 knockout HeLa cells that were generated using CRISPR technology. Parkin and Pink1 are key master genes for triggering the degradation of mitochondria (mitophagy). In contrast, USP30 has been found to be localized in the mitochondria and have a role in antagonizing Parkin function, thereby impeding mitophagy.

This invention relates to methods and algorithms that incorporate information from multiple imaging modalities to identify, estimate the size, and track the time course of brain lesions. Subjects develop brain lesions over the natural course of a disease. Currently, lesions are measured and tracked by a trained neuroradiologist using slice-by-slice inspection, a slow process that is prone to human error and hard to generalize to large observational studies.

This technology includes a cell line that stably expresses YFP-Parkin and mt-mKeima that can be used to study mitochondrial degradation, mitophagy, using flow cytometry (FACS). Compromised mitophagy is implicated in Parkinson disease. The effects of any compounds or genetic alteration on Parkin-mediated mitophagy can be monitored.

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 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 is an improvement on the ability to visualize cortical lesions in neurological diseases that cause focal tissue damage to the cortex, including multiple sclerosis (MS). Two approaches are used. The first approach includes optimization of routinely available diffusion-weighted sequences to maximize resolution and contrast, both of which are required to differentiate small cortical lesions from normal-appearing cortex.

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.

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 relates to the description and therapeutic use of a small molecule that selectively binds to and activates the D3 dopamine receptor. Dopamine receptors (DARs) are members of the G protein-coupled receptor (GPCR) superfamily that play a critical role in cell signaling processes, especially modulating the transfer of information within the nervous system. Members of the DAR subfamilies share high sequence homology, especially the D2 and D3 DARs. Most currently available dopaminergic drugs cross-react with both subtypes to varying degrees.

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.
