Neutralizing the neurodegenerative effect of ALS-related HERV-K using antibodies

This technology relates to the therapeutic use of antibodies to decrease the potential neurodegenerative effect of the HERV-K retrovirus. Previous work has shown that patients with Amyotrophic Lateral Sclerosis (ALS) can have HERV-K activation. In animal models, activation of HERV-K can lead to neurodegenerative symptoms similar to those exhibited by ALS patients. This neurodegenerative effect is thought to be caused by the release of HERV-K envelope proteins into the extracellular space. Work with monoclonal antibodies in vitro has neutralized the toxicity of this protein.

CRISPR-Mediated Gene Inhibition and Neuronal Differentiation in Human Induced Pluripotent Stem Cell (iPSC) Lines

This invention includes human induced pluripotent stem cell (iPSC) lines that harbor a single copy dCas9-BFP-KRAB at the CLYBL safe harbor locus (mediating CRISPR inhibition of human gene expression) and/or a single copy of dox-inducible NGN2 at the AAVS1 locus (enabling the differentiation of the iPSCs into neurons). The CRISPR-mediated inhibition of human gene expression is maintained into the differentiated neurons, permitting functional studies of targeted genes in neurons.

Synthesis and Use of Positive Allosteric Modulators to Modify D1 Dopamine Receptor Activity

This technology relates to the creation and use of newly identified ligands to the D1 dopamine receptor (D1R). The D1 dopamine receptor is linked to a variety of neuropsychiatric disorders and represents an attractive drug target for the enhancement of cognition in schizophrenia, Alzheimer disease, and other disorders. These ligands are positive allosteric modulators (PAMs) that bind to the dopamine receptor at a site other than where dopamine binds and causes the receptor to have an increased response.

Therapeutic Approaches to Inhibit Replication of ALS-related Endogenous Retroviruses

The technology relates to therapeutic approaches that inhibit and block the replication of the endogenous HERV-K retrovirus. Previous work has shown that patients with Amyotrophic Lateral Sclerosis (ALS) can have HERV-K activation. In animal models, activation of HERV-K can lead to neurodegenerative symptoms similar to those exhibited by ALS patients. Work in these animal models has allowed the identification of the responsible transcription factor (TDP-43) as well as the corresponding positions of the HERV-K promoter binding sites.

Transgenic mice useful for study of gonadotropin-releasing hormone (GnRH) and a GnRH-secreting neuronal cell line (GN cell line)

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.

Synthesis and use of deuterated L-DOPS to treat norepinephrine deficiency

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.

TBK1 and NDP52/OPTN Double Knockout Cell Lines for Studying Mitochondrial Degradation Biology

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).

A Neuronal Induced Pluripotent Stem Cell (iPSC) Line with CRIPSR Inhibition Gene Knockdown

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.

Combinatorial Knockout Cell Line Series Relevant to Cargo Selective Autophagy

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).
