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 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.

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.

The technology relates to the identification and validation of eight biomarkers for active central nervous system (CNS) intrathecal inflammation. The management of neuroimmunological diseases is severely hindered by an inability to reliably measure intrathecal inflammation. Current laboratory tests, that were developed over 40 years ago, do not capture low to moderate levels of CNS inflammation and provide limited information about its phenotype.

This technology includes the creation and use of a polyclonal antibody for Neuroligin-4, NLGN4, that was created by injecting a peptide surrounding the pT707 phosphorylation site into rabbits and affinity purifying the resulting serum. Neuroligin-4 is a member of the neuroligin family of cell adhesion proteins. This family has been shown to play a role in the maturation and function of the neuronal synapse and has been implicated in patients with autism and intellectual disability.

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 an automated and non-invasive assessment system called Automated Identification of subjects at risks of Multiple Sclerosis (AIMS) to assist clinicians in their diagnostic evaluation. A focus of AIMS is the ‘central vein sign’ (and other radiological findings).

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 design and implementation for 1H-nuclear magnetic resonance imaging (MRI) that allows single transmit hardware to be "transformed" for another nucleus excitation to perform multi-nuclear MR. A radiofrequency (RF) optically controlled switch-mode amplifier prototype is tuned for excitation of two nuclei. The amplifier received the nuclei carrier signals optically through a single fiber.
