Disease Focus: Neurological Disorders
Treatment of Myasthenic Syndrome due to Choline Acetyltransferase Deficiency Using AAV9-mediated Gene Therapy
Research Objective Use of a viral vector to transport a normal gene to children with severe motor and respiratory disabilities caused by an inborn defect of the choline acetyltransferase (ChAT) gene. Impact Treatment of an incurable disease in infants and potential amelioration of symptoms of neuro degenerative diseases with deficient cholinergic system such as Alzheimer […]
C9orf72 repeat expansion-tuned allelic suppression by CRISPRi as an ALS therapy
Research Objective We aim to discover an adeno-associated viral (AAV) CRISPRi gene therapy for amyotrophic lateral sclerosis (ALS) patients with hexanucleotide repeat expansions in the C9orf72 gene. Impact This therapy can be administered intravenously once, have long lasting effects, and is indicated for all ALS patients who carry repeat expansions of varying lengths and toxicity […]
A First-in-Class Treatment for Progressive Multifocal Leukoencephalopathy Via Multimodal Immune System Engineering
Research Objective We propose to discover genome- and epigenome-edited allogeneic T cells engineered to selectively target JCV as a potentially lifesaving treatment for progressive multifocal leukoencephalopathy (PML). Impact If successful, we would revolutionize treatment for PML patients in whom T cell immunity cannot be restored or boosted and unable to wait for adoptive transfer of […]
Excitatory spinal interneurons from human pluripotent stem cells to treat spinal cord injury
Research Objective The primary objective of this research is to test whether excitatory human V2a spinal interneurons engineered from PSCs can repair the damaged spinal cord and restore motor function. Impact Currently no existing therapies are capable of repairing the injured spinal cord. Our therapeutic cell candidate – human ‘V2a’ spinal interneurons – could address […]
Gene Therapy for SLC6A8 Creatine Transporter Disorder
Research Objective The objective is to define a final therapeutic candidate for an effective gene therapy for mutations of the creatine transporter SLC6A8, a major cause of X-linked intellectual disability (ID). Impact This disorder results in severe ID, autistic-like behavior, seizures, & lack or delay of speech with no treatment. Improving brain transduction is essential […]
A Novel Therapy for Sanfilippo B
Research Objective To develop a Stem Cell therapy for Sanfilippo B syndrome. Impact There is no treatment for Sanfilippo syndrome, and other therapeutic approaches have failed in clinics. This proposal will develop a stem cell based therapy for Sanfilippo syndrome. Major Proposed Activities Generation of universal donor Embryonic Stem Cells (ESC H1) using state of […]
A treatment for Rett syndrome using glial-restricted neural progenitor cells
Research Objective We developed a novel glial-restricted neural progenitor cells transplantation strategy as a treatment for Rett syndrome, reverting neuronal alterations caused by genetic mutations. Impact There are no disease-modifying therapies for Rett syndrome. Our therapeutic, if successful, will be a first-in-class treatment for this devastating neurological disorder and potentially others. Major Proposed Activities Characterization […]
Autologous stem cell-derived interneuron cell therapy for spinal cord injury (SCI)
Research Objective Functional restoration following spinal cord injury using defined excitatory and inhibitory spinal interneuron progenitor cell transplantation Impact The development of a stem cell derived progenitor cell therapy with disease modifying potential for spinal cord injury Major Proposed Activities Define and characterize DI4 GABA and V3 Glut spinal interneuron progenitor cells derived from pluripotent […]
Novel antisense therapy to treat genetic forms of neurodevelopmental disease.
Research Objective We propose to discovery and evaluate antisense gene therapy for specific mutations underlying debilitating or life-threatening neurodevelopmental diseases including epilepsy and autism syndromes. Impact The conditions are four specific neurodevelopmental syndromes where mutations are well suited to ASO therapy. The bottlenecks are current lack of cellular evidence for ASOs to impact disease course. […]
Drug Development of Inhibitors of Inflammation Using Human iPSC-Derived Microglia (hiMG)
Research Objective We will screen for modifiers of the response to misfolded αSyn and Aβ, and their cognate antibodies. Development of drugs to combat this inflammation is important in neurodegenerative diseases. Impact Inhibiting the immune response to minimize NLRP3 inflammasome activation may prevent the neurotoxic effect of activated microglia, and attenuate disease progression in neurodegenerative […]
