Disease Focus: Neurological Disorders
Editing of Parkinson’s disease mutation in patient-derived iPSCs by zinc-finger nucleases
The goal of this proposal is to establish a novel research tool to explore the molecular basis of Parkinson’s disease (PD) – a critical step toward the development of new therapy. To date, a small handful of specific genes and associated mutations have been causally linked to the development of PD. However, how these mutations […]
Development and preclinical testing of new devices for cell transplantation to the brain.
The surgical tools currently available to transplant cells to the human brain are crude and underdeveloped. In current clinical trials, a syringe and needle device has been used to inject living cells into the brain. Because cells do not spread through the brain tissue after implantation, multiple brain penetrations (more than ten separate needle insertions […]
Developing a method for rapid identification of high-quality disease specific hIPSC lines
Elucidating how genetic variation contributes to disease susceptibility and drug response requires human Induced Pluripotent Stem Cell (hIPSC) lines from many human patients. Yet, current methods of hIPSC generation are labor-intensive and expensive. Thus, a cost-effective, non-labor intensive set of methods for hIPSC generation and characterization is essential to bring the translational potential of hIPSC […]
Use of hiPSCs to develop lead compounds for the treatment of genetic diseases
This study will use Ataxia-Telangiectasia (A-T), an early-onset inherited neurodegenerative disease of children, as a model to study the mechanisms leading to cerebellar neurodegeneration and to develop a drug that can slow or halt neurodegeneration. We will start with skin cells that were originally grown from biopsies of patients with A-T who specifically carry “nonsense” […]
Development of small molecule screens for autism using patient-derived iPS cells
Autism Spectrum Disorders (ASDs) are a heritable group of neuro-developmental disorders characterized by language impairments, difficulties in social integrations, and the presence of stereotyped and repetitive behaviors. There are no treatments for ASDs, and very few targets for drug development. Recent evidence suggests that some types of ASDs are caused by defects in calcium signaling […]
Development of a Hydrogel Matrix for Stem Cell Growth and Neural Repair after Stroke
Stroke is the leading cause of adult disability. Most patients survive their initial stroke, but do not recover fully. Because of incomplete recovery, up to 1/3 of stroke patients are taken from independence to a nursing home or assisted living environment, and most are left with some disability in strength or control of the arms […]
Site-specific integration of Lmx1a, FoxA2, & Otx2 to optimize dopaminergic differentiation
The objective of this study is to develop a new, optimized technology to obtain a homogenous population of midbrain dopaminergic (mDA) neurons in a culture dish through neuronal differentiation. Dopaminergic neurons of the midbrain are the main source of dopamine in the mammalian central nervous system. Their loss is associated with one of the most […]
Inhibitory Nerve Cell Precursors: Dosing, Safety and Efficacy
Many neurological disorders are characterized by an imbalance between excitation and inhibition. Our ultimate goal: to develop a cell-based therapy to modulate aberrant brain activity in the treatment of these disorders. Our initial focus is on epilepsy. In 20-30% of these patients, seizures are unresponsive to drugs, requiring invasive surgical resection of brain regions with […]
Neural restricted, FAC-sorted, human neural stem cells to treat traumatic brain injury
Traumatic brain injury (TBI) affects 1.4 million Americans a year; 175,000 in California. When the brain is injured, nerve cells near the site of injury die due to the initial trauma and interruption of blood flow. Secondary damage occurs as neighboring tissue is injured by the inflammatory response to the initial injury, leading to a […]
Repair of Conus Medullaris/Cauda Equina Injury using Human ES Cell-Derived Motor Neurons
Injuries to the spinal cord commonly result from motor vehicle accidents, traumatic falls, diving, surfing, skiing, and snowboarding accidents, other forms of sports injuries, as well as from gunshot injuries in victims of violent crimes. Injuries to the anatomically lowest part of the spinal cord, the lumbosacral portion and its associated nerve roots commonly cause […]
