Gene therapy for the central nervous system is poised to become a powerful treatment for numerous neurological disorders. Adeno-associated viral vectors based on serotype 9 (AAV9) have proven themselves to be strong candidates for delivering gene-based therapies throughout the brain and spinal cord when administered intravenously, intrathecally,(More)
BACKGROUND Only recently have data been published attempting to validate a technology and technique suitable for targeted delivery of biological payloads to the human spinal cord. OBJECTIVE To characterize the development and evolution of a spine-stabilized microinjection platform as a vehicle for biologics delivery to the cervical and thoracolumbar spine(More)
The current lack of a validated intraspinal delivery approach precludes translation of promising cell or viral-based therapeutics for treatment of varied spinal cord afflictions. We have developed a stabilized cervical microinjection platform with the intent of precise delivery to intraspinal sites of interest. Nine 30-40 kg female swine underwent(More)
Restraining excitatory neurotransmission within a seizure focus provides a nondestructive treatment strategy for intractable neocortical epilepsy. Clostridial toxin light chain (LC) inhibits synaptic transmission by digesting a critical vesicle-docking protein, synaptobrevin, without directly altering neuronal health. This study tests the treatment efficacy(More)
OBJECTIVE Esophageal perforation is a rare but well-known complication of anterior cervical spine surgery. The authors performed a systematic review of the literature to evaluate symptomatology, direct causes, repair methods, and associated complications of esophageal injury. METHODS A PubMed search that adhered to the Preferred Reporting Items for(More)
OBJECTIVE Apoptosis has been shown to play an important role in motor neuron (MN) degeneration in both neurodegenerative disease and peripheral neuropathy. Bcl-xL, an antiapoptotic protein, is down-regulated in these etiologies [corrected] The carboxyl-terminal domain of the tetanus toxin heavy chain (Hc) has high affinity for axon terminal binding and(More)
OBJECTIVE The first US Food and Drug Administration-approved clinical trial to treat amyotrophic lateral sclerosis (ALS) with neural stem cell-based therapy is in progress. The goal of the current study was to identify and assess the survival of human spinal cord-derived neural stem cells (HSSCs) transplanted into the spinal cord in patients with ALS. (More)
PURPOSE OF REVIEW New minimally invasive techniques are becoming available to treat focal-onset epilepsy. The open surgical treatment of mesial temporal lobe epilepsy (MTLE), although associated with high rates of seizure freedom, is confounded by adverse impacts on neurocognitive function. This review covers new techniques being explored for surgical(More)
PARP-14, a member of the poly ADP-ribose polymerase super family, promotes T helper cell 2 (Th2) differentiation by regulating interleukin-4 (IL-4) and STAT6-dependent transcription. Yet, whether PARP-14 globally impacts gene regulation has not been determined. In this report, using an RNA pol II ChIP-seq approach, we identify genes in Th2 cells that are(More)
