Experimental details Materials: Acryloyl chloride (≥97%) and 2-hydroxyethyl disulfide (90%) were purchased from Sig-ma-Aldrich. The bis(2-acryloyl)oxyethyl disulfide (disulfide-based diacrylate, DSDA, ≥95%) was synthesized according to literature. Styrene (≥95%), ethylene glycol dimethacrylate (EGDMA, 98%), divi-nylbenzene (DVB 80%) was purchased from(More)
Nonviral genetic therapeutic intervention strategies for neurological disorders hold great promise, but a lack of vector efficacy, coupled with vector toxicity, continue to hinder progress. Here we report the application of a newly developed class of polymer, distinctly different from conventional branched polymers, as a transfection agent for the delivery(More)
Aggregation of α-synuclein is believed to play an important role in Parkinson's disease and in other neurodegenerative maladies. Small molecule inhibitors of this process are among the most promising drug candidates for neurodegenerative diseases. Dendrimers have also been studied for anti-fibrillation applications but they can be difficult and expensive to(More)
Reactive astrocytosis and the subsequent glial scar is ubiquitous to injuries of the central nervous system, especially spinal cord injury (SCI) and primarily serves to protect against further damage, but is also a prominent inhibitor of regeneration. Manipulating the glial scar by targeting chondroitin sulfate proteoglycans (CSPGs) has been the focus of(More)
Disease-modifying therapies for Parkinson's disease (PD), with the potential to halt the neurodegenerative process and to stimulate the protection, repair, and regeneration of dopaminergic neurons, remain a vital but unmet clinical need. Targeting the delivery of current and new therapeutics directly to the diseased brain region (in particular the(More)
Despite concerns over toxicity, carbon nanotubes have been extensively investigated for potential applications in nanomedicine because of their small size, unique properties, and ability to carry cargo such as small molecules and nucleic acids. Herein, we show that polymer nanotubes can be synthesized quickly and easily from a homopolymer of ethylene glycol(More)
Parkinson's disease (PD) is a common neurodegenerative disease characterized by a substantial decrease of dopaminergic neurons in the substantia nigra pars compacta. The neurological deterioration during PD can be, in part, attributed to elevated levels of reactive oxygen species (ROS). Radical scavengers have previously been shown to protect dopaminergic(More)
