    The delivery of therapeutic nucleic acids to neurons has the potential to treat neurological disease and spinal cord injury. While select viral vectors have shown promise as gene carriers to neurons, their potential as therapeutic agents is limited by their toxicity and immunogenicity, their broad tropism, and the cost of large-scale formulation. Nonviral vectors are an attractive alternative in that they offer improved safety profiles compared to viruses, are less expensive to produce, and can be targeted to specific neuronal subpopulations. However, most nonviral vectors suffer from significantly lower transfection efficiencies than neurotropic viruses, severely limiting their utility in neuron-targeted delivery applications. To realize the potential of nonviral delivery technology in neurons, vectors must be designed to overcome a series of extra- and intracellular barriers. In this article, we describe the challenges preventing successful nonviral delivery of nucleic acids to neurons and review strategies aimed at overcoming these challenges

    Effektive Poren: Zeolith-Y-Kristalle mit Mikroporen (ca.β€…1β€…nm), kleinen (ca.β€…3β€…nm) und großen Mesoporen (ca.β€…30β€…nm) wurden aus zuvor mit Dampf und SΓ€ure behandeltem Material durch Auslaugen mit Base erhalten. Die Zeolith-Y-Kristalle mit trimodaler PorositΓ€t (siehe elektronentomographische Aufnahme) zeigen beim Hydrocracking eine nahezu ideale SelektivitΓ€t fΓΌr und erhΓΆhte Ausbeuten an Kerosin und Diesel
