Submitter Supplied Information

Brain gene transfer using viral vectors will likely become a therapeutic option for several disorders. Helper-dependent (HD) canine adenovirus type 2 vectors (CAV-2) are well suited for this goal. Indeed, these vectors are poorly immunogenic, efficiently transduce neurons, are retrogradely transported to afferent structures in the brain, and lead to long-term transgene expression. CAV-2 vectors have been exploited to unravel behavior, cognition, neural networks, axonal transport and therapy for orphan diseases. Here we describe the HD-CAV-2 vector induced transcriptional response of human dopaminergic neurospheres derived from midbrain progenitors. In this 3D model system, brain cell functions and dynamics mimic several aspects the dynamic nature of human brain. With the goal of better understanding and characterizing HD CAV-2 for brain therapy, we analyzed the transcriptomic modulation induced by HD-CAV-2 in this brain model system.
