UNLABELLED The clinical utility of the adeno-associated virus (AAV) gene delivery system has been validated by the regulatory approval of an AAV serotype 1 (AAV1) vector for the treatment of lipoprotein lipase deficiency. However, neutralization from preexisting antibodies is detrimental to AAV transduction efficiency. Hence, mapping of AAV antigenic sites and engineering of neutralization-esca...
INTRODUCTION: For delivery of MRI reporter genes (e.g. ferritin) to the rodent brain, lentiviral (LV) and adeno-associated viral (AAV) vectors are the preferred viral vector systems when aiming for stable, long-term labelling and in vivo visualization of cells. However, their potential limitations for MRI like the generation of unspecific contrast by the vector injection and host response are o...
Recombinant adeno-associated viral (AAV) vectors have rapidly advanced to the forefront of gene therapy in the past decade. The exponential progress of AAV-based vectors has been made possible by the isolation of several naturally occurring AAV serotypes and over 100 AAV variants from different animal species. These isolates are ideally suited to development into human gene therapy vectors due ...
We have investigated the infectious entry pathway of adeno-associated virus (AAV) and recombinant AAV vectors by assessing AAV-mediated gene transfer and by covalently conjugating fluorophores to AAV and monitoring entry by fluorescence microscopy. We examined AAV entry in HeLa cells and in HeLa cell lines which inducibly expressed a dominant interfering mutant of dynamin. The data demonstrate ...
Vector capsid dose-dependent inflammation of transduced liver has limited the ability of adeno-associated virus (AAV) factor IX (FIX) gene therapy vectors to reliably convert severe to mild hemophilia B in human clinical trials. These trials also identified the need to understand AAV neutralizing antibodies and empty AAV capsids regarding their impact on clinical success. To address these safet...
There is increasing interest in adeno-associated virus (AAV) vectors for a wide variety of gene therapy applications. AAV is a nonpathogenic human parvovirus that can mediate long-term transduction of a number of cell types without provoking a significant immune response. These properties make AAV especially attractive for use in gene therapy of rheumatoid arthritis (RA), a chronic inflammatory...
The engineering of novel properties and functions into viral vectors for improved gene delivery remains a barrier to the development of efficient, customized gene delivery vehicles. Rational methods for designing improved viral vectors are often experimentally challenging and laborious, particularly when knowledge of viral structure-function relationships is limited. As an alternative, high-thr...
Leber congenital amaurosis (LCA) is a molecularly heterogeneous disease group that leads to blindness. LCA caused by RPE65 mutations has been studied in animal models and vision has been restored by subretinal delivery of AAV-RPE65 vector. Human ocular gene transfer trials are being considered. Our safety studies of subretinal AAV-2/2.RPE65 in RPE65-mutant dogs showed evidence of modest photore...
The display of copulatory behaviors usually requires the presence of a mate and is, therefore, preceded by a search for and approach to a potential partner. The intensity of approach behaviors is determined by a process labeled sexual incentive motivation. Although it is known that female sexual motivation depends on estrogens, their site of action within the brain is unknown. In the present ex...
