In this report, we describe the development of a modified adeno-associated virus (AAV) capsid and promoter for transduction of retinal ON-bipolar cells. The bipolar cells, which are post-synaptic to the photoreceptors, are important retinal targets for both basic and preclinical research. In particular, a therapeutic strategy under investigation for(More)
Rod-derived cone viability factor (RdCVF) is a thioredoxin-like protein, which has therapeutic potential for rod-cone dystrophies such as retinitis pigmentosa (RP). Cone loss in rodent models of RP is effectively reduced by RdCVF treatment. In this study, we investigate the physiological role of RdCVF in the retina by analyzing the phenotype of the mouse(More)
In vivo models of hypoxic-ischemic brain injury have shown altered expression of a number of genes that are important in regulating neuronal survival. However, it is not clear as to whether hypoxia alone can alter the expression of genes regulating neuronal survival. We hypothesized that (1) hypoxia alone alters the expression of bcl-2 in neurons, (2) the(More)
The rod-derived cone viability factors, RdCVF and RdCVF2, have potential therapeutical interests for the treatment of inherited photoreceptor degenerations. In the mouse lacking Nxnl2, the gene encoding RdCVF2, the progressive decline of the visual performance of the cones in parallel with their degeneration, arises due to the loss of trophic support from(More)
Mutational heterogeneity in genes causative of dominantly inherited disorders represents a significant barrier for development of therapies directed towards correction of the primary genetic defect. To circumvent the mutational heterogeneity present in rhodopsin- (RHO-) linked autosomal dominant Retinitis Pigmentosa (adRP), a strategy involving suppression(More)
Sub-retinal injection of the common AAV2 pseudotypes frequently results in strong transduction of the retinal pigment epithelium (RPE) as well as the retina itself. This has been of benefit to date in human clinical trials using AAV, where the disease target is in the RPE. However, many mutations predisposing to retinal disease are located in the(More)
