Progress towards developing gene therapy for Gaucher disease has been hindered by the lack of an animal model. Here we describe a mouse model of Gaucher disease which has a chemically induced deficiency of glucocerebrosidase and that accumulates elevated levels of glucosylceramide (GL-1) in the lysosomes of Kupffer cells. Administration of(More)
Target cells infected with adenovirus (Ad) vectors containing intact E3 and E4 regions were found to be relatively resistant to lysis by Ad-specific cytotoxic T lymphocytes. Elements from both the E3 and the E4 regions were required for this effect, leading to the identification of a previously undescribed role for E4 gene products in resistance to(More)
AAV2-sFLT01 is a vector that expresses a modified soluble Flt1 receptor designed to neutralize the proangiogenic activities of vascular endothelial growth factor (VEGF) for treatment of age-related macular degeneration (AMD) via an intravitreal injection. Owing to minimal data available for the intravitreal route of administration for adeno-associated virus(More)
High efficiency gene transfer and gene expression in hepatocytes in vivo can be achieved using recombinant adenoviral vectors. However, the persistence of gene expression in different experimental animal models has been variable. To determine if similar differences could be observed in a single species, persistence of gene expression was studied in inbred(More)
OBJECTIVE Antilymphocyte serum can reverse overt type 1 diabetes in NOD mice; yet, the therapeutic parameters and immunological mechanisms underlying the ability for this agent to modulate autoimmune responses against beta-cells are unclear, forming the rationale for this investigation. RESEARCH DESIGN AND METHODS A form of antilymphocyte serum, rabbit(More)
Inhibition of vascular endothelial growth factor (VEGF) for the management of the pathological ocular neovascularization associated with diseases such as neovascular age-related macular degeneration is a proven paradigm; however, monthly intravitreal injections are required for optimal treatment. We have previously shown that a novel, secreted anti-VEGF(More)
To test the effects of adeno-associated virus encoding sFLT01 (AAV5.sFLT01) on the retinal lesions in Ccl2(-/-)/Cx3cr1(-/-) mice, a model for age-related macular degeneration (AMD), AAV5.sFLT01 was injected into the subretinal space of the right eyes and the left eyes served as controls. Histology found no retinal toxicity due to the treatment after 3(More)
Vascular endothelial growth factor (VEGF) is important in pathological neovascularization, which is a key component of diseases such as the wet form of age-related macular degeneration, proliferative diabetic retinopathy and cancer. One of the most potent naturally occurring VEGF binders is VEGF receptor Flt-1. We have generated two novel chimeric(More)
OBJECTIVE This study aimed to examine the effects of adenovirus-mediated expression of p35, a baculovirus gene, on apoptosis induced by hypoxia/reoxygenation (H/R) in cardiomyocytes. METHODS Neonatal rat cardiomyocytes were infected with recombinant adenoviral vectors expressing p35 (Ad2/CMVp35) or no transgene (Ad2/CMVEV) and were then subjected to H/R.(More)
Adenovirus-mediated gene transfer of Fas ligand (FasL) inhibits neointimal formation in balloon-injured rat carotid arteries. Vascular smooth muscle (VSM) cells coexpressing murine FasL and p35, a baculovirus gene that inhibits caspase activity, are not susceptible to FasL-mediated apoptosis in vitro but are capable of inducing apoptosis of VSM cells that(More)
