PURPOSE We evaluated adeno-associated virus (AAV)-mediated gene transfer of basic fibroblast growth factor (FGF-2) as a therapy for photoreceptor degeneration in a transgenic rat model of retinitis pigmentosa. METHODS Recombinant adeno-associated virus vector (rAAV) incorporating a constitutive cytomegalovirus (CMV) promoter was used to transfer the bovine FGF-2 gene to photoreceptors. AAV wa...
PURPOSE OF REVIEW Induction treatment of antineutrophil cytoplasmic antibodies (ANCA) associated vasculitis (AAV) is not always successful and nonresponding patients are considered refractory. RECENT FINDINGS Refractory disease should be subdefined to the treatment that was received. Cyclophosphamide refractory AAV occurs in up to 5% of patients. Many more patients develop contraindications t...
A rapid method of ultracentrifugation pelleting of avian adenovirus (AAV) from small volume of chloroform treated infected cell culture fluid or allantoic fluid was adapted for isolation of adenoviral DNA. The viral DNA extracted from semipurified viruses was found to be intact on agarose gel and pure enough (A260/280 = 1.85-1.92) for restriction enzyme analysis. Restriction endonuclease analys...
A variety of gene transfer strategies have been developed to treat inherited, degenerative, and acquired diseases. Among the different vector systems developed so far, recombinant adeno-associated viral (AAV) vectors have shown notable benefits, including prolonged gene expression, transduction of both dividing and nondividing cells, and a lack of pathogenicity caused by wild-type infections. T...
Recombinant adeno-associated viruses (AAVs) are quickly becoming the preferred viral vector for viral gene delivery for the treatment of a wide variety of genetic disorders. However, since their use in a clinical trial targeting hemophilia B patients 10 years ago, immune responses to the AAV capsid appear to have hampered some of the early clinical gene transfer efficacy. Indeed, AAV-based gene...
Delivery of therapeutic genes represents a fascinating possibility to accelerate injury-repairing process in tissues that are otherwise difficult to treat, such as cerebral ischemia. Current studies indicate that gene transfer-induced focal angiogenesis in the brain may provide an important therapeutic strategy. In the present study, we reported the efficacy of induction of angiogenesis with an...
Enterovirus71 (EV71) is now recognized as an emerging neurotropic virus in Asia and one major causative agent of hand-foot-mouth diseases (HFMD). However potential animal models for vaccine development are limited to young mice. In this study, we used an adeno-associated virus (AAV) vector to introduce the human EV71 receptors P-selectin glycoprotein ligand-1 (hPSGL1) or a scavenger receptor cl...
Adeno-associated viruses (AAV) are currently being evaluated in clinical trials for gene therapy of CNS disorders. However, host factors that influence the spread, clearance, and transduction efficiency of AAV vectors in the brain are not well understood. Recent studies have demonstrated that fluid flow mediated by aquaporin-4 (AQP4) channels located on astroglial end feet is essential for exch...
Pulmonary fibrosis (PF) is an uncommon manifestation observed in patients with antineutrophil cytoplasmic antibodies (ANCA)-associated vasculitis (AAV), particularly microscopic polyangiitis (MPA). While patients with PF associated with AAV seem to e Brun, MD, Philip D, avid Saadoun, MD, PhD patients with PF associated with AAV, fulfilling the American College of Rheumatology criteria and/or Ch...
In the presence of complementing adeno-associated virus type 2 (AAV-2) Rep proteins, AAV-2 genomes can be pseudotyped with the AAV-5 capsid to assemble infectious virions. Using this pseudotyping strategy, the involvement of the ubiquitin-proteasome system in AAV-5 and AAV-2 capsid-mediated infections was compared. A recombinant AAV-2 (rAAV-2) proviral luciferase construct was packaged into bot...
