Antineutrophil cytoplasmic antibody-associated vasculitis (AAV) presents a variety of manifestations. Two patients with a history of intractable otitis media were diagnosed as having AAV. One was an 87-year-old woman who presented with cough, anorexia, and fever with a one-year and four-month history of otitis media, and the other was a 65-year-old woman with arthritis that appeared after the d...

INTRODUCTION The complement system is crucial for the development of antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). In particular, C5a plays a central role. In this study, plasma and urinary levels of C5a as well as renal C5a receptors (CD88 and C5L2) expression were investigated in patients with AAV. METHODS Twenty-four patients with AAV in the active phase, 19 patie...

The human parvovirus adeno-associated virus (AAV) infects a broad range of cell types, including human, nonhuman primate, canine, murine, and avian. Although little is known about the initial events of virus infection, AAV is currently being developed as a vector for human gene therapy. Using defined mutant CHO cell lines and standard biochemical assays, we demonstrate that heparan sulfate prot...

Gene delivery vectors based on adeno-associated virus (AAV) have significant therapeutic potential, but much room for improvement remains in the areas of vector engineering and production. AAV production requires complementation with either helper virus, such as adenovirus, or plasmids containing helper genes, and helper virus-based approaches have distinct advantages in the use of bioreactors ...

We examined cytoplasmic trafficking and nuclear translocation of adeno-associated virus type 2 (AAV) by using Alexa Fluor 488-conjugated wild-type AAV, A20 monoclonal antibody immunocytochemistry, and subcellular fractionation techniques followed by DNA hybridization. Our results indicated that in the absence of adenovirus (Ad), AAV enters the cell rapidly and escapes from early endosomes with ...

Anti-neutrophil cytoplasmic antibody-associated vasculitis (AAV) is a group of autoimmune diseases that normally affects multiple organs. Recurrent gastrointestinal (GI) bleeding, a critical complication of AAV, remains a challenge. Here, we report a case of AAV complicated by pulmonary hemorrhage, severe recurrent gastrointestinal bleeding, and rapid progressive renal insufficiency that was tr...

SUMMARY The unique life cycle of adeno-associated virus (AAV) and its ability to infect both nondividing and dividing cells with persistent expression have made it an attractive vector. An additional attractive feature of the wild-type virus is the lack of apparent pathogenicity. Gene transfer studies using AAV have shown significant progress at the level of animal models; clinical trials have ...

AAV are a group of systemic immune-mediated diseases with a strong and highly specific association with ANCA. In recent years, there has been increasing evidence that ANCA might play a direct pathogenic role in triggering AAV. Nevertheless, effectors of cell-mediated immunity prevail in the inflammation sites in patients with AAV. Numerous studies found increased markers of T-cell activation in...

Adeno-associated virus (AAV) is a small, non-pathogenic dependovirus that has shown great potential for safe and long-term expression of a genetic payload in the retina. AAV has been used to treat a growing number of animal models of inherited retinal degeneration, though drawbacks-including a limited carrying capacity, slow onset of expression, and a limited ability to transduce some retinal c...

This study tried to evaluate the application of a novel cancer gene therapy using recombinant adeno-associated virus (AAV) carrying the kringle 1 domain of human hepatocyte growth factor (AAV-HGFK1) in combination with recombinant adenovirus carrying p53 gene (Ad-p53). BALB/c and nude mice models of colon cancer were established and the mice were treated with AAV-HGFK1 alone or in combination w...
