Background: Human Adenovirus species D (HAdV-D) was common human viral pathogen especially in eye infection, consists of several types of which HAdV-D8, -D19 and –D37 were common in eye infection. This study includes detection of HAdV-D types implicated in conjunctivitis based on L2 (Penton protein) gene similarity. Methods: Conjunctival swabs were collected from Keratoconjunctivitis patient...
Pattern recognition receptors (PRRs) are critical to the early detection and innate immune responses to pathogens. In particular, the toll-like receptor (TLR) system and its associated adaptor proteins have essential roles in early host responses to infection. Epidemic keratoconjunctivitis, caused by the human adenovirus, is a severe ocular surface infection associated with corneal inflammation...
Abstract Background and Objective: Respiratory tract infections (RTI) are the most common infectious disorders, worldwide. About 80%-90% of RTI are caused by four viruses such as Adenoviruses, 51 serotypes have been introduced so far. The aim of this survey was to evaluate the frequency of Adenovirus in respiratory infected patients by PCR method in Golestan province, Iran. Material and Me...
Oncolytic adenoviruses represent an innovative approach to cancer therapy. These vectors are typically evaluated in immunodeficient mice with human xenograft tumors. However, in addition to being immunodeficient, this model is limited because normal and cancerous mouse tissues are poorly permissive for human adenovirus replication. This prompted us to search for a model that more accurately ref...
Adenoviruses are used extensively to deliver genes into mammalian cells, particularly where there is a requirement for high-level expression of transgene products in cultured cells, or for use as recombinant viral vaccines or in gene therapy. In spite of their usefulness, the construction of adenoviral vectors (AdV) is a cumbersome and lengthy process that is not readily amenable to the generat...
Adenoviruses are important human pathogens that have been developed as vectors for gene therapies and genetic vaccines. Previous studies indicated that human infections with adenoviruses are self-limiting in immunocompetent hosts with evidence of some persistence in adenoid tissue. We sought to better understand the natural history of adenovirus infections in various non-human primates and disc...
Since targeting of recombinant adenovirus vectors to defined cell types in vivo is a major challenge in gene therapy and vaccinology, we explored the natural diversity in human adenovirus tissue tropism. Hereto, we constructed a library of Ad5 vectors carrying fibers from other human serotypes. From this library, we identified vectors that efficiently infect human cells that are important for d...
PURPOSE To evaluate the efficacy of adenovirus mediated transfer of ornithine delta-aminotransferase (OAT) into human retinal pigment epithelial (RPE) cells. METHODS Adenovirus-mediated gene transfer into primary cultures of human RPE was evaluated by measurement of enzyme activity in whole cell extracts and by Western blot analysis. To assess mitochondrial integrity, succinate dehydrogenase ...
Human adenovirus type 5 enhances the thymidine kinase activity of KB cells but does not induce the enzyme in kinase-deficient HeLa (BU25) cells. Vaccinia induces thymidine kinase activity in both KB and HeLa (BU25) cells. Human adenovirus types 2, 4, 7, and 12 also fail to induce the enzyme in HeLa (BU25) cells. Vaccinia replicates equally well in the presence or absence of HATG (hypoxanthine-a...
