objective(s) recombinant adenoviruses are currently used for a variety of purposes, including in vitro gene transfer, in vivo vaccination, and gene therapy. ability to infect many cell types, high efficiency in gene transfer, entering both dividing and non dividing cells, and growing to high titers make this virus a good choice for using in various experiments. in the present experiment, a reco...

Human adenovirus mostly causes self-limiting diseases but may also induce serious complications in healthy as well as immunocompromised patients. We report a case of a 40-year-old homosexual man with chronic untreated human immunodeficiency virus infection, presenting with dysphagia because of an ulcerative esophagitis caused by human adenovirus. Adenovirus infection as a cause of esophagitis h...

Following joint replication of monkey SA7 adenovirus (C8 strain) and human adenovirus type 2 in green monkey kidney tissue culture, a virus possessing the properties of a hybrid was obtained. It was designated Ad2C8. Ad2C8 preparations contained two types of viral particles: human adenovirus type 2, and hybrid particles. The hybrid virions multiplied in green monkey kidney cells in the presence...

Since the International Health Regulations National Focal Point for United Kingdom alerted WHO of ten cases acute severe hepatitis unknown etiology in children on April 5, 2022, relevant have been reported worldwide. These patients had (negative viruses A–E) and elevated aminotransferase (AST) or alanine aminase (ALT) exceeding 500 U/L. Furthermore, respiratory syndrome coronavirus type 2 (SARS...

Delivery of genes via receptor-mediated endocytosis is severely limited by the poor exit of endocytosed DNA from the endosome. A large enhancement in delivery efficiency has been obtained by including human adenovirus particles in the delivery system. This enhancement is probably a function of the natural adenovirus entry mechanism, which must include passage through or disruption of the endoso...

We here describe a convenient system for the production of recombinant adenovirus vectors and its use for the construction of a representative adenovirus-based cDNA expression library. The system is based on direct site-specific insertion of transgene cassettes into a replicating donor virus. The transgene is inserted into a donor plasmid containing the viral 5' inverted terminal repeat, the co...

We recently demonstrated that lactoferrin, an antimicrobial glycoprotein, can inhibit adenovirus infection by competing for common glycosaminoglycan receptors. This study further characterizes the antiadenovirus activity of the protein, thus demonstrating that lactoferrin neutralizes infection by binding to adenovirus particles and that its targets are viral III and IIIa structural polypeptides.

Adenovirus vectors are widely used in gene therapy clinical trials, and preclinical studies with these vectors are often conducted in mice. It is therefore critical to understand whether mouse studies adequately predict the behavior of adenovirus vectors in humans. The most commonly-used adenovirus vectors are derived from adenovirus serotype 5 (Ad5). The Ad5 hexon protein can bind coagulation ...

Antivector immunity may limit the immunogenicity of adenovirus vector vaccines. We tested sera from individuals immunized with adenovirus type 4 and 7 (Ad4 and Ad7, respectively) vaccine or naturally infected with Ad4 for their ability to neutralize a panel of E1-deleted human and chimpanzee adenoviruses (ChAd). Small statistically significant increases in titers to ChAd63, ChAd3, human Ad35, a...
