background and aims: human adenoviruses can cause a diversity of clinical diseases, but there is no antiviral therapy formally approved by adenovirus infections. thus, antiviral agents derived from medicinal plants which are effective against adenoviruses infections are urgently required. therefore, this research was aimed to evaluate in vitro antiadenovirus activity of pomegranate (punica gran...

Abstract We engineered a novel adenovirus with modified capsid for use as an integrated anticancer gene therapy and to circumvent pre-existing immunity. The adenovirus, SynBAd, when administered intravenously, induced antigen-specific CD8 T cell immunity in the liver of mice (C57BL/6) splenic population effector memory cells at levels equivalent those by human Adenovirus serotype 5 (Ad5). Altho...

We develop candidate HIV-1 vaccines, of which two components, ChAdOx1.tHIVconsv1 (C1) and ChAdOx1.HIVconsv62 (C62), are delivered by the simian adenovirus-derived vaccine vector ChAdOx1. Aberrant adenovirus RNA splicing involving transgene(s) coding for SARS-CoV-2 spike was suggested as an aetiology rare adverse events temporarily associated with initial deployment adenovirus-vectored vaccines ...

A central quest in gene therapy and vaccination is to achieve effective long-lasting expression at minimal dosage. Adenovirus vectors are widely used therapeutics safely deliver genes into many cell types. Adenoviruses evolved use elaborate trafficking particle deconstruction processes, efficient progeny formation. Here, we discuss recent insights how human adenoviruses their double-stranded DN...

The susceptibility of adenovirus to the inhibitory effect of human interferons in vitro was investigated. We tested recombinant human interferons-c~2, -/~1 and -7 against adenovirus serotypes 1 and 5 (group C), 3 and 7a (group B), and a wild strain isolated from an acutely ill child who later died. Pretreatment of WISH cells with interferon-? for 24 h induced a dose-dependent inhibition of mult...

Chlamydophila psittaci is found worldwide, but is particularly common among psittacine birds in tropical and subtropical regions. While investigating a human psittacosis outbreak that was associated with avian chlamydiosis in Hong Kong, we identified a novel adenovirus in epidemiologically linked Mealy Parrots, which was not present in healthy birds unrelated to the outbreak or in other animals...

UNLABELLED The E4-ORF1 gene of human adenoviruses encodes a 14-kDa protein that promotes viral replication as well as cellular metabolic reprogramming, survival, and transformation by constitutively activating cellular phosphatidylinositol 3-kinase (PI3K). We recently reported that the E4-ORF1 protein from subgroup D human adenovirus type 9 upregulates and oncogenically activates PI3K by a nove...

Human and chimpanzee adenovirus vectors are being developed to circumvent preexisting antibodies against common adenovirus vectors such as Ad5. However, baseline immunity to these vectors still exists in human populations. Traditional cloning of new adenovirus vaccine vectors is a long and cumbersome process that takes 2 months or more and that requires rare unique restriction enzyme sites. Her...
