Adenovirus-based vectors are promising tools for genetic vaccination. However, several obstacles have to be overcome prior to a routine clinical application of adenovirus-based vectors as efficacious vectored vaccines. The linear trisaccharide epitope αGal (alpha-Gal) with the carbohydrate sequence galactose-α-1,3-galactosyl-β-1,4-N-acetylglucosamine has been described as a potent adjuvant for ...

We investigated expression of TGF-beta 1/Smad3 after balloon injury in rat carotid arteries as well as the effects of blocking the TGF-beta 1/smad3 signaling pathway on carotid intimal hyperplasia. Rats were randomly divided into control group (C group) and injury group (S group). The latter were randomly divided into intervention group (antisense Smad3 adenovirus vector transfection after ball...

The present study was conducted to determine whether the activation of TRESK in the dorsal root ganglion (DRG) by the TRESK gene recombinant adenovirus vector inhibits the capsaicin-evoked substance P (SP) release using a radioimmunoassay. TRESK is an outwardly rectifying K+ current channel that contributes to the resting potential and is the most...

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...

Recombinant adenovirus vectors have been used to transfer genes to the lungs in animal models, but the extent and duration of primary transgene expression and the ability to achieve expression after repeated vector administration have been limited by the development of antigen-specific immunity to the vector and, in some cases, to vector-transduced foreign proteins. To determine if focused modu...

The prevalence of Adenovirus was determined among children with gastroenteritis/ diarrhea in Warri, Southern, Nigeria. Adenovirus was detected using a lateral flow immunochromatographic test kit (Gastro Vir-Strip, Coris Bioconcept, Belgium). The prevalence of Adenovirus was 11 (14.7%) and there were no association with age and gender of subjects. There is need for routine screening of Adenoviru...

BACKGROUND Adenovirus-mediated gene therapy has been used for squamous cell carcinoma of the head and neck (SCCHN), but the in vivo efficacy has been limited by a lack of tissue specificity and low infection efficiency. We are interested in improving cancer gene therapy strategies using targeted adenovirus vectors. OBJECTIVE To determine if the infection efficiency of adenovirus-mediated gene...

When canine adenovirus type 2 (CAdV-2, or also commonly referred to as CAV-2) vectors are injected into the brain parenchyma they preferentially transduce neurons, are capable of efficient axonal transport to afferent regions, and allow transgene expression for at last >1 yr. Yet, translating these data into a user-friendly vector platform has been limited because CAV-2 vector generation is cha...

Helper-dependent adenoviruses show great promise as gene delivery vectors. However, because they do not integrate into the host chromosome, transgene expression cannot be maintained indefinitely. To overcome these limitations, we have inserted an L1 retrotransposon/transgene element into a helper-dependent adenovirus to create a novel chimeric gene delivery vector. Efficient adenovirus-mediated...
