Characterization of the nucleic acid binding region
of adenovirus DNA binding protein by partial proteolysis and photochemical cross-linking
Isolation and analysis
of adenovirus type 5 mutants containing deletions in the gene encoding the DNA - binding protein
Barroso spent his first year at GSK's Biopharmaceuticals Centre of Excellence for Drug Discovery near London looking at the use
of adenoviruses in gene - transfer therapy.
Such antibodies are expected to reduce the efficacy of vaccines based on common human
serotypes of adenovirus in a human target population.
Review of «Intrastriatal
Transplantation of Adenovirus - Generated Induced Pluripotent Stem Cells for Treating Neuropathological and Functional Deficits in a Rodent Model of Huntington's Disease» from Stem Cell Translational Medicine by Stuart P. Atkinson.
Special
strains of the adenovirus, the researchers say, have been altered to deploy anticancer genes within tumors, killing cancer cells while leaving healthy ones unscathed.
Now, a new report confirms that the Davis outbreak was the first known
case of an adenovirus jumping from monkeys to humans.
We used the Virochip, a microarray designed to detect all viruses, to identify a new
species of adenovirus (TMAdV, or titi monkey adenovirus) that caused a deadly outbreak in a colony of New World titi monkeys at the California National Primate Research Center (CNPRC), and also infected a human researcher.
In addition, phylogenetic
analyses of adenoviruses from greater apes reveal that they fall precisely into «human» adenoviral species B, C, and E [7].
We initially used consensus primers derived from a highly conserved region of the hexon gene to confirm the Virochip
finding of an adenovirus by PCR [25].
The numerous
advantages of adenoviruses will likely help to tackle one of the greatest problems of cancer medicine: The development of resistances against drugs.
Genetic material is found in the
core of each adenovirus (shown in green) and is surrounded by a protein coat (the red part).
«There is no question that the
efficiency of the adenovirus is much better,» says Williamson, «but there is also no question that everyone would rather get away from (using a) virus strategy if they could.»
To the team's surprise, a single
shot of the adenovirus proved to be enough: after 28 days, eight monkeys survived doses of the virus that killed two unprotected animals.
Merck has initiated a proof - of - concept phase IIb clinical trial to study the
effectiveness of its adenovirus - based vaccine, along with subjects» resistance to infection by the relatively common adenovirus — a potential drawback to the vaccine.
The paper describes two new studies in which investigators evaluated the protective
efficacy of an adenovirus serotype 26 (Ad26) vectored vaccine boosted with a purified envelope protein.
Therefore, Jensen - Jarolim and her team used
parts of adenoviruses, so - called adeno - associated viral particles (AAV particles) as carriers.
When you get the sniffles, your immune system detects the
invasion of an adenovirus or other cold - causing pathogen and counterattacks.
Neither the lab worker nor her family members sought medical attention, and all recovered within 4 weeks, after which it was too late for researchers to swab for
traces of the adenoviruses directly.
Entry of adenoviruses into cells involves an initial attachment of the fiber knob to the cell receptor, followed by internalization via a secondary interaction of the penton base with αv integrins [34], [35].
In nonhuman primates, most epidemiologic
studies of adenoviruses have focused on their identification in fecal samples from asymptomatic animals [6], [7], [8].
To confirm the presence of virus in diseased tissues, we examined lung tissue from affected monkeys by transmission electron microscopy, revealing abundant icosahedral particles
characteristic of adenovirus filling the alveoli (Fig. 1D - 4).
While there, I developed a
class of adenovirus vectors known as «gutted» or helper - dependent Ad.
Scientists have uncovered variations in the surface
structures of adenovirus species that may help us develop better gene delivery tools
Similar regulation of the
synthesis of adenovirus fiber and of simian virus 40 - specific proteins encoded by the helper - defective Ad2 + SV40 hybrid viruses Ad2 + ND5 and Ad2 + ND4del
Proteins containing only half of the coding information of early region
1b of adenovirus are functional in human cells transformed with the herpes simplex virus type 1 thymidine kinase gene and adenovirus type 2 DNA
Recently, inactivated
forms of the adenovirus have been used as vaccine - delivery vehicles, due to their well - known structure, which makes them easier for scientists to modify.
Independent, spontaneous
mutants of adenovirus type 2 - simian virus 40 hybrid Ad2 + ND3 that grow efficiently in monkey cells possess indentical mutations in the adenovirus type 2 DNA - binding protein gene
As a specific disease, Infectious Canine Hepatitis (ICH) is a viral infection caused by a
member of the Adenovirus family.
Dr. Dodds believes that with the
appearance of adenovirus 1 in the Maritimes, if you live in or visit the New England area and your dog could be exposed to potentially infected wildlife, you can add CAV - 2 vaccines — two doses for puppies, and then re-vaccinate adult dogs as needed based on hepatitis titers.

A possible problem facing a human vaccine is that some people already have an immune response to some
strains of adenoviruses, which would reduce the body's response to the vaccine strain.
Now, I've never even seen a
case of adenovirus in my practice, so I asked Dr. Dodds to help us understand what's going on.
To confirm the Virochip
finding of an adenovirus, we used consensus primers to amplify a 301 bp fragment from the hexon gene by PCR [25].
Researchers at first blamed the failure on the
use of adenovirus 5 as the carrier for three HIV genes designed to stimulate immunity to HIV.
