Deliberate stimulation of the host's immune response. ACTIVE IMMUNIZATION involves administration of ANTIGENS or IMMUNOLOGIC ADJUVANTS. PASSIVE IMMUNIZATION involves administration of IMMUNE SERA or LYMPHOCYTES or their extracts (e.g., transfer factor, immune RNA) or transplantation of immunocompetent cell producing tissue (thymus or bone marrow).
The production of PEPTIDES or PROTEINS by the constituents of a living organism. The biosynthesis of proteins on RIBOSOMES following an RNA template is termed translation (TRANSLATION, GENETIC). There are other, non-ribosomal peptide biosynthesis (PEPTIDE BIOSYNTHESIS, NUCLEIC ACID-INDEPENDENT) mechanisms carried out by PEPTIDE SYNTHASES and PEPTIDYLTRANSFERASES. Further modifications of peptide chains yield functional peptide and protein molecules.
Proteins found mainly in icosahedral DNA and RNA viruses. They consist of proteins directly associated with the nucleic acid inside the NUCLEOCAPSID.

A family of basic helix-loop-helix transcription factors that control expression of a variety of GENES involved in CELL CYCLE regulation. E2F transcription factors typically form heterodimeric complexes with TRANSCRIPTION FACTOR DP1 or transcription factor DP2, and they have N-terminal DNA binding and dimerization domains. E2F transcription factors can act as mediators of transcriptional repression or transcriptional activation.

Late transcription and simultaneous replication of simian adenovirus 7 DNA as revealed by spreading lytically infected cell cultures. (1/60)

Miller's technique of spreading DNA was applied to monkey cells productively infected with simian adenovirus 7. This permitted the visualization of cellular DNA transcription, both nucleolar and non-nucleolar, and of late transcription and replication of virus. Virus double-stranded DNA, thin fibres with very few nucleosome-like particles, were observed carrying either transcription or replication complexes. In addition, both RNP transcripts and replication forks were found on some virus duplex DNA. Virus single-stranded DNA replicative intermediates were identified on the basis of their increased thickness and contrast which results from the presence of a DNA binding protein.  (+info)

Biological activity of the intact and cleaved DNA of the simian adenovirus 7. (2/60)

Only the deproteinized DNA preparations of the simian adenovirus of the type 7 (SA 7) exhibited transforming and tumorigenic activity. The complex of the SA7 DNA with terminal protein (TP) did not exhibit either transforming or tumorigenic activity in cell cultures. In contrast to the transforming potential the infectious titers of the DNA - TP complex for the monkey kidney cells were 30-50 times higher than those of pure DNA. Cleavage of the SA7 DNA by specific endonucleases enhanced the tumorigenic potential of pure DNA, suppressed its infectivity and did not affect the lack of transformation capacity of the DNA - TP complex. The onc-gene was localized in the left terminal fragment with the minimal size 4,3x10(6)D in the case of R.Sal I. The tumorigenic activity was found to decrease with an increase in the size of the DNA fragment containing the onc-gene.  (+info)

Chimpanzee adenovirus CV-68 adapted as a gene delivery vector interacts with the coxsackievirus and adenovirus receptor. (3/60)

A replication-defective form of chimpanzee adenovirus type 68 (C68) has been developed to circumvent problems posed by widespread preexisting immunity to common human adenovirus vectors. To investigate the determinants of C68 tropism, its interaction with the coxsackievirus and adenovirus receptor (CAR) was studied. Although CHO cells were resistant to transduction by C68 as well as by adenovirus type 5 (Ad5), CHO cells expressing either human or murine CAR were transduced readily. C68 transduction, like Ad5 transduction, was blocked when cells were exposed to anti-CAR antibody or when virus was exposed to a soluble form of the CAR extracellular domain. These results indicate that gene delivery by C68 occurs by a CAR-dependent mechanism.  (+info)

Novel, chimpanzee serotype 68-based adenoviral vaccine carrier for induction of antibodies to a transgene product. (4/60)

An E1-deletion-containing adenoviral recombinant based on the chimpanzee serotype 68 (AdC68) was developed to express the rabies virus glycoprotein. Mice immunized with this construct (AdC68rab.gp) developed antibodies to rabies virus and remained resistant to challenge with an otherwise lethal dose of rabies virus. In naive mice immunized intranasally, the rabies virus-specific antibody responses elicited by AdC68rab.gp were comparable with regard to both titers and isotype profiles to those induced by an adenoviral recombinant based on human serotype 5 (Adhu5) expressing the same transgene product. In contrast, subcutaneous immunization with the AdC68rab.gp vaccine resulted in markedly lower antibody responses to the rabies virus glycoprotein than the corresponding Adhu5 vaccine. Antibodies from AdC68rab.gp-immunized mice were strongly biased towards the immunoglobulin G2a isotype. The antibody response to the rabies virus glycoprotein presented by Adhu5rab.gp was severely compromised in animals preexposed to the homologous adenovirus. In contrast, the rabies virus-specific antibody response to the AdC68rab.gp vaccine was at most marginally affected by preexisting immunity to common human adenovirus serotypes, such as 2, 4, 5, 7, and 12. This novel vaccine carrier thus offers a distinct advantage over adenoviral vaccines based on common human serotypes.  (+info)

Comparative sequence analysis of the largest E1A proteins of human and simian adenoviruses. (5/60)

The early region 1A (E1A) gene is the first gene expressed after infection with adenovirus and has been most extensively characterized in human adenovirus type 5 (hAd5). The E1A proteins interact with numerous cellular regulatory proteins, influencing a variety of transcriptional and cell cycle events. For this reason, these multifunctional proteins have been useful as tools for dissecting pathways regulating cell growth and gene expression. Despite the large number of studies using hAd5 E1A, relatively little is known about the function of the E1A proteins of other adenoviruses. In 1985, a comparison of E1A sequences from three human and one simian adenovirus identified three regions with higher overall levels of sequence conservation designated conserved regions (CR) 1, 2, and 3. As expected, these regions are critical for a variety of E1A functions. Since that time, the sequences of several other human and simian adenovirus E1A proteins have been determined. Using these, and two additional sequences that we determined, we report here a detailed comparison of the sequences of 15 E1A proteins representing each of the six hAd subgroups and several simian adenoviruses. These analyses refine the positioning of CR1, 2, and 3; define a fourth CR located near the carboxyl terminus of E1A; and suggest several new functions for E1A.  (+info)

A simian replication-defective adenoviral recombinant vaccine to HIV-1 gag. (6/60)

In animal models, E1-deleted human adenoviral recombinants of the serotype 5 (AdHu5) have shown high efficacy as vaccine carriers for different Ags including those of HIV-1. Humans are infected by common serotypes of human adenovirus such as AdHu5 early in life and a significant percentage has high levels of neutralizing Abs to these serotypes, which will very likely impair the efficacy of recombinant vaccines based on the homologous virus. To circumvent this problem, a novel replication-defective adenoviral vaccine carrier based on an E1-deleted recombinant of the chimpanzee adenovirus 68 (AdC68) was developed. An AdC68 construct expressing a codon-optimized, truncated form of gag of HIV-1 induces CD8(+) T cells to gag in mice which at the height of the immune response encompass nearly 20% of the entire splenic CD8(+) T cell population. The vaccine-induced immune response provides protection to challenge with a vaccinia gag recombinant virus. Induction of transgene-specific CD8(+) T cells and protection against viral challenge elicited by the AdC68 vaccines is not strongly inhibited in animals preimmune to AdHu5 virus. However, the response elicited by the AdHu5 vaccine is greatly attenuated in AdHu5 preimmune animals.  (+info)

Complete nucleotide sequences and genome organization of four chimpanzee adenoviruses. (7/60)

The complete nucleotide sequences for four adenoviruses-Simian Adenoviruses 21, 22, 23, and 24, originally isolated from chimpanzees, were determined. The genome organization of the chimpanzee adenoviruses was found to be similar to that of other adenoviruses. The viral gene products of the adenoviruses Simian Adenoviruses 22, 23, and 24 are very closely related to those of the (previously sequenced) chimpanzee adenovirus Simian Adenovirus 25. Simian Adenovirus 21 is most similar to human subgroup B adenoviruses HAdV-3, HAdV-7, and HAdV-35. Analysis of the capsid proteins hexon and fiber of the chimpanzee adenoviruses also supports the placement of Simian Adenovirus 21 in subgroup B and Simian Adenoviruses 22, 23, and 24 in subgroup E.  (+info)

Analysis of the first complete genome sequence of an Old World monkey adenovirus reveals a lineage distinct from the six human adenovirus species. (8/60)

Simian adenovirus 3 (SAdV-3) is one of several adenoviruses that were isolated decades ago from Old World monkeys. Determination of the complete DNA sequence of SAdV-3 permitted the first full genomic comparison of a monkey adenovirus with adenoviruses of humans (HAdVs) and chimpanzees, which are recognized formally as constituting six of the species (HAdV-A to HAdV-F) within the genus Mastadenovirus. The SAdV-3 genome is 34 246 bp in size and has a G+C content of 55.3 mol%. It contains all the genes that are characteristic of the genus Mastadenovirus and has a single VA-RNA gene and six genes in each of the E3 and E4 regions. The genetic organization is the same as that of HAdV-12, a member of the HAdV-A species. Phylogenetic analyses showed that although SAdV-3 is related marginally more closely to HAdV-A and HAdV-F than to other species, it represents a unique lineage that branched at an early stage of primate adenovirus divergence. The results imply that the genetic layout in SAdV-3 and HAdV-12 may also have characterized the common ancestor of all sequenced primate adenoviruses.  (+info)

Last year, Chiu and colleagues also identified another new adenovirus, named simian adenovirus C, which sickened four of nine captive baboons and killed two of them at a primate facility in 1997. Several staff members at the facility also complained of upper respiratory symptoms at the time of the outbreak. Re-examining the samples many years later, Chiu and his colleagues found antibodies targeted to simian adenovirus C in the human samples.. Chiu concluded that staff members had been exposed to the new virus, and that the virus may have jumped from baboon to human, an idea also supported by follow-up experiments in which laboratory strains of simian adenovirus C efficiently infected both human and baboon cells.. Adenoviruses to date have not generally been linked to cross-species infections between monkeys and humans, Chiu said.. In light of these findings, however, he said the normal vigilance in tracking animal viruses that might also infect humans should extend beyond influenza and ...

Some of the volunteers will receive a booster vaccination with MVA CS administered via intramuscular route. Safety data will be collected for each vaccination regimen. Secondary aim of this study will be to assess the immune responses generated by vaccination ...
Virus diversity and escape from immune responses are the biggest challenges to the development of an effective vaccine against HIV-1. We hypothesized that T-cell vaccines targeting the most conserved regions of the HIV-1 proteome, which are common to most variants and bear fitness costs when mutated, will generate effectors that efficiently recognize and kill virus-infected cells early enough after transmission to potentially impact on HIV-1 replication and will do so more efficiently than whole protein-based T-cell vaccines. Here, we describe the first-ever administration of conserved immunogen vaccines vectored using prime-boost regimens of DNA, simian adenovirus and modified vaccinia virus Ankara to uninfected UK volunteers. The vaccine induced high levels of effector T cells that recognized virus-infected autologous CD4 + cells and inhibited HIV-1 replication by up to 5.79 log 10. The virus inhibition was mediated by both Gag- and Pol- specific effector CD8 + T cells targeting epitopes that are
While chimpanzees can give insight into common illnesses, they can also be integral in the development of vaccines. Adenoviruses (Ads), a type of double-stranded DNA virus that broadly infects vertebrates, have historically been used as vaccine vectors.[21] Although human serotypes of adenovirus (AdHus) have frequently been used, studies of chimpanzee adenoviruses (AdCs) are rising in prevalence due to a number of apparent benefits, including increased immunogenicity and a decrease in neutralizing cell responses in comparison to human adenoviral vectors.[21] [23] Chimpanzee adenovirus vectors have been developed in response to a number of pervasive and otherwise common diseases; in response to the 2016 Ebola outbreak, for example, researchers developed AdCs that successfully activated memory T-cell responses, distributed equally between CD4 and CD8 T-cells.[21] [23] In January 2017, the Coalition for Epidemic Preparedness Innovations (CEPI) was formed with the purpose of creating and stockpiling ...

The Oxford / AstraZeneca vaccine does not use the revolutionary genetic technology of mRNA or messenger RNA like Pfizer and Moderna, but the more traditional virus-vector type that takes as a carrier another virus (a chimpanzee adenovirus) although genetically modified and adapted to combat Covid-19.. However, it has been criticized due to the confusion in the interim results of clinical trials. The British laboratory announced in November that its vaccine had an average efficacy of 70%, compared to more than 90% for the Pfizer / BioNTech and Moderna vaccines.. The efficacy of the AstraZeneca / Oxford vaccine was 90% for volunteers who received a half dose first and then a full dose one month later, but only 62% for another group that was more frequently vaccinated with two full doses with a month difference.. The half-dose injection was, in fact, due to an error and only a small group had followed the second protocol, which had raised concern, and led the company to announce on November 26 ...

BACKGROUND: Circumsporozoite protein (CS) is the antigenic target for RTS,S, the most advanced malaria vaccine to date. Heterologous prime-boost with the viral vectors simian adenovirus 63 (ChAd63)-modified vaccinia virus Ankara (MVA) is the most potent inducer of T-cells in humans, demonstrating significant efficacy when expressing the preerythrocytic antigen insert multiple epitope-thrombospondin-related adhesion protein (ME-TRAP). We hypothesized that ChAd63-MVA containing CS may result in a significant clinical protective efficacy. METHODS: We conducted an open-label, 2-site, partially randomized Plasmodium falciparum sporozoite controlled human malaria infection (CHMI) study to compare the clinical efficacy of ChAd63-MVA CS with ChAd63-MVA ME-TRAP. RESULTS: One of 15 vaccinees (7%) receiving ChAd63-MVA CS and 2 of 15 (13%) receiving ChAd63-MVA ME-TRAP achieved sterile protection after CHMI. Three of 15 vaccinees (20%) receiving ChAd63-MVA CS and 5 of 15 (33%) receiving ChAd63-MVA ME-TRAP

Background: Nearly 3 million people worldwide are coinfected with HIV and HCV. Affordable strategies for prevention are needed. We developed a novel vaccination regimen involving replication-defective and serologically distinct chimpanzee adenovirus (ChAd3, ChAd63) vector priming followed by modified vaccinia Ankara (MVA) boosts, for simultaneous delivery of HCV non-structural (NSmut) and HIV-1 conserved (HIVconsv) region immunogens. Methods: We conducted a phase I trial in which 33 healthy volunteers were sequentially enrolled and vaccinated via the intramuscular route as follows: 9 received ChAd3-NSmut [2.5 × 1010 vp] and MVA-NSmut [2 × 108 pfu] at weeks 0 and 8, respectively; 8 received ChAdV63.HIVconsv [5 × 1010 vp] and MVA.HIVconsv [2 × 108 pfu] at the same interval; 16 were co-primed with ChAd3-NSmut [2.5 × 1010 vp] and ChAdV63.HIVconsv [5 × 1010 vp] followed at week 8 by MVA-NSmut and MVA.HIVconsv [both 1 × 108 pfu]. Immunogenicity was assessed using peptide pools in ex vivo ELISpot and
A malaria transmission-blocking vaccine would be a critical tool in achieving malaria elimination and eradication. Using chimpanzee adenovirus serotype 63 and modified vaccinia virus Ankara viral vectored vaccines, we investigated whether incorporating two antigens into one vaccine would result in higher transmission-reducing activity than one antigen. We demonstrated that when Pfs25 was administered with other antigens Pfs28 or Pfs230C, either concurrently, as a mixed vaccine, or co-expressed as a dual-antigen vaccine, the antibody response in mice to each antigen was comparable to a mono-antigen vaccine, without immunological interference. However, we found that the transmission-reducing activity (functional activity) of dual-antigen vaccines was not additive. Dual-antigen vaccines generally only elicited similar transmission-reducing activity to mono-antigen vaccines, and in one instance had lower transmission-reducing activity. We found that despite the lack of immunological interference of dual

The flavivirus envelope protein domain III (EDIII) was an effective immunogen against dengue virus (DENV) and other related flaviviruses. Whether this can be applied to the Zika virus (ZIKV) vaccinology remains an open question. Here, we tested the efficacy of ZIKV-EDIII against ZIKV infection, using several vaccine platforms that present the antigen in various ways. We provide data demonstrating that mice vaccinated with a ZIKV-EDIII as DNA or protein-based vaccines failed to raise fully neutralizing antibodies and did not control viremia, following a ZIKV challenge, despite eliciting robust antibody responses. Furthermore, we showed that ZIKV-EDIII encoded in replication-deficient Chimpanzee adenovirus (ChAdOx1-EDIII) elicited anti-ZIKV envelope antibodies in vaccinated mice but also provided limited protection against ZIKV in two physiologically different mouse challenge models. Taken together, our data indicate that contrary to what was shown for other flaviviruses like the dengue virus, which has

There is an urgent need to develop new tuberculosis (TB) vaccines to safely and effectively boost Bacille Calmette-Guérin (BCG)-triggered T cell immunity in humans. AdHu5Ag85A is a recombinant human type 5 adenovirus (AdHu5)-based TB vaccine with demonstrated efficacy in a number of animal species, yet it remains to be translated to human applications. In this phase 1 study, we evaluated the safety and immunogenicity of AdHu5Ag85A in both BCG-naïve and previously BCG-immunized healthy adults. Intramuscular immunization of AdHu5Ag85A was safe and well tolerated in both trial volunteer groups. Moreover, although AdHu5Ag85A was immunogenic in both trial volunteer groups, it much more potently boosted polyfunctional CD4+ and CD8+ T cell immunity in previously BCG-vaccinated volunteers. Furthermore, despite prevalent preexisting anti-AdHu5 humoral immunity in most of the trial volunteers, we found little evidence that such preexisting anti-AdHu5 immunity significantly dampened the potency of ...

Fourteen months after it was acquired by Google, the seminal video sharing website Chen and Hurley started in February 2005 is more relevant than ever, its unique users and page views spiking 83% and 200% respectively from September 2006 to September 2007.
Human adenoviruses are non-enveloped dsDNA viruses of almost 35 kb in size [1]. HAdV can infect a variety of tissues and cause a wide range of complications like gastroenteritis, hepatitis, myocarditis, keratoconjunctivitis and pneumonia [2, 3]. It is contagion in nature which occurs through direct contact or fomites and virus is also resistant to various physical and chemical agents. Children younger than the age of 5 years and immune compromised persons especially the pediatric patients are most susceptible to these viruses. Worldwide 5-7% respiratory tract infections are ascribed by HAdV in pediatric patients [4] and persons of all ages are susceptible to infections caused by these viruses [5].. Seven known Human adenoviruses species from HAdV-A to HAdV-G are constitute of the genus Mastadenovirus in which all the human adenoviruses are categorized and further divided into different strains [6]. Now 67 types of HAdV have been reported [7]. Their number is rapidly increasing due to ...
Human adenovirus (HAdV) is a common pathogen causing a broad spectrum of diseases. HAdV encodes the pVII protein, which is involved in nuclear delivery, protection and expression of viral DNA. To suppress the cellular interferon (IFN) and RNA interference (RNAi) systems, HAdVs encode non-coding virus-associated (VA) RNAs. In this thesis we have investigated the functional significance of the pVII protein and VA RNAI in HAdV-5 infected cells.. We report that the propeptide module is the destabilizing element targeting the precursor pVII protein for proteasomal degradation. We also found that the Cul3-based E3 ubiquitin ligase complex alter the precursor pVII protein stability via binding to the propeptide sequence. In addition, we show that inhibition of the Cul3 protein reduces HAdV-5 E1A gene expression. Collectively, our results suggest a novel function for the pVII propeptide module and involvement of Cul3 in viral E1A gene expression.. Our studies show that the cellular E3 ubiquitin ligase ...

Enveloped viruses fuse with host membranes without affecting cell integrity. Non-enveloped viruses and bacteria penetrate by rupturing endosomal membranes and thus expose complex-type carbohydrates from the endosome lumen to cytosolic proteins. Here we report on the dynamics and initial marker analyses of Galectin-3 (Gal3)-positive membranes triggered by incoming adenovirus species B/C in HeLa cells. Using mCherry-Gal3 reporter constructs, immunolabeling, confocal and electron microscopy, we detected robust signals from Gal3-containing, early endosomal antigen 1-positive membranes 1 h post-infection (pi). Adenoviruses penetrate from non-acidic endosomes with high efficiency, 15 min pi, and largely outnumbered the Gal3-positive membranes, suggesting that Gal3 recruitment to broken membranes is transient, or Gal3-positive membranes are rapidly turned-over. In support of rapid turn-over, Gal3 was found within single-membrane vesicles and degradative autophagosomes. The Gal3 membranes contained ubiquitin

These DNA viruses (unlike other adenoviruses) could not be cultured using standard virus culture systems. The most frequent are types 40 and 41. These enteric adenovirus species are the second most common cause of severe gastroenteritis in young children (after rotavirus), comprising about 10%-15% of cases (range, 5%-52%). It has also been the second or third most common overall cause of infant gastroenteritis. Diarrhea is the predominant symptom. Vomiting may be present but is less prominent than that seen in rotavirus infection. The gold standard for diagnosis has been EM of stool specimens. However, EM cannot differentiate between fastidious and other adenovirus species. Culture can be done in some cases using nonroutine tissue culture cells. Several EIA tests for virus antigen in stool have been described and one commercial kit for types 40 and 41 is now available. Nucleic acid probes have also been used experimentally.. ...
Programmable magnetic nanobots injected into the vascular and interstitial fluids of a human or animal body are found to be deposited into the connective and fatty tissues and then into the organs and glands potentially causing biological transformation of the cell membrane (crowning and protein spiking), genetic mutation, and the death of the cell.[1][2] Nanobots can be injected using an ordinary hypodermic syringe.
