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.

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.

A recombinant E1-deleted porcine adenovirus-3 as an expression vector. (1/13)

Replication-defective E1-deleted porcine adenoviruses (PAVs) are attractive vectors for vaccination. As a prerequisite for generating PAV-3 vectors containing complete deletion of E1, we transfected VIDO R1 cells (fetal porcine retina cells transformed with E1 region of human adenovirus 5) with a construct containing PAV-3 E1B(large) coding sequences under the control of HCMV promoter. A cell line named VR1BL could be isolated that expressed E1B(large) of PAV-3 and also complemented PAV214 (E1A+E1B(small) deleted). The VR1BL cells could be efficiently transfected with DNA and allowed the rescue and propagation of recombinant PAV507 containing a triple stop codon inserted in the E1B(large) coding sequence. In addition, recombinant PAV227 containing complete deletion of E1 (E1A+E1B(small) + E1B(large)) could be successfully rescued using VR1BL cell line. Recombinant PAV227 replicated as efficiently as wild-type in VR1BL cells but not in VIDO R1 cells, suggesting that E1B(large) was essential for replication of PAV-3. Next, we constructed recombinant PAV219 by inserting green fluorescent (GFP) protein gene flanked by a promoter and a poly(A) in the E1 region of the PAV227 genome. We demonstrated that PAV219 was able to transduce and direct expression of GFP in some human cell lines.  (+info)

Characterization of cis-acting sequences involved in packaging porcine adenovirus type 3. (2/13)

Encapsidation of adenovirus DNA involves specific interactions between cis-acting genomic DNA sequences and trans-acting proteins. The cis-acting packaging domain located near the left inverted terminal repeat is composed of a series of redundant but not functionally equivalent motifs. Such motifs are made up of the consensus sequence 5'-TTTGN(8)CG-3' and 5'-TTTG/A-3' in human adenovirus 5 (HAV-5) and canine adenovirus-2 (CAV-2), respectively. To gain comparative insight into adenovirus encapsidation, we examined the packaging domain of porcine adenovirus-3 (PAV-3). Using deletion mutants, we localized the PAV-3 packaging domain to 319 bp (nt 212 to 531), which contains six cis-acting elements. However, this domain does not contain the consensus motifs identified in HAV-5. In addition, consensus motif found in CAV-2 is present only once in PAV-3. Instead, PAV-3 packaging domain appears to contain AT/GC-rich sequences. The packaging motifs of PAV-3, which are functionally redundant but not equivalent, are located at the left end of the genome.  (+info)

Porcine adenovirus type 3 E1 transcriptional control region contains a bifunctional regulatory element. (3/13)

We identified a bifunctional regulatory element located between nt 374 and 431 upstream of TATA box of porcine adenovirus (PAV) 3 E1A promoter. Deletion of the element dramatically reduced the steady-state level of E1A mRNA, but increased that of E1B, which lies immediately downstream of E1A. The mutant virus displayed defective replication at early times of infection, but replicated nearly as efficiently as wild-type PAV-3 at late times of infection. This defect was complemented with coinfecting wild-type virus in a mixed infection. The results indicated that the upstream activation sequences (UAS) of E1A overlap the upstream repression sequences (URS) of E1B, although both transcription units are transcribed from different promoters.  (+info)

Detection of bovine and porcine adenoviruses for tracing the source of fecal contamination. (4/13)

In this study, a molecular procedure for the detection of adenoviruses of animal origin was developed to evaluate the level of excretion of these viruses by swine and cattle and to design a test to facilitate the tracing of specific sources of environmental viral contamination. Two sets of oligonucleotides were designed, one to detect porcine adenoviruses and the other to detect bovine and ovine adenoviruses. The specificity of the assays was assessed in 31 fecal samples and 12 sewage samples that were collected monthly during a 1-year period. The data also provided information on the environmental prevalence of animal adenoviruses. Porcine adenoviruses were detected in 17 of 24 (70%) pools of swine samples studied, with most isolates being closely related to serotype 3. Bovine adenoviruses were present in 6 of 8 (75%) pools studied, with strains belonging to the genera Mastadenovirus and Atadenovirus and being similar to bovine adenoviruses of types 2, 4, and 7. These sets of primers produced negative results in nested PCR assays when human adenovirus controls and urban-sewage samples were tested. Likewise, the sets of primers previously designed for detection of human adenovirus also produced negative results with animal adenoviruses. These results indicate the importance of further studies to evaluate the usefulness of these tests to trace the source of fecal contamination in water and food and for environmental studies.  (+info)

Viral RNAs detected in virions of porcine adenovirus type 3. (5/13)

It has been demonstrated that cellular and viral RNAs were packaged in the virions of human cytomegalovirus (CMV) and herpes simplex virus 1 (HSV 1), members of the Herpesviridae family, both of which are enveloped double-stranded DNA viruses. Here, we provide evidence suggesting that RNAs are packaged in the virions of porcine adenovirus type 3 (PAdV-3), which is a member of the Adenoviridae family, a non-enveloped double-stranded DNA virus. The RNAs packaged in PAdV-3 virions were enriched in the size range of 300-1000 bases long. By reverse transcription (RT) of RNAs isolated from purified PAdV-3 virions, PCR amplification, and DNA sequence analysis of PCR products, we determined the identities of some viral RNAs contained in PAdV-3 virions. The results indicated that the RNAs representing transcripts from E1A, E1B, DNA binding protein (DBP), DNA polymerase (POL), E4 and some of the late genes including pIIIA, pIII, pV, Hexon, 33 K, and fiber were detected from purified PAdV-3 virions. In contrast, we could not detect the RNAs representing transcripts of precursor terminal protein (pTP), 52 kDa, pX, or 100-kDa protein genes in purified virions. Because the transcripts of pIX, IVa2, E3, protease, pVI, pVII, and pVIII overlap with those of other genes in PAdV-3, we could not definitely conclude that RNAs representing these transcripts were packaged in virions although the expected DNA fragments were produced by RT-PCR in the RNAs isolated from purified virions.  (+info)

Porcine adenovirus serotype 3 internalization is independent of CAR and alphavbeta3 or alphavbeta5 integrin. (6/13)

Nonhuman adenoviruses including porcine adenovirus serotype 3 (PAd3) are emerging vectors for gene delivery. PAd3 efficiently transduces human and murine cells in culture, and circumvents preexisting humoral immunity in humans. The coxsackievirus-adenovirus receptor (CAR) serves as a primary receptor and alphavbeta3 or alphavbeta5 integrin as a secondary receptor for several human adenovirus (HAd) subtypes including HAd5. In this study, we deduced the role of CAR, alphavbeta3 or alphavbeta5 integrin in PAd3 internalization. Transduction experiments were conducted in human mammary epithelial (MCF-10A) cells using replication-defective PAd-GFP (PAd3 vector expressing green fluorescent protein [GFP]) and HAd-GFP (HAd5 vector expressing GFP). MCF-10A cells were treated with or without anti-human CAR, or anti-alphavbeta3 or anti-alphavbeta5 integrin antibodies prior to infection with HAd-GFP or PAd-GFP. Significant (P <0.05) inhibition in transduction by HAd-GFP was observed in antibody-treated cells as compared to untreated cells, whereas transduction by PAd-GFP remained to similar levels irrespective of the treatment. To study the adenoviral fiber knob-mediated virus interference, MCF-10A cells were treated with or without the recombinant HAd5 or PAd3 knob followed by infection with HAd-GFP or PAd-GFP. Significant (P <0.05) inhibition was observed only in transduction of the homologous vector. These results suggested that PAd3 internalization was CAR- as well as alphavbeta3 or alphavbeta5 integrin-independent and the primary receptor for HAd5 and PAd3 were distinct. CAR- and alphavbeta3 or alphavbeta5 integrin-independent entry of PAd3 vectors may have implications in targeting cell types that are not efficiently transduced by other adenoviral vectors.  (+info)

A newly identified interaction between IVa2 and pVIII proteins during porcine adenovirus type 3 infection. (7/13)

The adenovirus IVa2 is an intermediate viral gene product that appears to perform multiple essential roles in viral infection. Using IVa2 as bait in the yeast two-hybrid system, we screened selected open reading frames (ORFs) of porcine adenovirus (PAdV)-3 for potential interaction with IVa2. Interestingly, pVIII showed specific interaction with IVa2. The yeast two-hybrid findings were validated by GST pull-down assays, in vitro binding studies employing cell-free coupled transcription-translation products and in vitro co-immunoprecipitations using protein-specific antibodies. Finally, we demonstrated that IVa2 specifically interacts with pVIII during PAdV-3 infection.  (+info)

Porcine adenovirus type 3 E1B large protein downregulates the induction of IL-8. (8/13)

Replication-defective (E1-E3 deleted) adenovirus vector based gene delivery results in the induction of cytokines including IL-8, which may contribute to the development of inflammatory immune responses. Like other adenoviruses, E1 + E3 deleted porcine adenovirus (PAdV) 3 induces the production of IL-8 in infected cells. In contrast, no IL-8 production could be detected in cells infected with wild-type or mutant PAdV-3s containing deletion in E1A + E3 (PAV211) or E1Bsmall + E3 (PAV212). Expression of PAdV-3 E1Blarge inhibited the NF-kappaB dependent transcription of luciferase from IL-8 promoter. Imunofluorescence and electrophoretic mobility shift assays suggested that constitutive expression of PAdV-3 E1Blarge inhibited the nuclear translocation of NF-kappaB and its subsequent binding to DNA. These results suggest that E1Blarge interacts with NF-kappaB to prevent transcription and down regulate proinflammatory cytokine IL-8 production.  (+info)

Purpose: One of the key limiting parameters in the penetration and effectiveness of topically applied ocular therapeutics is their mean residence time. Most of an instilled solution clears through drainage, with first-order clearance about 4 times that of bulk tear flow (~5 ul/min). For protein drugs, the problem becomes more acute due to the additional burden of reduced penetrance through the cornea and conjunctiva. Residence time might be increased however by fusing a protein of interest to a mucosal surface binding protein, such as galectin-3 (gal-3). Gal-3 is a small pentameric ocular surface resident protein that cross-links O-type mucins.. Methods: We used Gaussia luciferase (luc) as our test protein, fused at its N-terminus to one or 2 copies of the carbohydrate binding domain of gal-3 (gal). Fusions were expressed in HEK cells and purified by IMAC chromatography, and evaluated mucin binding by ELISA and by their ocular surface half-lives on mouse eyes and rabbit corneas, using luciferase ...

The monumental 2017 publication, Arts of Living on a Damaged Planet, invites readers to learn new ways to understand ourselves in the face of unprecedented social and ecological turmoil.. As part of this rethinking, scholars marshal research that upends the most fundamental unit of biological and social analysis - the individual. Building from the work of famed University of Massachusetts Amherst Professor Lynn Margulis, one essay shows the proliferation and importance of nonhuman cells that comprise human bodies. Another essay proposes that evolution depends in part on relationships between species, and not simply individual fitness. And yet another essay argues that collective behavior might best be understood as an emergent process, rather than as a planned outcome.. These growing scientific insights are profound. They suggest that our very existence depends not on individual success, but on a deepening understanding of and attunement to our interrelationships with others - both human and ...

We evaluated the prevalence of hepatitis E virus (HEV) in the pork production chain in Czech Republic, Italy, and Spain during 2010. A total of 337 fecal, liver, and meat samples from animals at slaughterhouses were tested for HEV by real-time quantitative PCR. Overall, HEV was higher in Italy (53%) and Spain (39%) than in Czech Republic (7.5%). HEV was detected most frequently in feces in Italy (41%) and Spain (39%) and in liver (5%) and meat (2.5%) in Czech Republic. Of 313 sausages sampled at processing and point of sale, HEV was detected only in Spain (6%). HEV sequencing confirmed only g3 HEV strains. Indicator virus (porcine adenovirus) was ubiquitous in fecal samples and absent in liver samples and was detected in 1 slaughterhouse meat sample. At point of sale, we found porcine adenovirus in sausages (1%-2%). The possible dissemination of HEV and other fecal viruses through pork production demands containment measures ...
Dear AAP Pediatricians, As a physician, scientist, and father of a vaccine-injured child, I have many issues with Offit and Moser�s critique of Dr. Sears vaccine book, particularly its authoritarian tone and content. Offit is certainly entitled to his opinion, but it must be recognized as that. We must stick to the science and recognize the open questions with regards to vaccine safety. Excerpt from Offit and Moser article: {Sears has a poor grasp of the scientific method. Some studies have been published in recent years that have failed to show statistical proof of a relationship between vaccines and autism, he writes. However, by the same token, it is also difficult to prove that there is not a connection. Using the scientific method, investigators form the null hypothesis. Good epidemiological studies are powered to reject or not to reject the null hypothesis. However, the scientific method does not allow investigators to accept the null hypothesis. Said another way, scientists can ...
Cells derived from different organisms and tissues have been established and are used in bioresearch and for the production of complex biological products. The cell lines can be grown in labs for extended periods, but changes in the DNA sequence and biological responses of the cells can occur. The changes in the cell lines during culturing or inadvertent mixing or mislabeling cannot be readily identified by their appearance under a microscope. A major issue has continued to plague the scientific community for over 50 years: cell line contamination and misidentification. Human cell lines can be identified by existing multiplex polymerase chain reaction (PCR) assays that target short tandem repeat (STR) markers in DNA that are used as fingerprints for authentication. Methods to authenticate nonhuman cell lines are lacking. Our efforts have focused on developing methods for authentication of important nonhuman cell lines to achieve measurement assurance of their use.
M2.DM.17.4769) A five-year-old boy presents with his mother to your clinic complaining of a fever and rash. His mother says the patient was in his usual state of health until two weeks ago when he developed strep throat. He was prescribed a ten day treatment with oral amoxicillin by his primary care physician, which he has since completed. The mother reports that he seemed to feel better until two days ago when he began to complain of joint pain and an itchy rash. His mother notes the patient is on an alternative vaccine schedule. She is nervous because her son attends day-care three days a week, and there has been a recent viral outbreak. The patients temperature is 103°F (39.4°C), blood pressure is 99/59 mmHg, pulse is 110/min, and respirations are 20/min with an oxygen saturation of 99% O2 on room air. On physical exam, you note cervical adenopathy, joint swelling, mild peripheral edema, and a diffuse rash (shown in Figure A). Which of the following is the best treatment for this ...
Flaviviruses were proposed to prevent rather than to induce host translation shutoff (36, 37, 40). Several technical aspects might explain this difference from our findings, including the use of nonhuman cells, different DENV serotype 2 strains, and time points p.i. chosen for analysis. Of note, polysome profiles of Huh7 cells infected with the DENV serotype 2 Bangkok strain 16681 (40) revealed in our experiments a similar translation repression to that induced by DENV1 infection (see Fig. 1F for reference), which also correlated with reduced cytopathic effect in Huh7 cells (data not shown). Analyses of human cells early p.i. by polysome profiling identified host cell translation repression as a new feature of flavivirus infection.. Flaviviruses actively block eIF2α-mediated stress response at different levels, supposedly to avoid the associated host translation suppression. First, WNV and DENV inhibit SG formation in nonhuman cells (36). Consistently, we observed that DENV and WNV, as well as ...
Since were on the note of breastfeeding, let me tell you new mommies how important chlorella is for you specifically. Breastfeeding provides your baby with a huge extra load of nutrients and boosts his/her immunity. The exact composition of breast milk changes with each feeding to adapt to your individual babys needs. A study in Japan followed 35 breast-feeding mothers. Eighteen of them took chlorella supplements and were compared to the rest. Breast milk from mothers who supplemented with chlorella had higher concentrations of Immunoglobulin A (IgA), which is an antibody. These antibodies help prevent viruses, bacteria and fungus from creating infections (very important if you are doing an alternative vaccine schedule, or choosing not to vaccinate at this time). IgA, in particular, helps protect the surfaces of the body that are exposed to foreign substances like the nose, digestive tract, eyes, ears, saliva and tears. This is a big advantage to young babies. This same Japanese study showed ...

Infectious bronchitis virus (IBV) causes an acute, highly contagious respiratory disease in chickens, which results in significant economic losses in commercial flocks. One of the major hurdles associated with the control of the disease is the continued emergence of new serotypes/variants due to mutation or recombination. This also makes the diagnosis of disease using conventional serological methods difficult. Therefore, there is a need for alternative vaccines and serotyping methods. ^ A multiplex PCR for Massachusetts and Arkansas serotypes of IBV was developed. Two serotype specific PCR products, 1026 bp for Massachusetts and 896 bp for Arkansas were amplified; the detection limits for both were 5 pg of viral RNA. By testing different isolates/serotypes of IBV and other avian bacterial and viral pathogens, the high specificity of the multiplex PCR was demonstrated. In addition, its ability to detect Massachusetts and Arkansas as co-infections was revealed. ^ To explore the potential use of
The vaccine. There are two possible vaccines for Japanese encephalitis. Ideally, they need to be completed a month before you leave. One vaccine requires two doses, with the second dose given 28 days after the first. This vaccine is only suitable for people who are over 18 years of age. The alternative vaccine consists of three doses, and is suitable for people who are over one year of age. The second dose is given after seven days, and the third dose is given 21 days after this. This vaccine needs to be completed at least 10 days before you leave, in case you have an allergic reaction. Both vaccines will require a booster after one year. The Japanese encephalitis vaccine is not suitable for children who are under one year of age.. If there is not enough time to complete a normal course of the vaccine, you may be able to have an accelerated course. This involves two doses being given one week apart, or three doses with a week in between each dose. This still needs to be completed at least 10 ...
Pneumococcal surface protein A (PspA) and pneumococcal surface protein C (PspC) are important candidates for an alternative vaccine against pneumococcal infections. Since these antigens show variability, the use of variants that do not afford broad protection may lead to the selection of vaccine escape bacteria. Epitopes capable of inducing antibodies with broad cross-reactivities should thus be the preferred antigens. In this work, experiments using peptide arrays show that most linear epitopes recognized by antibodies induced in mice against different PspAs were located at the initial 44 amino acids of the mature protein and that antibodies against these linear epitopes did not confer protection against a lethal challenge. Conversely, linear epitopes recognized by antibodies to PspC included the consensus sequences involved in the interaction with human factor H and secretory immunoglobulin A (sIgA). Since linear epitopes of PspA were not protective, larger overlapping fragments containing 100 ...

Mycobacterium tuberculosis (MTB), which is the causative agent of tuberculosis (TB), is among the most important infectious bacteria with high morbidity and mortality rates worldwide. Bacilli Calmette-Guerin (BCG) vaccine has been discovered for about a century, and it is considered as a major vaccine for humans. However, some factors, such as its attenuated nature and its inefficacy against the latent form of the disease, have led to the use of alternative vaccines. Multi-epitope subunit vaccines are new-generation vaccines that are being developed in clinical trial phases. For the production of a subunit vaccine, the selection of immunodominant antigens and targeted delivery systems to antigen presenting cells (APCs) are considered as basic parameters. In the present study, we designed the novel multi-epitope ESAT-6:Ag85B:Fcγ2a, which was evaluated completely by various online tools as an optimum vaccine against TB. The early secreted antigenic target of 6 kDa (ESAT-6) and antigen 85B (Ag85B)
The BCG vaccine has been widely available for several decades. It is easy and cheap to produce, and when given to neonates or young children it is effective in preventing severe manifestations of disease such as meningeal tuberculosis and miliary tuberculosis. However, in terms of the capacity of the vaccine to protect adult humans it shows a wide range of efficacy, including zero levels of protection. Due to the general realization that BCG is losing its protective effect, particularly in terms of preventing adult-onset tuberculosis, a major effort has been made to try to develop new alternative vaccines. One such candidate, Mtb72F/AS02A, is a polyprotein derived from two known M. tuberculosis antigens adjuvanted with AS02A. Mtb72F/AS02A is a candidate TB vaccine under development for two indications: prevention of primary TB infection in young children in highly endemic areas and as an adjunct to treatment for TB in adolescents and adults ...
Vertical transmission from an infected cow to its fetus accounts for the vast majority of new Neospora caninum infections in cattle. A vaccine composed of a chimeric antigen named recNcMIC3-1-R, based on predicted immunogenic domains of the two microneme proteins NcMIC1 and NcMIC3, the rhoptry protein NcROP2, and emulsified in saponin adjuvants, significantly reduced the cerebral infection in non-pregnant BALB/c mice. Protection was associated with a mixed Th1/Th2-type cytokine response. However, the same vaccine formulation elicited a Th2-type immune response in pregnant mice and did not prevent vertical transmission or disease, neither in dams nor in offspring mice. In this study, an alternative vaccine formulation containing recNcMIC3-1-R emulsified in Freunds incomplete adjuvant, a stimulator of the cellular immunity, was investigated. No protection against vertical transmission and cerebral infection in the pregnant mice and a very limited protective effect in the non-pregnant mice were observed.

Human immunodeficiency virus-type 1 (HIV-1) entry requires fusion cofactors on the CD4+ target cell. Fusin, a heterotrimeric GTP-binding protein (G protein)-coupled receptor, serves as a cofactor for T cell line-tropic isolates. The chemokines RANTES, MIP-1α, and MIP-1β, which suppress infection by macrophage-tropic isolates, selectively inhibited cell fusion mediated by the corresponding envelope glycoproteins (Envs). Recombinant CC CKR5, a G protein-coupled receptor for these chemokines, rendered CD4-expressing nonhuman cells fusion-competent preferentially with macrophage-tropic Envs. CC CKR5 messenger RNA was detected selectively in cell types susceptible to macrophage-tropic isolates. CC CKR5 is thus a fusion cofactor for macrophage-tropic HIV-1 strains. ...
