Abstract
Haemorrhagic enteritis is an economically significant disease reported in the majority of the countries where turkeys are raised intensively; it is caused by Turkey adenovirus 3 (TAdV-3). The aim of this study was to analyse and compare the ORF1 gene 3' region from turkey haemorrhagic enteritis virus (THEV) vaccine-like and field strains in order to develop a molecular diagnostic method to differentiate the strains from each other. Eighty samples were analysed by sequencing and phylogenetic analyses using a new set of polymerase chain reaction (PCR) primers targeting a genomic region spanning the partial ORF1, hyd and partial IVa2 gene sequences. A commercial live vaccine was also included in the analysis. The results showed that 56 of the 80 sequences obtained in this study showed ≥99.8% nucleotide identity with the homologous vaccine strain sequence. Three non-synonymous mutations - ntA1274G (aaI425V), ntA1420C (aaQ473H) and ntG1485A (aaR495Q) - were detected in the THEV field strains but not in the vaccine strain. Phylogenetic analysis confirmed the clustering of the field and vaccine-like strains in different phylogenetic branches. In conclusion, the method employed in this study could be a useful tool towards making a correct diagnosis. The data could contribute to the knowledge of field distribution of THEV strains and increase the limited existing information available on native isolates around the world.

Human adenovirus replication and persistence in hypertrophic adenoids and palatine tonsils in children. J Med Virol 2019; 91:1250-1262.

Abstract
The role of human adenovirus (HAdV) infection in different acute diseases, such as febrile exudative tonsillitis, conjunctivitis, and pharyngoconjunctival fever is well established. However, the relationships, if any, of HAdV persistence and reactivation in the development of the chronic adenotonsillar disease is not fully understood. The present paper reports a 3-year cross-sectional hospital-based study aimed at detecting and quantifying HAdV DNA and mRNA of the HAdV hexon gene in adenoid and palatine tonsil tissues and nasopharyngeal secretions (NPS) from patients with adenotonsillar hypertrophy or recurrent adenotonsillitis. HAdV C, B, and E were detectable in nearly 50% of the patients, with no association with the severity of airway obstruction, nor with the presence of recurrent tonsillitis, sleep apnea or otitis media with effusion (OME). Despite the higher rates of respiratory viral coinfections in patients with HAdV, the presence of other viruses, including DNA and RNA viruses, had no association with HAdV replication or shedding in secretions. Higher HAdV loads in adenoids showed a significant positive correlation with the presence of sleep apnea and the absence of OME. Although this study indicates that a significant proportion (~85%) of individuals with chronic adenotonsillar diseases have persistent nonproductive HAdV infection, including those by HAdV C, B, and E, epithelial and subepithelial cells in tonsils seem to be critical for HAdV C production and shedding in NPS in some patients, since viral antigen was detected in these regions by immunohistochemistry in four patients, all of which were also positive for HAdV mRNA detection.

Abstract
Severe human adenovirus (HAdV) infections are an increasing threat for immunosuppressed individuals, particularly those who have received stem cell transplants. It has been previously hypothesized that severe infections might be due to reactivation of a persistent infection, but this hypothesis has been difficult to test owing to the lack of a permissive in vivo model of HAdV infection. Here we established a humanized mouse model that reproduces features of acute and persistent HAdV infection. In this model, acute infection correlated with high mortality, weight loss, liver pathology, and expression of viral proteins in several organs. In contrast, persistent infection was asymptomatic and led to establishment of HAdV-specific adaptive immunity and expression of early viral genes exclusively in the bone marrow. These findings validate the use of humanized mice to study acute and persistent HAdV infection and strongly suggest the presence of cellular reservoirs in the bone marrow.

Abstract
Adenoviral infection is a significant cause of morbidity and mortality in immunocompromised patients in the pediatric age group, hepatitis caused by the serotype 5 being the most common manifestation in the liver transplant recipient. The authors report a case of a 3 1/2-year-old child in whom fatal adenoviral hepatitis developed after liver transplantation for syndromic paucity of the intrahepatic bile ducts. Allograft biopsy at 14 days showed early changes of microabscesses in the parenchyma but no inclusions. Immunohistochemistry using an adenovirus-group antibody (MAB805, Chemicon International, Harrow, England), however, demonstrated nuclear positivity in hepatocytes related to and at a distance from the lesions. As antibody titers are unreliable in an immunocompromised patient and culture results take time, immunohistochemistry for adenovirus offers a rapid diagnosis. The technique is economic and has a clear advantage on the more demanding electron microscopic screening, which was performed in the case as additional evidence. Immunohistochemistry for adenovirus should be done routinely in the presence of microabscesses to differentiate the lesion from hepatitis due to cytomegalovirus. Int J Surg Pathol 3(3) :189-194, 1996

Abstract
Background Human adenoviruses of species B, C, and E (HAdV-B, –C, -E) are frequent causative agents of acute respiratory infections worldwide. As part of a surveillance program aimed at identifying the etiology of influenza-like illness (ILI) in Egypt, we characterized 105 adenovirus isolates from clinical samples collected between 2003 and 2010. Methods Identification of the isolates as HAdV was accomplished by an immunofluorescence assay (IFA) and confirmed by a set of species and type specific polymerase chain reactions (PCR). Results Of the 105 isolates, 42% were identified as belonging to HAdV-B, 60% as HAdV–C, and 1% as HAdV-E. We identified a total of six co-infections by PCR, of which five were HAdV-B/HAdV-C co-infections, and one was a co-infection of two HAdV-C types: HAdV-5/HAdV-6. Molecular typing by PCR enabled the identification of eight genotypes of human adenoviruses; HAdV-3 (n = 22), HAdV-7 (n = 14), HAdV-11 (n = 8), HAdV-1 (n = 22), HAdV-2 (20), HAdV-5 (n = 15), HAdV-6 (n = 3) and HAdV-4 (n = 1). The most abundant species in the characterized collection of isolates was HAdV-C, which is concordant with existing data for worldwide epidemiology of HAdV respiratory infections. Conclusions We identified three species, HAdV-B, -C and -E, among patients with ILI over the course of 7 years in Egypt, with at least eight diverse types circulating.

Abstract
Disseminated adenovirus infections cause significant mortality in stem cell transplanted patients and are suspected to originate from asymptomatic adenovirus persistence ("latency") in lymphocytes. The infection of three human T-lymphocyte lines (Jurkat, PM1, and CEM) with human adenovirus types of species A (HAdV-A31), B (HAdV-B3, -B11), and C (HAdV-C2, -C5) was investigated for 150 days in order to establish in vitro models for adenovirus persistence. HAdV-C5 persisted with continuous production of infectious virus progeny (about 10(7) TCID50 /ml) in PM1 cells. More than 100 copies of HAdV-C5-DNA per cell were detected by real-time PCR but hexon immunostaining showed that only 7.5% of the cells were infected ("carrier state infection"). Coxsackie and adenovirus receptor (CAR) expression was decreased in comparison to mock infected cultures suggesting selection of a semi-permissive subpopulation of PM-1 cells. By contrast, latency of HAdV-DNA (10(-3) -10(-4) copies/cell) without production of infectious virus progeny was observed in HAdV-C2 infection of PM1 and Jurkat, HAdV-A31 infection of PM1, and HAdV-B3 infection of Jurkat cells. In addition, transcription of E1A, DNA polymerase and hexon mRNA was not detected by RT-PCR suggesting an equivalent of clinical "HAdV latency." Persistence of HAdV-DNA was not observed in abortive infections of PM1 cells with HAdV-B3 and -B11 and in productive, lytical infections of Jurkat cells with HAdV-C5, HAdV-B11, and HAdV-A31. In conclusion, lytic and persistent infections with and without production of infectious virus were observed depending on the type of adenovirus. Genetic determinants for viral persistence may be investigated using these newly established infection models.

Abstract
In this study, real-time PCR was used to quantify adenovirus DNA in cell suspensions prepared from 106 right and left tonsils and 10 adenoids obtained from 57 patients who underwent routine tonsillectomies and/or adenoidectomies. Eighty-four (72.4%) tonsils and adenoids samples were positive for HAdV by real-time PCR. The viral load ranged from 2.8 × 10(2) to 2.6 × 10(6) copies/10(7) cells and varied up to sixfold between the right and left tonsils. In some cases, only one tonsil was positive and the viral load was lower in older children. Seventy-eight of 84 positive samples could be typed by sequencing of the hexon L1 region. Species C (types 1, 2, and 5) were detected in 84.1% of the patients followed by types 3 and 7 of species B (6.8%), HAdV-E4 (6.8%), and HAdV-F41 (2.3%). In one patient adenovirus C2 was found in the left tonsil and adenovirus C5 in the right tonsil. No DNA methylation was detected in either the E1A promoter or the major late promoter region of adenovirus DNA from six tonsils and adenoids samples and two clinical isolates.

Abstract
OBJECTIVE The primary aim of this study was to assess the relationship between adenovirus 36 (AD36)-specific antibodies and obesity in children. METHODS A cross-sectional study of children 8 to 18 years of age was performed. Children were classified according to BMI percentile as nonobese (<95th percentile) or obese (≥95th percentile). The presence of AD36-specific neutralizing antibodies was assessed by using the serum neutralization assay. RESULTS A total of 124 children (median age: 13.6 years) were studied. Of those children, 46% were nonobese and 54% were obese. AD36 positivity was present in 19 children (15%). The majority of children found to be AD36-positive were obese (15 [78%] of 19 children). AD36 positivity was significantly (P<.05) more frequent in obese children (15 [22%] of 67 children) than nonobese children (4 [7%] of 57 children). Among the subset of children who were obese, those who were AD36-positive had significantly larger anthropometric measures, including weight, BMI, waist circumference, and waist/height ratio. CONCLUSION These data support an association of obesity and higher body weight with the presence of neutralizing antibodies to AD36 in children. If a cause-and-effect relationship is established, it would have considerable implications for the prevention and treatment of childhood obesity.

Abstract
Hematopoietic cells are attractive targets for gene therapy, but the conventional adenovirus (Ad) vectors, based on Ad5, transduce these cells inefficiently. One reason for low permissiveness of hematopoietic cells to infection by species C Ads appears to be inefficient attachment. Vectors pseudotyped with species B fibers are clearly more efficient at transducing hematopoietic cells than Ad5. To evaluate which Ad species B type(s) would be the most efficient vector(s) for primary T-cells, B-cells and monocytes, attachment to and entry of the species B1 serotypes 3p and 7p and the species B2 serotypes 11p and 35 into primary PBMCs was studied. Ad11p and Ad35 were the only serotypes to show efficient binding and for which uptake by PBMCs could be detected. Infection of PBMCs by Ad5, Ad11p and Ad35 was compared. Expression of Ad hexons was detected in stimulated PBMCs, most frequently in T-cells, and in unstimulated monocytes, although B-cells appear to be refractory to productive infection. Replication of Ad DNA was severely restricted in most PBMCs. Neither hexon expression nor genome replication could be detected in unstimulated lymphocytes, but FISH and a real-time PCR-based assay suggested that Ad11p and Ad35 DNA reach the nucleus. Activation thus appears to be required for T-cells to be permissive to Ad gene expression. In summary, there are substantial differences between Ad3p and Ad7p on the one hand and Ad11p and Ad35 on the other, in their ability to interact with PBMCs. Ad11p and Ad35 probably represent vectors of choice for these cell types.

Abstract
Chronic papillary conjunctivitis has been described following adenoviral conjunctivitis. It is unknown however, how long adenovirus is able to persist in the tear film and conjunctiva. To determine if adenovirus persists in the ocular surface following adenoviral conjunctivitis, 304 patients with a history of adenovirus conjunctivitis from whom an adenovirus had been isolated 10 years previously were sent a questionnaire regarding persistent or recurrent symptoms and were invited to attend. Patients were examined and samples of tears and conjunctival cells were collected from both eyes using tear film washes, filter paper, and swabs, the latter for virus isolation. Extracted DNA from the ocular samples was amplified using primers for herpes simplex virus (thymidine kinase) and adenovirus (hexon) genes. Adenovirus amplicons were sequenced and compared to original serotype. Thirty patients attended, 19 of whom had persistent papillary conjunctivitis. Evidence of adenovirus DNA was detected in 17 of 30 patients, 15 of whom also had evidence of a chronic papillary conjunctivitis. Adenovirus DNA was significantly associated with papillary conjunctivitis (P = 0.03). Adenovirus amplicons were successfully sequenced from six patients. Four patients harbored type 3 adenovirus, the same serotype with which they were infected originally 10 years previously. Two patients were infected originally with adenovirus serotype 3 but the current serotype was type 4. Infection of the ocular surface with adenovirus may predispose to the development of a persistent or recurrent conjunctivitis, the presence of which, appears to be associated with evidence of long term persistence of adenovirus DNA.

Abstract
Detection of adenovirus DNA in human tonsillar T cells in the absence of active virus replication suggests that T cells may be a site of latency or of attenuated virus replication in persistently infected individuals. The lytic replication cycle of Ad5 in permissive epithelial cells (A549) was compared to the behavior of Ad5 in four human T-cell lines, Jurkat, HuT78, CEM, and KE37. All four T-cell lines expressed the integrin coreceptors for Ad2 and Ad5, but only Jurkat and HuT78 express detectable surface levels of the coxsackie adenovirus receptor (CAR). Jurkat and HuT78 cells supported full lytic replication of Ad5, albeit at a level approximately 10% of that of A549, while CAR-transduced CEM and KE37 cells (CEM-CARhi and KE37-CARhi, respectively) produced no detectable virus following infection. All four T-cell lines bind and internalize fluorescently labeled virus. In A549, Jurkat, and HuT78 cells, viral proteins were detected in 95% of cells. In contrast, only a small subpopulation of CEM-CARhi and KE37-CARhi cells contained detectable viral proteins. Interestingly, Jurkat and HuT78 cells synthesize four to six times more copies of viral DNA per cell than did A549 cells, indicating that these cells produce infectious virions with much lower efficiency than A549. Similarly, CEM-CARhi and KE37-CARhi cells, which produce no detectable infectious virus, synthesize three times more viral genomes per cell than A549. The observed blocks to adenovirus gene expression and replication in all four human T-cell lines may contribute to the maintenance of naturally occurring persistent adenovirus infections in human T cells.

Abstract
Effective targeting of vectors to tumor cells that have metastasized to multiple different tissue sites remains a major challenge for gene therapy. Tumor-specific cytotoxic T lymphocytes (CTLs) have been shown in animal models and in humans to be able to cross tissue barriers and traffic to tumor cells. However, their capacity to eliminate malignancy has been limited by tumor immune evasion strategies. We now use a model of Epstein-Barr virus-mediated malignancy to show that human CTLs themselves may be modified to release therapeutic vectors following engagement of their antigen-specific receptors and that these vectors will effectively transduce and destroy tumor targets. We generated EBV-specific CTLs that were transgenic for the adenoviral E1 gene under the control of the cell activation-dependent CD40 ligand (CD40L) promoter. Following transduction with E1-deficient adenoviral vectors, these CTLs produced infectious virus when exposed to HLA-matched EBV-expressing targets, but not on exposure to major histocompatibility complex (MHC)-mismatched or otherwise irrelevant cells. This approach provides a means of delivering oncolytic/therapeutic vectors not only to locally accessible macroscopic tumors as is presently the case, but also to disseminated metastatic disease, while avoiding the risks associated with systemic administration of large doses of adenoviral vectors.

Abstract
In the evolutionary battle between viruses and their hosts, viruses have armed themselves with weapons to defeat the host's attacks on infected cells. Various proteins encoded in the adenovirus (Ad) E3 transcription unit protect cells from killing mediated by cytotoxic T cells and death-inducing cytokines such as tumor necrosis factor (TNF), Fas ligand, and TNF-related apoptosis-inducing ligand (TRAIL). The viral protein E3-gp19 K blocks MHC class-I-restricted antigen presentation, which diminishes killing by cytotoxic T cells. The receptor internalization and degradation (RID) complex (formerly E3-10.4 K/14.5 K) stimulates the clearance from the cell surface and subsequent degradation of the receptors for Fas ligand and TRAIL, thereby preventing the action of these important immune mediators. RID also downmodulates the epidermal growth factor receptor (EGFR), although what role, if any, this function has in immune regulation is uncertain. In addition, RID antagonizes TNF-mediated apoptosis and inflammation through a mechanism that does not primarily involve receptor downregulation. E3-6.7 K functions together with RID in downregulating some TRAIL receptors and may block apoptosis independently of other E3 proteins. Furthermore, E3-14.7 K functions as a general inhibitor of TNF-mediated apoptosis and blocks TRAIL-induced apoptosis. Finally, after expending great effort to maintain cell viability during the early part of the virus replication cycle, Ads lyse the cell to allow efficient virus release and dissemination. To perform this task subgroup C Ads synthesize a protein late in infection named ADP (formerly E3-11.6 K) that is required for efficient virus release. This review focuses on recent experiments aimed at discovering the mechanism of action of these critically important viral proteins.

Abstract
Epithelial and endothelial cells expressing the primary Coxsackie virus B adenovirus (Ad) receptor (CAR) and integrin coreceptors are natural targets of human Ad infections. The fiber knob of species A, C, D, E and F Ad serotypes binds CAR by mimicking the CAR-homodimer interface, and the penton base containing arginine-glycine-aspartate (RGD) motifs binds with low affinity to alphav integrins inducing cell activation. Here, we generated seven different genetically modified Ad vectors with RGD sequences inserted into the HI loop of fiber knob. All mutants bound and infected CAR and alphav integrin-positive epithelial cells with equal efficiencies. However, the Ads containing two additional cysteines, both N and C terminals of the RGD sequence (RGD-4C), were uniquely capable of transducing CAR-less hematopoietic and nonhematopoietic human tumor cell lines and primary melanoma cells. Both binding and transduction of RGD-4C Ad were blocked by soluble RGD peptides. Flow cytometry of cell surface integrins and virus binding to CAR-less cells in the presence of function-blocking anti-integrin antibodies indicated that the alphavbeta5 integrin, but not alphavbeta3, alphaIIbbeta3 or beta1,alpha5 or alpha6-containing integrins served as a functional transduction receptor of the RGD-4C Ads. However, in cells with low levels of alphavbeta5 integrin, the function-blocking anti-alphavbeta5 antibodies were not effective, unlike soluble RGD peptides. Collectively, our data demonstrate that the alphavbeta5 integrin is a functional transduction receptor of RGD-4C Ads in the absence of CAR, and that additional RGD receptors are targets of these viruses. The RGD-4C vectors further extend the tropism of Ads towards potential human therapies.

Abstract
E3-6.7K is a small and hydrophobic membrane glycoprotein encoded by the E3 region of subgroup C adenovirus. Recently, E3-6.7K has been shown to be required for the downregulation of tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) receptors by the adenovirus E3/10.4K and E3/14.5K complex of proteins. We demonstrate here that E3-6.7K has additional protective roles, independent of other virus proteins. In transfected Jurkat T-cell lymphoma cells, E3-6.7K was found to maintain endoplasmic reticulum-Ca(2+) homeostasis and inhibit the induction of apoptosis by thapsigargin. The presence of E3-6.7K also lead to a reduction in the TNF-induced release of arachidonic acid from transfected U937 human histiocytic lymphoma cells. In addition, E3-6.7K protected cells against apoptosis induced through Fas, TNF receptor, and TRAIL receptors. Therefore, E3-6.7K confers a wide range of protective effects against both Ca(2+) flux-induced and death receptor-mediated apoptosis.

Abstract
Adenovirus (Ad) efficiently delivers its DNA genome into a variety of cells and tissues, provided that these cells express appropriate receptors, including the coxsackie-adenovirus receptor (CAR), which binds to the terminal knob domain of the viral capsid protein fiber. To render CAR-negative cells susceptible to Ad infection, we have produced a bispecific hybrid adapter protein consisting of the amino-terminal extracellular domain of the human CAR protein (CARex) and the Fc region of the human immunoglobulin G1 protein, comprising the hinge and the CH2 and CH3 regions. CARex-Fc was purified from COS7 cell supernatants and mixed with Ad particles, thus blocking Ad infection of CAR-positive but Fc receptor-negative cells. The functionality of the CARex domain was further confirmed by successful immunization of mice with CARex-Fc followed by selection of a monoclonal anti-human CAR antibody (E1-1), which blocked Ad infection of CAR-positive cells. When mixed with Ad expressing eGFP, CARex-Fc mediated an up to 250-fold increase of transgene expression in CAR-negative human monocytic cell lines expressing the high-affinity Fcgamma receptor I (CD64) but not in cells expressing the low-affinity Fcgamma receptor II (CD32) or III (CD16). These results open new perspectives for Ad-mediated cancer cell vaccination, including the treatment of acute myeloid leukemia.

Abstract
Adenovirus is a common respiratory pathogen which causes a broad range of distinct clinical syndromes and has recently received attention for its potential for in vivo gene delivery. Although adenovirus respiratory tract infection (ARTI) results in dose-dependent, local inflammation, the pathogenesis of this remains unclear. We hypothesized that alveolar macrophages (AMphi) rapidly internalize adenovirus following in vivo pulmonary administration and then initiate inflammatory signaling within the lung. To evaluate the role of AMphi in the induction of lung inflammation during ARTI in vivo, we directly assessed adenovirus uptake by murine AMphi and correlated uptake with the initiation of proinflammatory gene expression. Stimulation of cytokine (tumor necrosis factor alpha [TNF-alpha], interleukin-6 [IL-6], macrophage inflammatory protein-2 [MIP-2], and MIP-1alpha) expression in the lung was evaluated at the level of mRNA (by reverse transcription-PCR [RT-PCR]) and protein (by enzyme-linked immunosorbent assay) and by identification of cells expressing TNF-alpha and IL-6 mRNA in lung tissues (by in situ hybridization) and isolated lung lavage cells (by RT-PCR). Adenovirus, labeled with the fluorescent dye (Cy3), was rapidly and widely distributed on epithelial surfaces of airways and alveoli and was very rapidly ( approximately 1 min) localized within AMphi. At 30 min after infection AMphi but not airway epithelial or vascular endothelial cells expressed mRNA for TNF-alpha and IL-6, thus identifying AMphi as the cell source of initial cytokine signaling. IL-6, TNF-alpha, MIP-2, and MIP-1alpha levels progressively increased in bronchoalveolar lavage fluid after pulmonary adenovirus infection, and all were significantly elevated at 6 h (P < 0.05). To begin to define the molecular mechanism(s) by which adenovirus initiates the inflammatory signaling in macrophages, TNF-alpha expression from adenovirus-infected RAW264.7 macrophages was evaluated in vitro. TNF-alpha expression was readily detected in adenovirus-infected RAW cell supernatant with kinetics similar to AMphi during in vivo infection. Blockage of virus uptake at specific cellular sites, including internalization (by wortmannin), endosome acidification and/or lysis (by chloroquine) or by Ca(2+) chelation (by BAPTA) completely blocked TNF-alpha expression. In conclusion, results showed that during ARTI, (i) AMphi rapidly internalized adenovirus, (ii) expression of inflammatory mediators was initiated within AMphi and not airway epithelial or other cells, and (iii) the initiation of inflammatory signaling was linked to virion uptake by macrophages occurring at a point after vesicle acidification. These results have implications for our understanding of the role of the AMphi in the initiation of inflammation following adenovirus infection and adenovirus-mediated gene transfer to the lung.

Abstract
Hematopoietic cells are attractive targets for gene therapy. However, no satisfactory vectors are currently available. A major problem with the most commonly used adenovirus vectors, based on adenovirus type 2 (Ad2) or Ad5, is their low binding efficiency for hematopoietic cells. In this study we identify two adenovirus serotypes with high affinity for hematopoietic cells. The binding efficiency of prototype serotypes Ad4p, Ad11p, and Ad35p for different committed hematopoietic cell lines representing T cells (Jurkat), B cells (DG75), monocytes (U937-2), myeloblasts (K562), and granulocytes (HL-60) was evaluated and compared to that of Ad5v, the commonly used adenovirus vector, using flow cytometry. In contrast to Ad5v, which bound to less than 10% of the cells in all experiments, Ad11p and Ad35p showed high binding efficiency for all of the different hematopoietic cell lines. Ad4p bound to the lymphocytic cell lines to some extent but less well to the myelomonocytic cell lines. The abilities of the different serotypes to infect, replicate, and form complete infectious particles in the hematopoietic cell lines were also investigated by immunostaining, (35)S labeling of viral proteins, and titrations of cell lysates. Ad11p and Ad35p infected the highest proportion of cells, and Ad11p infected all of the cell lines investigated. The Ad11p hexon was expressed equally well in K562 and A549 cells. Jurkat cells also showed high levels of expression of Ad11p hexons, but the production of infectious particles was low. The binding properties of virions were correlated to their ability to infect and be expressed.

Abstract
Adenovirus can establish persistent infections which may reactivate and cause disease in immunocompromised hosts. Lymphocytes have been postulated to serve as a site of adenoviral persistence based upon the ability to isolate adenovirus from tonsils and to detect adenovirus DNA by Southern blot hybridization in peripheral blood mononuclear cells (PBMC). To test this hypothesis, a more sensitive and specific polymerase chain reaction (PCR) assay was developed to detect adenovirus DNA. Two sets of nested primers were designed to conserved sequences in the adenovirus E1A and hexon genes. The E1A and hexon primers amplified DNA from representative adenoviral serotypes in all six adenoviral groups (A-F). Both primers detected a single copy of the adenovirus type 2 genome but were less sensitive for the group B type 35. None of 33 PBMC specimens from healthy adults and only one of 40 pediatric samples was positive (at a low level) for adenovirus DNA by nested PCR assay. In comparison, PBMC from two children with fatal adenoviral infection were both strongly positive for adenovirus DNA. It is concluded that, in contrast to a previous study, PBMC are not a common site of persistent group C adenoviral infection. In addition, assay of PBMC by the adenovirus-specific PCR may help detect early invasive disease and warrants further evaluation.

Abstract
A major impediment to the effective use of adenovirus vectors for gene therapy is a lack of knowledge of how these vectors interact with diverse cell types in vivo. Adenovirus attachment to most human cell types is mediated by the fiber protein, which binds to an as yet unidentified cell receptor. In contrast to this, we report that adenovirus type 2 (Ad2) attachment to hematopoietic cells is facilitated by interaction of the penton base protein with members of the beta2 integrin family. Adenovirus particles were capable of binding to human monocytic cells, which lack fiber receptors, and virus binding could be blocked by a soluble penton base or by a function-blocking monoclonal antibody to integrin alphaMbeta2. To confirm the role of alphaMbeta2 integrins in Ad2 binding to hematopoietic cells, we analyzed virus attachment and gene delivery to CHO cells expressing recombinant beta2 integrins. alphaMbeta2-expressing CHO cells supported 3- to 5-fold-higher levels of Ad2 binding and 5- to 10-fold-larger amounts of gene delivery than did nontransfected CHO cells, indicating that alphaMbeta2 facilitates adenovirus attachment to and infection of hematopoietic cells. While beta2 integrins promote Ad2 attachment to hematopoietic cells, further studies demonstrated that alphav integrins were required for the next step in infection, virus internalization into cell endosomes. These studies reveal a novel pathway of Ad2 infection of hematopoietic cells mediated by distinct integrins which facilitate separate events in virus entry. They also suggest a possible strategy for selective adenovirus-mediated gene delivery to hematopoietic cells.

Abstract
To investigate determinants of host cell susceptibility to infection, cells partially resistant to infection were selected from the rare cells which remained adherent after infection of a culture of A549 cells with Ad2RAE, a mutant of adenovirus type 2 whose vertex capsomers lack an Arg-Gly-Asp (RGD) sequence which mediates binding of wild-type virus to integrins. Integrins promote the internalization of attached virions, whereas adsorption itself results from binding of the viral fibers to an unidentified cellular receptor. Following three rounds of selection, a persistently infected culture was established in which virus replication was detected in approximately 5% of the cells. Uninfected cells were readily cloned from the culture, indicating that at any particular time the majority of cells in the culture were uninfected. The resistance of one clone of uninfected cells to infection was correlated with a 10-fold reduction in the concentration of fiber receptors on these cells compared with the parental A549 cell line, indicating that efficiency of virus adsorption depends on the receptor concentration. Surprisingly, the rate at which host cells internalized RGD-negative virus also was strongly dependent on the fiber receptor concentration. While internalization of wild-type virus is promoted by the binding of integrins to the penton base RGD sequence, these results suggest that virus also can enter cells by an alternate pathway which requires binding of virions to multiple fiber receptors.

Abstract
An adenovirus culture-positive lymphoblastoid cell line was derived from a bone marrow transplant recipient with fatal B-cell lymphoproliferative disease and adenovirus pneumonia. At autopsy, focal areas of the lymphoma infiltrating the patient's lung were positive for adenovirus proteins by immunohistochemical staining. The Epstein-Barr virus-transformed B-cell line Mk, established from pleural fluid cells, contained adenovirus virions in both the nucleus and the cytoplasm by electron microscopy. The majority of Mk cells expressed adenovirus proteins and produced a high level of infectious adenovirus by plaque assay analysis. However, in contrast to the rapid cell death induced by adenovirus in other permissive cell lines, Mk was maintained stably in tissue culture for 6 months. These data indicate that adenoviral replication is not sufficient for cell lysis and confirm that adenovirus can cause persistent infection in human lymphoid cells in vivo.

Abstract
To evaluate the prevalence of adenovirus strains in human immunodeficiency virus (HIV)-positive patients and to investigate their possible role in the onset of diarrhea, a total of 103 stools from HIV-seropositive patients at various stages of infection and 200 stools from sex and age cross-matched control subjects were examined. Adenovirus prevalence was measured by ELISA as well as conventional and rapid cell culture techniques. Results were compared between patients suffering from diarrhea and those without diarrhea. Adenovirus prevalence was statistically greater in HIV-seropositive cases than controls (8.7%, 2.5%, respectively). No significant difference was found between HIV-positive patients with diarrhea and those without gastrointestinal complications (P > 0.05). However, a significant difference in adenovirus prevalence was found between HIV-positive patients with diarrhea and control subjects with diarrhea (P = 0.02). Although viral prevalence varied with the different stages of HIV infection, differences were not statistically significant. In conclusion, although current opinion considers adenoviruses to be no more than opportunistic pathogens, the results of this large-scale study do not exclude a potential reactivation of latent adenovirus in HIV infection and suggest that further effort should be directed to elucidating such a mechanism if it exists as well as investigating the specific role of certain adenovirus serotypes in provoking diarrhea during later stages of HIV infection.

Abstract
Understanding the pathogenesis of viral myocarditis is linked to the availability of sensitive assays to detect viruses in clinical material. Recent advances in molecular techniques permit direct detection of viral-specific nucleic acid in tissue samples. This report describes a protocol for DNA extraction and amplification of adenovirus genome from formalin-fixed, paraffin-embedded human tissues that detects as little as 10 copies of viral genome in a background of 0.5 micrograms of human DNA. This sensitive assay permitted the examination of archived tissues to establish a retrospective diagnosis of adenoviral myocarditis in two pediatric patients.

Abstract
Adenovirus infection of human monocyte hybridoma cell lines and the fusion partner U937 was investigated. Adenovirus adsorbed poorly to these cells as well as primary human alveolar macrophages. The virus-binding experiments showed a 100-fold reduction in apparent viral binding to these cells compared to the permissive HeLa cells. Adsorption of adenovirus to these cells could be enhanced by preincubation of adenovirus with its antiserum. Following entry into the cells amplification of adenovirus DNA was detected starting at 2 days postinfection but few mature virus particles were produced. The infected cultures survived the infection and continued to grow for more than a year. In these chronically infected cultures, linear adenovirus DNA persisted up to 200 copies per cell and a small amount of mature virus was produced. Infectious center assay and cell cloning experiments showed that the majority of the cells in the chronically infected cultures harbor adenovirus genome. These results indicate that restriction of replication of human adenovirus type 5 at the late phase results in persistent infection of U937 and the human monocyte hybridoma cell lines.

Abstract
The 41 distinct antigenic types of adenoviruses (Ads) are responsible for a broad spectrum of diseases in humans. We have developed an enzyme-linked immunosorbent assay (ELISA) using adenovirus (Ad) infected MRC-5 cells for detecting IgG and IgM antibodies to Ads. Using the ELISA, we detected IgG antibodies in 100% (20/20) of sera from normal adults (geometric mean titer, GMT = 1840.8, range = 40-20,480) and IgM antibodies in 3 of 20 sera (15%) with a GMT of 25.1. Our indirect immunofluorescence (IF) technique also detected IgG antibodies in 100% of these sera (GMT = 248.3, range = 40-5,120) and IgM antibodies in the 3 samples reactive in ELISA (GMT = 20.0, range = less than 5-40). In contrast, the complement fixation (CF) test detected antibodies to Ads in only 65% (13/20) of these sera (GMT = 10.9, range = less than 4-32). Moreover, IgG and IgM responses could not be distinguished using CF. Thus the sensitivity of these three techniques is greatest for ELISA. Additionally, a study of sequential sera from 3 patients with acute Ad infection disclosed seroconversion using all three methods. Both the ELISA and IF techniques permit the detection of transition from IgM to IgG, whereas CF only detects conversion from seronegativity to seropositivity. Finally, preliminary data suggest that the IgM response as measured by ELISA is specific for subgroups or types of Ad. This newly devised ELISA may be useful for detecting Ad infections.

Abstract
Human adenoviruses (e.g., Ad2, Ad5) establish chronic infections in human lymphoid-derived cell lines, including Raji and Jijoye (R.E. Wallace, 1969, Proc. Soc. Exp. Biol. Med. 130, 702-710; N. Faucon, G. Ogier, and Y. Chardonnet, 1982, J. Natl. Cancer Inst. 69, 1215-1220); however, the mechanisms by which chronic infections are established and maintained are not understood. When Raji or MOLT-3 cell cultures were infected with Ad2 at high multiplicity, these cell lines continued to grow exponentially and produced only small amounts of infectious virus. Virus-specific antigens, including the DNA-binding protein and hexon, were expressed in only 5% of the Ad2-inoculated cultures. All Raji and MOLT-3 cells were found to have adenovirus receptors, but the Ad2 virions that adsorbed to most Raji cells were sequestered in caps, suggesting that most cells fail to internalize adsorbed Ad2. Cell synchronization experiments showed a correlation between the proportion of cells that became productively infected and the proportion of cells in mitosis at the time of infection. In contrast, primary blood lymphocytes had few, if any, Ad2 receptors and were not productively infected by Ad2.

Abstract
The capacity of freshly explanted human peripheral blood lymphocytes (PBL) to support the replication of human adenovirus type 2 (Ad2) was investigated. Unlike other types of human cells, PBL were found to be highly nonpermissive. Ad2 adsorbed 30 to 40% of both T and non-T cells. Virus uncoating was very slow and inefficient, resulting in a 40-fold reduction compared with HEp-2 cells. On a population basis, viral DNA synthesis was reduced 460-fold and infectious virus production was reduced 10(6)-fold. Only 0.35% of PBL produced infectious centers, yielding 0.8 PFU per infected cell. Phytohemagglutinin stimulation increased DNA synthesis 23-fold, infectious centers 11-fold, and virus yield 14-fold. We conclude that resting human PBL are highly nonpermissive to Ad2 infection and that phytohemagglutinin can only marginally lift this nonpermissiveness.

Abstract
Human peripheral blood lymphocytes from healthy adults, cord blood lymphocytes, and lymphoblastoid cell lines were screened by hybridization for the presence of group C adenovirus DNA sequences. In 13 of 17 peripheral blood lymphocyte samples from adults, 1 of 10 cord blood samples, and seven of seven lymphoblastoid cell lines tested, results were positive for Group C adenovirus DNA (adenovirus 1 [Ad1], Ad2, Ad5, or Ad6). About 1 to 2% of the lymphocytes carried 50 to 100 viral genome copies per positive cell, as estimated by in situ hybridization. Infectious virus representing all members of group C were recovered, but cultivation in the presence of adenovirus antibody did not cure the cells of free viral genomes. Viral DNA was found in B, T, and N cells but only in 1 of 10 cord blood samples. The results suggest that group C adenovirus infections in childhood result in the persistence of the viral genome in circulating lymphocytes.

Abstract
Exposing human lymphoid cell lines to uncloned or recently cloned group B coxsackieviruses results in the frequent establishment of chronically infected cultures. Persistence is maintained by a carrier culture mechanism involving virus spread through the medium and replication among a minority of cells at any given time. These studies provide a model for persistence by highly cytocidal viruses.
