Abstract
BACKGROUND Human polyomaviruses contribute to human oncogenesis through persistent infections, but currently there is no effective preventive measure against the malignancies caused by this virus. Therefore, the development of a safe and effective vaccine against HPyV is of high priority. METHODS First, the proteomes of 2 polyomavirus species (HPyV6 and HPyV7) were downloaded from the NCBI database for the selection of the target proteins. The epitope identification process focused on selecting proteins that were crucial, associated with virulence, present on the surface, antigenic, non-toxic, and non-homologous with the human proteome. Then, the immunoinformatic methods were used to identify cytotoxic T-lymphocyte (CTL), helper T-lymphocyte (HTL), and B-cell epitopes from the target antigens, which could be used to create epitope-based vaccine. The physicochemical features of the designed vaccine were predicted through various online servers. The binding pattern and stability between the vaccine candidate and Toll-like receptors were analyzed through molecular docking and molecular dynamics (MD) simulation, while the immunogenicity of the designed vaccines was assessed using immune simulation. RESULTS Online tools were utilized to forecast the most optimal epitope from the immunogenic targets, including LTAg, VP1, and VP1 antigens of HPyV6 and HPyV7. A multi-epitope vaccine was developed by combining 10 CTL, 7 HTL, and 6 LBL epitopes with suitable linkers and adjuvant. The vaccine displayed 98.35% of the world's population coverage. The 3D model of the vaccine structure revealed that the majority of residues (87.7%) were located in favored regions of the Ramachandran plot. The evaluation of molecular docking and MD simulation revealed that the constructed vaccine exhibits a strong binding (-1414.0 kcal/mol) towards the host's TLR4. Moreover, the vaccine-TLR complexes remained stable throughout the dynamic conditions present in the natural environment. The immune simulation results demonstrated that the vaccine design had the capacity to elicit robust immune responses in the host. CONCLUSION The multi-parametric analysis revealed that the designed vaccine is capable of inducing sustained immunity against the selected polyomaviruses, although further in-vivo investigations are needed to verify its effectiveness.

Abstract
Background Bladder cancer is a challenging public health concern in South of Iran because of its high prevalence and the related medical expenses. Although the exact etiology of bladder cancer remains unknown, given the cell transforming ability and oncogenic potential of the members of Polyomaviridae families, this study was conducted to evaluate the magnitude of BK polyomavirus (BKPyV) and John Cunningham polyomavirus (JCPyV) among patients with bladder cancer residents in the northern shores of the Persian Gulf, South of Iran. Methods Totally 211 patients with bladder cancer were enrolled in this study. Bladder biopsy samples of these patients and patients with interstitial cystitis as well as autoptic samples of healthy bladder were tested for detection of BKPyV and JCPyV by semi-nested PCR–RFLP followed by sequencing. Results BKPyV and JCPyV were detected in 1.7% and 6.1% of bladder cancer samples, respectively. These samples were infected with JCPyV genotypes 2, 3 and 6 and BKPyV genotypes I and IV. BKPyV and JCPyV coinfection was detected in 2 samples. Moreover, one of the healthy bladder samples was positive for BKPyV, and one of the interstitial cystitis samples was positive for JCPyV. Although the majority of infected patients were in the age group 70–79 years, male, residents in Tangestan, stage Ta–T1, and low-grade and high-grade papillary urothelial carcinoma, the prevalence of BKPyV and JCPyV among patients with bladder cancer was not statistically associated with age, gender, place of residency, and stage and grade of the tumor. Conclusion Despite identifying BKPyV and JCPyV in a number of bladder cancer biopsy specimens and the high prevalence of bladder cancer among people resident in South of Iran, it is suggested that these viruses are unlikely to be effective causative factors in bladder carcinogenesis in this region. Therefore, environmental risk factors and genetic backgrounds may have a more prominent role than human polyomaviruses in the development of bladder cancer in South of Iran.

Abstract
Human polyomaviruses are relatively common in the general population. Polyomaviruses maintain a persistent infection after initial infection in childhood, acting as an opportunistic pathogen in immunocompromised populations and their association has been linked to carcinogenesis. A comprehensive understanding of the underlying molecular mechanisms of carcinogenesis in consequence of polyomavirus infection remains elusive. However, the critical role of viral miRNAs and their potential targets in modifying the transcriptome profile of the host remains largely unknown. Polyomavirus-derived miRNAs have the potential to play a substantial role in carcinogenesis. Employing computational approaches, putative viral miRNAs along with their target genes have been predicted and possible roles of the targeted genes in many significant biological processes have been obtained. Polyomaviruses have been observed to target intracellular signal transduction pathways through miRNA-mediated epigenetic regulation, which may contribute to cancer development. In addition, BKPyV-infected human renal cell microarray data was coupled with predicted target genes and analysis of the downregulated genes indicated that viruses target multiple signaling pathways (e.g. MAPK signaling pathway, PI3K-Akt signaling pathway, PPAR signaling pathway) in the host as well as turning off several tumor suppression genes (e.g. FGGY, EPHX2, CACNA2D3, CDH16) through miRNA-induced mechanisms, assuring cell transformation. This study provides a conceptual framework for the underlying molecular mechanisms involved in the course of carcinogenesis upon polyomavirus infection.

Abstract
BACKGROUND Washington University polyomavirus (WUPyV) is a novel human polyomavirus detected in childwith acute respiratory infection in 2007. However, the relationship between WUPyV and respiratory diseases has yet to be established for lacking of a suitable in vitro culture system. METHODS To isolate WUPyV with human airway epithelial (HAE) cells, the positive samples were incubated in HAE, and then the nucleic acid, VP1 protein and virions were detected using real-time PCR, immunofluorescence and electron microscopy respectively. RESULTS The result showed that WUPyV could replicate effectively in HAE cells and virions with typical polyomavirus characteristics could be observed. Additionally, the entire genome sequence of the isolated strain (BJ0771) was obtained and phylogenetic analysis indicated that BJ0771 belongs to gene cluster I. CONCLUSIONS Our findings demonstrated clinical WUPyV strain was successfully isolated for the first time in the world and this will help unravel the etiology and pathogenic mechanisms of WUPyV in respiratory infection diseases.

Abstract
The human DNA damage response (DDR) is a complex signaling network constituting many factors responsible for the preservation of genomic integrity. Human polyomaviruses (HPyVs) are able to harness the DDR machinery during their infectious cycle by expressing an array of tumor (T) antigens. These molecular interactions between human polyomavirus T antigens and the DDR create conditions that promote viral replication at the expense of host genomic stability to cause disease as well as carcinogenesis in the cases of the Merkel cell polyomavirus and BK polyomavirus. This review focuses on the six HPyVs with disease association, emphasizing strain-dependent differences in their selective manipulation of the DDR. Appreciation of the HPyV-DDR interface at a molecular scale is conducive to the development of novel therapeutic approaches.

Abstract
Alternative indicators may be more suitable than thermotolerant coliform bacteria to assess enteric virus pollution in environmental waters and their removal from wastewaters. In this study, F-specific RNA bacteriophages (F-RNAPh) showed to be potential viral indicators of fecal contamination when they were quantified from domestic and food-industrial effluents containing human, chicken, swine or bovine wastes. In addition, they showed to be resistant to the primary and secondary treatments of the wastewater treatment plants. The viable F-RNAPh count showed correlation with viable thermotolerant coliforms but also with human polyomaviruses (HPyV) quantified by a new molecular method. In domestic effluents, F-RNAPh and HPyV indicators significantly correlated with a human viral pathogen, norovirus, while the bacterial indicator did not, being then better predictors of the behavior of enteric pathogenic viruses. In addition, we assessed human, bovine and fowl microbial source tracking markers, based on the molecular detections of human polyomavirus, bovine polyomavirus, and fowl adenovirus, respectively. The techniques implemented extend the range of viruses detected, since they target different viral types simultaneously. These markers could be applied when multiple source pollution is suspected, contributing to making decisions on public health interventions.

Abstract
BACKGROUND Human polyomaviruses (HPyVs) asymptomatically infect the human population during childhood and establish latency in the host. Viral reactivation and urinary excretion can occur when the immune system is impaired. Exposure to particulate air pollution, including the PM10/PM2.5 components, is a public health problem and has been linked to several disorders. Studies assessing the relationship between PM10/PM2.5 exposure and viral replication are lacking. OBJECTIVES To investigate the relationship between HPyVs viruria and PM10/PM2.5 exposures. METHODS Individual environmental exposure was assessed in 50 healthy adult volunteers using a chemical transport model (CTM) with a municipality resolution for daily PM10 and monitoring stations data for daily PM2.5 exposures. For each subject, a urine sample was collected, and HPyVs (JCPyV, BKPyV, MCPyV, HPyV6, HPyV7 and HPyV9) loads were determined. Zero-inflated negative binomial (ZINB) regression was used to model the count data, as it contained excessive zeros. Covariates were chosen by stepwise selection. RESULTS HPyVs DNA was detected in 54% (median:87.6*105 copies/ml) of the urine samples. JCPyV was the prevalent (48%, (median viral load:126*105 copies/ml). Considering the load of the most frequently measured HPyVs, JCPyV, in the count-part of the ZINB model, every unitary in PM measured 2 days before urine collection (PM Day -2) was associated with an increase in JCPyV load (PM10: +4.0%, p-value = 0.002; PM2.5: +3.6%, p-value = 0.005). In the zero-part, the significant predictor was the PM10 measured 5 days before urine collection (+3%, p-value = 0.03). CONCLUSIONS The environmental levels of PM10/PM2.5 increase the JCPyV viruria. Our findings emphasize the need for studies assessing the influence of air pollution exposure on the risk of viral reactivation.

Abstract
BACKGROUND/AIM The etiopathogenesis of mycosis fungoides and Sézary syndrome remains obscure. Different viruses have been proposed to have a role in the etiopathogenesis of cutaneous T-cell lymphomas (CTCL). In the present study, the presence of five recently discovered human polyomaviruses 6 (HPyV6), human polyomaviruses 7 (HPyV7), human polyomaviruses 9 (HPyV9), human polyomaviruses 12 (HPyV12), and Malawi polyomavirus (MWPyV), have been analyzed in 55 CTCL in order to confirm the skin tropism and the possible pathological association of these new polyomaviruses. MATERIALS AND METHODS Human polyomaviruses DNA were amplified from skin lesions were recovered from a total of 55 patients (32 males and 23 females, average age 63±15 years) affected by CTCL. RESULTS When assayed for the presence of 5 different HPyVs, (HPyV6, HPyV7, HPyV9, MWPyV, and HPyV12) HPyV9, HPyV10 and HPyV12 DNA sequences were not found in any skin specimens. HPyV6 and 7 DNA was detected in 1/55 (1.8%) of skin specimens. CONCLUSION The low-level presence of HPyV6 and HPyV7 DNA, and lack of detection of polyomaviruses HPyV9, MWPyV and HPyV12 in our series do not support a significant role of these HPyVs subtypes in the etiopathogenesis of skin cancers.

Abstract
Human papillomaviruses (HPVs) are an acknowledged cause of a subset of oropharyngeal cancers, especially of tonsillar cancer. Similar to HPV, some human polyomaviruses (HPyVs), such as Merkel cell polyomavirus (MCPyV), have an oncogenic potential. Recently, several novel HPyVs have been discovered. The aim of our study was to determine viral DNA prevalence and viral DNA load of 13 different HPyVs in benign and malignant tonsillar tissue and to compare the data with those found for HPV. A total of 78 biopsies of palatine tonsils with a histologic diagnosis of non-malignant disease (chronic tonsillitis, tonsillar hyperplasia, n = 40) or tonsillar squamous cell carcinoma (n = 38) were included in the study. HPyV DNA prevalence and viral load were determined by virus-specific quantitative real-time PCRs. JCPyV (1/40, 2.5%) and WUPyV (3/40, 7.5%) were only found in non-malignant tonsillar tissue. HPyV7 and HPyV10 were only detected in one (2.6%) and seven (18.4%) of the 38 cancer biopsies, respectively. Both MCPyV (8/38, 21.1 vs. 4/40, 10.0%) and HPyV6 (2/38, 5.3 vs. 1/40, 2.5%) were found more frequently in cancer samples than in non-malignant tissue, but the differences were not significant. BKPyV, KIPyV, TSPyV, HPyV9, STLPyV, HPyV12 and NJPyV were not discovered in any of the samples. HPyV loads found in HPyV DNA-positive biopsies were very low with no difference between non-malignant and malignant samples (median load <0.0001 HPyV DNA copies per beta-globin gene copy, respectively). In contrast to HPyV, high-risk HPV types (HPV16/HPV18) were found significantly more frequently in tonsillar cancers than in non-malignant tonsillar tissue (17/38, 44.7 vs. 2/40, 5.0%, p < 0.001). Furthermore, high-risk HPV DNA loads were significantly higher in the cancer compared to the non-malignant samples (median load 11.861 vs. 7 × 10-6 HPV DNA copies per beta-globin gene copy, p = 0.012). While both HPV and HPyV may persist in tonsillar tissue, our data on HPyV DNA prevalence and load do not support a role of HPyV in tonsillar carcinogenesis, neither alone nor as co-infecting agents of HPV.

Abstract
Background Studies of human polyomavirus (HPyV) infection and lung cancer are limited and those regarding the association of human papillomavirus (HPV) infection and lung cancer have produced inconsistent results. Methods We conducted a nested case–control study to assess the association between incident lung cancer of various histologies and evidence of prior infection with HPyVs and HPVs. We selected serum from 183 cases and 217 frequency matched controls from the Yunnan Tin Miner’s Cohort study, which was designed to identify biomarkers for early detection of lung cancer. Using multiplex liquid bead microarray (LBMA) antibody assays, we tested for antibodies to the VP1 structural protein and small T antigen (ST-Ag) of Merkel cell, KI, and WU HPyVs. We also tested for antibodies against HPV L1 structural proteins (high-risk types 16, 18, 31, 33, 52, and 58 and low-risk types 6 and 11) and E6 and E7 oncoproteins (high risk types 16 and 18). Measures of antibody reactivity were log transformed and analyzed using logistic regression. Results We found no association between KIV, WUV, and MCV antibody levels and incident lung cancer (P-corrected for multiple comparisons >0.10 for all trend tests). We also found no association with HPV-16, 18, 31, 33, 52, and 58 seropositivity (P-corrected for multiple comparisons >0.05 for all). Conclusions Future studies of infectious etiologies of lung cancer should look beyond HPyVs and HPVs as candidate infectious agents.

Abstract
Waterborne exposure to human viruses is possible through contact with contaminated water environments and can result in infections associated with a wide range of illnesses, including gastrointestinal, respiratory, ear, ocular, and skin infections. Recently, the occurrence in water environments of two groups of human viruses-both known with oncogenic potential, human polyomaviruses (HPyVs) and papillomaviruses (HPVs)-has been reported worldwide. These viruses, responsible for highly prevalent infections worldwide, have recently been proposed as potentially emerging waterborne pathogens. The objective of the present study was to examine the occurrence of HPyVs and HPVs in surface waters, by monitoring two rivers in Northwestern Italy, by nested PCR assays and sequencing. HPyVs (JC, BK, and Merkel cell polyomavirus) were detected in 10/25 (40%) samples. HPVs (HPV8, 17, 21, 25, 32, 80, 99, 105, and putative new HPVs) were identified in 14/25 (56%) river samples. The number of HPV DNA copies in waters was measured by quantitative real-time PCR. To our knowledge, this is the first detection and quantification of HPVs in surface waters. The possibility that HPyVs and HPVs can be transmitted by the waterborne route deserves to be explored in future studies.

Abstract
BACKGROUND Trichodysplasia spinulosa-associated polyomavirus (TSV) was identified in, and shown to be the probable cause of, trichodysplasia spinulosa, a rare skin disease. To date, serological analyses have revealed that TSV infection is common among adults in the general population of Europe and Australia. However, there have been no reports of TSV in Asia. OBJECTIVE To study the prevalence of TSV infection in Japan. STUDY DESIGN TSV-VP1 expressed in a recombinant baculovirus expression system in an insect cell line, Tn5, self-assembled into virus-like particles. Overall, 1000 serum samples were examined by enzyme-linked immunosorbent assays using virus-like particles of TSV as antigen. Participants ranged in age from 0 to 94 years. RESULTS Overall, 629 of 1000 serum samples (62.9%) were positive for anti-TSV antibodies. The seropositive rate increased with age and the seroprevalence of TSV significantly increased from 17.1% (25/146) in children aged from 0 to 4 years to 78.7% (472/600) in adults aged over 20 years (odds ratio = 0.056, 95% confidence interval = 0.035-0.900, P = 0.000, Chi-squared test). TSV seropositivity was not different between sera obtained in 1980 and 2012, and was not associated with sex. Competitive assay demonstrated that TSV antibodies did not cross-react with BK virus or Merkel cell polyomavirus. CONCLUSIONS These results provide evidence that TSV circulates widely in the Japanese population, with primary exposure occurring mainly at early childhood, similar to that previously reported in other countries.

Abstract
The rare autosomal dominant condition Birt-Hogg-Dubé syndrome (BHD) is attributed to mutations on chromosome 17 in the folliculin (FLCN) gene, but not always diagnosed due to lack of, or a variety of symptoms such as fibrofolliculomas, lung cystic lesions, spontaneous pneumothorax and renal cancer. We hypothesized that the lack of or variability in symptoms could be due to BHD patients potentially being abnormally susceptible to infections with human papillomavirus (HPV) or human polyomavirus (HPyV), which can be associated with skin lesions or latency in the kidneys. Seven fibrofolliculoma skin lesions, one renal cancer and one lung cyst from nine patients with BHD treated at the Karolinska University Hospital were therefore analyzed for cutaneous and mucosal HPV types and 10 HPyVs by bead based multiplex assays or by PCR. All samples were negative for viral DNA. In conclusion, the data suggest that HPV and HPyVs do not contribute to BHD pathology.

Abstract
Discharge of inadequately treated human wastewater into surface waters used for recreation, drinking water, irrigation and shellfish cultivation may present a public health hazard due to the potential shedding of high concentrations of pathogenic viruses from the human gastrointestinal tract. Human adenovirus (HAdV) and human polyomavirus (HPyV) are ubiquitous in humans and have excellent survival characteristics in the environment, so are potential candidates for indicators of human sewage contamination. Using qPCR assays, the prevalence and quantity of HAdV and HPyV JC and BK were determined in influent and effluent wastewater and receiving waters (river, urban stream, estuarine), then compared with norovirus (NoV) presence, a significant human pathogen which is not necessarily ubiquitously excreted into the environment. HAdV and HPyV were frequently detected in high concentrations in wastewater and wastewater-contaminated waters confirming their use as potential indicators for the presence of human sewage. Overall, there was a correlation between the presence of HAdV and HPyV with NoV but there were some notable exceptions including the higher frequency of NoV compared to HAdV and HPyV in estuarine waters impacted by wastewater overflows. We found that HAdV and HPyV detection by qPCR was a suitable tool for evaluating water quality and that their detection can aid in determining pollution sources, thus providing useful information for health risk assessments.

Abstract
For almost 40 years, polyomavirus JC and BK were the only known human polyomaviruses but in the last 7 years, increased interest and innovative molecular screening techniques have led to the identification of 10 previously unknown polyomaviruses in humans. Two of these, Merkel cell polyomavirus and Trichodysplasia spinulosa polyomavirus, have also been found to cause disease in immunocompromised patients. Seroprevalence studies indicate that human polyomaviruses are transmitted independently of one another in humans and carry different risks of exposure and reexposure throughout life. The potential coexistence of 12 or more different polyomavirus species in the same host and possibly even in the same organ raises the question of potential interactions. Careful review of polyomavirus biology may facilitate new discoveries concerning these formerly underestimated viral agents and their influence on human health.
