The family contains seven genera: DELTARETROVIRUS; LENTIVIRUS; RETROVIRUSES TYPE B, MAMMALIAN; ALPHARETROVIRUS; GAMMARETROVIRUS; RETROVIRUSES TYPE D; and SPUMAVIRUS. A key feature of retrovirus biology is the synthesis of a DNA copy of the genome which is integrated into cellular DNA. After integration it is sometimes not expressed but maintained in a latent state (PROVIRUSES).
Human immunodeficiency virus. A non-taxonomic and historical term referring to any of two species, specifically HIV-1 and/or HIV-2. Prior to 1986, this was called human T-lymphotropic virus type III/lymphadenopathy-associated virus (HTLV-III/LAV). From 1986-1990, it was an official species called HIV. Since 1991, HIV was no longer considered an official species name; the two species were designated HIV-1 and HIV-2.

A possible contributory role of BK virus infection in neuroblastoma development. (1/481)

The tumor suppressor protein p53 is aberrantly localized to the cytoplasm of neuroblastoma cells, compromising the suppressor function of this protein. Such tumors are experimentally induced in transgenic mice expressing the large tumor (T) antigen of polyomaviruses. The oncogenic mechanisms of T antigen include complex formation with, and inactivation of, the tumor suppressor protein p53. Samples from 18 human neuroblastomas and five normal human adrenal glands were examined. BK virus DNA was detected in all neuroblastomas and none of five normal adrenal glands by PCR. Using DNA in situ hybridization, polyomaviral DNA was found in the tumor cells of 17 of 18 neuroblastomas, but in none of five adrenal medullas. Expression of the large T antigen was detected in the tumor cells of 16 of 18 neuroblastomas, but in none of the five adrenal medullas. By double immunostaining BK virus T antigen and p53 was colocalized to the cytoplasm of the tumor cells. Immunoprecipitation revealed binding between the two proteins. The presence and expression of BK virus in neuroblastomas, but not in normal adrenal medulla, and colocalization and binding to p53, suggest that this virus may play a contributory role in the development of this neoplasm.  (+info)

Concerted expression of BK virus large T- and small t-antigens strongly enhances oestrogen receptor-mediated transcription. (2/481)

Previous studies have shown that the human polyomavirus BK (BKV) genome contains an oestrogen response element (ERE). This isolated element binds its cognate receptor in vitro and can mediate 17beta-oestradiol-induced gene expression when linked to a heterologous promoter. The roles of the ERE- and the AP-1-binding sites in oestrogen receptor-directed transcription from the complete BKV promoter/enhancer (Dunlop strain) have been examined and the effects of the general co-activator CBP and large T- and small t-antigens on oestrogen receptor-mediated transcription have been investigated. A constitutive activated oestrogen receptor stimulated BKV promoter activity in HeLa cells. Mutations in either the ERE- or the AP-1-binding sites did not impair oestrogen receptor-induced activation of the BKV Dunlop promoter, while mutations in both binding motifs almost completely abolished oestrogen receptor-induced transcription. Simultaneous expression of large T- and small t-antigens strongly activated oestrogen receptor-mediated transcription. When expressed separately, only large T-antigen moderately stimulated oestrogen receptor-mediated transcription. The stimulatory effect of large T-antigen on the activity of the oestrogen receptor is probably indirect because no physical interaction between the two proteins was detected in a two-hybrid assay. Large T-antigen abrogated the synergistic effect on transcription between this nuclear receptor and the general co-activator CBP. The findings that the BKV early proteins amplify oestrogen receptor-mediated transcription may have important biological implications in individuals with raised oestrogen concentrations.  (+info)

Morphological, histochemical, immunohistochemical, and ultrastructural characterization of tumors and dysplastic and non-neoplastic lesions arising in BK virus/tat transgenic mice. (3/481)

To study the role in AIDS pathogenesis of the human immunodeficiency virus type 1 (HIV-1) Tat protein, a transactivator of viral and cellular genes, we generated transgenic mice with a recombinant DNA containing BK virus (BKV) early region and the HIV-1 tat gene, directed by its own promoter-enhancer. DNA hybridization revealed that the transgene is stably maintained in all organs of transgenic mice as a tandem insertion in a number of copies ranging from 5 to 20 per cell. In addition, tat and BKV RNA were expressed in all tissues. Transgenic mice developed three types of lesions: 1) tumors, 2) hyperplastic and dysplastic lesions, and 3) non-neoplastic lesions. Tumors of different histotypes, such as lymphomas, adenocarcinomas of skin glands, leiomyosarcomas, skin squamous cell carcinomas, hepatomas, hepatocarcinomas, and cavernous liver hemangiomas, developed in 29% of transgenic animals. The majority of tumors were malignant, invasive, and producing metastases. Conversely, tumors of only two histotypes (lymphomas and adenocarcinomas of skin glands) appeared in control mice. Hyperplastic and dysplastic lesions were more frequent in transgenic than in control mice and involved the skin or its adnexes, the liver and the rectum, indicating multiple targets for the activity of the transgene. Pyelonephritis, frequently complicated with hydronephrosis, inflammatory eye lesions, and amyloid depositions represented the most frequent non-neoplastic lesions detected in transgenic mice. Many of the pathological findings observed in this animal model are comparable to similar lesions appearing in AIDS patients, suggesting a relevant role for Tat in the pathogenesis of such lesions during the course of AIDS.  (+info)

BK and JC viruses in patients with systemic lupus erythematosus: prevalent and persistent BK viruria, sequence stability of the viral regulatory regions, and nondetectable viremia. (4/481)

A role for polyomaviruses in the pathogenesis of systemic lupus erythematosus (SLE) has been suggested. BK virus (BKV) and JC virus (JCV) were demonstrated in single urine specimens from 7 (16%) of 44 and 5 (11%) of 44 patients with SLE and 0/88 and 18 (21%) of 88 matched healthy controls, respectively. During a 1-year follow-up study, episodes of polyomaviruria were detected in 16 (80%) of 20 patients, BKV in 13, and JCV in 3 patients. A group of 12 (60%) of 20 patients demonstrated persistent or recurrent polyomaviruria, BKV viruria (n=9), or JCV viruria (n=3) in 180 (70%) of 256 specimens. Polyomaviruria was not significantly associated with immunosuppressive therapy. The BKV and JCV isolates revealed predominantly stable archetypal regulatory regions over 3 years, indicating viral persistence rather than reinfection as a cause for urinary shedding. The demonstration of nondetectable viremia and stable archetypal BKV and JCV noncoding control regions during persistent viruria argue against the urinary tract as a focus for the creation of rearranged regulatory region variants.  (+info)

JC and BK virus sequences are not detectable in leukaemic samples from children with common acute lymphoblastic leukaemia. (5/481)

Epidemiological evidence suggests that childhood leukaemia, and possibly common acute lymphoblastic leukaemia in particular, may have an infectious aetiology. Smith (1997 J Immunother 20: 89-100) recently suggested that the critical infectious event occurs during pregnancy, and identified the polyoma virus JC as a candidate agent. In the present study we investigated whether genomes from the JC virus, and closely related BK virus, could be detected in leukaemic cells. No positive results were obtained suggesting that JC virus is unlikely to play a direct role in leukaemogenesis.  (+info)

Comparison of antibody titers determined by hemagglutination inhibition and enzyme immunoassay for JC virus and BK virus. (6/481)

A comparison of antibody titers to JC virus (JCV) or BK virus (BKV) was made by hemagglutination inhibition (HI) and enzyme immunoassay (EIA) with 114 human plasma samples. Antibody titers to JCV or BKV determined by HI were lower than those determined by EIA. Nevertheless, as HI titers increased so did EIA titers. When antibody data were compared by the Spearman rank correlation test, highly significant correlations were found between HI and EIA titers. Results obtained by plotting EIA antibody titers for JCV against those for BKV generally showed a reciprocal relationship, i.e., samples with high antibody titers to JCV had lower antibody titers to BKV and vice versa. Some samples, however, had antibody titers to both viruses. Of the samples tested, 25.4% (25 of 114) had HI and EIA antibody titers to JCV and BKV which were identical or closely related. This is not the scenario one would expect for cross-reactive epitopes shared by the two viruses, but one suggesting that these samples were from individuals who had experienced infections by both viruses. Adsorption with concentrated JCV or BKV antigen of sera with high antibody titers to both JCV and BKV and testing by JCV and BKV EIA gave results which support this conclusion. Although 52.6% (51 of 97) of the samples from the Japanese population tested had very high antibody titers (>/=40,960) to either JCV or BKV, none of the samples were found by a dot blot immunoassay to have antibodies which cross-reacted with simian virus 40. The results from this study, in agreement with those of others, suggest that humans infected by JCV or BKV produce antibodies to species-specific epitopes on their VP1 capsid protein, which is associated with hemagglutination and cellular binding.  (+info)

Polyomaviruria in renal transplant patients is not correlated to the cold ischemia period or to rejection episodes. (7/481)

Polyomaviruria was observed in one-third of all renal transplant patients, irrespective of whether their renal grafts came from a living or cadaver donor, and was not correlated to graft rejection episodes. This suggests that the renal graft ischemia period is not the major cause of polyomavirus reactivation and that reactivation of polyomavirus is not a dominant cause of graft rejection.  (+info)

Documenting the epidemiologic patterns of polyomaviruses in human populations by studying their presence in urban sewage. (8/481)

This is the first description, to our knowledge, of the distribution of human polyomavirus and simian virus 40 (SV40) in urban sewage. Using a nested-PCR procedure, we report the detection of human polyomaviruses JC virus (JCV) and BK virus (BKV) but not SV40 in a high percentage of urban sewage samples obtained from widely divergent geographical areas in Europe and Africa. For a total of 28 samples analyzed, JCV was detected in 26, BKV was detected in 22, and none was positive for SV40. All geographical areas showed a high prevalence of these viruses with mean estimated values of JC viral particles per ml on the order of 10(3) in Barcelona (Spain) and Nancy (France) and 10(2) in Pretoria (South Africa) and Umea (Sweden) and mean values of BK viral particles on the order of 10(2) in Pretoria and Barcelona and 10(1) in Nancy and Umea. This compares with estimated mean values of 10(2) to 10(3) for human adenovirus that was evaluated as a control. Nucleotide sequence analysis of the amplified DNA from some of the samples is also presented and represents the sequence of the most abundant JC and BK viral strains in these samples. The nucleotide sequence of the JCV detected was also analyzed in a phylogenetic study and for genomic characterization in the regulatory region. This study has shown that human polyomaviruses are spread in high concentrations in the sewage of different geographical areas and are present in contaminated environments. The frequency and concentration of JCV detected in the environment and the absence of described animal hosts suggest that JCV may be useful as a marker for fecal pollution of anthropogenic origin. The results also support the idea previously described that the strains of JCV are closely related to the ethnic origin of the population studied. The procedure applied should also be useful in future studies of population patterns of viral excretion and as a tool in epidemiological studies for the detection of changes in the prevalence of specific viral pathogens.  (+info)

Background: The study evaluated the relationship of pretransplantation BK virus (BKV)-specific donor and recipient serostatus to posttransplantation BKV infection., Methods: Two hundred forty adult de novo kidney-only recipients and 15 pediatric recipients were prospectively enrolled and followed for a minimum of 18 months. Pretransplantation BKV serostatus was available for 192 adult and 11 pediatric donor-recipient pairs. Based on BKV-specific IgG enzyme immunoassay ,=8 units, subjects were divided into four groups: D+R+, D+R-, D-R+, and D-R-. BKV DNA surveillance was performed at 1, 3, 6, 12, and 24 months. The outcomes studied were development of any BKV infection, viremia, and significant viremia (,=10,000 copies/mL plasma)., Results: Of the 192 adult subjects (D+R- [n=41], D+R+ [n=42], D-R+ [n=41], and D-R- [n=68]), 89 of 192 developed any BKV infection and 62 of 89 developed BK insignificant viremia (n=33) and significant viremia (n=29).

The cis-acting elements for the early and late promoters, as well as the enhancer in the prototype strains of human polyomavirus BK (BKV) are located within a 500 bp intergenic region. We previously studied the specificity of protein binding in this region in vitro and showed that the interaction of proteins of the nuclear factor-1 (NF-1) family is crucial for early promoter activity. We have now extended our study to the BKV late promoter. We show that the late promoter activity in HeLa cell extracts is poor compared to the activity of the early promoter. Using a high template to protein ratio, multiple start sites were detected by primer extension analysis. DNase I protection experiments revealed the presence of three NF-1 binding sites in the late side, in addition to those identified previously in the 68 bp repeats and C element. Competition transcription assays using binding sites for NF-1, AP-1, Sp-1 and a complete 68 bp repeat indicated that only the 68 bp repeat and the NF-1 binding site

Background. In the past 20 years, BK virus has emerged as a cause of early graft dysfunction after kidney transplantation. In the setting of chronic immunosuppression (IS), the latent virus can reactivate, leading to BK viremia (10-20%) and in 1-10% of kidney transplant recipients to BK virus nephropathy (BKVN). The early detection of BK viremia by serum DNA PCR screening allows prompt but controlled reduction of IS, which, despite numerous attempts to find specific antiviral agents, remains the mainstay therapy. So far, besides potent IS, no risk factor has been consistently associated with BK viremia/BKVN. The use of a ureteral stent at the time of transplantation to protect the ureterovesical anastomosis has been described as a potential trigger. In this study, we aimed at defining the incidence and kinetics of BK viremia in our local cohort of kidney transplant recipients, and analysed potential predictors of BK viremia/BKVN, including ureteral stents. Methods. We performed a singl
Human polyomavirus BK (BKPyV) is the aetiological agent of polyomavirus-associated nephropathy (PVAN) and of hemorrhagic cystitis (HC) while human polyomavirus JC (JCPyV) is associated with progressive multifocal leukoencephalopathy (PML). However, JCPyV can give rise to PVAN and HC and BKPyV has been detected in cerebrospinal fluid samples (CSF) from patients with Central Nervous System (CNS) disease, including PML. During the period 1998- 2011, 2,406 CSF samples from patients with suspected JCPyV infection were tested for the presence of BKPyV, JCPyV, and SV40 large T antigen DNA by a multiplex PCR assay in the National Centre of Microbiology. Twenty neurological patients with at least one BKPyV DNApositive CSF specimen were identified. Firstly, an internally-controlled multiplex real-time PCR was developed and showed to be suitable for the diagnosis of polyomavirus BK and JC infection, providing a sensitive, reproducible and specific quantification of the viral load of both viruses in samples ...
Factors determining the course of BK viral (BKV) infection remain uncertain. We studied the role of BKV subtype distribution in BKV-infected patients after renal transplantation.-. We performed genotyping of BKV subtypes in 180 BKV-infected renal transplant recipients with BKV nephropathy (BKVN, n=69), BKV viremia (n=94), BKV viruria alone (n=17), and in 29 healthy adults and 11 dialysis patients with spontaneous BKV replication in urine. We then tested, if the frquency of certain subtypes corresponded to the severity of the infection: BKV nephropathy, BKV high viremia (,10000 copies/mL), or BKV low viremia (,10000 copies/mL). -. Ib-2 was the most frequent BKV subtype (135/220. 61%) and subtype IV the second in frequency (50/220, 23%); Ib-1 (10%), Ia (5%), II and III (1%) were less frequent. Subtype IV-infected patients had more often BKVN and/or high viremia of ,10000 copies/mL than patients with other subtypes (31/38 versus 78/125, p=0.02). Patients with low viremia of ,10000 copies/mL were ...
This is a unique case of BK virus infection associated with HC in a LT recipient. To our knowledge, this is the first reported case of this association. The prevalence of BK viremia and viruria in LT recipients is low when compared to other solid organ transplant recipients.5 The prevalence of BK viruria in LT recipients has been reported to be 7.8% compared to 26.5% in kidney transplant recipients and 25.5% in heart transplant recipients. The prevalence of BK viremia was 0% in LT compared to 12.2% in kidney transplant recipients and 7% in heart transplant recipients.6. The risk factors that have been identified for BK virus infection in LT recipients include CKD, immunosuppression and previous episode(s) of rejection.7,8 One study found that LT recipients with a history of rejection had BK viremia more frequently (40%) than those without rejection (10.6%).8 Although immunosuppression is a risk factor for BK virus infection, none of the studies have identified any specific immunosuppressive ...
BK polyomavirus (BKV) is widespread among humans, asymptomatically infecting children and then persisting in renal tissue. The transcriptional control region (TCR) of the BKV genome is variable among clinical isolates. Thus, archetypal TCRs with a common basic configuration generally occur in BKV isolates from the urine of immunocompromised patients, but rearranged TCRs that possibly arise from the archetypal configuration have also been detected in clinical specimens. To examine the hypothesis that archetypal strains represent wild-type strains circulating in the human population (the archetype hypothesis), we analysed 145 complete viral genomes amplified directly from the urine of non-immunocompromised individuals worldwide. These genomes included 82, three, two and 58 sequences classified as belonging to subtypes I, II, III and IV, respectively. Rearranged TCRs with long duplications or deletions were detected from two subtype I and two subtype IV genomes, but not from the other 141 genomes (thus,

The BK polyomavirus (BKPyV) is one of the main human polyomaviruses. After primary infection, it establishes a persistent infection, and acts as an opportunistic pathogen, innocuous in immunocompetent hosts, but causing potentially serious pathology in the context of immunosuppression, in particular in kidney and hematopoietic stem cell graft recipients. Much progress has been made in recent years in the description of virus-cell interactions, but many aspects of viral physiopathology remain mysterious, principally due to the asymptomatic nature of infection in immunocompetent individuals and the lack of an animal model. The characteristics of the antiviral immune response are beginning to become more clearly understood, particularly in kidney transplant patients. Work in these areas is important in order to identify patients at high risk of developing a severe infection. Indeed, in the absence of an effective antiviral therapy few therapeutic options are available, and patient management ...
QBK : Polyomaviruses are small (45 nm, approximately 5,000 bp), DNA-containing viruses and include 3 closely related viruses of clinical significance: Simian virus 40 (SV-40), JC virus (JCV), and BK virus (BKV). SV-40 naturally infects rhesus monkeys but can infect humans, while BKV and JCV cause productive infection only in humans.(1,2) Acquisition of BKV begins in infancy. Serological evidence of infection by BKV is present in 37% of individuals by 5 years of age and over 80% of adolescents.   BKV is an important cause of interstitial nephritis and BKV-associated nephropathy (BKVAN) in recipients of kidney transplants. Up to 5% of renal allograft recipients can be affected at about 40 weeks (range 6-150) posttransplantation.(3) Quantitative PCR analysis of BKV DNA in the plasma is the most widely used blood test for the laboratory diagnosis of BKV-associated nephropathy. Importantly, the presence of BKV DNA in blood reflects the dynamics of the disease: the conversion of plasma from negative
BACKGROUND: The diagnosis and management of BK virus (BKV) reactivation following renal transplantation continues to be a significant clinical problem. Following reactivation of latent virus, impaired cellular immunity enables sustained viral replication to occur in urothelial cells, which potentially leads to the development of BKV-associated nephropathy (BKVAN). Current guidelines recommend regular surveillance for BKV reactivation through the detection of infected urothelial cells in urine (decoy cells) or viral nucleic acid in urine or blood. However, these methods have variable sensitivity and cannot routinely distinguish between different viral subtypes. We therefore asked whether mass spectrometry might be able to overcome these limitations and provide an additional non-invasive technique for the surveillance of BKV and identification of recipients at increased risk of BKVAN. RESULTS: Here we describe a mass spectrometry (MS)-based method for the detection of BKV derived proteins directly

Since the cloning of the BK B1 receptor in 1994 by Menke et al., several groups have begun to determine the transduction mechanisms involved in its induction (Bachvarov et al., 1996; Yang and Polgar, 1996; Ni et al., 1998; Schanstra et al., 1998;Phagoo et al., 2001). The 5′-flanking region of the human BK B1 receptor gene bears putative NF-κB as well as activator protein-1 binding motifs, a promoter organization consistent with an activation by cytokines, such as IL-1β or TNF-α (Bachvarov et al., 1996). Using transfected cultured cells, Ni et al. (1998) have demonstrated that NF-κB is involved in the inducible expression of the human BK B1 receptor gene during inflammatory processes. In resting cells, NF-κB is held inactive in the cytosol by association with inhibitory proteins of the I-κB family (Baldwin, 1996). When the NF-κB pathway is activated by agents such as lipopolysaccharide, IL-1β, and TNF-α, a phosphorylation-dependent proteolytic degradation of I-κB is initiated, ...

Results Twenty-five patients developed hemorrhagic cystitis. Pre-transplant BK viruria detected by quantitative PCR was positive in 96 patients. The one-year cumulative incidence of hemorrhagic cystitis was 16% in the PCR-positive group versus 9% in the PCR-negative group (P=0.1). The use of umbilical cord blood or a haploidentical donor was the only significant predictor of the incidence of hemorrhagic cystitis on univariate analysis. There was also a trend for a higher incidence after myeloablative conditioning. Multivariate analysis showed that patients who had a positive PCR pre-transplant and received haploidentical or cord blood grafts with myeloablative conditioning had a significantly higher risk of developing hemorrhagic cystitis (58%) than all other recipients (7%, P,0.001). ...
In recent years the scientific literature in the field of the prostate carcinoma (PCa) pointed out on the genetic heterogeneity and mutations occurring in this tumour, while little attention was given to the causes of PCa onset, in particular infectiuos agents. In this brief commentary, we wish to point out recent advancements done on the role of the human polyomavirus BK (BKPyV) in the development of PCa by harnessing both humoral and cellular immune responses. Altogether, these new insights suggest that BKPyV is involved in the transforming activity during the multistep process of PCa development. Although these findings do not provide evidence for a causal relationship between BKPyV and PCa development, additional investigations with novel techniques will help to make it a concrete event. ...
Furthermore, genes involved in the regulation of the cell cycle were the most significantly upregulated set in both JCPyV- and BKPyV-infected versus uninfected cells (see Fig.?S1 in the supplemental material). explain the distinct disease outcomes. INTRODUCTION JC and BK polyomaviruses (JCPyV and BKPyV, respectively) are members of the human family. JCPyV and BKPyV were isolated in 1971, but 11 additional human polyomaviruses have been discovered in the last decade (1,C12). JCPyV is the etiological agent of progressive multifocal leukoencephalopathy (PML), a fatal neurodegenerative disease, and BKPyV causes polyomavirus-associated nephropathy (PyVAN) and hemorrhagic cystitis (HC) (1, 13). JCPyV and BKPyV are common human pathogens, for which 50 to 60% and 80% of healthy individuals, respectively, are seropositive (14,C16). Primary infection with JCPyV and BKPyV occurs early during childhood, and it is most often asymptomatic unless there is a preexisting, immunosuppressive condition (17, 18). ...

TY - JOUR. T1 - The kinetics of urinary shedding of BK virus in children with renal disease. AU - Yamamoto, Yasuto. AU - Morooka, Masashi. AU - Ihira, Masaru. AU - Yoshikawa, Tetsushi. PY - 2015/1/1. Y1 - 2015/1/1. N2 - Children with renal diseases are typically treated with immunosuppressive drugs, which place them at high risk of reactivation of the BK virus (BKV). Currently, little is known about the impact of immunosuppressive drugs on the kinetics of urinary shedding of BKV and viral reactivation in pediatric patients with renal diseases. Urine samples were collected monthly for 1 year from 20 children (median age, 9 years; range, 4-15 years) with renal diseases and subjected to real-time PCR. Urinary shedding of BKV was detected in 35% (7/20) of the patients, three of these patients having persistent viral DNA excretion (two cases, twelve times, one case, four times) and four having intermittent viral DNA excretion. Thirty-four of the 240 urine samples contained BKV DNA (median copy ...
