Occurrence of the European subgroup of subtype I BK polyomavirus in Japanese-Americans suggests transmission outside the family.

ABSTRACT: To examine the mode of transmission of BK polyomavirus (BKV), urine samples were collected from Japanese-Americans in Los Angeles and from other southern Californians. Subtype I was the main subtype found in samples from both groups. The subtype I subgroup Ib-2, which is predominant in Europe, was the primary subgroup detected in second-generation Japanese-Americans and in southern Californians; however, the Ic subgroup prevalent in native Japanese was rare in these populations. Since the European subgroup (Ib-2) predominated in the studied geographic area, the findings demonstrate that transmission outside the family is common in the spread of BKV, unlike previous findings for JC polyomavirus.

Structural and functional analysis of natural capsid variants suggests sialic acid-independent entry of BK polyomavirus.

Project description:BK polyomavirus (BKPyV) is an opportunistic pathogen that uses the b-series gangliosides GD1b and GT1b as entry receptors. Here, we characterize the impact of naturally occurring VP1 mutations on ganglioside binding, VP1 protein structure, and virus tropism. Infectious entry of single mutants E73Q and E73A and the triple mutant A72V-E73Q-E82Q (VQQ) remains sialic acid dependent, and all three variants acquire binding to a-series gangliosides, including GD1a. However, the E73A and VQQ variants lose the ability to infect ganglioside-complemented cells, and this correlates with a clear shift of the BC2 loop in the crystal structures of E73A and VQQ. On the other hand, the K69N mutation in the K69N-E82Q variant leads to a steric clash that precludes sialic acid binding. Nevertheless, this mutant retains significant infectivity in 293TT cells, which is not dependent on heparan sulfate proteoglycans, implying that an unknown sialic acid-independent entry receptor for BKPyV exists.

Phylogenetic analysis of polyomavirus BK sequences.

Project description:Polyomavirus BK (BKV) has emerged as an important pathogen in kidney transplant patients. Existing taxonomic classifications of BKV come from conventional DNA sequence alignments based on limited data derived from the VP1 gene. We have used a phylogenetic whole-genome approach to examine the pattern of diversity and evolutionary relationships between 45 BKV strains isolated from multiple clinical settings. This analysis supports the classification of BKV into six genotypes, of which types V and VI have not been previously recognized. BKV strains hitherto classified as type I are, in fact, quite heterogeneous, and several cluster with our newly defined genotypes V and VI. The sequence information needed for assigning genotypes can be captured by VP1, VP2, VP3, or large T-gene sequencing. The most polymorphic coding region in the viral genome is VP1, but significant variation is also present in the large T-antigen gene, wherein polymorphisms are found in 11.39% of all nucleotide sites, 46.22% of which are cluster specific. Type-specific amino acid changes within the VP1 region are predicted to map to the BC and DE loops. The number of taxonomically informative amino acid changes in the large T antigen exceeds even that of the VP1 region. Viral strains isolated from healthy subjects and from patients with human immunodeficiency virus infection, Wiskott-Aldrich syndrome, and vasculopathy with capillary leak syndrome formed distinct subclusters. However, within the kidney transplant population, BKV strains derived from patients with asymptomatic viruria did not show complete separation from strains associated with allograft nephropathy.

BK polyomavirus: latency, reactivation, diseases and tumorigenesis.

Project description:The identification of the first human polyomavirus BK (BKV) has been over half century, The previous epidemiological and phylogenetic studies suggest that BKV prevailed and co-evolved with humans, leading to high seroprevalence all over the world. In general, BKV stays latent and symptomless reactivation in healthy individuals. BKV has been mainly interlinked with BKV-associated nephropathy (BKVAN) in kidney-transplant recipients and hemorrhagic cystitis (HC) in hematopoietic stem cell transplant recipients (HSCTRs). However, the mechanisms underlying BKV latency and reactivation are not fully understood and lack of extensive debate. As Merkel cell polyomavirus (MCV) was identified as a pathogenic agent of malignant cutaneous cancer Merkel cell carcinoma (MCC) since 2008, linking BKV to tumorigenesis of urologic tumors raised concerns in the scientific community. In this review, we mainly focus on advances of mechanisms of BKV latency and reactivation, and BKV-associated diseases or tumorigenesis with systematical review of formerly published papers following the PRISMA guidelines. The potential tumorigenesis of BKV in two major types of cancers, head and neck cancer and urologic cancer, was systematically updated and discussed in depth. Besides, BKV may also play an infectious role contributing to HIV-associated salivary gland disease (HIVSGD) presentation. As more evidence indicates the key role of BKV in potential tumorigenesis, it is important to pay more attention on its etiology and pathogenicity in vitro and in vivo.

Optimized amplification of BK polyomavirus in urine.

Project description:BK polyomavirus (BKPyV) is a ubiquitous pathogen that typically results in asymptomatic infection. However, in immunocompromised individuals, BKPyV viral shedding in the urine can reach 109 copies per mL. These high viral levels within urine provide ideal samples for next-generation sequencing to accurately determine BKPyV genotype and identify mutations associated with pathogenesis. Sequencing data obtained can be further analyzed to better understand and characterize the genetic diversity present in BKPyV. Here, methods are described for the successful extraction of viral DNA from urine and the subsequent amplification methods to prepare a sample for next-generation sequencing.

BK Polyomavirus-Biology, Genomic Variation and Diagnosis.

Project description:The BK polyomavirus (BKPyV), a representative of the family Polyomaviridae, is widespread in the human population. While the virus does not cause significant clinical symptoms in immunocompetent individuals, it is activated in cases of immune deficiency, both pharmacological and pathological. Infection with the BKPyV is of particular importance in recipients of kidney transplants or HSC transplantation, in which it can lead to the loss of the transplanted kidney or to haemorrhagic cystitis, respectively. Four main genotypes of the virus are distinguished on the basis of molecular differentiation. The most common genotype worldwide is genotype I, with a frequency of about 80%, followed by genotype IV (about 15%), while genotypes II and III are isolated only sporadically. The distribution of the molecular variants of the virus is associated with the region of origin. BKPyV subtype Ia is most common in Africa, Ib-1 in Southeast Asia, and Ib-2 in Europe, while Ic is the most common variant in Northeast Asia. The development of molecular methods has enabled significant improvement not only in BKPyV diagnostics, but in monitoring the effectiveness of treatment as well. Amplification of viral DNA from urine by PCR (Polymerase Chain Reaction) and qPCR Quantitative Polymerase Chain Reaction) is a non-invasive method that can be used to confirm the presence of the genetic material of the virus and to determine the viral load. Sequencing techniques together with bioinformatics tools and databases can be used to determine variants of the virus, analyse their circulation in populations, identify relationships between them, and investigate the directions of evolution of the virus.

BK polyomavirus diversity-Why viral variation matters.

Project description:BK polyomavirus (BKPyV or BKV) is a non-enveloped, circular double-stranded DNA virus that may exceed 80% seroprevalence in adults. BKV infection typically occurs during childhood, and the majority of adults are latently infected. While BKV infection is rarely associated with clinical disease in most individuals, in immunosuppressed individuals, reactivation may cause kidney (BK-associated nephropathy) or bladder (hemorrhagic cystitis and ureteral stenosis) injury. No antiviral therapies have been approved for the treatment of BKV infection. Reducing immunosuppression is the most effective therapy, although this is not feasible in many patients. Thus, a robust understanding of viral pathogenesis and viral diversity remains important for the development of future therapeutic strategies. Studies of BKV diversity are quite sparse compared to other common viral infections; thus, much of our understanding of BVK variability and evolution relies heavily analogous studies of other viruses such as HIV or viral hepatitis. We provide a comprehensive review of BKV diversity at the population and individual level with careful consideration of how viral variability may impact viral replication, pathogenesis, tropism, and protein function. We also discuss a number of outstanding questions related to BK virus diversity that should be explored rigorously in future studies.

miRNA regulation of BK polyomavirus replication during early infection.

Project description:Viral microRNAs (miRNAs) play an important role during infection by posttranscriptionally regulating both host and viral gene expression. However, the function of many viral miRNAs remains poorly understood. In this study, we investigated the role of the BK polyomavirus (BKPyV) miRNA in regulating virus replication. The function of the polyomavirus miRNA was investigated in archetype BKPyV, which is the transmissible form of the virus and thought to establish a persistent infection in the host urinary tract. In agreement with previous studies, we show that the BKPyV miRNA targets early mRNAs. Importantly, we show that the miRNA plays a significant role in limiting archetype BKPyV replication in a natural host cell model of infection. This regulation is accomplished through the balance of regulatory elements located within the noncoding control region that control early gene expression and miRNA expression before genome replication. We therefore provide evidence for a unique function of the polyomavirus miRNA that may have important implications for the mechanism of viral persistence.
