KI, WU and Merkel cell polyomaviruses: A new era for human polyomavirus research

Seminars in Cancer Biology, 2009
The recent discoveries of KI, WU, and Merkel cell polyomaviruses (PyVs) have rekindled interest in the Polyomaviridae and their relation to human disease. Although it may be too early to draw firm conclusions, it seems apparent that these new viruses follow precedents established by other Py viruses: a benign initial infection at an early age ...

KI Polyomavirus Detected in Respiratory Tract Specimens From Patients in St. Louis, Missouri

Pediatric Infectious Disease Journal, 2010
Studies have reported the presence of KI polyomavirus (KIPyV) and WU polyomavirus (WUPyV) in respiratory secretions of young patients. So far, evidence has not supported a link between infections with either virus and respiratory tract disease; however, there has not been a large comparison of KIPyV-infected patients to age-matched patient groups.A ...

Human herpesvirus 6A and 6B and polyomavirus JC and BK infections in renal cell carcinoma and their relationship with p53, p16INK4a, Ki‐67, and nuclear factor‐kappa B expression

Microbiology and Immunology, 2022
AbstractThere are a limited number of studies regarding the involvement of viruses in the development and pathogenesis of renal cell carcinoma (RCC). In this study, we aimed to discover whether human herpesvirus 6A (HHV‐6A) and 6B (HHV‐6B) and human polyomavirus JC (JCV) and BK (BKV) are associated with RCC and the expression of p53, p16INK4a, Ki‐67 ...

Is it the Lower Respiratory Tract a Real Replication Site for KI Polyomavirus?

Journal of Virology & Antiviral Research, 2012
Is it the Lower Respiratory Tract a Real Replication Site for KI Polyomavirus? Recently two novel KI and WU polyomaviruses have been identified from human respiratory specimens. The spectrum of clinical manifestations and their role in respiratory tract are currently unknown.

Molecular detection and phylogenetic analysis of KI polyomavirus and WU polyomavirus in respiratory tract samples from children under five

Diagnostic Microbiology and Infectious Disease
We aimed to investigate the frequency of KI and WU polyomavirus in respiratory tract samples, the affected groups by these viruses and their clinical characteristics. Although the viruses had been discovered in 2007, their pathogenicity and virulence have not been fully elucidated yet.We examined 182 nasopharyngeal aspirate/swab samples obtained ...

[WU polyomavirus and KI polyomavirus detected in specimens from children with acute respiratory tract infection in China].

Zhonghua shi yan he lin chuang bing du xue za zhi = Zhonghua shiyan he linchuang bingduxue zazhi = Chinese journal of experimental and clinical virology, 2009
To investigate newly identified polyomavirus WUV and WUV and KIPyV are associated with acute respiratory infections in China, tests were developed to detect WUV and KIPyV gene fragments from nasopharyngeal aspirates collected from children with ARI fron Nov. 2006 to Oct.

KI, WU, and Merkel Cell Polyomavirus DNA was not Detected in Guthrie Cards of Children who Later Developed Acute Lymphoblastic Leukemia

Journal of Pediatric Hematology/Oncology, 2012
Neonatal dried blood spots (Guthrie cards) have been used to demonstrate a prenatal origin of clonal leukemia-specific genetic aberrations in several subgroups of childhood acute lymphoblastic leukemia (ALL). One hypothesis suggests that an infectious agent could initiate genetic transformation already in utero.

Phosphohistone-H3 (PHH3) is prognostic relevant in Merkel cell carcinomas but Merkel cell polyomavirus is a more powerful prognostic factor than AJCC clinical stage, PHH3, Ki-67 or mitotic indices.

Pathology international, 2016
Merkel cell carcinomas (MCCs) associated with Merkel cell polyomavirus (MCPyV) have better prognosis than those without MCPyV. The relationship between mitotic index (MI) and MCC outcome has remained elusive because of the difficulty in differentiating mitotic cells from apoptotic ones.

[Identification of KI polyomavirus in children with lower respiratory tract infections from Zhejiang region of China].

Bing du xue bao = Chinese journal of virology, 2008
KI polyomavirus, which was firstly discovered in 2007, is a new human polyomavirus belonging to Polyomaviridae and containing circular double-strand genomic DNA. This study was based on identification assay of KI polyomavirus reported. Total 2293 clinical sputum specimens from children under 3-years-old were collected and screened from Wenzhou Medical ...
