Polyomaviridae is a family of viruses whose natural hosts are primarily mammals and birds. [1] [2] As of 2024, there are eight recognized genera. [3]Fourteen species are known to infect humans, while others, such as Simian Virus 40, have been identified in humans to a lesser extent.
Murine polyomavirus (also known as mouse polyomavirus, Polyomavirus muris, or Mus musculus polyomavirus 1, and in older literature as SE polyoma or parotid tumor virus; abbreviated MPyV) is an unenveloped double-stranded DNA virus of the polyomavirus family. The first member of the family discovered, it was originally identified by accident in ...
Sorex araneus polyomavirus 1, formerly known as Human polyomavirus 12 (HPyV12), is a virus of the polyomavirus family that was first identified in human hosts and also infects shrews. [1] It was discovered and reported in 2013 after isolation from the organs of the gastrointestinal tract , particularly the liver . [ 2 ]
All known human polyomaviruses are fairly common in healthy adult populations and are usually asymptomatic. In studies that profile polyomavirus seroprevalence, or prevalence of detectable antibodies against viral proteins indicating either past or present exposure in immunocompetent adults, HPyV9 tends to have a relatively lower prevalence compared to other human polyomaviruses.
The primary alphapolyomavirus that is of clinical significance to humans is Merkel cell polyomavirus (Human polyomavirus 5, MCV, or MCPyV). The apparent oncogenicity of MCPyV [6] similar to other cancer-causing viruses such as HPV, Epstein-Barr virus, and Hepatitis C virus [7] is a main area of research for the scientific community.
Merkel cell polyomavirus (MCV or MCPyV) was first described in January 2008 in Pittsburgh, Pennsylvania. [1] It was the first example of a human viral pathogen discovered using unbiased metagenomic next-generation sequencing with a technique called digital transcriptome subtraction. [2]
The SV40 large T antigen from the SV40 virus is the most well-studied member of the LTag family. SV40, also known as Macaca mulatta polyomavirus 1, natively infects monkeys and does not cause disease; however, it is oncogenic in some rodents and can immortalize some human cells in primary cell culture.
Polyomaviridae is a family of viruses.Mammals and birds serve as natural hosts. There are currently 13 species in this family, divided among 1 genera, Polyomavirus (type species Simian virus 40).
