Insights

Recent discoveries reveal novel human polyomaviruses (HPyVs) with diverse characteristics. While typically harmless, some HPyVs cause severe disease in immunocompromised individuals, necessitating further research.

Area of Science:

  • Virology
  • Infectious Diseases
  • Molecular Biology

Background:

  • Human polyomaviruses (HPyVs) are common, often causing asymptomatic infections.
  • Immunocompromised individuals are susceptible to severe HPyV-associated diseases.
  • Significant advancements in HPyV research have occurred since 2007.

Purpose of the Study:

  • To review the biology, tropism, epidemiology, and diseases associated with novel HPyVs discovered from 2007 onwards.
  • To highlight the knowledge gaps regarding newly identified HPyV strains.
  • To emphasize the clinical relevance of HPyV research.

Main Methods:

  • Literature review of studies published from 2007 to the present.
  • Compilation of data on HPyV biology, tissue tropism, and epidemiology.
  • Analysis of disease associations for newly discovered HPyVs.

Main Results:

  • Over a dozen novel HPyVs have been identified since 2007.
  • These novel HPyVs exhibit diverse biological and epidemiological profiles.
  • Some HPyVs have established disease links, while others remain poorly understood.

Conclusions:

  • The discovery of novel HPyVs has expanded our understanding of viral diversity and evolution.
  • Further research is crucial to elucidate the clinical significance and pathogenic potential of enigmatic HPyVs.
  • Continued investigation is essential for managing HPyV infections, particularly in vulnerable populations.

Viral Mutations00:36

Viral Mutations

A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material...

Retroviruses02:33

Retroviruses

Retroviruses and retrotransposons both insert copies of their genetic elements into the genome of the host cell. Thus, the viral genes are passed on when the host genome is replicated or translated. A typical retroviral DNA sequence contains 3-4 genes that encode the different proteins required for its structural assembly and function as a molecular parasite. This DNA is transcribed into a single mRNA, which is very similar in structure to conventional mRNAs, i.e., it is capped at the 5’...

Retrovirus Life Cycles01:10

Retrovirus Life Cycles

Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the...

Viral Recombination00:57

Viral Recombination

Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.

Single Nucleotide Polymorphisms-SNPs01:05

Single Nucleotide Polymorphisms-SNPs

A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...
