Insights

JC virus Agno protein acts as a viroporin, increasing cell membrane permeability and virus release. Host protein interactions regulate this activity, revealing new insights into viral replication.

Area of Science:

  • Virology
  • Molecular Biology
  • Cell Biology

Background:

  • Viroporins are viral proteins that form pores in host cell membranes.
  • JC virus (JCV) causes progressive multifocal leukoencephalopathy (PML).

Purpose of the Study:

  • To investigate the role of JCV Agno protein in viral replication and host cell interaction.
  • To determine if JCV Agno protein exhibits viroporin activity.

Main Methods:

  • Expression analysis of JCV Agno protein.
  • Assessment of plasma membrane permeability.
  • Measurement of virion release.
  • Investigation of Agno protein interaction with host cellular proteins.

Main Results:

  • JCV Agno protein was identified as a small, hydrophobic protein with viroporin activity.
  • Agno protein increases plasma membrane permeability and virion release.
  • Host cellular protein interaction regulates the viroporin activity of Agno.

Conclusions:

  • JCV Agno protein functions as a viroporin, contributing to viral replication.
  • Host-virus interactions involving Agno protein represent a new mechanism regulating viroporin activity.

Inhibitors of Viral Protein Synthesis01:30

Inhibitors of Viral Protein Synthesis

Protein synthesis is indispensable for viral replication, as viruses lack the cellular machinery required for this process and must hijack the host's translational apparatus. In response, host cells deploy a critical innate immune defense involving interferons, specialized cytokines that play a central role in inhibiting viral propagation.Upon viral detection, infected cells release interferons that bind to receptors on adjacent uninfected cells, activating the JAK-STAT signaling pathway and...

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’...

Mechanisms of Retrovirus-induced Cancers

Retroviruses are RNA viruses that have been shown to cause cancers in diverse species, including chickens, mice, cats, and monkeys. The RNA genomes of these viruses are first reverse-transcribed into single and then double-stranded DNA (dsDNA) copies. This dsDNA called proviral DNA then integrates into the host genome. Subsequently, the host cell transcribes the proviral DNA in concert with the chromosomal DNA. This leads to the production of viral RNA and proteins that assemble at the host...

Inhibitors of Bacterial Protein Synthesis

Aminoglycosides constitute a highly potent class of bactericidal antibiotics that exert their antimicrobial effects by targeting the bacterial ribosome, specifically disrupting protein synthesis. These polycationic molecules consist of amino-modified sugars linked via glycosidic bonds to an aminocyclitol core such as 2-deoxystreptamine or streptamine. Their strong positive charges facilitate tight binding to the negatively charged phosphate backbone of ribosomal RNA (rRNA), primarily at the 16S...

Subviral Agents01:29

Subviral Agents

Subviral agents are infectious entities that resemble viruses but lack one or more viral components, such as a capsid or essential replication machinery. These agents include viroids, prions, and satellites, each possessing distinct structural and functional characteristics that influence their mode of infection and replication.Viroids are the simplest subviral agents, consisting of circular, single-stranded RNA molecules without a protein coat. They exclusively infect plants, relying entirely...
