Many viruses create specialized "virus factories" for efficient replication. This review explores how viruses may hijack cellular machinery, like aggresomes and autophagosomes, to form these replication sites.
Area of Science:
- Cell Biology
- Virology
- Molecular Biology
Background:
- Viral replication often occurs in specialized intracellular compartments known as virus factories.
- These compartments concentrate viral components, enhancing replication efficiency.
- Virus factory formation involves cellular membrane and cytoskeleton rearrangements.
Purpose of the Study:
- To review evidence suggesting viruses induce cellular aggresomes and autophagosomes.
- To explore the role of these cellular structures in viral replication site generation.
Main Methods:
- Literature review of studies on virus factories, aggresomes, and autophagosomes.
- Analysis of cellular responses to viral infection and protein aggregation.
Main Results:
- Viral replication sites share similarities with cellular structures like aggresomes and autophagosomes.
- Viruses may induce the formation of aggresomes and autophagosomes for replication.
Conclusions:
- Viruses may exploit cellular degradation pathways (aggresomes, autophagosomes) to create replication sites.
- This strategy could enhance viral replication efficiency by concentrating viral components.

Infection
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...
