Summary
Viruses hijack endoplasmic reticulum (ER) functions, but cells can defend using reticulophagy, a process targeting ER for degradation. This review explores how viruses manipulate ER-phagy, termed xERophagy, for their replication, impacting host antiviral responses.
Area of Science:
- Cellular Biology
- Virology
- Molecular Biology
Background:
- Viruses are obligate intracellular parasites that rely on host cell machinery for replication.
- The endoplasmic reticulum (ER) is a critical site for viral protein synthesis and assembly.
- Viruses often remodel ER membranes to create replication factories, evading host defenses.
Purpose of the Study:
- To review the complex interplay between viruses and the host reticulophagy machinery.
- To highlight reticulophagy as an antiviral defense mechanism, termed xERophagy.
- To discuss how viruses subvert xERophagy to promote their own replication and suppress host immunity.
Main Methods:
- Literature review of existing studies on viral interactions with the ER and autophagy pathways.
- Analysis of evidence demonstrating reticulophagy's role in antiviral defense.
- Examination of viral strategies to manipulate reticulophagy for replication.
Main Results:
- Reticulophagy acts as an antiviral mechanism (xERophagy) by degrading ER components targeted by viruses.
- Viruses can evade or subvert xERophagy to enhance viral protein accumulation and replication.
- Dysregulation of xERophagy by viruses impacts host antiviral signaling pathways.
Conclusions:
- The interaction between viruses and reticulophagy is a critical battleground for host-pathogen dynamics.
- Understanding xERophagy provides insights into novel antiviral strategies.
- Targeting the xERophagy pathway could offer new therapeutic avenues against viral infections.

00:58Recycling Endosomes and Transcytosis
2.6K
The recycling endosome, also known as the endosomal recycling compartment (ERC), is a part of the slow-recycling process of the endocytic pathway. Molecules internalized through receptor-mediated endocytosis are either degraded in the lysosomes or are recycled to the plasma membrane through the fast- or slow-recycling route.
The recycling endosome is not a single organelle but an extensively tubulated network of recycling pathways. It functions in storing molecules or transporting them across...

01:16Viral Replication: Lysogenic Cycle
1
The lysogenic cycle is a crucial viral replication strategy that allows bacteriophages to persist within host cells without immediately destroying them. This process is primarily observed in temperate phages, such as bacteriophage lambda (λ), which infects Escherichia coli. The cycle allows the viral genome to persist across bacterial generations while keeping host cells viable.Integration of the Viral GenomeUpon infection, bacteriophage lambda attaches to the bacterial surface and injects...

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’...

23.3K
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.

RNA viruses are categorized into positive-strand, negative-strand, or double-stranded groups based on their genomic structure and replication mechanisms. This classification dictates how they exploit host cellular machinery for protein synthesis and replication. Some RNA viruses also utilize reverse transcription as part of their life cycle, further diversifying their replication strategies.Positive-Strand RNA VirusesPositive-strand RNA viruses have genomes that function directly as messenger...

45.7K
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...
