Summary
N6-methyladenosine (m6A) modifications impact viral infections by altering host and viral RNA. Understanding m6A
Area of Science:
- Virology
- Molecular Biology
- Epitranscriptomics
Background:
- N6-methyladenosine (m6A) is a key RNA modification influencing gene expression.
- Viral infections alter host epitranscriptomes, impacting host-virus interactions.
- m6A modifications on viral and host RNAs play a role in infection outcomes.
Purpose of the Study:
- To summarize the dual effects of m6A modifications in various viral infections.
- To highlight the current understanding and gaps in m6A regulation mechanisms during viral infections and host immune responses.
- To emphasize the potential of m6A as a therapeutic target for antiviral strategies.
Main Methods:
- Review of existing literature on m6A modifications in viral infections.
- Integration of findings from transcriptome-wide mapping of m6A in viruses.
- Analysis of the impact of m6A on viral gene expression, replication, and host immunity.
Main Results:
- m6A modifications can have both positive and negative effects on different viral infections.
- m6A on viral RNA influences viral gene expression, replication, and progeny virion production.
- Host mRNA m6A decoration can either promote or confer resistance to viral infections.
Conclusions:
- m6A is a critical regulator in the interplay between viruses and their hosts.
- Further research is needed to fully elucidate the mechanisms of m6A regulation in viral pathogenesis and immunity.
- m6A represents a promising novel target for the development of antiviral therapies.

00:57Viral Recombination
25.1K
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.

00:56Viral Structure
74.4K
Viruses are extraordinarily diverse in shape and size, but they all have several structural features in common. All viruses have a core that contains a DNA- or RNA-based genome. The core is surrounded by a protective coat of proteins called the capsid. The capsid is composed of subunits called capsomeres. The capsid and genome-containing core are together known as the nucleocapsid.

00:36Viral Mutations
39.8K
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...

12.4K
When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of 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...

01:26Size and Structure of Viral Genomes

Viral genomes exhibit remarkable diversity in size, structure, and composition, influencing their replication strategies and interactions with host cells. These genomes consist of either DNA or RNA and may be linear or circular. Additionally, they can be single-stranded or double-stranded, with each configuration affecting how the virus propagates within a host. RNA viruses, for instance, generally have smaller genomes than DNA viruses, a factor that contributes to their high mutation rates and...

01:20Viral Replication: Lytic Cycle
1.5K
Bacteriophages, or phages, are viruses that specifically infect bacteria. Among them, T-even bacteriophages, such as T4, exhibit a well-characterized lytic replication cycle in Escherichia coli (E. coli). This process ensures the rapid proliferation of the virus while ultimately leading to the destruction of the bacterial host.Attachment and DNA InjectionThe infection process begins with the recognition and binding of the T4 phage to the E. coli cell surface. Tail fibers of the phage...
