Summary
Herpes simplex virus type 1 (HSV-1) encodes microRNAs (miRNAs) that regulate host-virus interactions. These viral miRNAs are crucial for HSV-1 persistence and may serve as diagnostic and therapeutic targets.
Area of Science:
- Virology
- Molecular Biology
- Immunology
Background:
- Herpes simplex virus type 1 (HSV-1) causes widespread infections, establishing latency in neurons.
- Herpesviruses uniquely encode microRNAs (miRNAs), small noncoding RNAs with regulatory functions.
- HSV-1 encodes 18 miRNA precursors, yielding 27 mature miRNAs expressed during lytic and latent stages.
Purpose of the Study:
- To review the mechanisms by which HSV-1 encoded miRNAs regulate host-virus interactions.
- To explore the role of viral miRNAs in HSV-1 pathogenesis, immune evasion, and persistence.
- To discuss the potential of viral miRNAs as diagnostic, prognostic, and therapeutic targets.
Main Methods:
- Literature review of studies on HSV-1 encoded miRNAs.
- Analysis of sequence-specific targeting of viral and host transcripts by HSV-1 miRNAs.
- Examination of miRNA expression patterns in different cell types and disease stages.
Main Results:
- HSV-1 miRNAs target viral genes, influencing the viral life cycle.
- These miRNAs also regulate host genes involved in antiviral immunity, aiding viral evasion.
- Viral miRNA expression correlates with disease progression and resolution.
Conclusions:
- HSV-1 miRNAs play a significant role in regulating host-virus interactions, facilitating viral persistence.
- The stability and systemic circulation of viral miRNAs suggest their utility as biomarkers.
- Targeting these viral miRNAs offers potential therapeutic strategies against HSV-1 infection.

MicroRNAs
3.0K
MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...

Immune Response Against Viral Pathogens
782
The immune system's response to viral infections is a complex and coordinated process involving natural killer (NK) cells, T cell-mediated responses, and antibody-mediated responses.
NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...

Retroviruses
12.3K
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 Cycles
46.0K
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...

Mechanisms of Retrovirus-induced Cancers
5.1K
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...

Rous Sarcoma Virus (RSV) and Cancer
5.1K
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
