Summary
Herpes simplex virus (HSV) latency-associated transcripts are found in infected nerve ganglia. These transcripts may play a role in maintaining HSV latency and in vivo reactivation.
Area of Science:
- Virology
- Molecular Biology
- Neuroscience
Background:
- Herpes simplex virus (HSV) establishes lifelong latent infections in neurons.
- Understanding the molecular mechanisms of HSV latency is crucial for developing antiviral strategies.
Purpose of the Study:
- To investigate the characteristics and potential functions of HSV-specified RNA transcripts during latent infection.
- To explore the role of these transcripts in the maintenance of latency and viral reactivation.
Main Methods:
- Detection of HSV RNA transcripts using in situ hybridization and RNA blot analyses.
- Physical analysis of the nucleotide sequence of the transcript.
- Identification of potential open reading frames (ORFs) and promoter elements.
Main Results:
- HSV-specified RNA transcripts were detected in latently infected peripheral nerve ganglia of experimentally infected mice and humans.
- Nucleotide sequence analysis revealed a transcript of approximately 2,500 bases, suggesting possible splicing into two overlapping ORFs.
- Potential promoter elements were identified within the transcript's sequence.
Conclusions:
- The latency-associated transcript is likely involved in maintaining latent HSV infection.
- Emerging evidence suggests that latent-phase transcription also contributes to in vivo HSV reactivation.

01:10Retrovirus Life Cycles
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 retrovirus to...
03:08LTR Retrotransposons
LTR retrotransposons are class I transposable elements with long terminal repeats flanking an internal coding region. These elements are less abundant in mammals compared to other class I transposable elements. About 8 percent of human genomic DNA comprises LTR retrotransposons. Some of the common examples of LTR retrotransposons are Ty elements in yeast and Copia elements in Drosophila.

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...
01:29Viruses with RNA Genomes
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...
01:28Herpes
Herpes simplex type 1 (HSV‑1) is a widespread pathogen responsible for orolabial lesions. It is an enveloped, double-stranded DNA (dsDNA) virus belonging to the family Herpesviridae. Once the virus infects a host cell, its double‑stranded DNA genome is delivered into the nucleus, where a coordinated cascade of immediate‑early, early, and late gene expression directs viral DNA replication, structural protein synthesis, and virion assembly. After primary infection of epithelial cells, HSV-1...
01:23Genital Herpes
Genital herpes is a sexually transmitted infection primarily caused by herpes simplex virus type 2 (HSV-2), though herpes simplex virus type 1 (HSV-1) is increasingly implicated in genital infections, particularly among younger populations. Transmission occurs mainly through sexual contact, with asymptomatic viral shedding serving as a major route of spread. This characteristic makes HSV-2 difficult to control at a population level, as individuals may unknowingly transmit the virus even in the...
