Summary
Emerging and reemerging viruses pose significant research challenges. Lentiviral and rhabdoviral pseudotypes offer a safe method to study these dangerous viruses, aiding in understanding viral entry and developing treatments.
Area of Science:
- Virology
- Emerging Infectious Diseases
- Molecular Biology
Background:
- New and reemerging viruses, including Middle East respiratory syndrome coronavirus (MERS-CoV) and Ebola virus, present global health threats.
- Studying highly pathogenic viruses is challenging due to safety concerns and difficulties in culturing.
- Advanced techniques are identifying novel human and animal viruses, increasing the need for effective research tools.
Purpose of the Study:
- To review the application of lentiviral and rhabdoviral pseudotype systems for studying emerging and reemerging enveloped viruses.
- To highlight the utility of pseudotypes in characterizing viral properties like receptor usage, entry mechanisms, and serological responses.
- To discuss the use of pseudotypes in drug screening and antibody neutralization assays for viruses such as chikungunya virus, Ebola virus, SARS-CoV, MERS-CoV, and Nipah virus.
Main Methods:
- Review of existing literature on viral pseudotyping systems.
- Discussion of lentiviral and rhabdoviral pseudotypes as tools for studying enveloped viruses.
- Exploration of pseudotype applications in characterizing viral tropism, entry, and neutralization.
Main Results:
- Pseudotypes enable the safe study of highly pathogenic and difficult-to-culture viruses.
- Pseudotyping systems have facilitated advances in understanding viral receptor usage, entry pathways, and serology.
- Applications include initial characterization of cellular tropism and screening for antiviral drugs and neutralizing antibodies.
Conclusions:
- Lentiviral and rhabdoviral pseudotypes are invaluable tools for the safe and effective study of emerging and reemerging viruses.
- Pseudotype technology significantly contributes to virological research, from basic characterization to therapeutic development.
- Further research and careful consideration of pseudotyping limitations are essential for maximizing their potential.

1.3K
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...

02:33Retroviruses
15.7K
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’...

Subviral agents are infectious entities that resemble viruses but lack one or more viral components, such as a capsid or essential replication machinery. These agents include viroids, prions, and satellites, each possessing distinct structural and functional characteristics that influence their mode of infection and replication.Viroids are the simplest subviral agents, consisting of circular, single-stranded RNA molecules without a protein coat. They exclusively infect plants, relying entirely...
