Viral Recombination

2019
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. Viral Recombination Can Create New Diseases Some diseases can infect multiple species. For example, pigs can be infected by some human and...

Viral Structure

2019
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. Structural Classes of Viruses Many criteria are used to classify viruses, including capsid design. Most viruses...

We describe the process of isolating high purity herpesvirus nucleocapsid DNA from infected cells. The final DNA captured from solution is of high concentration and purity, making it ideally suited for high-throughput sequencing, high fidelity PCR reactions, and transfections to produce new viral recombinants.

This video demonstrates a viral attachment assay for screening antiviral compounds. Using genetically modified hepatitis C virus and luciferase, it assesses inhibitory effects on viral attachment, as indicated by lower light intensity in co-treated wells compared to wells treated with the virus alone.

The Virochip is a pan-viral microarray designed to simultaneously detect all known viruses as well as novel viruses on the basis of conserved sequence homology. Here we demonstrate how to run a Virochip assay to analyze clinical samples for the presence of both known and unknown viruses.
FAQs
Viral release follows one of two major physical routes. Lysis ruptures the plasma membrane, directly damaging the infected host cell as particles leave. Budding and exocytosis provide an exit route in which enveloped virions acquire a lipid membrane. This distinction helps connect the release mechanism with host-cell injury, particle structure, and subsequent spread through tissues.
During budding or exocytosis, an enveloped virion obtains a lipid membrane while exiting the host cell. That membrane distinguishes this route from release by lysis and reflects how particle structure is linked to the release process. Studying this connection helps investigators examine how viruses leave cells and how release may be targeted in antiviral research.
The route of exit contributes to the biological effects of infection. Membrane rupture during lysis provides a direct source of host-cell damage, whereas budding or exocytosis represents a different way for particles to leave while acquiring a lipid membrane. Comparing these mechanisms helps researchers relate viral release to pathogenesis, tissue infection, and the spread of infection.
Experimental analysis can clarify how newly assembled virions leave infected cells and which release route is associated with a particular virus. The resulting information connects particle exit with host-cell damage, transmission, and tissue infection. These observations also help identify release-related processes that may serve as targets for antiviral strategies or further pathogenesis studies.
Researchers examine release because it is a stage that can provide targets for antiviral strategies. Analysis focuses on the consequences of particles leaving by lysis, budding, or exocytosis, including membrane rupture and lipid-membrane acquisition. Understanding these features can guide investigation of interventions intended to limit viral spread from infected cells.
Knowledge of how virions exit infected cells has applications beyond studying disease. Viral release research supports vaccine development and the design of virus-based delivery systems, while also informing work on pathogenesis. Comparing lysis with budding or exocytosis helps place particle exit, membrane acquisition, host-cell effects, and infection spread within these broader biological applications.
