Summary
Coxsackieviruses cause significant disease, but how they infect cells is unclear. This review suggests viruses infect active cells productively and establish latent infections in resting cells, impacting disease and transmission.
Area of Science:
- Virology
- Molecular Biology
- Cell Biology
Background:
- Coxsackieviruses are significant causes of human illness and death.
- The molecular mechanisms driving coxsackievirus-induced pathology are not well understood.
- Cellular state, including activation and cell cycle phase, may influence viral infection outcomes.
Purpose of the Study:
- To review the impact of cellular status on coxsackievirus infection outcomes.
- To propose a model for how coxsackieviruses interact with the cell cycle.
- To explore the implications of these interactions for viral pathogenesis and transmission.
Main Methods:
- Literature review of existing studies on coxsackievirus infection.
- Analysis of the relationship between cell cycle regulation and viral replication.
- Hypothesizing molecular mechanisms for differential infection outcomes based on cell status.
Main Results:
- Coxsackieviruses appear to favor productive infection in cells within the G1/S phase of the cell cycle.
- Quiescent cells may be preferentially utilized by coxsackieviruses for persistent or latent infections.
- Potential molecular explanations for these cell cycle-dependent infection patterns are discussed.
Conclusions:
- Cell cycle status is a critical determinant of coxsackievirus infection outcome.
- Understanding these interactions can illuminate coxsackievirus pathogenesis and disease progression.
- The proposed model offers insights into coxsackievirus transmission dynamics and host pathology.

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...
01:16Viral Replication: Lysogenic Cycle
The lysogenic cycle is a crucial viral replication strategy that allows bacteriophages to persist within host cells without immediately destroying them. This process is primarily observed in temperate phages, such as bacteriophage lambda (λ), which infects Escherichia coli. The cycle allows the viral genome to persist across bacterial generations while keeping host cells viable.Integration of the Viral GenomeUpon infection, bacteriophage lambda attaches to the bacterial surface and injects its...
01:20Viral Replication: Lytic Cycle
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...
02:33Retroviruses
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’...
01:25Inhibitors Of Virion Release
Viral replication and dissemination rely on efficient mechanisms for host cell entry, genome replication, assembly, and release. Influenza viruses, such as types A and B, are negative-sense single-stranded RNA viruses with a segmented genome, that depend on two critical surface glycoproteins to carry out these processes: hemagglutinin (HA) and neuraminidase (NA). HA initiates infection by binding to sialic acid residues on the surface of host epithelial cells, facilitating receptor-mediated...
01:19Inhibitors of Virion Maturation and Assembly
As part of their replication cycle, certain viruses synthesize long precursor proteins called polyproteins within infected host cells. In human immunodeficiency virus (HIV), two major polyproteins are produced: Gag and Gag-Pol. The Gag polyprotein supplies the structural components of the virus, while Gag-Pol includes essential viral enzymes such as reverse transcriptase, integrase, and protease. After synthesis, these polyproteins move to the host cell membrane, where they assemble into an...
