Summary
Ribavirin demonstrates effectiveness in inhibiting Enterovirus 71 (EV71) replication and inactivating the virus in vitro. This antiviral agent also provides protection to RD-A cells against EV71 infection, aiding in disease control.
Area of Science:
- Virology
- Antiviral Research
- Cell Biology
Context:
- Enterovirus 71 (EV71) is a significant pathogen causing Hand, Foot, and Mouth Disease (HFMD).
- EV71 outbreaks necessitate effective therapeutic interventions.
- The Anhui Fuyang HFMD outbreak provided the source for the EV71 strain used in this study.
Purpose:
- To evaluate the in vitro efficacy of Ribavirin against EV71.
- To determine Ribavirin's ability to inhibit EV71 replication.
- To assess Ribavirin's antiviral activity, including viral inactivation and cell protection.
Summary:
- Ribavirin treatment, at dilutions such as 1:640, delayed the onset of Cytopathic Effect (CPE) by 2 days, indicating inhibition of EV71 replication.
- A 1:8 dilution of Ribavirin extended the delay of CPE to 4 days, demonstrating significant protection of RD-A cells from EV71 infection.
- Ribavirin at a 1:40 dilution also showed antiviral effects by delaying CPE by 2 days, suggesting viral inactivation capabilities.
Impact:
- The findings support Ribavirin as a potential therapeutic agent for EV71 infections.
- This research contributes to the development of strategies for controlling EV71 outbreaks.
- The study provides a basis for rapid therapeutic interventions against EV71.

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...
01:30Inhibitors of Viral Protein Synthesis
Protein synthesis is indispensable for viral replication, as viruses lack the cellular machinery required for this process and must hijack the host's translational apparatus. In response, host cells deploy a critical innate immune defense involving interferons, specialized cytokines that play a central role in inhibiting viral propagation.Upon viral detection, infected cells release interferons that bind to receptors on adjacent uninfected cells, activating the JAK-STAT signaling pathway and...
01:16In vitro Mutagenesis
To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.
