Summary
Human enterovirus 71 (EV71) demonstrates resistance to the antiviral effects of type I interferons. This study found EV71 effectively replicates in cells treated with interferon, unlike herpes simplex virus 1.
Area of Science:
- Virology
- Immunology
Context:
- Type I interferons (IFN-α, IFN-β) are crucial for innate antiviral immunity.
- Enterovirus 71 (EV71) is a significant human pathogen.
- Understanding viral resistance mechanisms to interferon is vital for therapeutic development.
Purpose:
- To investigate the resistance of human enterovirus 71 (EV71) to type I interferon-induced antiviral effects.
- To compare the susceptibility of EV71 and herpes simplex virus 1 (HSV-1) to interferon treatment in cell culture.
Summary:
- HeLa cells treated with type I interferons showed inhibited herpes simplex virus 1 (HSV-1) replication, as evidenced by reduced GFP expression and viral DNA.
- In contrast, human enterovirus 71 (EV71) effectively replicated in interferon-treated HeLa cells, indicating resistance to the induced antiviral state.
- This suggests EV71 possesses mechanisms to counteract type I interferon-mediated antiviral responses.
Impact:
- Highlights EV71's ability to evade a key host antiviral defense mechanism.
- Provides insights into viral immune evasion strategies.
- May inform the development of novel antiviral therapies targeting EV71.

Arboviral Encephalitis
Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...
Inhibitors 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...
Cytomegalovirus Disease
Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
