Japanese encephalitis virus invasion of cell: allies and alleys

Area of Science:

• Virology
• Neuroscience
• Public Health

Background:

• Japanese encephalitis virus (JEV) is a mosquito-borne flavivirus and the leading cause of viral encephalitis worldwide.
• JEV infection presents a spectrum of illness, from mild fever to severe neurological disease and death, posing a significant public health threat.
• Understanding JEV's cellular entry mechanisms is critical for developing antiviral therapies.

Purpose of the Study:

• To provide a comprehensive review of JEV's attachment and receptor interactions (allies).
• To elucidate the endocytic pathways (alleys) utilized by JEV for cellular entry.
• To discuss unresolved issues and compare JEV entry mechanisms with other flaviviruses.

Main Methods:

• Literature review of existing research on JEV.
• Analysis of studies investigating JEV-host cell interactions.
• Comparative analysis of JEV and other flavivirus entry pathways.

Main Results:

• JEV infects multiple cell types, but its primary receptor(s) remain unidentified.
• JEV employs diverse endocytic pathways for cell entry.
• Key differences and similarities exist between JEV and other flaviviruses regarding cell entry.

Conclusions:

• Identifying JEV receptors and entry pathways is crucial for therapeutic intervention.
• Further research is needed to fully understand JEV's complex cell entry mechanisms.
• Comparative studies enhance our understanding of flavivirus tropism and pathogenesis.
