Why the study?

How enterovirus particles or RNA genomes cross the endosome membrane into the host cell cytoplasm remains unknown.

Population

Cells infected with rhinovirus 2, echovirus 18, echovirus 30, or enterovirus 71, and uninfected cells

Comparison

Inhibition with bafilomycin A1 or wiskostatin vs untreated cells

Design

Cryo-electron tomography study

Overview

Hypothesis-generating for enterovirus entry; leaves open mechanisms for non-enveloped virus infection.

Structured PICO

P
Population
Cells infected with enteroviruses (rhinovirus 2, echovirus 18, echovirus 30, or enterovirus 71)
I
Intervention
Cryo-electron tomography observation; treatment with bafilomycin A1 or wiskostatin
O
Outcome
Mechanism of enterovirus genome release into the cytoplasm

Enteroviruses enter the host cell cytoplasm via cell-mediated endosome disruption, a mechanism that may be common across many enteroviruses.
