Background: Regulation of virus entry by host lipids is poorly understood. Results: Imaging of low pH-mediated fusion between single vesicular stomatitis pseudoviruses and lipid bilayers revealed a striking reliance on anionic lipids. Conclusion: The dependence of fusion on late endosome-resident anionic lipids suggests a new means for regulating the virus entry sites. Significance: Reliance on specific lipids for fusion may shed light on future antiviral strategies.
