Zika virus (ZIKV) infection increases host cell contractility. Reducing this contractility, through drug or matrix changes, impairs ZIKV infection, replication, and production.
Area of Science:
- Virology
- Cell Biology
- Biophysics
Background:
- Emerging infectious diseases, like Zika virus (ZIKV), present significant global health challenges.
- The influence of host cell mechanobiology on ZIKV pathogenesis remains poorly understood.
Purpose of the Study:
- To investigate the role of host cell contractility in ZIKV infection dynamics.
- To determine if manipulating host cell contractility affects viral infection efficacy.
Main Methods:
- Utilized drug perturbation and gene editing to alter intracellular actomyosin function.
- Employed compliant extracellular matrices to modulate host cell contractility.
- Assessed ZIKV infection efficiency, viral genome replication, and particle production.
Main Results:
- ZIKV infection was observed to increase host cell contractility.
- Disrupting actomyosin function significantly reduced ZIKV infection, replication, and viral particle release.
- Culturing cells on softer substrates, which decreased contractility, also compromised ZIKV infection.
Conclusions:
- Host cell contractility is positively correlated with ZIKV infection efficacy.
- Mechanobiological properties of host cells represent a novel factor in ZIKV-host interactions.
- Targeting host cell contractility may offer new strategies for controlling ZIKV infections.
