Published Workflows

Visualizing Viral Infection In Vivo by Multi-Photon Intravital Microscopy

2018

Objective: Study viral infection, dissemination, pathogenesis, and host immune responses in living organisms by real-time in vivo imaging, while extending interpretability through complementary perturbation and molecular analysis.

Why it works: The review frames MP-IVM as enabling real-time observation of infection processes under physiological conditions, with animal preparation and fluorescent labeling providing access and signal, and optogenetic or transcriptional additions extending the significance of the imaging results.

Stages

1.
Microsurgical animal preparation(library_build)
The abstract explicitly notes experimental challenges during microsurgical animal preparation, indicating this is a prerequisite stage for in vivo intravital imaging.
Selection: Preparation of living animals for intravital imaging access
2.
Fluorescent labeling for intravital imaging(library_design)
Fluorescent labeling strategies are discussed because MP-IVM relies on multi-photon excitation of fluorophores and direct visualization of fluorescent virus particles or infected cells.
Selection: Establish fluorescently visible targets for intravital imaging
3.
In vivo multi-photon intravital imaging(functional_characterization)
This is the core stage that enables observation of viral infection processes in living organisms.
Selection: Real-time observation of virus dissemination, pathogenesis, and immune responses under physiological conditions
4.
Complementary optogenetic and transcriptional integration(secondary_characterization)
The review explicitly highlights combining MP-IVM with optogenetic tools and transcriptional analysis as a powerful way to extend the significance of imaging studies.
Selection: Extend the significance of in vivo imaging studies
