Overview
This article describes a method for implanting glass windows over the exposed spinal cords of adult mice to study experimental autoimmune encephalomyelitis (EAE). The technique allows for chronic optical access to monitor cell dynamics at the subcellular level using two-photon microscopy.
Key Study Components
Area of Science
- Neuroscience
- Immunology
- Microscopy
Background
- Experimental autoimmune encephalomyelitis is a model for studying multiple sclerosis.
- Two-photon microscopy enables high-resolution imaging of live tissues.
- Chronic imaging techniques are essential for understanding disease progression.

- To observe spatiotemporal changes in cell distributions and interactions.
Methods Used
- Implantation of a spinal clamp to support the vertebrae.
- Exposure of the spinal cord and preparation of vertebrae edges.
- Implantation of a glass window with silicone elastomer.
- Induction of EAE several weeks post-implantation.
Main Results

What is experimental autoimmune encephalomyelitis?
EAE is an animal model used to study multiple sclerosis and autoimmune responses in the central nervous system.
How does two-photon microscopy work?
Two-photon microscopy uses infrared light to excite fluorescent molecules, allowing for deep tissue imaging with minimal damage.
What are the benefits of using glass windows in this study?
Glass windows provide chronic access to the spinal cord, enabling long-term observation of cellular dynamics and interactions.
What role does silicone elastomer play in the implantation?
Silicone elastomer acts as a cushion between the glass window and the dura, preventing damage and ensuring stability.
Can this method be applied to other models of disease?
Yes, the technique can potentially be adapted for other models requiring chronic imaging of the spinal cord or other tissues.
What are the implications of this research?
This research enhances our understanding of autoimmune diseases and could lead to better therapeutic strategies.
