Insights
This study introduces a new method for analyzing immune cells in separated corneal layers. This technique improves the distinction between immune cells in the corneal epithelium and stroma during herpes simplex virus-1 infection.
Area of Science:
- Ophthalmology
- Immunology
- Virology
Background:
- Current flow cytometry methods analyze whole corneas, hindering precise immune cell localization.
- Distinguishing immune cell infiltration in the corneal epithelium versus stroma is crucial for understanding ocular inflammation.
Purpose of the Study:
- To develop and present a protocol for analyzing immune cells in separated corneal epithelium and stroma.
- To enable detailed investigation of immune responses in distinct corneal layers during herpes simplex virus-1 (HSV-1) infection.
Main Methods:
- Detailed protocol for herpes simplex virus-1 (HSV-1) infection in mouse models.
- Method for separating the corneal epithelium from the corneal stroma.
- Single-cell suspension preparation from isolated epithelial and stromal tissues.
- Flow cytometry assay for immune cell analysis in separated layers.
Main Results:
- Successful separation of corneal epithelium and stroma.
- Generation of single-cell suspensions from both layers.
- Enables distinct immune cell profiling in epithelial and stromal compartments.
Conclusions:
- The presented protocol allows for precise analysis of immune cells in the corneal epithelium and stroma.
- This method enhances the understanding of immune cell dynamics in ocular infections like HSV-1.
- Facilitates targeted research into localized immune responses within the cornea.
Abstract:
Existing flow cytometry approaches identify immune cells using the whole infected/inflamed cornea, which limits its ability to distinguish the immune cells infiltrating the corneal epithelium from the corneal stroma. Here, we present a protocol to analyze immune cells in the separated epithelium and stroma from naïve and herpes simplex virus-1 (HSV-1)-infected mouse corneas. We describe steps for viral infection, separation of corneal epithelium from stroma, preparation of a single-cell suspension of the individual epithelium and stroma, and flow cytometry assay.
