Hypothesis
To study the phenotypes, distribution, and morphologies of different antigen-presenting cells (APCs) in the murine cornea.
Conclusion
Intravitreal injection of labeled antibodies can be adapted to visualize labeled cells in the cornea, revealing distinct morphologies and distributions of APCs.
Supporting Evidence
- Histological examination revealed no observable change in the cornea following intravitreal injection.
- Two populations with distinct morphological features were identified among these APCs.
- Labeled cells were found beneath the epithelium or in the shallow stroma in the central and paracentral cornea.
Takeaway
The study looked at special immune cells in the eye called antigen-presenting cells and found that they are spread out in different ways in the cornea, which helps the eye stay healthy.
Methodology
The study used intravitreal injection of fluorescently tagged ovalbumin and antibodies, followed by various microscopy techniques to examine the corneal cells.
Limitations
The study was conducted on a specific mouse strain, which may limit the generalizability of the findings to other species.
Participant Demographics
Female BALB/c mice, 6-8 weeks of age, weighing 20-26 g.
