Band keratopathy in MRL/l and MRL/n mice
Abstract:
To define ocular abnormalities in mice with autoimmune disease, we performed biomicroscopic examinations and examined ocular tissue in MRL/l, MRL/n, NZB, NZB/NZW, and Palmerston North mice. Results were compared with MRL/Mp--lpr/lpr, C57BL/6J--lpr/lpr, and normal control strains. Eighty-seven percent of MRL/l and MRL/n mice had typical band keratopathy; this was confirmed by histologic examination. Posterior uveitis was found in 35% of adult MRL/l mice. MRL substrains are potentially important models of ocular disease.
Insights
Mice with autoimmune disease commonly develop ocular abnormalities like band keratopathy and posterior uveitis. Specific MRL substrains show high prevalence, indicating their potential as models for studying eye diseases.
Area of Science:
- Immunology
- Ophthalmology
- Genetics
Background:
- Autoimmune diseases can affect various organs, including the eyes.
- Murine models are crucial for understanding human autoimmune conditions and their complications.
- Ocular manifestations in autoimmune mouse strains require detailed characterization.
Purpose of the Study:
- To identify and characterize ocular abnormalities in specific mouse strains with autoimmune disease.
- To evaluate the prevalence of eye conditions in MRL/l, MRL/n, NZB, NZB/NZW, and Palmerston North mice.
- To assess the suitability of MRL substrains as models for ocular autoimmune disease.
Main Methods:
- Biomicroscopic examinations of eyes in different mouse strains.
- Histologic examination of ocular tissues to confirm findings.
- Comparative analysis with control strains (MRL/Mp--lpr/lpr, C57BL/6J--lpr/lpr) and normal mice.
Main Results:
- Eighty-seven percent of MRL/l and MRL/n mice exhibited characteristic band keratopathy.
- Histologic examination confirmed the presence of band keratopathy.
- Posterior uveitis was observed in 35% of adult MRL/l mice.
Conclusions:
- MRL/l and MRL/n mice display significant ocular abnormalities, including band keratopathy and uveitis.
- These MRL substrains represent valuable models for investigating ocular pathologies associated with autoimmune diseases.
- Further research using these models can elucidate disease mechanisms and therapeutic strategies.
