Objective:

To characterize the transcriptional heterogeneity and inflammatory response of Müller glia in the retinas of STZ-induced diabetic mice using single-cell RNA sequencing, highlighting the significance of this understanding in diabetic retinopathy.

Approach:

Key Findings:

• Identified four distinct Müller glial subpopulations with significant transcriptional perturbation in diabetic conditions, with implications for understanding their role in inflammation.
• Müller glia showed the strongest transcriptional response among retinal cell types under diabetic stress.
• Pseudotime analysis indicated branch-dependent transcriptional programs among Müller subclusters.
• Functional enrichment analysis linked different Müller glial subclusters to distinct biological processes and highlighted Cebpb as an inflammation-associated factor.
• Co-expression network analysis revealed Müller glia-associated gene modules with varying activity patterns.

Interpretation:

Müller glia play an active role in diabetic retinal remodeling, exhibiting transcriptional heterogeneity and involvement in inflammatory, structural, and neuron-interactive processes.

Limitations:

• The study relies on reanalysis of existing datasets, which may limit the scope of findings due to potential variability in scRNA-seq data quality and interpretation.

Conclusion:

The findings provide insights into Müller glial dysfunction in diabetic retinopathy, supporting further investigation into their role in disease pathology and potential therapeutic strategies.
