Cross-disease immune cells atlas reveals the similarities and differences of cell characteristics and interactions in rheumatic diseases
To systematically characterize the similarities and differences in immune cells among various rheumatic diseases, including rheumatoid arthritis, systemic lupus erythematosus, and others, as well as healthy controls using single-cell RNA sequencing data.
Key Findings:
Common immune dysregulation modules were identified across rheumatic diseases, particularly impaired function of γδ T cells, which may contribute to disease pathology.
MIF and GALECTIN signaling pathways were crucial for interactions between T cells and myeloid cells, suggesting potential therapeutic targets.
Specific disease characteristics were retained, such as enhanced cytotoxicity in myeloid cells of Behçet’s disease and active inflammatory states in systemic lupus erythematosus, indicating the need for tailored interventions.
Interpretation:
The study reveals both shared and specific immune dysregulation patterns across rheumatic diseases, enhancing understanding of their immune mechanisms and identifying potential therapeutic targets for intervention.
Limitations:
The analysis may be affected by inherent heterogeneity in sample processing and sequencing depth across datasets, which could influence the reliability of the findings.
Focus on peripheral blood mononuclear cells may not capture all relevant immune interactions occurring in tissues, potentially overlooking critical aspects of disease pathology.
Conclusion:
This research provides a comprehensive immune cell atlas that could inform future precision immune intervention strategies for rheumatic diseases.
