Highlights from the breakout session: transcriptomic approaches to the study of systemic vasculitis

Area of Science:

• Immunology
• Molecular Biology
• Genomics

Background:

• Understanding the molecular pathogenesis of immune-mediated systemic vasculitis is essential for developing targeted therapies and biomarkers.
• Current candidate approaches and bulk transcriptional profiling have limitations in identifying novel therapeutic targets and capturing cellular heterogeneity in inflamed tissues.

Purpose of the Study:

• To highlight the advancements in multi-dimensional molecular profiling techniques for studying systemic vasculitis.
• To emphasize the potential of single-cell and spatial transcriptomics/proteomics in revealing the molecular underpinnings of vasculitis.

Main Methods:

• Review of recent advances in experimental techniques and analytical tools for molecular profiling.
• Application of single-cell and spatial resolution techniques to interrogate the transcriptome and proteome.
• Discussion of findings presented at the 21st International Vasculitis Workshop's breakout session on transcriptomic approaches.

Main Results:

• Multi-dimensional molecular profiling enables a deeper understanding of molecular pathogenesis than traditional methods.
• Single-cell and spatial profiling can capture cellular composition differences and changes within inflamed vascular tissue.
• These advanced techniques are crucial for identifying novel therapeutic targets and biomarkers for systemic vasculitis.

Conclusions:

• Recent technological advances in molecular profiling are revolutionizing the study of systemic vasculitis.
• Single-cell and spatial transcriptomics/proteomics provide unprecedented resolution for understanding disease mechanisms.
• These approaches hold significant promise for the development of more effective targeted therapies and biomarkers.
