Systemic sclerosis & Raynaud's

Multiomics landscape of systemic sclerosis: from autoantibody-positivity to established disease

Ann Rheum DisPublished Mechanistic study

Authors' conclusion

Molecular abnormalities associated with SSc are detectable before overt clinical disease.

Study context

Population
Healthy controls and individuals across the systemic sclerosis (SSc) spectrum from SSc-specific autoantibody-positive (SSAP) through very early diagnosis of SSc (VEDOSS) to established limited and diffuse SSc
Comparison
Healthy controls vs SSAP vs VEDOSS vs limited and diffuse SSc
Outcome
Molecular alterations across the SSc spectrum
Methodological detailsmultiomics, PBMC transcriptomics, plasma proteomics, Connectivity Map analysis

  • PBMC transcriptomics
  • Plasma proteomics
  • Connectivity Map analysis

Main finding

As reported in the abstract

  • Continuous molecular gradient from health to established SSc, with SSAP and VEDOSS in intermediate molecular states
  • Immune dysregulation, particularly innate immune activation and type I interferon signalling, detectable at the SSAP stage, with higher activity across the ordered clinical groups
  • Plasma proteomics identified circulating protein markers related to vascular injury and extracellular matrix remodelling across the clinical groups
  • Connectivity Map (CMap) prioritised JAKi and phosphodiesterase inhibitors as hypothesis-generating perturbagens linked to early disease-associated programmes
