Area of Science:

  • Rheumatology
  • Immunology
  • Pathology

Background:

  • Systemic sclerosis (SSc) is a complex multisystem disease with immunological abnormalities, vasculopathy, and fibrosis.
  • Existing animal models partially represent SSc, but none fully capture its clinical picture, impeding therapeutic development.

Purpose of the Study:

  • To review recent advancements in SSc animal models.
  • To identify novel therapeutic targets for SSc based on insights from these models.

Main Methods:

  • Review of recent inducible and genetic animal models of SSc.
  • Analysis of pathological processes including fibrosis and vasculopathy.

Main Results:

  • Inducible models highlight the roles of reactive oxygen species, angiotensin II, and DNA topoisomerase I/IL-6 in SSc fibrosis.
