Area of Science:

  • Immunology
  • Rheumatology
  • Pathophysiology

Context:

  • Systemic sclerosis (SSc) is a complex connective tissue disease.
  • It is marked by vascular dysfunction and progressive fibrosis affecting skin and internal organs.
  • Immune system activation is a key factor in SSc pathogenesis.

Purpose:

  • To review the role of immune system activation in systemic sclerosis.
  • To describe abnormalities in endothelial cells, T cells, B cells, and fibroblasts in SSc patients.

Summary:

  • Immune mechanisms contribute to SSc through auto-antibodies, inflammatory infiltration, and immune cell activation.
  • Activated immune cells release cytokines that promote fibroblast proliferation and collagen production.
  • Immune activation also impairs endothelial function, causing SSc-typical angiopathy and tissue ischemia.

Impact:

  • Understanding these immune abnormalities is crucial for developing targeted therapies for systemic sclerosis.
  • This review highlights the intricate interplay between immune cells, fibroblasts, and vascular endothelium in SSc.
  • Identifying specific cellular dysfunctions may lead to novel diagnostic and therapeutic strategies for SSc.
