    Progressive systemic sclerosis (PSS) involves immune system abnormalities, vascular issues, and fibrosis. Understanding its complex mechanisms, including endothelial and fibroblast dysfunction, is key to developing new treatments for this autoimmune disorder.

    Area of Science:

    • Immunology
    • Pathophysiology
    • Rheumatology

    Context:

    • Progressive systemic sclerosis (PSS) is a complex autoimmune disease of unknown etiology.
    • Characterized by immune dysregulation, microvascular damage, and excessive fibrosis in skin and internal organs.
    • Current understanding highlights neuropeptides, vascular endothelium, and fibroblast dysfunction as key contributors to fibrosis.

    Purpose:

    • To review recent findings on the pathophysiological mechanisms of PSS.
    • To elucidate the roles of adhesion molecules, immune reactions, and fibroblast biology in vascular and connective tissue alterations.
    • To emphasize the need for deeper knowledge for novel therapeutic strategies.

    Summary:

    • PSS pathogenesis involves immunological abnormalities, endothelial dysfunction, and fibroblast dysregulation.

  • Cytokine cascades (e.g., IL-1, TGF-beta-1) link endothelial and fibroblast dysfunction.
  • Raynaud's phenomenon exemplifies the vasospastic tendency in systemic sclerosis.

    • Impact:

    • Advances understanding of scleroderma's complex pathophysiology.
    • Identifies key molecular and cellular players in disease progression.
    • Provides a foundation for developing targeted therapies for PSS.
