Fibrogenesis, novel lessons from animal models

Area of Science:

• Immunology
• Rheumatology
• Pathophysiology

Background:

• Systemic sclerosis (SSc) is a chronic autoimmune disease marked by vasculopathy, inflammation, and fibrosis.
• Current understanding suggests an unknown trigger initiates complex interactions leading to persistent tissue fibrogenesis.

Purpose of the Study:

• To review recent findings from animal models of SSc.
• To highlight compounds for clinical trials and new insights into SSc pathophysiology.

Main Methods:

• Review of established and novel animal models for SSc.
• Analysis of data on therapeutic compounds and pathogenetic mechanisms.

Main Results:

• Focus on vessel-extracellular matrix interactions, initial triggers, autoimmunity, and inflammation.
• Exploration of effector cell origins and signaling pathways in fibrogenesis.

Conclusions:

• Animal models are crucial for understanding SSc pathogenesis.
• Recent findings offer new perspectives on SSc mechanisms and potential therapeutic targets.
