Systemic sclerosis-associated fibrosis: an accelerated aging phenotype?

Area of Science:

• Immunology
• Geroscience
• Rheumatology

Background:

• Systemic sclerosis (SSc) is an autoimmune disease characterized by multi-organ fibrosis.
• SSc-associated fibrosis exhibits similarities to age-related fibrotic disorders.
• The role of aging in SSc development is increasingly recognized.

Purpose of the Study:

• To review the current literature on the potential role of aging and age-related cellular processes in SSc.
• To explore the connection between aging mechanisms and fibrosis in systemic sclerosis.

Main Methods:

• Literature review of current research on aging and SSc.
• Analysis of cellular processes implicated in both aging and SSc fibrosis.

Main Results:

• Evidence suggests immune dysregulation, epigenetic modifications, cellular senescence, mitochondrial dysfunction, and impaired autophagy contribute to fibrosis in aging and SSc.
• These age-related cellular alterations are implicated in the development and progression of SSc-associated fibrosis.

Conclusions:

• Cellular alterations associated with aging may play a significant role in the pathogenesis and advancement of SSc-associated fibrosis.
• Further research into these age-related mechanisms could offer new therapeutic targets for SSc.
