Reprogramming Fibrosis: How Protein PTMs Reshape the IPF Proteome

Area of Science:

• Pulmonology and Molecular Biology
• Focuses on cellular and molecular mechanisms underlying lung diseases.

Background:

• Idiopathic pulmonary fibrosis (IPF) is a progressive, fatal lung disease characterized by epithelial damage, inflammation, and aberrant tissue repair.
• Current treatments for IPF do not improve patient survival, highlighting the need for novel therapeutic strategies.

Purpose of the Study:

• To systematically review the role of post-translational modifications (PTMs) in the pathogenesis of IPF.
• To organize PTMs involved in IPF injury stages and analyze their impact on cellular processes and signaling pathways.
• To explore future diagnostic and therapeutic intervention targets for IPF based on PTMs.

Main Methods:

• Systematic literature review of PTMs in the context of IPF.
• Analysis of PTMs' roles in cellular damage, inflammation, and repair processes in IPF.
• Examination of PTMs' influence on cell cycle regulation, energy supply, and signaling pathways like TGF-β.

Main Results:

• PTMs are crucial regulators of cellular functions and signaling pathways implicated in IPF.
• Specific PTMs are involved in different stages of IPF, from initial injury to progressive fibrosis.
• Understanding PTMs offers insights into the roles of various cells in IPF development.

Conclusions:

• Post-translational modifications represent a promising area for understanding IPF pathogenesis.
• Targeting PTMs may offer novel strategies for the clinical diagnosis and treatment of IPF.
• This review provides a framework for future research into PTM-based interventions for IPF.
