Insights into interstitial lung disease pathogenesis

Area of Science:

• Translational science
• Pulmonary medicine
• Immunology

Background:

• Interstitial lung diseases (ILDs) are complex, influenced by genetic and environmental factors.
• Fibroblasts and specific macrophage subtypes (M2) are central to ILD pathogenesis, driving fibrosis.
• Chronic type 2 immunity plays a role in ILD-related fibrosis.

Purpose of the Study:

• To review key features of ILDs from a translational science perspective.
• To explore potential therapeutic targets and strategies for ILDs.
• To highlight the importance of personalized management in ILDs.

Main Methods:

• Literature review focusing on translational aspects of ILDs.
• Analysis of the roles of fibroblasts, macrophages, and immune responses in ILD.
• Evaluation of current and potential biomarkers and animal models for ILD research.

Main Results:

• Genetic and environmental factors significantly impact ILD onset, progression, and treatment response.
• Fibroblasts and M2 macrophages are critical drivers of fibrosis, representing therapeutic targets.
• Serum biomarkers (KL-6, SFTP-D, MMP-7, CCL-18) show diagnostic and prognostic value, requiring further clinical validation.
• Animal models provide insights but require careful selection and validation for translational relevance.

Conclusions:

• Personalized management strategies are essential for ILDs.
• Targeting fibroblasts, macrophages, and immune responses offers promising therapeutic avenues.
• Further research is needed to translate preclinical findings and biomarkers into effective clinical applications for ILDs.
