Between life and death: Epithelial cells in lung pathologies

Area of Science:

• Pulmonary medicine
• Cell biology
• Molecular mechanisms

Background:

• Recent advances in lineage tracing, single-cell RNA sequencing, and high-resolution imaging reveal significant heterogeneity among lung epithelial cells.
• This heterogeneity raises questions about the specific roles of these cells in maintaining lung health and during disease progression.

Discussion:

• Understanding the molecular control of lung epithelial cell morphogenesis and differentiation is key.
• Investigating cell-cell and cell-extracellular matrix communication is vital for improving patient outcomes in respiratory diseases.

Key Insights:

• Despite progress, precise control over lung epithelial cells for repair and regeneration remains a challenge.
• The structural and functional diversity of lung epithelial cells in both healthy and pathological states is a critical area of study.

Outlook:

• This special issue compiles research and reviews on lung epithelial cell diversity in pathology.
• Future work will focus on harnessing this knowledge for therapeutic strategies in lung diseases.
