This review explores pleural mesothelial cells, crucial for pleural space homeostasis. It examines their defense mechanisms and how inflammation, infection, and cancer alter pleural physiology, focusing on cytokine and chemokine networks and fibrosis pathogenesis.
Area of Science:
- Pleural Physiology
- Cell Biology
- Immunology
Background:
- Pleural mesothelial cells are vital for maintaining the pleural space's normal homeostasis.
- These cells are central to the pathophysiology of pleural space disorders.
- Understanding mesothelial cell function is key to addressing pleural diseases.
Purpose of the Study:
- To review the defense mechanisms of pleural mesothelium.
- To examine changes in pleural physiology due to inflammatory, infectious, and malignant conditions.
- To focus on cytokine and chemokine networks in pleural disease pathogenesis.
Main Methods:
- Literature review of scientific articles on pleural mesothelial cells.
- Analysis of studies focusing on inflammatory, infectious, and malignant pleural conditions.
- Examination of research on cytokine and chemokine networks and pleural fibrosis.
Main Results:
- Pleural mesothelial cells possess intrinsic defense mechanisms.
- Inflammatory, infectious, and malignant conditions significantly alter pleural physiology.
- Cytokine and chemokine networks play a critical role in these alterations.
- Pathogenesis of pleural fibrosis involves complex cellular and molecular processes.
Conclusions:
- Pleural mesothelial cells are key players in pleural homeostasis and disease.
- Cytokine and chemokine networks are central to pleural inflammatory responses.
- Further research into these pathways may reveal therapeutic targets for pleural fibrosis.

Pleural Effusion I: Introduction
There are two main types of pleural effusion: transudative and exudative. They are differentiated using Light's criteria,...

Pleural Effusion II: Symptoms and Management
A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.
