Abstract
Clara cells localized in the bronchiole are thought to play a key role in lung remodeling. Clara cell secretory protein (CCSP), which is specifically produced by Clara cells, inhibits pro-inflammatory cytokines and chemotaxis of fibroblasts, and acts as phospholopase A2 inhibitors, and may also inhibit inflammation and fibrosis in the lung. This could be a biomarker of interstitial pneumonitis. Proliferation of Clara cells and neuroendocrine cells at airway epithelial injury may act as progenitor cells during the repair process.
