KL-6, Surfactant Protein A and D in Bronchoalveolar Lavage Fluid from Patients with Pulmonary Sarcoidosis

Abstract

We conclude that KL-6 and SP-D levels in BALF were increased in pulmonary sarcoidosis. Since these markers are specifically derived from epithelial cells, it is considered that KL-6 and SP-D levels are reflecting damage or release of these markers from epithelial cells due to the inflammatory response.
