Clara cell 10 kilodalton protein(CC10) is the major product of non-ciliated bronchiolar epithelial cells (Clara cells) and is identical with uteroglobin and urinary protein 1(P-1). CC10/uteroglobin is a homodimer consisting of 70 amino acid subunits arranged in an antiparallel fashion and connected by two disulfide bonds. CC10/uteroglobin shows an anti-inflammatory property including inhibition of phospholipase A2 and phospholipase C. We analyzed the epitope of monoclonal antibodies(mAbs) to human CC10/P-1. TY-5, TY-7 and TY-8 recognized alpha 1-, alpha 2- and alpha 3-helix of CC10, respectively. The combination of TY-1 and TY-2 are most suitable for ELISA, while TY-5 and TY-7 are very good for immunoblot and immunohistochemical analysis. Circulating CC10 levels are increased in sarcoidosis and decreased in asthma. Bronchoalveolar lavage CC10 levels are increased in sarcoidosis patients with a good outcome. The use of these mAbs is a powerful tool to investigate the clinical roles of CC10. CC10 is a regulator of the inflammatory process in respiratory diseases.

Pulmonary involvement occurs in up to 95% of sarcoidosis cases. In this pilot study, we examine lung compartment-specific protein expression to identify pathways linked to development and progression of pulmonary sarcoidosis. We characterized bronchoalveolar lavage (BAL) cells and fluid (BALF) proteins in recently diagnosed sarcoidosis cases. We identified 4,306 proteins in BAL cells, of which 272 proteins were differentially expressed in sarcoidosis compared to controls. These proteins map to novel pathways such as integrin-linked kinase and IL-8 signaling and previously implicated pathways in sarcoidosis, including phagosome maturation, clathrin-mediated endocytic signaling and redox balance. In the BALF, the differentially expressed proteins map to several pathways identified in the BAL cells. The differentially expressed BALF proteins also map to aryl hydrocarbon signaling, communication between innate and adaptive immune response, integrin, PTEN and phospholipase C signaling, serotonin and tryptophan metabolism, autophagy, and B cell receptor signaling. Additional pathways that were different between progressive and non-progressive sarcoidosis in the BALF included CD28 signaling and PFKFB4 signaling. Our studies demonstrate the power of contemporary proteomics to reveal novel mechanisms operational in sarcoidosis. Application of our workflows in well-phenotyped large cohorts maybe beneficial to identify biomarkers for diagnosis and prognosis and therapeutically tenable molecular mechanisms.
