Summary

Human Club cell protein (CC16, CC10, uteroglobin, urinary protein 1 or Clara cell secretory
protein) is a member of the secretoglobin family of proteins and is a secreted product of nonciliated
bronchiolar Club cells. Its function remains to be fully elucidated but there is
convincing data suggesting its role as an immune-modulating and anti-inflammatory agent.
Club cell protein inhibits phospholipase A2 activity as well as interferon gamma signaling and
Th1 vs. Th2 lymphocyte regulation.

Club cell protein concentrations have been determined in serum, plasma and bronchoalveolar
lavage fluid in numerous studies since 1994. In serum, its increase is associated with age and
asbestos, nitrogen chloride and ozone exposure. Higher levels of CC16 were demonstrated in
patients with sarcoidosis, pulmonary fibrosis and high PEEP ventilation. Decreased serum
CC16 levels are found after pulmonary resection in smokers and in subjects with chronic
obstructive pulmonary disease, asthma or silica exposure.

Decreased CC16 concentrations were also found in the amniotic fluid of fetuses suffering from
pulmonary hypoplasia caused by various mechanisms (diaphragmatic hernia, diabetic
fetopathy, Turner and Down syndrome). In pleural effusions, the CC16 concentration appears
to be associated with its diffusion from the lung as evidenced by high CC16 levels in cardiac
pleural congestion.
Based on the above reports Club cell protein might be perspective useful diagnostic marker of
pulmonary diseases and injuries.
