Abstract: The Clara cell 16 kD protein (CC16), the predominant product of the Clara cells lining the bronchiolar epithelium, is thought to protect the respiratory and urogenital tract from unwanted inflammatory reactions through its immunosuppressive action. In this report, we show evidence that CC16 establishes an anti-inflammatory activity by interfering with the interferon-gamma (IFN-gamma)-mediated actions of the cytokine network. The HuIFN-gamma production of stimulated single-donor peripheral blood mononuclear cells is inhibited by the presence of doses of CC16 in the range of 10(-12) M, with a maximal inhibition (up to 95%) when interleukin-2 is used as a stimulating agent. CC16 also diminishes the biologic activity of IFN-gamma: both the antiviral activity and the stimulation of phagocytosis by IFN-gamma, measured by means of chemiluminescence, are reduced in the presence of CC16. These observations indicate that CC16 acts as an anticytokine and could give new insight in the potential role of the Clara cells.
