Abstract

A number of air pollutants is known to affect the immune system resulting in alterations of the complement activity in serum. We determined the levels of C3c, one of the activation products of the component C3, in serum samples obtained from various population groups living in areas with different levels of air pollution in Northrhine-Westphalia (FRG). The results show that the serum C3c levels tend to be increased in subjects living in areas with elevated levels of air pollution. By applying a linear regression model it can be demonstrated that a significant part of the variance of the C3c concentrations is explained by the residence area factor after making allowance for the effect of various confounders. The increase of the serum C3c concentrations appears to result from an increased activation of the complement component C3. The underlying mechanisms as well as the pathophysiological significance of these findings are unknown.
