RESUMO
The ability of the reticuloendothelial system (RES) to bind and catabolize soluble stable heat aggregates of 125I-IgG (A-IgG) was studied in mice given oral cadmium. Cadmium caused a delay in the circulation clearance of A-IgG in intact animals. The defect was due to impaired liver uptake of A-IgG and correlated with increased liver cadmium. Subsequent catabolism of bound A-IgG by liver slices was not affected. The defect was specific in that clearance of aggregated human serum albumin and colloidal carbon was normal in cadmium mice; this suggests that cadmium may affect either Fc or complement receptors of Kupffer cells in liver.
