    Abstract

    The receptor for DNA was functionally defective in the majority of patients with systemic lupus erythematosus (SLE; 91% of 35 studied) and allied rheumatic disorders. This functional defect was manifest by impaired binding of exogenous DNA to the cell surface of peripheral blood mononuclear cells and an inability of cells to internalise and degrade DNA. The receptor defect was not constitutive, since it could be reversed by overnight incubation of cells; this process was sensitive to cycloheximide, suggesting a requirement for active receptor regeneration. The DNA-receptor defect could be induced in healthy controls, by incubating their cells with the serum of patients with SLE. The humoral factor inducing the defect was an autoantibody.
