Abstract

Searching for the cause of the known immunological abnormalities in systemic lupus erythematosus (SLE), the density of cell surface antigens was measured after immunofluorescent staining in a cell sorter. The densities of CD3, CD4, CD5, CD8 and sIgM lymphocyte antigens were the same on patients' lymphocytes as on lymphocytes from healthy subjects. The intensity of HLA-DR immunofluorescence was found to be decreased on patients' monocytes, while the expression of HLA-DR on lymphocytes of patients with SLE hardly differed from that in healthy subjects. Pretreatment of normal mononuclear cells with patients' sera free from immune complexes decreased the binding of anti-HLA-DR antibody to normal monocytes, but it hardly caused alteration on lymphocytes. After culturing, the expression of HLA-DR antigen on patients' monocytes became the same as on normal cells. A causal role of anti-HLA-DR autoantibodies is suggested and discussed.
