Abstract

We have previously suggested that anti-DNA antibodies present in systemic lupus erythematosus patients can bind directly to tissues as a result of cross-reactivity with embryonal tissue-based antigens. Here we have analyzed the interaction between polyclonal and monoclonal mouse and human lupus autoantibodies and an embryonal cell line. We report that a murine embryonal stem cell line (ES) expresses a surface antigen which is recognized by mouse and human lupus autoantibodies. This surface antigen is down-regulated following maturation of the cells or incubation with corticosteroids. Adhesion molecules may serve as the target membrane antigen in ES cells since preincubation with these antibodies decreases the ability of ES cells to adhere to the plate.
