title: Characterization of cell surface antigens on the adrenergic neuroblastoma clone A2(1).
abstract: Neuroblastoma cell lines have been extensively used to identify the presence of brain reactive autoantibodies in the sera of patients with systemic lupus erythematosus (SLE) who have neuropsychiatric involvement and in the animal models (murine) of this disorder. In this study, a characterization of murine neuroblastoma cell surface antigens, from the adrenergic A2(1) cell line, have indicated both similarities and differences with the cell surface antigens of normal mouse brain. It has also shown that some of these antigens are nervous system specific, whereas others are not. These data indicate that a more precise definition of the antigens on the surface of neuroblastoma cells, with which anti-brain autoantibodies react, is necessary for an understanding of the neuropsychiatric manifestations associated with autoimmune diseases such as SLE.
