these data strongly suggest that the abnormality of murine strains with systemic lupus erythematosus causing them to produce antibodies to their own xenotropic viral gp70 and to form ic with serum gp70 is not based on their expression of an unusual type of gp70 , but rather their ability to make an antibody to nzb-x1 gp70 , probably as a result of their immunologic dysfunction .
