title: [Circulating immune complexes and NK activity in systemic lupus erythematosus].
abstract: NK-activity of normal mononuclear cells is inhibited in vitro by addition of immune complexes or aggregated IgG. We therefore studied 20 sera of patients with systemic lupus erythematosus in order to investigate whether there is any correlation between the presence of circulating immune complexes and suppression of NK-activity. A correlation was not found.
