Decreased activity of interleukin-2 inhibitor in plasma of patients with systemic lupus erythematosus

Abstract
Low levels of plasma interleukin-2 inhibitory activity were found in patients with systemic lupus erythematosus (SLE) compared to normal individuals. The depression of the inhibitory activity was significant in patients with severe and moderate SLE while only a slight decrease was observed in the mild form of the disease.
