title: Altered interleukin-2 production in schizophrenia: association between clinical state and autoantibody production.
abstract: Mitogen-stimulated interleukin-2 (IL-2) production was measured in 122 patients who met Research Diagnostic Criteria for schizophrenia and 98 normal control subjects. The presence of autoantibodies against seven common antigens was also determined. There was no relationship between the presence of circulating autoantibodies and IL-2 production in control subjects. In patients, however, autoantibody-positive, acutely ill patients had significantly lower IL-2 production as compared with other patients and control subjects. Never-medicated patients showed the same trends for decreased IL-2 production in association with autoantibodies. These data suggest that decreased IL-2 production is associated with acute illness in schizophrenic patients who produce autoantibodies, a trait known to be associated with increased vulnerability to autoimmune disease.
