title: Dissociated production of interleukin-2 and immune gamma-interferon by phytohaemoagglutinin stimulated peripheral mononuclear cells in type 1 (insulin-dependent) diabetes.
abstract: In order to analyze the first steps of T cell activation in type 1 diabetes we studied in vitro IL-2 and gamma-IFN production by peripheral blood mononuclear cells after 24 h PHA stimulation. There was a significant decrease in IL-2 production by mononuclear cells of the diabetic patients with respect to the controls. No significant difference was observed between the diabetic patients and the healthy subjects as regards gamma-IFN production. These observations may be interesting in relation to the pathogenetic mechanisms involved in type 1 diabetes. In particular, normal gamma-IFN production may indicate integrity of the natural killer circuit.
