Abstract

The percentage of Leu M3⁺DR⁺ and of Leu M3⁺CD25⁺ cells was determined by means of immunofluorescence analysis in a group of patients with insulin dependent diabetes mellitus (IDDM). Our results show that an increased percentage of these cells may occur in the early stage of the disease. These data provide evidence for a “phenotypical” activation of Leu M3⁺ cells at the onset of the disease and warrant future studies to evaluate the potential role of these cells in the pathogenesis of IDDM.
