    Notes: Abstract Aims/hypothesis. Type I (insulin-dependent) diabetes results mainly from T-cell-mediated autoimmune destruction of pancreatic beta cells. Cytotoxic T lymphocytes destroy target cells via a perforin-based or Fas-based mechanism. Our previous study indicated that the Fas-Fas ligand (FasL) pathway is required for the development of autoimmune diabetes in the NOD mouse. We now investigated whether or not the Fas-FasL system is involved in the beta-cell destruction in human Type I diabetes. Methods. We immunohistochemically analysed pancreas biopsy specimens of 13 recent-onset patients. Results. Pancreatic islets were identified but showed various degrees of reduction in beta-cell volume in all patients. Out of 13 patients 6 had insulitis. In these 6 patients Fas was expressed in both the islets and infiltrating cells but not in either cell type in the 7 other patients without insulitis. Double immunostaining showed that Fas was positive in 92.2 to 97.7 % of beta cells but only in 17.6 to 46.7 % of alpha cells in Fas-positive, insulin-remaining islets. We found FasL was expressed exclusively in islet-infiltrating cells in patients with insulitis. Double immunostaining revealed that the most prevalent phenotype of FasL-positive cells was CD8, which was followed by macrophages and CD4. Conclusion/interpretation. The interaction between Fas on beta cells and FasL on infiltrating cells might trigger selective apoptotic beta-cell death in inflamed islets, leading to immune-mediated Type I diabetes.

    Notes: Abstract The immune response is regulated not only by the proliferation, differentiation, and activation of cells, but also by programmed cell death, called apoptosis. Fas ligand expressed in activated T cells binds to its receptor, Fas, and induces apoptosis in target cells. Two mouse mutations that cause autoimmune disease, lpr (lymphoproliferation) and gld (generalized lymphoproliferative disease), are mutations in Fas and FasL genes, respectively. Human patients showing phenotypes (Canale-Smith syndrome or autoimmune lymphoproliferative syndrome) similar to those in lpr mice also carry mutations in Fas. This is a good example of a case in which the identification of a mouse mutation has led to the understanding of a human disease.
