Abstract
  • BACKGROUND: It has been recently demonstrated that apoptosis is involved in beta-cell destruction in the NOD mouse model of diabetes. The aim of the present study was to investigate whether IL-15, a cytokine involved in the modulation of the apoptotic process, is capable of modifying the natural history of diabetes and/or insulitis in pre-diabetic NOD mice. The rationale for the use of IL-15-IgG2b recombinant cytokine is related to its long half-life (28 +/- 4 h). METHODS: At 10 weeks of age, 2 groups of 24 female mice were treated with single or multiple i.p. doses of IL-15-IgG2b respectively. As control, 2 groups of 24 age- and litter-matched female mice were injected intra-peritoneally with single or multiple doses of insulitis were observed in all treated and control mice. CONCLUSIONS: We conclude that IL-15-IgG2b reduces the cumulative incidence of diabetes, without affecting the extent and severity of the insulitis process. Considering this and the well-defined anti-apoptotic effects of IL-15, we suggest that the reduction of diabetes incidence could be due to a down-regulation of beta-cell apoptosis.
