We identified and characterized a novel defect in β-catenin expression in bone marrow derived dendritic cells (BMDC) from NOD mice, a model for human Type I diabetes. This protein is expressed at high levels throughout the lifespan of the mouse and correlates with increased pro-inflammatory cytokine production by the BMDC and IFNγ induction by T cells cocultured with the BMDC. These defects, including a similar pattern of pro-inflammatory cytokine production, are also observed in human monocytederived DC from diabetic patients. After exploring several potential mechanisms involved in the accumulation of β-catenin in NOD BMDC, we found that β-catenin is phosphorylated …
