Heightened interferon-alpha/beta response causes myeloid cell dysfunction and promotes T1D pathogenesis in NOD mice.

Increasing attention is drawn to the contributions of abnormalities in both innate and acquired immune responses to the pathogenesis of autoimmune diseases, such as type 1 diabetes (T1D). Dendritic cells (DC) are critical immune cells linking innate and acquired immune responses and previous studies in NOD mice suggest abnormalities in these cells. To address DC dysregulation we examined kinetic global gene expression in NOD and B6 GM-CSF/IL-4-induced bone marrow-derived DC following lipopolysaccharide (LPS)-stimulation.
