In type 1 diabetes (T1D), the breach of central and peripheral tolerance results in autoreactive T cells destroying insulin-producing, pancreatic beta cells. Herein, we identify a critical sub-population of dendritic cells responsible for mediating both the cross-presentation of islet antigen to CD8+ T cells and the direct presentation of beta cell antigen to CD4+ T cells. These cells, termed merocytic dendritic cells (mcDC), are more numerous in nonobese diabetic (NOD) mouse, and when antigen-loaded rescue CD8+ T cells from peripheral anergy and deletion, while stimulating islet-reactive CD4+ T cells. When purified from the pancreatic lymph nodes of overtly diabetic NOD mice, mcDC break peripheral T cell tolerance to beta cells in vivo and induce rapid onset T1D in young NOD mouse. Thus, the mcDC subset appears to represent the long-sought APC responsible for breaking peripheral tolerance to beta cell antigen in vivo.
