Flt3L-Derived Antigen-Presenting Cell Transfer in Neonatal NOD Mice Reduces the Incidence of Type 1 Diabetes

Neonatal transfer of immature dendritic cell-enriched Flt3L splenocytes significantly reduces the incidence of type 1 diabetes in female NOD mice. Early time points are associated with accumulation of anergic T cells. In adult mice, there is a reduction in CD4 T helper 1 cells and reduced proliferation and perforin of CD8 T cells. Our work demonstrates how targeting the neonatal window of tolerance alters autoimmunity outcome.
