Webonly in part due to the presence of CD4+CD25+ regulatory cells, as graft rejection was also significantly delayed in recipients with CD4+CD25−CD45RBlo T cells (MST = 63 days, p = 0.0018). As controls, 100% mice injected with CD4+CD25+ T cells were tolerant. These data suggested that, on a cell-per-cell basis, T cells capable of inducing WebApr 1, 2005 · Autoimmune destruction of pancreatic β-cells arises as a result of a loss of tolerance. Regulatory T-cells, particularly subsets of CD4 + T-cells, are essential for maintaining self-tolerance. Several forms of regulatory CD4 + cells are known: in vitro−generated Tr1 and Th3 and naturally occurring CD4 + CD25 + cells. Regulatory …
