Prevention of Diabetes in the NOD Mice Reconstituted with Bone Marrow Cells from Allogeneic CD4 Knockout, CD8 Knockout or B-Cell Knockout B6 Mice
Y. Huang, H. Xu, Y. Wen, S. Ildstad
University of Louisville, Louisville, KY
*Purpose: Type 1 diabetes (T1D) is an autoimmune disorder characterized by destruction of the pancreatic beta cells by both humoral- and cell-mediated immune mechanisms. Transplantation…
