Aims/hypothesis The endogenous production of stromal cell-derived factor-1 (SDF-1) in beta cells in transgenic mice attenuates the development of diabetes in response to streptozotocin. Here we propose that beta cell injury induces SDF-1 production, and the SDF-1/chemokine (C-X-C motif) receptor 4 (CXCR4) interaction auto-activates Sdf1 expression, resulting in the autocrine production of SDF-1 by...
Aims/hypothesis Stromal cell-derived factor-1 (SDF-1) is a chemokine produced in stromal tissues in multiple organs. Earlier we reported on levels of SDF-1 and SDF-1 receptor (CXCR4) in the insulin-producing beta cells of the mouse pancreas and determined that the SDF-1/CXCR4 axis is important for beta cell survival through activation of the prosurvival kinase, protein kinase B (AKT). Since AKT is...
