The increased release of MCP-1 was observed from pancreatic MIN6 β cells under diabetic conditions, leading to the enhancement of macrophage infiltration into pancreatic islets. And increased endogenous oxidative stress in β cells could be related to its underlying mechanism. In addition, the release of MCP-1 and VEGF was also found to be increased from 3T3L1 adipocytes. The enhancement of endogenous oxidative stress was similarly speculated to be the pathogenic mechanism of their increased secretion, and in terms of released MCP-1, we deduce that the IkB- dependent pathway is, at lease in part, important as a common distal signaling in both pancreatic β cells and adipocytes.
