WebJan 1, 2011 · Insulin resistance and type 2 diabetes are now recognized as chronic inflammatory diseases. As β-cells in the pancreas work to produce more and more insulin, metabolic stress signals recruit monocytes to clear dying β-cells. These recruited monocytes differentiate into TNF-α, IL-6 and IL-1 producing macrophages that promote … WebThe insulin stimulatory action of FFAs is responsible for the fact that the vast majority ( approximately 80 %) of obese insulin resistant people do not develop type 2 diabetes. …
